Physics - Tech engineering software, that is fun?

Hi, Just a quick question... I ran across something called Gmod, or Garry's mod software today by accident. This one here... http://www.youtube.com/watch?v=Ui7S1ToK49Q&feature;=related It looks pretty neat, sort of a mechanical play thing. But, I'm not sure how true to reality the software is, also you apparently need to own a main platform software to use it, like Half Life. I don't have any of the games needed to play around with Gmod. I started to wonder if there is any other software out there that works as an, across the board experimenter's virtual lab? Sort of a mechanical, electronics virtual plaything? I'd think that engineering tech schools would have software such as this, (CAD comes to mind) but I didn't quite find what I was looking for with a google search... Not exactly sure what the best search term would be for something like this? I've come across virtual electronics software, but maybe I'm asking too much for a multi electro-mechanical environment. Has anyone ever used software like this, particularly something fun to play around with, without being to dry? Free would be nice as well, but I'm probably pushing the envelope there a bit! LOL.

Simple Design and Digital Prototyping Software

Hi guys. I've been making some very simple mechanisms for a steampunk Instructables series I've got planned, and have been prototyping using cardboard and paper. This has actually worked really well, but I'm a fan of the digital realm, too, and was wondering if anyone could recommend some simple, cheap (ideally freeware) digital prototyping software to help me eliminate (or minimize) the paper and card phase? As I say, the mechanics are very simple. Cams, pulleys, levers, gears -- nothing more complex than bell cranks, linkages and basic drives. I think a scotch yoke is about as adventurous as it's got so far. So I'm looking for some nice simple software that'll allow me to build and test the mechanisms digitally, if such a thing exists. I've looked at the likes of Autodesk and Blender, but they seem like a sledgehammer to cure a headache. Even something that runs online in a browser, or an iPhone/iPad app would be good (I've played some physics-based games on the iPad that would almost be ideal if they weren't puzzle games!). Any advice? Cheers guys!

AutoCAD for Mac Survey

AutoCAD was the first CAD package I really felt comfortable using and designing in. I've since realized that part of being an engineer is being familiar enough with dozens of different CAD packages so that you can recognize which one is the best tool for the specific challenge at hand. Since I use a Mac, I keep a copy of Windows running under Parallels primarily for CAD packages. This is actually a pretty common theme with people working at the various Squid Labs-related companies. I could probably walk just a couple of offices down and see SolidWorks on a MacBook Pro screen right now.So, I'm happy to read that AutoDesk is asking for input on a version of AutoCAD for the Mac:Mac Fanbois Get their Wish: AutoCADNearly two decades ago, Autodesk abandoned AutoCAD on the Mac. But now perhaps it is seeing too many sales lost to the likes of ArchiCAD to architecture clients, NX to mechanical engineering customers, and SketchUp to designers. Autodesk marketing calls it "trying to stay in tune with our customers," and are asking Mac and AutoCAD users to fill out a survey. ..."

unfinished,5 DOF Robotic Mechanical ARM

5 DOF Robotic Mechanical ARM Required Material of project:- 1. Basic Servo Tower pro 9g*4 2. Header pins Male female*2 3. Arduino Nano*1 4.10kΩ Resistor resistance*2 5. Trimmer Potentiometer track Linear; maximum resistance 10kΩ*4 6. Tactile push button*2 7. Blank circuit board*1 8. Acrylic strips for Robot & potentiometer body*2 9. Wires, Button, Switch 10.Balsa wood, Metal, Plastic Procedure:- Arrange all necessary items.. Please go through the attached images  for better understanding.. I divide whole project in two parts 1) Servo Motor assembly 2) Potentiometer assembly 1) Servo motor assembly: – Servo motor as J1, J2, J3, J4 fix the servo motors as shown in image use 3M tape to glue servo, use thin flexible plastic strip to make griper, make hole in center of each finger tie thread in that hole pass this thread from center hole and tie knot at the other end of thread with 4th servo motor’s knob, as you stretch thread finger get close vise versa. Fix whole arrangement on strong rigid base. 2) Potentiometer assembly: – Fix potentiometer as shown in figure name potentiometer as do previous R3, R4, R5, R6 this time place R6 separately for easy access this potentiometer control gripper to pick and place. Potentiometer arrangement symmetry must be same as servo arm. Fix whole arrangement on strong rigid base. Moving a little bolt from one side to the other side:- 1. Actuators / output devices: 4 micro servos 2. Control method: controlled by a PIC16F690       assembler firmware 3. CPU: PIC16f690 micro controller 4. Operating system: self made assembler code 5. Power source: 4.8V to 6V from 4 battery cells 6. Programming language: PIC Assembler 7. Sensors / input devices: teach in system with                         4 potentiometers       Making Processer:- The Potis are standard types and are screwed to the white plastic parts with their nuts. The axles are pressed into the transparent plastic part. The handle to move the teach-in-arm is a M3-Spacer and the socket is a plastic part with is normally used to fix balloons on a stick to hold it.                     move the motor itself by hand a little force is needed due to its permanent magnets, which create a small holding force. But inside the servo a lot of gears increase the force which you have to apply. If you move the servo by hand, you have to apply a much higher force. If you overcome the motors holding force, it starts to rotate an acts as a flywheel. So moving a servo by hand needs a high torque and its not easy to turn it to the position where you want it. ( Fan control modules for engine cooling of real cars have some extra parts to clamp the voltage which is generated, when you drive at higher speeds. In that case the fan works like a windmill and creates higher voltages than normal inside the power stage of the module.) And there were also a lot of other "problems" which had to be solved using my PIC Controllers. i.e. self made electronics for a RC-Excavator which works similar to the digital system used in slot cars. To replace a lot of wires between the rotating part of the excavator and the track unit, a small PIC 12F629 reads the pulses from up to 5 channels of a RC-Receiver and leads their information via a 2 wire connection to a second PIC12F629. At the second board the power is separated from the data. The PIC is reading the data, and generates the PWM output for the 5 Servo output connector. the 2 wire connection is made with a cheap 6,3mm mono microphone plug which is also used as the axle for the rotating part. The arm of the excavator is also powered by standard servos and so it was necessary to change the control behavior from proportional to integral so that the servos move like real hydraulic cylinders which are controlled by valves. I used the same 12F629 type for that job and added some features like adjustable limit positions and starting point programmable by one jumper, and automatic return to park position when missing the pulses for some seconds. The Software is simple:- Its working like a servotester for four axis. That means, every poti is connected to an analog in of the controller and all servos are connected to GPIOs. The controller reads each poti, does some scaling, so that the angle of the poti equals to the angle of the axis and finally he creates the PWM output 1-2ms pulse every 20ms for all servos. Teach mode:- After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array. Play mode: The sketch reads the array step by step and moves the robot arm. For cool looking movements I added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed.           The program moves the servos at full speed to the next position and a short delay time after each command allows all of the servos to reach their final position. That means that it is possible to increase the speed a little bit more by doing some fine tuning of the delay times after each command. The final thing which is still not implemented is the routine which saves the "Teach In" data 5 or 10 times per second, so that the controller is able to replay it in a loop with the original speed or with a lower or higher speed. Electrical Connection:- Provide separate power supply (5V DC 1amps) to the Servo motors . Don’t forget to short ground of both power source ( arduino + servo) 5 DOF Robotic Mechanical ARM :- 1. Use of Fiber on upper side 2. wooden spoon is a part of side body 3. cable tie *12 pieces use the robotic. 4. Some pices of wires 5. use scraw*4 6. Glue 7. some small clips Because to attached body 8. small size of plastic box 9. One pieces of  square fiber stand and one pieces small & medium  circular fiber  10.  L293D Motor Driver IC+IC Base KG143 11. Generic Elementz High Quality Nickel Plated 24*18 Points Bread Board*(2 pieces) and one plastic 12. Push Button Switch. Play Mode version 1.1 The gripper input is used to set the delay (0,1,3,15,60,300 seconds) after a loop is done. The switch (it was left from the project start) pauses the robot.        Thanks you:

Bug, Suggestion, Feedback! Community sections

Since there is no place for it right now I just created a topic for the purpose of collecting bugs we find.Let me start with a little list I collected so far:1. Confusion!When I create a new topic I need to select a category and channel.So where exactly are these categories and channels?Somehow I struggle to find them anywhere else than in the two drop down menus when creating a new topic.If we have all those drop down options then why can't we make proper use of them?2. List problems!I know there is planned work on the way we see the cummunity section but still...When I create a new topic then it seems to be nowhere.I check again a few hours later and still nowhere.Next day often the same storey.Where does a new topic go and when does it appear in the community section?3. Sorting - this one is already being worked on I guess.We really need a working option to sort postings and replies by time and date and relation.I get notified about a reply and check...Hmm, about 80 replies and somehwere, someone wrote something new...Good if you can copy and past a part of the preview to search for it in the browser manually...Comfort and logic is needed to replace the current confusion and inconsistences.As for suggestions to get the section up to what what both developers and users turn into happy campers:1. Editing options!!!For years this is my number one that not just got more and more ignored but also reduced to nothing.Anyone creating a topic should have direct control over it.This means beain able to create the post in a way the poster sees fit for the purpose.The basic text editing options any Vbulletin or PhPBB board would offer should be available here in a similar way.Embedded text and images in the size and place that fits - either by posters choice for the size on the screen or by providing a fixed sized preview that opens a fullsie view when clicking on it.Code is more important these days than back then when I first asked for option to embed it here.Tags are useful for a lot of things.Add a quote from a previous post or reply, add a code window that allows proper copy and past action for both poster and reader (preferably with highlighted syntax like in Notepadd++, ....You can only provide dedicated help if you have the right tools for it.And you can not ask for dedicated help if you can even properly post the problem due to restrictions and limitations in the editing system.Coloered text, other than for code is not really required but all the basics anyone knows froma real forum would be a great addition.2. Tagging or otherserwise highlighting the areas of the topic.If I already create a post in the technology section than it would only make sense to see a corresponding icon next to the topic in the community section.Same for coding help, mechanical problems and so on.The current sections and categories are outdated and a lot of things are missing.Mabye not in terms of Intructables but certainly for the community sections.3. Structure....Currently it is all one big blob and not even the sorting works (yet).This is perfect for people like me wanting to quickly check if something new was posted but not so good for someone trying to have some fun browsing.Imagine you want to spend some quality time checking what problems people have or what help they seek when it comes to woodworking.No search options, no list options, no categories to explore.Back in the day we had a few sections and a basic sorting option, like by most recent.Someone only interested in helping with coding on Arduino wouldn't even bother here and move on.On the other hand, people with no clue how to fully specify their problem might find a solution just by browsing through the corresponding section.4. Linking Instructables....I don't know the reason for it or the idea behind it but why again is the question section filled with Instructables?And why look lot of Tips like Instructables?I mean if it is for the user to find stuff than it might bind him on the website, but I doubt it will be satisfactory for the user.Questions or tips in regards to an Instrubale should be there- with the Instructable but not in the community section.Add it a tab for the Ible instead...I see little to no point in answering to a question someone has in regards to a specific Ible unless "I made it"....5. Voting and closing...When it comes to forums then one thing all have in common: bloat.People only register to post something but never come back.Topics are solved, done and dusted.Topics gone dormant for months or even years.Great answers or vital details get lost.The list goes on....What it comes down to is that order needs to be restored and maintained.Open an archive section and start moving out.Topics of certain age and with no new replies - gone.Topics where the user never again logged in - gone.Topics voted or request to be closed, closed or gone to the ariche as well.Topics voted to be of general interest pinned somewhere for easy reference - like this one ;)A thread starter got his answer and is happy? Then for crying out loud let him vote or credit the best answer and close the topic.More than three people voted or tagged a topic as useless, not possible or similar - close it so it can one day go in the archive section too.All this and more should create a community section that once again can become an active playground for everyone.A place to seek and find help.And who knows, maybe some of the good old guys might even consider a return and more time spent here....

Any other engineers have trouble getting used to 123D design?

I'm wondering if anyone else who has experience with professional CAD software has tried 123D and finds it difficult to use. I have ~7 years of experience using Solidworks in a mechanical engineering and robotics context. I recently tried to pick up 123D for use with my home 3D printer and find it absolutely infuriating to use. It feels like working with oven mitts on. But, I see screenshots of very complex models people have made all over the place. So, I'm not sure if: - I'm spoiled from the use of "professional" software and need to lower my expectations for free consumer software. For example, I'm very used to full control over creating reference geometry like axes and planes, and creating everything from 2D sketches that are then extruded/revolved/swept (as opposed to 3D shape primitives) and having direct control over all of the dimensions the entire time. In 123D I find it difficult to do something as simple as create two rectangular prisms and put them a fixed distance from each other, or create a rectangular prism and then put a hole in it a certain distance from one edge. - If this is just a difference between Autodesk and Dassault software - e.g. if I was used to using Autodesk Inventor instead of Solidworks, maybe I'd have an easier time picking up 123D. - If I'm just being lazy/impatient, and need to watch more tutorial videos and give myself more time to pick up the software. So, just curious if anyone else has a similar experience coming from using professional software (as opposed to a maker/hobbyist who had never used 3D CAD at all before).

My full Idea (Don't know if feasable) is to use the turn by turn information of a smatphone navigator that uses GPS (like the one of google maps) to activate one of two vibromotors, there would be one vibromotor on the right arm and the other on the left, if a next turn is needed to be made (info from the navigator) a signal will be send to the the motor on the left arm, It will vibrate and let the user know that this next turn needs to be done. I need urgent help since I don't know which components I may need and how to develop the software or anything I will appreciate any hint.

Electromagnetic levitation via a grid of magnetic "pixels"? Let me clarify...

 An idea popped into my head a few months ago whiles reading about superconductors and how they create a magnetic "mirror image" of the magnet levitating above them. I imagined a grid of small electromagnets arranged similar to the pixels of a computer screen, each one individually controlled by a computer. Some sort of sensing mechanism, of equal resolution to the grid, would detect the magnet's flux at any given point and send that to the software. The computer would model, in real-time, how it must adjust the magnetic grid to compensate for the momentum and weight of the unique magnet floating above the grid. Basically, the software would mirror the magnetic field to allow for perfect stability and even maybe some level of control by offsetting the stability slightly to make the magnet move across the table. So is this even possible? Does it already exist? Do I get a cookie? *Target all weapons on that idea and FIRE! Shoot it down.*

Looking to have small 3D printed pieces made

I am constructing an actual working version of the locket from The Illusionist. All of the ones that I have seen done try to make a different mechanism than is "displayed" in the movie, but none of them do it right, in my opinion. It has to be quite small, and it has to be intricate. I have come up with just the mechanism so that the two halves can rotate and slide across the same axis, just like in the movie, but in order to get it to work properly, the dimensions need to be precise, sturdy, and retain fluid movement. This I cannot do with wood. as small as these pieces need to be, plastic is the only medium I can use and still be exact, and a 3D printer is the only thing I can think of that will easily achieve this. The problem is that I do not possess one of these printers, and hence need your help! I also will be needing to work with you to design the pieces on the software side of the printer. I have it all in my noggin, guys, please help me bring this to fruition! Thank you! Ged

Embedded video solutions

I'm working on a project that requires the playing of short videos based on some physical conditions. The microcontroller and more general electronic end of stuff I'm fine with. What I haven't yet figured out is the mechanics of the video player mechanism. I want to use digital video stored on removable media (preferably CF or similar memory card storage). The videos will have no sound, be black & white, and probably low resolution (640x480 being the max size). I had originally planned to use an embedded linux system (gumstix verdex or some such thing) hooked to a TFT display. With some software running on the computer, it shouldn't be hard to control with serial communication. However, I'm not sure how well (if at all) mplayer would run on the Verdex. Also, if there's a cheaper solution I'd rather take that. I guess this post is to see what my options are. I know there are mp3 decoders on a chip (like the STA013) that produce output that you feed more or less directly into a DAC. Is there such a thing as a hardware mpeg video decoder (or divx, or quicktime, or avi, or whatever?) If something like that existed, I could connect the CF reader straight through my uC to the hardware decoder and pipe it out directly. Either to LCD or CRT (depending on which signal is easier). So, does this exist? Is it feasible? Thanks,

Idea: motorized cocktail shaker (for a real Ramos Gin Fizz)

There are a couple of motorized martini shakers on the market, but neither of them shake hard enough. I'd like to make one that would simulate the actual motion of a good bar tender. The traditional way to make a Ramos Gin Fizz requires shaking it for 12 minutes. I don't have that kind of endurance. For a martini, I'd like the machine to shake hard enough to chip the ice and leave frost floating in the drink. 1. I'm wondering if an electric drill would be capable of driving this thing with modifying the gearbox. I have no experience creating or modifying gearboxes and would like to avoid that if possible. 2. Anyone out there have (or want to make) a good video of a bartender shaking the hell out of a cocktail? (There is a difference between a casual and an agressive shake.) It needs to be from a perspective perpendicular to the plane of motion. This will allow me to trace the path and recreate it in CAD software. 3. The most exciting thing about this is designing the elliptical mechanism that would produce the realistic shake. I've never done animation in SketchUp. Can it handle gears and levers? Is there something else that you recommend? (no windows software please) I'd love any suggestions you have on any part of this.

Computer controlled switch?

I am looking to close a circuit using software on my pc, and if possible through the network but worse case I can connect to a specific pc. I have a door mechanism that opens when a certain circuit is closed, so I want to be able to control that door from my office.  I can do any wiring or add a circuit board to a pc that about 15 feet away. I was thinking some kind of circuit board, or even splicing into a serial port or parallel port and connecting that to the PC.  Then on the PC i would need some kind of program that all it would be is a button that when I press it, the circuit is closed, either for the duration I'm holding down the button, for a certain amount of time after the button is pressed or anything really. I'm no electrical engineer of software programmer, but I have a base understanding.  I am in IT and know how to solder and basic programming. My ultimate solution would be some logic board that has an RJ-45 connection that I can give an IP address so I can open the door from any computer on the network and two pins/connections out to close the circuit.  Sending a command to the board from command line would be just as well as a small program that displays a button. Thanks in advance.

I want to print some gears, but I dont know how to make them

So I'd really like to make some geared mechanisms to be printed out, but the math is a little bit beyond me. Right now I have 123D and it does not have a gear generator. I was thinking that somewhere there has to exist a catalog or database of pre-designed gear stl files. I was hoping that somebody here might know of such a thing, or perhaps another way to easily make gears? I've been seeing all kinds of crazy gears made into really exotic shapes, but I don't know how these are made either. I'm assuming that the people that designed them are super geniuses, or that they have some kind of advanced software. Which is it?

Need a USB-Controlled lock box

Google led me here, and I have to say that I'm very impressed with the ingenuity of the people here! Hopefully someone here can help me. I'm trying to find a USB-controlled box. The box can be quite small, as it needs to contain just a single key. As for the USB part, I can go two ways: first, I would need the state of the box lid (i.e. open or closed) to be sent via USB to the computer. Or, the second alternative would be that the box lid would only open if a certain signal was received via the USB cable. I can do the software programming to either send or interpret the signal, it's the mechanical part I can't figure out. I would happily pay someone to build this for me. Any suggestions? Thanks! Lee

Ideas for a Teleoperated Project

I want to make my first Instructable, and I would very much like to do a project that is teleoperated via the internet. I have strong web application and embedded software skills, so I am doing this to combine the two with a web control panel and whatever the project will be. However, my mechanical and electronic skills are lacking (yet not absent). Does anyone have an idea of what the physical end of the project should be (what should be controlled)? At first I was thinking about doing a remote controlled car, but that is not original enough. I am looking for ideas of things anyone that goes to the site can control, so something that would be OK to give control of to the public. Thanks for your help, I will give credit to whoever comes up with the idea.

My Autodesk Residency

I was an Artist in Residence at Pier 9 from January through March of 2014, just a few months after the facility opened. I completed three projects during my residency, but split some of my projects into several Instructables. Citrus Juice Press with Mortise-and-Tenon Joinery "Tiny Planet" 3D Printed Mechanical Sculpture "The Manhattan Project" Cocktail Machine (Coming Soon!) Here are some things that were wonderful about my Residency: -Vanessa and Noah were extremely supportive as coordinators/facilitators/etc. They worked tirelessly to organize and improve a rapidly growing program filled with newbies like me. Whether it's just bouncing ideas around or getting connected with a person who has a particular skill, they were always willing to take a minute and help out. -Shop staff and Instructables staff were very helpful in navigating the tricky details of the shop, writing and publishing Ibles, etc. I relied heavily on help from Sean, Gabe, Dan, and Martin to help me work with tools in the CNC, Metal, and 3D Printing shops. They were patient and interested in helping me become a skilled operator. -Having access to the tools at Pier 9, particularly the Omax Waterjet and the Objet 3D Printers, allowed me to quickly move from design through prototype to final product. As a mechanical sculptor, I am used to spending months on a single project, waiting days or weeks for waterjet/lasercut parts to ship to me, etc.  -Classes and workshops, both formal and spur-of-the-moment style, gave me the resources to use so many tools that it was sometimes overwhelming (see below), but always awesome. Gabe's weekly software sessions, Audrey's photography tutorial, and of course all the Safety and Basic Use classes in the shop, were excellent ways to gain experience with new tools or learn how to better use familiar ones. -Free, endless coffee. Here are some challenges I faced during my residency: -The open-office style space at the Pier makes it quite difficult to focus (for me at least). Wearing headphones can help, but I also found that doing computer work elsewhere was more efficient. I know that the layout is meant to facilitate community, and it does, but I have found that I have to be vigilant so that my "talking about doing cool stuff" time does not eclipse my "doing cool stuff" time. -CNC tools can do incredible things very quickly, but they are fickle and, especially in the hands of novices, break often. Other times, they are just so popular there is a line to use them. Shop staff do a superb job of keeping the shop running smoothly, but I learned to always head to the Pier with a list of projects to work on, in case the tool I most wanted to use was unavailable. -There is an overstimulation that seems impossible to avoid at the Pier. New ideas come so fast, it becomes hard to pin yourself down to one and begin the nitty gritty work of actually making it happen. It can be quite difficult. -There is some pressure at the Pier, and I imagine it will grow, to use Autodesk software. As much as I would like to gain experience using Inventor and Maya, I decided that I would get more done by sticking with the software I was comfortable with.  -Free, endless coffee. I walked away from my Residency with a host of new skills, a number of new friends and professional colleagues, and a few projects to boot! It was a great time, and I would do it again in a heartbeat. Thanks Pier 9!

Arduino controlled CNC Coil Winder

Arduino controlled CNC Coil Winder Hello World. This open source project that I am working on. Is an Arduino controlled CNC Coil Winder machine. Since I have the need for precise coil winding, a CNC winder machine is the solution. Machines like the one I am trying to build cost around $4,000-$9,000. I am building a machine with the same quality for under $300. Is hard to believe but is possible. The problem: Get rid of CNC software. I think that Arduino can do the job here. I am able to make it work with an standard CNC solution, but the problem is that I don't want to interact with a computer at all, and I am pretty much sure that an Arduino application can do the job. My progress is on the 85%. I have the mechanical part ready to go. Is the Arduino part where I am stuck. So far, I can keep going on with CNC software, but that is not my goal. I'll probably work on the Arduino solution later, but I'll really appreciate help with an Arduino solution. This is an Open Source Share-Alike 3 project. Cheers!~ Edit: The picture bellow is from a commercial Coil Winder and the only purpose is to illustrate what kind of machine I am building.

Sparkfun CNC parts. Need a head start with project, need help with shopping list.

First off, I know practically NOTHING of robotics and I have a plumber's understanding of electronics.  This has to be a "For dummies" project.  It's also important that most or all of the electronic parts come from Sparkfun, because I wish to take advantage of the great bargain they have coming up and because I cannot find anything locally. That said, I have been looking at building a small CNC milling machine.  Something that can engrave and cut light materials like circuit boards, foam, and softwoods.  I want to at least be able to engrave steel as well, but I feel that is up to the tool attached to the milling machine. The machine itself is not a problem.  I understand the mechanics of it, have the tools and know-how to produce, find or buy all the required parts. The trouble is the steppers, driver, and software.  The more I look at it, the less I understand.  Let's get to the questions I guess.  There's a lot, I'm very sorry. -Are there any well-documented projects here or on the web using mostly Sparkfun parts? -What is typically involved in setting up a stepper controller/driver?  Will I need to flash anything? -What software is best for operating a CNC from a windows or linux PC?  As a printer driver? -Out of the motors available on Sparkfun, which will give me the highest resolution and which will be strong enough to move up to five pounds of material without trouble? I know I need a lot of hand-holding here, but I really want to get started on this and I really want to take advantage of that sale.  It seems like the perfect time to begin.  Please help!

Aspiring techie. Where do I find the skills, the tools, the work?

I want to pursue more things like programming, robotics, working on cars and lighting the neighborhood with massive LED Beacons of custom-PC goodness. I've tried some researching of certain topics on my own, but I usually run into some difficult roadbumps. Particularly, there often runs a gap between beginner and advanced knowledge I find hard to bridge. I started off great with some programming classes at college, but their department is lacking. The other significant obstacle that comes to mind is cost. It's hard to shell out for new tools and parts for every project. Do you have any advice? Where could I find an entry-level job at an electronics re-saler, or something like that? I don't really have the skills for a mechanic, but what might be a first step? Or, something pre-programming that I could learn from- particularly for game or software development? Which schools in the Midwest have more hands-on training?

Convert airgun/Paintball gun to be fired by a computer (12v solenoid valve)

Hi!I have a project this summer where I need to convert a paintball marker and a co2 Airpistol to be fired by the use of a solenoid valve powered by 12v.The project goal is high-speed photography, more or less photographing object being hit by a projectile.What i need is a way to fire these guns precisely by the use of my computer and software, and since I already have plenty of 12 solenoid valves that work with this system I thought my easiest way is to adapt these valve to trigger the guns one way or another.I just purchased a Valken V-TAC SW-1http://www.valken.com/Marker-V-TAC-BLACKHAWK which I plan to use as base (for parts) My reason for getting this particular one was that it was on sale for 50% and seems to be fairly popular as it's based on the Tippmann 98 design.I attached an image of the valve I used with my controller and software (Cognisys Stop shot) now I can probably use any 12v solenoid valve (with the same spec ?) as the one I use now so it doesn't need to be these exact valves. As long as they can be operated by turning on-off power with the same powersource i use to control my current solenoid valves.From my understanding, most airguns use a pin valve, which is hit by a trigger mechanism that is then rearmed by the blowback.What would be the best way to modify an airgun for my needs? Replace the pin valve with a suitable solenoid i can control instead? Or go for a design that uses maybe use a piston and 2-way valve to hit that pin?The gun does not need to be mobile or ergonomic, it will be placed in a rig regardless, however keeping the barrel and keep the Picatinny is preferred to be able to mount marking aids etc. and mount the gun to a tripod.Any tips or suggestions are highly appreciated!Thank you!

Hack my homepage?

Software security issues are often obvious to a second pair of eyes. I just posted the PHP scripts for my personal contact homepage as an instructable:Simple PHP personal contact homepage (web3.0!)Can you hack it? Preferably a copy on your local machine and not on my actual server... I deleted all my administration files and classes prior to making this post, just in case.I have two primary concerns:1. General PHP injection attacks. Proper handling and escaping of form data.2. The admin interface has a sessions based authentication mechanism. Login is compared to a MD5 hash of the password, then a session is created with an MD5 hash of the user's IP address. Each subsequent page load compares the authenticated session IP with the user's IP address (again, an MD5 of both). The goal is to prevent remote session stealing related flaws by tying the session to an (unknown...) IP address. Obviously if you have access to the local machine this is all moot, but there is little I can do about that. If an intruder were to get around the session authentication, they would be able to upload files just about anywhere on my server using the admin upload interface. This is a bit of a concern...I think in light of this, I'm going to add an option to limit the web admin interface to one IP address. My IP is fairly static, and if it changes, simply upload a new config file by ftp.

RFID - Metal blocking receiver issues?

Please can anyone advise? So we've built a prototype that detects when a bottle is opened And triggers a software response. We need to build the real thing next. The prototype: We've used a small passive UHF RFID tag mounted on the lid of the bottle, hidden under foil. When the bottle is opened this tag pops out and can be sensed. We have a long range RFID scanner that recognised the appearance of the tag and send the signal onwards. This currently works ok at a Distance of around two meters. Problems with the prototype: The action of revealing the tag is not very reliable. Currently we've just experimented with various pieces of tape and foil attached to the tag and bottle. We need to develop something reliable that could be applied to a couple of hundred bottles. The range is a bit shorter than we'd hoped as well - ideally we need the range to be over 5 meters. Our reader has the option of adding multiple aerials though which may help. And perhaps we could have a set of readers linked It's not necessary to use RFID if some other way of detecting when the bottle has been opened could be used instead. The reason we chose RFID is that the bottle doesn't need anything very large added to it. We are trying to sell these things after all. We really could do with someone who can help make this system more reliable Both by helping us with improving the mechanism for revealing the tag and increasing the RFID sensing range

The Stair-Climber: My Idea for the Scholarship Contest

My name is Brian Smith and I am a recent graduate of Spring Valley High School in Columbia, South Carolina. I have done research in the field of robotics in the past for science competitions. I will be attending Georgia Tech beginning in the fall. What I would like to do with the iRobot Create is simply to extend the original functionality of the Roomba by allowing the robot to both scale and vacuum a carpeted staircase. From a functional perspective, ideally the robot would clean the first floor of a a two story house for some predetermined period of time, and then climb the stairs, cleaning them on ascent. The robot would then clean the second floor of the house for a predetermined period of time before descending the stairs once more to recharge and then begin the cycle again. As far as implementation is concerned, the first step of the cleaning process is quite straightforward; the robot will clean the first floor randomly using the same or similar algorithms as the Roomba. After the predetermined cleaning period for the first floor has elapsed, things get a bit more complicated. The robot will then seek out an infrared beacon marking the base of the staircase to begin ascending/cleaning the stairs. For this task, the mechanics of the system will be just as important as the software. Essentially, the robot must square itself with the first stair at which point it will deploy its equipped "stair rails" which creates a ramp which the robot can use to ascend the first stair. The robot then collects the rails, cleans the first step, and redeploys the rails to ascend the second step. This process continues for each step until the robot reaches the second floor of the house. The then robot resumes random cleaning of the second floor. By similar principles, the robot then descends the stairs and finds its recharging station on the first floor. Although I feel that this project will be challenging, I also feel that it is reasonably within my capabilities to be completed by the deadline.

Kaysan Stepper Motor ( Motor Shield or Easy Driver ) ? How to stop motor after rotation?

Hello, I am Mechanical Engineering student working on my Intro to engineering class project. We are a group of two students ME and EE but unfortunately my EE partner dropped out of class and I have to finish the project myself. The project is about rotating some sort of pipes. I have not figured out where to place the electric motor but all I am working on now is setting up the circuit and the motor. I have a kaysan stepper motor nema 17 Datasheet link :  http://www.kysanelectronics.com/Products/datasheet_display.php?recordID=7850 I am planning to have the motor rotate one or two rotations in only one direction and then stop. When a push button is pressed the motor will start rotating the one or two rotations. I did some research and I found out that I need a motor shield or Easy drive to control the motor. So far I have the following items: 1. kaysan stepper motor nema 17. 2. Arduino Uno Board. 3. Adafruit Motor Shield v2.3 4. Easy Driver Shield Stepper Motor Driver V44 A3967. 5. Push buttons and the circuit board. I am really not sure what is the best to use between the Adafruit Motor Shield and the EasyDriver. What is best suitable for my application ? and in terms of the Arudino code how do I make the motor stop completely after specific number of rotations. I have the Stepper Motor connected to the Arduino and I tested it using the Example code in the Arduino software but I am not really sure how to make the motor stop completely? As of the power supply, I am planning to use an external battery buy not sure what voltage I need. Your help is really appreciated. Thanks

Turn dial to generate pulses

Here is my proposal. I'm building a pan/tilt unit. I plan to have a 200 step motor attached to a 20:1 worm gear, (the latter is needed so it will 'lock' in place, and not be solely reliant on the motor's holding torque.. So in order for the output shaft to turn 180 degrees needs the worm gear to turn 10 times. In turn the motor must do 10 revs, which would need 2000 pulse steps. It's the pulse generation that's proving difficult. Whilst a 555 timer could generate pulses, I want it to be 'mechanical' For example, if I turn the knob 90 degrees, I want to create 1000 pulses, (45 degrees creates 500 pulses) and so on, so the knob matches the physical position of the camera. If I turn the knob 180 degrees in 1 second ... the motor will turn 180 degrees in 1 sec. If I turn the knob slowly, pulses will be generated slowly, and the camera/motor will turn slowly. My idea at present is some sort of optical encoder ... but that would need 4000 divisions on the wheel!! Or - a 1024ppr wheel with a 1:4 step up gearing ... but such encoders are several hunderd Pounds!! And I would need two of them!! I have software that will allow me to print an encoder wheel, but resolution will have to be 'course' since it will use an LED / transistor, so I suspect around 64 divs. I purchased a RC servo, wondering if I could remove the motor, and turn the output shaft by hand. Couldn't be done. I've also considered 'planatary gears' in reverse to 'step up' the revs ... but I cannot locate any 'hobbyist' versions other than the Tamayia type. Also briefly looked at RC servos, but having done the maths, it would be impractical to get the output to move (say) 0.1 degrees as the motor would only move about 1/4 of a rev and have no torque!! (One option may be to make it continuos rev, and place a feedback pot externally.but again, moving 0.1 degree around a pot would create minimal feedback) Incidentally, 0.1 degrees is the stepper resolution 180 degrees / 2000 steps Anyone any ideas? Bearing in mind that the speed of the pulse train is dependant on how fast the control (pot) is turned, and also matches physical camera position. Encoders are preferred option as it's then possible to electronically guage which way the motor is turning. If electronic, here is (sort of) what the circuit would need to compute. (Sample and hold?) Moved from 0 to 45 degrees in one second. That degree of movement needs 500 pulses, thus need to generate a pulse width to get 500 pulses in 1 second timescale. ** This is just to give an example. The actual sampling rate would be much faster. If it was a 'slow' 1/10th second, in the above example it would check every 4.5 degrees, and generate 50 pulses in that time scale.

Suggestions for a cheap, simple robot unicorn build

My 5yo daughter has figured out that her mad-Scientist daddy can make crazy things come true.  For her birthday, she got a real unicorn and a princess crown (see picture attached).  Now for Christmas, she has her heart set on a ROBOT unicorn, and I think I'm going to try to tackle this, but I need to keep the scope tight so that when Christmas arrives, I'll have a deliverable for her. (My instinct always leap to grandiose ideas like actual quadrupedalism that would balloon the time/effort/money inputs into the stratosphere.   My biggest obstacle to make this work for Christmas is to stick with K.I.S.S. principles.  I can do basic welding, woodworking, fabricating, stitching, etc.  I'm reasonably good at electronics, and am a professional programmer with a degree in Aerospace Engineering.) Here is my rough  build plan:  (Completely open to improvement suggestions) 1)  Build frame out of 1/2" square steel tubing and weld together.  Leave large torso cavity for electronics and batteries.  Feet will have wheels concealed by a hoof shroud.  Feet will be upgradable (see tech features below) 2)  Use blue foam to rough out body shape.  3)  Cover with about 1/2" of soft foam covered with felt.  Use yarn for mane and tail.  Cover should be removable and washable. I'm trying to figure out tiers of work so that as long as I get the basic frame and covering down, I'll be able to increase/decrease the scope to ensure I'll have a deliverable for Christmas.  Here are the tiered robotic features I am envisioning: Tier 1: Make the saddle bounce at about .5Hz with an amplitude of roughly 1/2".  Possibly make head/neck bob up/down in sync. Tier 2:  Add horse sound effects Tier 3:  Build sensors for the reigns and stirrups.  Monitor if stirrups get pushed inward in a basic kick the horse motion.  Monitor if one reign or both are being pulled.  Make sounds effects based on inputs.  (E.G.  Clop, clop of hooves begins when stirrups are pushed in, and stop when reigns are pulled.)  NOTE:  Since they have access to real horses, keeping the controls reasonably close to riding a real horse will make this double as a trainer/simulator for her and her friends. Tier 4:  Upgrade wheels to powered.  Move based on reign and stirrup inputs.   Max speed will be very slow (40fps or so), so that it can be used inside safely.  Movement is mostly just to augment her imagination, not to move like a real horse. Tier 5:  (Not much chance I'll get this far prior to Christmas)  Upgrade software, sound effects, etc. Current back of napkin ideas: Frame will probably have 3 pieces: legs/torso, neck/head, Saddle/back  Saddle/back removable for electronics access. Neck/head will be joined to torso in 3 spots:  the top point will be anchored with a chain link between two eye-bolts, the other two points would be on the sides of the bottom, with compression springs pushing the neck and torso away from each other, limited by a mechanical linkage.  This should give reasonable motion ability, and allow the two base points to become the sensors for the reigns being pulled. I'm thinking a small 12V deep cycle battery, and 12v salvage DC motors powering the wheels.  Depending on the motor torque, I'll either power the back two feet and keep the front feet as swivel casters, or power all four and turn tank-style. The budget needs to stay reasonable, say $100ish.  This is a kids toy, and I've got lots of other mad-scientist projects to pump money towards. Outstanding questions: Motor selection, cheapest with high enough torque Good, cheap way to make seat and possibly head oscillate.  Mechanism needs to not break even if a 200lbs rider sits on it.  (Doesn't need to work when overloaded, just can't be permanently damaged when overloaded.) Locate inexpensive 12v charger that won't overcharge if left connected, but will charge a 3ah battery reasonably quickly.  (Or schematics to build one)  Essentially, looking for a best bang-for-buck charger. Least expensive way to play audio clips?  I've got plenty of horse-sound clips located, but I need a way to play them economically. Not sure how much force will be needed for movement.  I'm assuming a 70lbs rider/robot max and that it will primarily operate on flat surfaces, potentially on carpet.  Can't burn out if overloaded.  Suggestions on simplifying this?  Suggestions on simple improvements?  Ways to keep the costs down?  Sources for economical parts?

How to make Flip Clock Numbers and build a "like"-counter around it?

Hey All So I've got this client, who's absolutely crazy about the "FLIKE" (A physical like counter.). But he can't have it for another couple of months, and he'd like it to be a little more custom... Long story short, I might end up making a similar product in a few weeks. it will probably consist out of 5 digits and if it's up to me (not sure what the client wants) I'd stuff them behind a long picture frame. Something like this but actually mechanical and not just a picture of it:  http://www.notonthehighstreet.com/thedriftingbear/product/personalised-framed-vintage-flip-clock-print So I started googling every hardware piece I needed and it turns out it's a huge pain to find Flip Clock Numbers / Flip Board Numbers... whatever you want to call them. (What's the right name btw?) You can't just buy these things, let alone in a custom size. So the idea is to build them myself. I found this on wikipedia, which gives a clue about the inside: http://en.wikipedia.org/wiki/File:Analog_clock_with_digital_display.png So I'm figuring out what needs to go in it to make this work. (I'll end up making an instructable about it) The numbers themselves are going to be made out of vinyl stickers. You can easily buy those from ebay in about any size if you look for them. The stickers will be put on to plastic boards. But I'm not totally sure what kind I should get. They should be thin and must be able to stand up straight, yet "easy" to fold. I'll probably get them lasercut, but you should be able to cut them by hand as well. Currently I'm thinking about gluing small metal or carbon rods on the back of those letters. Although I'm not sure if that would be strong enough. Would it be enough to file one side of the rods to get a bigger contact surface? (What do you guys think?) I'm planning of putting the half letters in a drum of ABS or PLA. it should be shaped like this:  |--------| I'm thinking about 3D printing this. But no idea how it'll do... One side of the drum will be connected to a small stepper motor (5.625° with 1/64 reduction). I don't have real experience with stepper motors, but this resolution seems more than sufficient. The other side will be connected to a metal or plastic positioner. Each digit might end up with it's own "unit" so I can swap them separately if they'd break. I've got great experience with lasercut plexi, so I might use that because it's more accurate than wood and I might have some lying around. I was first thinking about 1 stepper motor and a set of gears. I decided not to do that in the end because I don't have good experience with making gears and I can never find the right sizes online. Also, it'll make everything way more complex. So each motor will have it's own controller connected to it. Those controllers would have to talk to an ATMega or something. (I'm planning on using an arduino to prototype, but then just swap the chip and make a stand-alone version without usb etc) The ATMega has to be connected to the internet of course to get the current number of likes, so I'd connect it to a raspberry pi via I²C. I'm not familiar with the GPIO pins on the pi so I figured this would be a save and convenient way to handle this. The ATMega is robust, and I love the Arduino bootloader. A sketch is written in no time, but I have no idea how to start writhing this code for the GPIO pins. So why the Raspberry Pi? First off, this thing might end up being wireless, and since a wifi module for the arduino costs as much as a Pi, I figured this would be easier. The plan is to make the pi run python script that could ask the number of likes from the facebook API. Once returned, it'll send +1 or +5 or +10 over I²C. The arduino shifts the numbers to the correct position and replies with the total number it's displaying (3012 for instance). The PI can then recheck if everything is in sync. As for the set up. Since we have Pi, we can put on a LAMP stack (I know, this is overkill, but it wouldn't hurt either). So for initial set-up, we'd connect the counter to ethernet, browse to it on a different computer via "http://counter.local". And we'd be presented with a web interface. You'll be able to set the URL of the page u want to get the likes from, set and reset the number that is displayed on the counter, and the WIFI settings. The WIFI settings can be saved in the wpa_supplicant.conf file and on reboot it'll automatically connect to this network. From now on the whole system is manageable over wifi via a html interface. For debugging I might enable ssh though. So I guess you've got the whole outline now. I'd like to get your feedback on this! And this for the mechanics, electronics, and software side of things!

Living salad, makerbot songs, and noodle!

My first day at Instructables, I found myself sitting on a chair fabricated by the guy next to me, listening to plans for a living salad which would grow through your plate, fertilized by worms below the surface and a stained glass window made of dried fruit, trying to focus on absorbing all the information Vanessa and Noah were dishing out. Just beyond loomed the amazing fabrication facilities, with rows of 3D printers, zillion-axis CNC machines, a stocked electronics room, every kind of adhesive you could dream of, and even a test kitchen! It was a makers dream, Pier 9 had the material and equipment resources to allow us to realize nearly any idea we could dream up, and dream we did. It was immediately clear that the one month my collaborator Kyle (https://www.instructables.com/member/kylemcdonald/) and I had planned to spend there was not enough. Sadly, it was all we had, so we got to work immediately on Noodle, a little robot with the I/O of a machine but the thoughts and feelings of a human. I could go on about the shop at Pier 9, but the thing that really made the experience for me was the people. Hosting 10-12 AIRs at a time, the studio was always full with people building crazy things. One day we'd experiment with Nick's instruments fashioned from rocks, sticks, and water jugs while sampling cocktails from Ben's machine and Rima's cricket ganache, the next day we'd admire Aaron's work on hoodies that zipped around your hands while being serenaded by Andreas' makerbot which seemed to be singing the future. We were all so excited and inspired it wasn't unusual to find half the group there all weekend long or into the wee hours of the night. I won't go so far as to say anyone slept the night there, but...  Not only did we get to hang out in the AIRea, but we also got to know all the others working at Pier 9. This was a building full of people willing to chat about anything from caustics to contests, lend you their skateboard so you could learn how, or demo their latest projects. Vanessa and Noah couldn't have been more supportive and helpful, and it was so inspiring to run into them in the shop on weekends hacking away on crazy things of their own. With so much going on, we sometimes had to work hard to tune it out and stay focused on our Noodle. Luckily, Kyle and I had worked together before and we were able to divide and conquer pretty productively. Kyle handled the fabrication aspects, spec'ing all the hardware and designing and lasercutting then 3D printing the physical enclosure for Noodle. I was heads down on the software trying to hook up our raspberry pi to Amazon Mechanical Turk, speakers, a display, a camera, and an interface. Thankfully, the long hack sessions were broken up by Vanessa coming by to peek at my computer over my shoulder and ask, "what's taking so long? how hard can it possibly be!" ;) I will end this post here and get to work finishing up our instructable before Vanessa hunts us down. If the specifics of our project are a bit cryptic still, all will be revealed with the instructable post (see attached pictures for more mystery). And to all of you considering applying to the AIR program, DO IT! If you are a motivated, curious person with energy and ideas you will have a blast. And the weather is ok, too. Thanks Vanessa, Noah and Instructables!

Open Call: Pier 9 & Market Street Prototyping Festival Keystone Project

MARKET STREET PROTOTYPING FESTIVAL OPEN CALL Autodesk Keystone Project Call Opens: July 11, 2014 Call Closes: September 2, 2014 Shortlist Interviews: September 17-19, 2014 Proposal Selection: October 1, 2014 CALL SUMMARY: The San Francisco Planning Department has partnered with Yerba Buena Center for the Arts (YBCA) to produce the Market Street Prototyping Festival: an innovative, hands-on, publicly sourced approach to creating the next chapter of San Francisco’s public life. The Market Street Prototyping Festival builds upon a five-year, multi-agency effort for a Better Market Street to re-establish San Francisco’s civic spine as a place to stop and spend time, meet friends, people watch, or just stroll and experience the scenery. As a formal piece of the planning process, the Prototyping Festival will commission and exhibit up to 50 design projects that aim to improve lives by improving public spaces. Each of the selected prototype projects will be installed on Market Street for the full duration of the three-day festival, which will take place in April 9-11, 2015. Matched with one of five Festival Districts on Market, selected teams will work directly with community members to shape the direction of their designs. The call for applications for those 50 projects is currently open and will close on September 2nd, 2014. More information on that process can be found on the Market Street Prototyping Festival website. Market Street will be broken out into 5 districts along the corridor: Civic Center, Central Market, Retail, Financial, Embarcadero. Each district, or "Block," will be represented by a Block Captain. Each Captain will mentor 10 selected prototyping teams and will be responsible for developing their own Keystone Project that will serve as the primary focal point for each district. As the Block Captain for the Embarcadero district, Autodesk is seeking proposals from engineers, industrial designers, architects, artists, and interactive designers for a large-scale Keystone Project to serve as a physical, visual and social anchor for the Embarcadero section of the festival. While there is no official theme for the festival itself, the Autodesk Keystone Project should relate to the ethos “Inspire, Design, Create.” Additionally, it should connect to the character of the Pier 9 Workshop where artists, designers and fabricators are empowered to test the limits of existing technology, both digital and mechanical. Special consideration may be given to projects that incorporate the following themes related to place-making and the unique social and spatial conditions of the Embarcadero district: • site specificity: social, cultural, geographic, and civic histories • connecting digital and physical realms • daring experimentation/playful prototyping • edge condition: city + waterfront • wayfinding and transportation networks LOCATION: Over the course of the festival, the city anticipates foot traffic of over 300,000 visitors. The Keystone Project may be installed anywhere within the festival’s Embarcadero district, which starts at the intersection of Market and Spear Street, extending to the traffic island at Embarcadero and Market, possibly including Jimmy Herman Plaza. See the map on the Market Street Prototyping Festival website for more details and note that Autodesks main San Francisco office is located at 1 Market. PRECEDENTS: The following projects are examples of what the application review committee is looking for in terms of scale, tone and available resources. These samples are meant to serve purely as a reference and are not works that will be featured at the festival. - Sukkah City, Various, New York - 21 Balançoires (21 Swings), Daily tous les jours, Montreal - Light Drift, J. Meejin Yoon, Philadelphia                 (Note: Projects for the 2014 Urban Prototyping festival cannot be installed in the bay.) - Digital Empathy, Julianne Swartz, New York LOGISTICS, EXPECTATIONS, AND SUPPORT: The selected project and team will be fully supported by the Pier 9 Workshop!

Reflections on the Pier

Writing this is one of the hardest things to do. Writing this means that my artist-in-residence at Pier 9 has come to an end. What motivates me to keep writing is something that I learned and deeply embraced at the pier. The pier taught me that giving back to the community you're in is priceless and extremely valuable. More on this later. First, I want to tell you a little bit about my journey at the Pier.  During the first quarter of the residency I was overwhelmed by the things I could make at Pier 9. Pier 9 has it all, it's a makers / artist / designer / engineers paradise. So when I got there, I realized that I could make anything, which then made me question why I wanted to make those things and if those things really mattered... What impact would they have on the world, on me, on my surrounding community... This period of questioning was frustrating and hard. While others at the pier were making amazing objects and projects that were getting a lot of press and attention I was just sitting there... thinking as time was quickly passing by. Maybe this was something akin to writer's block. Maybe this was just me being an emotional artist. Maybe this was just me being burned out from a hard year of working at start ups in Silicon Valley. Maybe this was just growing pains (because I was transitioning from writing software to making physical things).  Things got better tho. What really helped get me out of this rut was the community at pier 9, especially Vanessa and Company. The community at Pier 9 is hands down the most valuable asset the pier has. The machines are great, but its really about the people that the pier attracts. Never have I worked in a space where everyone is so excited, helpful, funny, and happy about their work and the community around them. The culture at the pier is what helped me find my path and eventually helped me make a couple fun projects. I could go on and on about how awesome the community is, but I want to give you a couple concrete examples of things that happened to me that helped me grow and morph into who I am today.  Vanessa Sigurdson would sit down with me every so often and ask me how things were going. When I got really stuck on something she would immediate connect me with someone who could help me or show me something that could inspire me or help me get through my block. Thanks Vanessa, I owe you big time.  I asked Noah Weinstein a ton about his shop in Oakland and how he started it. His super valuable knowledge made me feel empowered and able! He is an individual that really follows through with what he says, very admirable! Thanks Noah!   Andy Lee and I would sit around and talk about triangles and math. Andy is an awesome maker and brave individual. He taught me to just try things out and not care too much if they failed. Andy's experiments at the pier made me feel comfortable prototyping ideas and concepts. Not everything has to be a final art piece. Being an artist / engineer is also about exploring and failing! Thanks Andy! Paolo Salvagione connected me with a major museum in SF. Next year I'll be showing a couple pieces there. His work has been an endless source of inspiration for me. The mechanical beauty in his designs inspires me to make every element in my art pieces elegant and beautiful. Paolo you are the man.  Dot Matrix and I went on runs along the Embarcadero to Crissy Field. Dot gave me some great perspective on the projects I was working on and vice versa. These runs helped clear my mind. In addition, looking at the ocean reminded me that the world is bigger than me. Its a great stress relief. Thanks Dot!!! Sitting next to Andreas Bastian was one of the best parts of the residency. Every time I thought what I was doing was hard, I'd just look at this desk and be humbled by the challenges he was taking on. Thank you Andreas, your work ethic is off the charts.  Craig Dorety blew my mind with his LED sculptures. Experiencing one of his pieces was like a DMT trip (from what I've heard :) ). Craig also taught me a ton about the art world and about how to do miter cuts on the water jet! IGES files are the key!! Thanks Craig!  Robb Godshaw taught me how to follow my impulses. If you have an idea brewing inside of you, you MUST make it! You are an awesome individual Robb! Keep killing it!  Observing Anouk Wipprecht taught me about being fearless and tackling challenges with authority. In addition to being an amazing designer, maker, hacker, and person, Anouk really knows how to reach out to her networks and communities for feedback, involvement, and help.  Dr. Woohoo taught me how to connect with people, and empowering others around me. His optimistic & mature perspective and hilarious nature always helped me find my way though all sorts of problems and challenges.  I could go on and on. So many good memories and so many things learned... Side note, I believe that Autodesk's Pier 9 will go down in history as the Xerox Parc of our modern day. So many talented people / things / concepts / ideas / pieces of knowledges come in and out of it, I don't know of any other place in the Bay I'd say is more innovative, cutting edge, open and inviting. Maybe Google X, Maybe Tesla / Space X... MAYBE.... Towards the middle/end of my residency when I was wrapping up projects, and new artists were coming in, I had this deep urge to help the new artists find their way just as the coordinators and other past artists had helped me find mine. Helping the new artists was one of the most satisfying things I did at the pier. I'd like to think my residency at Pier 9 has come full circle, but I think it even goes deeper than just my time at the Pier. I did my first instructable (as in I made someone else's creation) in 2007. Now 7 years laters, I hope that the instructables I have written and will write in the future will inspire young makers to keep making and eventually give back to their community in any way they can!  Thank you Pier 9, Thank you Instructables, Thank you Autodesk, Thank you fellow Artists. I will try to pay you back one day.

Analog and Digital Inputs for Teensy 3.2 MIDI Programming within Arduino

Been having some trouble with programming my custom potentiometers for my midi controller. I have 12 buttons and 6 knobs. I have it wired correctly and have the sanwa arcade buttons working fine. I'm just having a huge problem adding analog code to my digital code. I'm not sure where to go from here, I have tried over 20 different types of analog code and I'm not sure what I'm doing wrong. Just need a basic potentiometer for reading MIDI. I have the first 1-12 digital inputs on my teensy soldered in for my arcade buttons. For the analog potentiometers I have them soldered on inputs 18-23 or (A4 thru A9) on the Teensy 3.2. I am using Arduino software along with the Teensy loader. Any help would be greatly appreciated, thank you. Here is the code I have thus far. I only have the 19 and 23 analog inputs written in this one at the very end, because I removed the others.  ******** /* Buttons to USB MIDI Example    You must select MIDI from the "Tools > USB Type" menu    To view the raw MIDI data on Linux: aseqdump -p "Teensy MIDI"    This example code is in the public domain. */ #include // the MIDI channel number to send messages const int channel = 1; // Create Bounce objects for each button.  The Bounce object // automatically deals with contact chatter or "bounce", and // it makes detecting changes very simple.
