### Learning Redstone

I'm here today to teach you how to have fun with Redstone, now if you don't, you may just jump into a Minecraft sand well and drown. Okay, first thing is first, the BASICS. You may already know that there are what we call 'Logic Gates' in all forms of machines from a computer to a simple on and off switch. We are going to be talking about the main logic gates for now. So let's get started. The NOT Gate: The NOT Gate is what I think is the easiest logic gate to comprehend in Minecraft. It is basically an inverter. It inverts the input. For example, if I were to take an input of Redstone that is on, it would invert it and give an output of Redstone that is off.If it were off, it would be an output of on. This is one of the most used Redstone logic gates. The OR Gate: The OR Gate is also VERY simple to understand, and is also called a Universal Logic Gate, this is because you can use this gate to make any other gate existent. OR basically means 'One input OR the other input  OR both will give us an output'. This is like saying 'Jeff's dog will get a treat if he jumps in the air OR he rolls over, OR does both'. This is also easy to comprehend. (The NOR Gate is the same as the OR Gate except its output is inverted) The AND Gate: The AND Gate reciprocates the OR gate except for one major difference. Instead of 'If one OR the other is on the output is on', it is 'If one AND the other are on the output is on, otherwise it is off'. So what this is saying is that you need to have BOTH inputs on in order to have the output on. This is like saying 'Jeff needs to turn the handle AND push the door to open it'. (The NAND Gate is the same as an AND Gate except its output is inverted, the NAND Gate is also a universal gate) The XOR Gate: The XOR Gate is also very similar to the OR gate but instead of 'One or the other or both', it is 'One or the other'. XOR means 'Exclusive OR', meaning only one of the inputs can be on or else I wont turn on. This is very important when dealing with Redstone calculators or ALUs. It is one of the main functions of a Redstone Adder or Subtractor. (The XNOR Gate is the same as an XOR Gate but its output is inverted) Those are all of the main basic logic gates I'm going to take you through today! These ones are the most important ones to be used and can help people a lot. There are PLENTY more to go through but that would be a bit much documentation for me to handle. If you need any help or need some easy visuals, you can go to StephennJF's YouTube page, or you can also go to bennyscube's YouTube page for help too.

### Sorting Machine

I am wanting to make a sorting machine for my autistic son, so he can learn how to tell different materials from each other & also different colors from each other.  I know that there are a few things that I want in it & also a few things that I am sure that I will need but I need a little assistance on how to go about it. I know that it will need a load sensor for the weight detection, & light sensors for detecting the color (I'm not too sure that is what I'll need), & I am not sure how to make it detect the materials though.   To give a small overview of how I want it to work is that he will place the colored block (he has some that are foam, some are wood, & some plastic ones) or a toy car (die cast) & he will drop them into a hopper that has a conveyor belt that will drop the toy onto a lever that will slide the toy onto a scale w/ a sensor to tell the color (or stripes) on the toy & also it will then be swept to the next station where it will tell the material the toy is made of & then drop it in the proper hopper.  I would also like indicator lights to show where things are going to show him what's going on if he'd like to watch. Can I get some help on this please.

### Computer program learns physics

From Wired:"In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings.Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. ...Condensing rules from raw data has long been considered the province of human intuition, not machine intelligence. It could foreshadow an age in which scientists and programs work as equals to decipher datasets too complex for human analysis."LinkThe software has a long way to come, but apparently it's showing a lot of promise.What do you guys think? If computers can do physics better than humans, does that make human physicists obsolete?

### Suggestions for a great sewing machine??

I'm trying to get back into sewing again and need to get a new machine. I make creatures, stuffies, monsters, and embellish my daughter's clothes. I'd love a machine that can help with needle threading and the horrible bobbin... stuff. I heard about a machine that has some built-in letters - that could be cool. I don't want a really complicated machine though - I had a Husqvarna Rose embroidery machine and the learning curve (for me) was more than I had time for. It was never used. Any advice is appreciated - Thanks!

### Technology Category: Artificial Intelligence/ Machine Learning/ Data Science

I would like to see AI/ Machine Learning/ Data Science be a Subcategory in the Technology Category on Instructables. The field of Data Science/ Machine Learning is on the rise. Machine Learning is being integrated into various products & services we use on a daily basis. Below is the Developer Roles chart from the Stack Overflow Developer Survey 2017; It shows that the field of Data Science & Machine Learning combined accounts for approximately 12% of those surveyed, compared to the combined 1.6% in 2016. A large number of Open Source Machine Learning libraries like TensorFlow, SciKit, etc have been made available to developers across the world. These libraries enable developers & engineers to integrate ML models, Computer Vision, Chat Bots, Speech & Text recognition, etc into their projects. The Google Assistant & Amazon Alexa AI both AI Assistants are now compatible with the Raspberry Pi. Android Things - An OS built for connected embedded systems which can run ML & AI programs is now compatible with Hardware Platforms like the Intel Edison/ Joule & the Raspberry Pi. Platforms such as OpenAI conduct fundamental research & provide free software for training, benchmarking & testing AI. Kaggle - a website for hosting Data Science Competitions has a large collection of high-quality public datasets. There are many other platforms & frameworks like these. With the growing number of resources being made available in these fields, it is only natural that a large number of people will be looking for tutorials & instructions to help them integrate these resources into their projects. Instructables could become the repository of ML/AI based projects. E.g: AI-based Security System, a Line following robot which uses ML algorithms to follow the line, etc. I hope we can have a constructive discussion in the comments as to how we the Instructables Community can make Instructables the best repository for AI/ML projects.

### Machine shop training course.

I am thinking of running machine shop training courses in the UK for those interested in learning how to really use lathes and other big shop equipment. The idea is subject to insurance company permission etc. but I wanted to gauge if there was any potential interest from people here (obviously only those based in the UK, unless you really want to commute) I'd expect costs to be something like 50 GBP per day + materials, and no more than two or three people per session, keeping the ratio of machines to people as 1:1. We'll probably try and do "group projects" as well as bring your own. The idea of group projects is that every ones gets to make more than one of something, to get techniques sorted out, and then we combine everyones work into assemblies - collaboration at its finest.

### Does anybody know of a website for learning how to create remote controlled machines?

I am a part of science olympiad at my school and we are trying to enter into the remote control arm competition. The point of science olympiad is to help students learn about different science fields. Well, the problem is that the only person who knew about remote control machines and electronics had to leave due to personal issues and the sponsoring teacher does not know about electronics, only chemistry and biology. I searched superficially through the internet and I could only find advanced remote control machines and not how to work about the basics such as a simple switch control. I was wondering if anyone knew of more descriptive websites or tutorials for remote control design?

I was interviewed by Youth Radio, an Oakland-based organization that helps underserved young people learn how to make their own media, and David Pescovitz of Boing Boing about starting Instructables and running the business like a scientist. They took video and audio, and did a fantastic job of editing it together with cool music into the embedded video and audio tracks here: From their post, B&BII;: Behind the Scenes of a How-To Machine:Eric is an MIT-educated engineer and avid kite-surfer. He started making his own surfing equipment and then writing about it online. Soon, he picked up a following. Other people wanted to share their own projects and create a Do-It-Yourself community. And so instructables was born. Now, Eric's running a business, but he still thinks like a scientist--isolating variables, making interventions, assessing data, and then starting that cycle again--to grow his enterprise.In the first segment, Wilhelm elaborates on how he started the site and describes how it works. In the second segment, you'll learn about some of Wilhelm's favorite projects on the site.

### Why are some Instructables teaching how to steal?!

I think Instructables is a great site but am concerned at some people posting Instructables that teach stealing. Some tell how to 'cheat' machines you'd normally pay to use (soft drinks dispenser, photocopy machines). Isn't this irresponsible and just plain wrong? Also these machines have to pay their way and if they are found being abused they will likely be made more expensive (or unavailable), from which legitimate honest users suffer. I don't want Instructables to get a bad name. Imagine if some schoolchild or delinquent follows tips how to do this, gets caught and prosecuted, and admits "Oh I was told how on Instructables"... I don't want that kind of publicity for Instructables, just the same as I wouldn't want a friend accused of being an accomplice to crime. This is a great place to learn, and likely we all want to avoid losing our freedoms here and having restrictions imposed. To keep it this way we need to be wise. I think hacks that amount to theft are inappropriate.

### Efficiency of DIY bitcoin miners?

First, I would like to say that I do not know if this is the place for this question, but: I have just heard of bitcoin mining and started to look into it.  I have learned that pretty much the only way it is plausible is through the use of a machine dedicated to mining the bitcoins, not through using gpu's anymore apparently.  But I have seen that these machines are expensive, so naturally I would want to build a DIY one if I started this.  But are these dedicated miners even efficient? And what if they don't have the top of the line components?  I tried to look this up myself but I don't really understand the hash rates of these machines so I don't know what is considered an efficient rate.  And, in my current situation, I don't pay for electricity or internet so now would be an optimal time to do so and maximize profitability.  So, do these dedicated miners work efficiently enough to make it worth while to build/buy one? Especially if I don't pay for electricity or internet?

### Giant Robot Architecture Talk by Greg Lynn in Berkeley

Here is an interesting talk from the Art, Technology, and Culture Colloquium of the Berkeley Center for New Media...Giant Robot ArchitectureGreg Lynn, UCLA & Angewandte, ViennaMonday, Feb 4, 7:30-9:00pm- Note Special Location: Berkeley Art Museum Theater- Enter on Dwight Ave: http://bampfa.berkeley.edu/visit/visitor- Lecture is free and open to the publicAbstractRobots. In my office, my staff keeps asking for more new machines, and every time I get a new machine, I fire two or three people. By extrapolation, in the next few years I will be sitting in an office by myself with a bunch of robots. We have is a very large CNC (computer numerically controlled) cutting machine, a laser cutter, a 3d printer, and soon we will have a robotic articulated arm. All of these things let us do studies of models, which are very important to architects, but what they also let us do is learn machine language. We spend more and more time talking to machines; speaking their language. It is very easy for us to go to any country that has an automobile industry or an aircraft industry and give their machines instructions and do things with these large machines at an architectural scale that is very perfunctory and affordable. The spread of machine language and programming is more significant than the Anglicization of the world. Learning to talk to robots is very important to my field of design.Speaker BioGreg Lynn is a leading pioneer at the intersection of computing, design, and architecture. His architectural designs have been exhibited in both architecture and art museums including the 2000 Venice Biennale of Architecture where he represented the United States in the American Pavilion. His work is in the permanent collections of CCA, SFMoMA, and MoMA and has been exhibited at the Pompidou, Beyeler, Cooper Hewitt, MAK, MoCA, NAI,Carnegie, ICA and Secession museums among others. In addition to his architectural work, his Alessi "Supple"Mocha Cups and his Vitra "Ravioli" Chair are in production and have been inducted into the Museum of Modern Art's Permanent Collection. He received the American Academy of Arts & Letters Architecture Award in 2003. In 2002, he left his position as the Professor of Spatial Conception and Exploration at the ETHZ (Swiss Federal Institute of Technology Zurich) and became an Ordentlicher University Professor at the University of Applied Arts in Vienna.He is studio professor of Architecture at UCLA and the Davenport Visiting Professor at Yale University. Greg Lynn holds degrees in architecture and philosophy and received an Honorary Doctorate degree from the Academy of Fine Arts &Design; in Bratislava. In 2001, Time Magazine named him one of 100 of the most innovative people in the world for the 21st century. In 2005, Forbes Magazine named him one of the ten most influential living architects.http://www.glform.comMore info on the colloquium here.

I need a some help from a programmer/ technical person for my art project (immediately)- Short about the project: The Project is planned for the end exam exhibition at the Gerrit Rietveld Academie, June/ July 2008, but might also be shown at later occasions. The work is an installation with video projections, machines and live insects. A box is located on the top of a pedestal. The box contains crane flies, which will be seen through a small window. The crane fly's movements are intercepted by sensors which translates the movements to commands for a machine. The walls in the room are covered by video projections. By means of wires, the machine can move around in the whole room. Technically what I need is: Through an actometer (insect movement detector) the electric impulses created by the movement of the insects, can be viewed in a software on a computer. What i need to do is to use the graph of movements in the software to send output commands to a machine (made by me, controlled by Remote controlls). I am not sure of how this can be done in the best way possible, but I have some suggestions which I can explain more precisely later on. I am looking for someone who have knowledge in terms of programming, and could be able to come up with a good solution, as well as maybe collaborating/ helping me out with my project. Please let me know if you are interested, know someone or know where I should go to meet the right people here in amsterdam. All answers are appreciated! Thank you in advance Andrea

### How do I set up a mobile wifi router (LAN), and a wifi windows machine? Answered

We are a collective of dancers and bicyclists that organize huge bicycle rallies up and down the west coast. There are dozens of bicycle sound systems on these rides, and we seek to send an airplay audio signal to everyone's smartphone with wifi. The software of choice is Airfoil. http://rogueamoeba.com/airfoil/  For it to send audio, it needs to be installed on a windows or mac computer (not cell phone or tablet). Smart phones can then receive the audio signal. I need help designing a road worthy wifi router and windows machine to be the moving hub of this wifi broadcasting party. Extra points for durability, signal strength and thrift. Please be detailed, because I am only vaguely knowledgeable of wifi, and I'm not that bright. Please note that I am well versed with other options for sending an audio signal. I have reasons for being this specific. Without your help, I would acquire a used netbook with a solid state drive running windows (maybe about \$200), grab a wifi router (I have a few older ones lying around) run it all on an inverter and give it a go. Because I am a mac guy, I don't know how to do anything, like how to set up a local area network.... (I usually jam in a cable from a high-speed modem).... we are not doing that on a bicycle, so I'm a bit fuzzy on that part. I am well versed with power supplies, and willing for the range to be less than ideal at first... (that can be improved later) I am just looking to get a trial of this system up and running. I am most appreciative of your help, and I plan on writing a full article on what I've learned, if successful~ Thanks!!! Tor PS, Photo not of me, but these people are obviously awesome, and will love what we are doing.

### How to: get started

Hi everyone! I'm kinda new here, but I like the site a lot. I've been thinking some time about starting to build things, learning a bit of programming and so on and so forth. And then I found this site. Now I'm planning on forming a hobbyist club with some of my friends (we are 16-17 years old). The problem is, I don't know with wich projects I should begin... We don't have a CNC machine or 3D printer. All suggestions are very welcome, from building a boat to a cannon to some toys to some costumes etc. If possible, please post the instructable here. Suggestions are also welcome! Thanks in advance! :p

### Verifying Age Using Face Recognition?

Magazine photos fool biometric age verifier in Japan. In their never ending quest to automate every aspect of human life Japan has recently installed cigarette vending machines that will scan your face to verify your age before giving you a smoke. Kids realizing that all the robot wants is some wrinkles have learned that all they need to do is hold up a magazine image of some geezer and then they can puff away. It makes me happy to see that no matter how "advanced" technology becomes, there's often an easy overlooked loophole. Let's hope that trend continues. _BGvia: boingboing.net

### Embroidery Text Ideas -- Get a Free Custom Shirt!

So.... I'm at home for winter break and my mother has acquired this newfangled sewing machine that can do CNC embroidery. I've taught myself how to use it (and now teaching my mom :P) and I want to do an instructable.Tell me -- what text would you like to see on a T-shirt beyond the word instructables (I have several patches already :P)? Add it to my list below and I'll pick out a few ;)If the house is quiet enough (family of 6 et. al.) - I can probably take video of the process (from how to make a bobbin --> set the top thread --> fabric stabilizers --> needle selection etc.) and post it. I know it is a bit specialized to the machine -- but from what I found at the quilt shop... There's a lot of people that own the machine and don't know how to use it...Running List#Stercus fit (Translated from Latin: Shit Happens) <-- my girlfriend wants this :D#Jag Lik Bananerna (From Swedish: I like Bananas)#I Do My Own instructables#This T-Shirt Is Now VoidIf I like your post -- I'll make a second T-shirt for you. So post your T size with your submission. You can eMail me if you don't want to post your T size ;) Be aware - I'm learning through use. So there might be minor defects. Post soon because I won't be home very long.

### EITHER: How to make 'continuous heart pulse monitor'? OR: how to capture ECG from chest strap?

Greetings, What I am interested in is a ‘continuous heart pulse monitor’ so that I can plug that into (possibly) an arduino to drive a EECP machine. EECP machines run around \$30k. So I’ll have to jigger up one myself. Usually I program in HotBasic. I am now learning ‘C’ programming language, via “Arduino in action” eBook, and sparkfun arduino Uno kit. I could sure use some help, like: Should I just buy a ‘chest strap heart rate monitor’, (Polar, or Motorola, or what)? Are there any units out there that can plug directly into a usb? Or do I need to get into wireless or bluetooth? Is a chest strap monitor more accurate than a finger or ear monitor. Should I be connecting to a laptop vs arduino? As you can see I am just beginning. Any help you can give me will surely be appreciated. Thanks for your help...Vernon

### Is there anyone out there who can teach me to circuit bend, create/re-purpose circuitry, use Arduino?

Recently, I've become fascinated with Instructables involving re-purposing gadgets, gizmos, and gears. I want to learn some basics before I start dismantling my old cell phone or cd player, but I don't know anyone I can ask. And even if I did know someone, I'm not sure I would know WHAT to ask. I'm at the beginning of a machine and motherboard addiction, I can feel it. Do you know any good dealers? _Science on the Side_

### How to Upholster a Box

In my quest for weeding out my less than professional looking projects, I am in need to learning a new skill.Does anyone have recommendations for a resource on how to upholster a box? Key points including the box material is a thin plywood which probably won't hold up to staples (thicker woods are heavier and I have a weight restriction for this project: lighter = better). My material will be a marine vinyl (for weather protection) which does have some stretch to it - I'm also going to put a thin foam backer for that extra supple feeling.Recommendations for obscure compound curves would be nice too.I'm armed with a sewing machine, limited sewing skills, bandages and some scrap material. <-- that on top of the typical measuring instruments.

### Is it possible to DIY an ipod car adapter. (one of the ones that plays through the cars radio)

If you're not sure what i mean, It takes the ipods audio signal and broadcasts on a radio frequency that is then picked up by the car and played through the cars sound system. I really would like one but dont want to pay \$50 Some note: -I have a limited but understanding knowledge of electronics and can learn new concepts easily -It would be best if this could be made from parts from around the house as i tend to have a limited supply to electronic components (i do have access to old machines like printers and an old computer tower and then a bunch more that i can scrap for parts) Also, I could probably find an old radio somewhere as im sure that would help

### Instructables Goes Indoor Skydiving

The Instructables team has been going strong for a while now - some of us have even been with the company for over two years! Eric took Rachel, Eric N and me to iFly, an indoor skydiving facility, as an anniversary gift. Flying is awesome, and now we want to build an indoor machine of our own! I'm going to publish all of my Instructables in flight from now on.Here's video of the first flight we did where we were just learning how to stabilize ourselves.Here's video of the second flight we did where the instructor took us up and down, spun us around, and let us move around a bit on our own.**music NOT from noahw**

### Magnetic actuators - anyone here ever made one?

Magnetostrictive alloys like Galfenol are not only quite cheap but also quite possible to produce and machine at home. As it seems that right now I can't finnish anything without being stopped by something else that got my attention I am a bit stuch on all ends now LOL Anyway, I still have a few kg of rare elements like Gallium, Bismuth, Antimony and such that I misused for my testing of home made ferrites. So apart from making some fancy metals that melt at very low temperatures I thought a much better test usage would be to make something that for once has some real world use :) If you look up some of the research papers for Galfenol use or magnetostrictive materials in general you soon learn two things: a) You need a degree or have studied something related to fully understand the technical stuff behind it. b) Finding something that would give you enough info to make something that works as planned is next to impossible. I don't mind wasting some time on melting steel, machining some samples and do some testing but of course this takes a lot of time... So I was wondering if anyone here already experimented with magnetostrictive materials and their possible uses? Apart from micro actuators for minature things I don't have I was thinking of generator use. A lot of things produce wanted and unwanted vibrations, magnetostrictive alloys are capable of transforming them into electrical energy by simply using a coil around the material. For example the recoil of your favourite hunting rifle could in theory charge your dot sight or laser sight/flashlight. Or the otherwise useless vibrations of big machines or rock tumblers can be turned into something to charge your phone. Not to mention impact sensors or flat surface loudspeakers....
