Best Material to Use in Toy Manufacturing with 3D Printer

I don't really have any background in manufacturing toys but a guy in my warehouse is trying to create some prototypes on the side for a line of figures. He compares them to these Monsters in My Pocket toys: http://i1.wp.com/pixelvulture.com/wp-content/uploads/2014/11/90s-Kid-Monster-in-my-Pocket.jpg And these Muscle Men: http://i.ytimg.com/vi/6SfDGf7b4_o/maxresdefault.jpg They look like they're made of rubber. I was wondering what material you'd suggest for creating durable prototypes of similarly sized and shaped figurines?

Guitar Pedal Prototypes

Don't get me wrong, I love acoustic guitars... But I love a good crazily distorted guitar that almost sounds like a synth. Rage against the machine's guitarist Tom Morello epitomizes that wild sound for me. Most good bands have an instantly recognizable sound and one of the ways a guitarist can distinguish zer self is to use a unique set of pedals. Now you could go buy a set and find just the right setup for your taste... or you can build your own. Best part is, there's no soldering involved:Bevis Boardvia:Make

Obtaining non commercially available parts?

For a lot of projects I find myself needing parts that can't really be bought in a store. My latest project requires transparent conductive ink (http://www.conductivecompounds.com/sitemap/clear-conductive-inks.html). Has anyone had success obtaining parts directly from companies like this? I was thinking emailing the sales rep, saying I'm working on a prototype, and requesting a sample. Do you think that would work? Could someone point me toward a template for an email that would sound "professional"? Also what type of payment do you think they would expect, would just a credit card number be fine? Thank you.

New inventor seeks industrial designers......

Hello, I am inventing a new golfing product.  I have a working prototype and I'm filing my patent now.  But I needs some help with improving the design.  I'm not a professional designer but I have some mockups in Sketchup.  I am looking for someone with experience designing commercial products in solid works.   The product is going to be made out of plastic and it's has a few moving parts.  For the most part it is very simple but I want to make it into a higher quality product.  If your are interested in working for me as a consultant, let me know and I will send you an NDA to sign. Thanks, Joe

Looking for Eagle file for standard breadboard power.

Hello;   I am trying to find an Cadsoft Eagle .brd file. I want to plug boards into a standard breadboard, for power. I want to plug onto the thin side. It seems to be a metric measurement, even though it is 0.1" hole spacing. Or if someone has the spacing info for the pins? I measured 4mm on centre, then 40mm to 51mm for the far row. So it would be on the left or right of the breadboard. I always round ground at the outside, and 5v in the middle. So swapping ends will work. Thanks, and I will keep looking Mick M

Thoughts on a prototyping device

Hey I'm a college student trying to create a specialty extruder to aid in prototyping, possibly to be used along side a 3D printer.  Attached is a CAD mockup but we're in the process of building this.  The applcations are fairly broad at the moment and if you think of a cool way to use long pieces of plastic for modelling, crafts, art, whatever, please let me know. This is my kickstarter and I'm trying to get any feedback you have, thanks! https://www.kickstarter.com/projects...?ref=discovery

Folding Bike Wheel Invented

Traveling with bikes can made easier with couplings and taking it apart, but the wheel has always been a solid item that has to be worked around. This might not be true in the future with this new folding wheel that is made up of six segments.This design by Duncan Fitzsimmons is being looked at by major manufacturers, or so he says, but no matter what it will take a while to come to market and likely cost more than all of my bikes combined. I can only hope that these eventually do some out and the economy of scale makes them only mildly ridiculous in price. link

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! We look forward to having you join our creative community of Artists in Residence, other Creative Projects Teams, and the folks who make Instructables.com go. We provide ample opportunities to collaborate with other designers and makers, to receive training on any of the machines in our workshop, gain software support for all Autodesk products (including free software licenses), and call upon the expertise of our fantastic Shop Staff. We can supply a modest office workspace and 24-hour access to the workshop. All basic workshop supplies will be covered, including hardware, sheet goods, finishes, and prototyping materials. Additional funding will be provided at an amount to be determined. We expect to support an innovative and inspiring project that reflects the use of our world-class facilities, at a scale similar to the precedents listed. For more information on the amenities available at Pier 9, see the Pier 9 Overview and Machine Catalog Instructables. Your project will also receive support from Autodesk’s public relations team, marketing team, video and photo documentation team, software specialists, and workshop fabrication specialists. There will be an expectation that you will work collaboratively with all of these groups to share the progress and product of your work. Finally, we have an Advisory Committee representing expertise in areas of landscape architecture, sustainability, and digital fabrication that can be called upon for consultation and critical feedback at particular points in the project timeline. The selected artist or team will be expected to formally share their progress throughout the development and fabrication process with the creative community at Pier 9 and beyond. This includes: • posting Instructables related to the making of the project • 2 presentations to the Advisory Committee for feedback • 1 lunchtime presentation to the full Pier 9 community, near project completion TIMELINE: July 11, 2014 —RFP Release July 22, 2014 —12pm lunchtime RFP Info Session at Pier 9 September 2, 2014 —Proposals Due September 17-19, 2014 — Semifinalist interviews October 1, 2014 —Keystone project announced October - December, 2014 — periodic consultations with members of Advisory Board Early December, 2014 — Presentation and critique with the Advisory Board Early February, 2015 — Follow-up presentation and critique with the Advisory Board 2 weeks before festival —Dress rehearsal (deadline for full assembly and functionality) April 9-11, 2015 —Installation and three-day festival presentation APPLICATION REQUIREMENTS: - 1 page statement regarding the concept, siting, and fabrication strategy for your proposal - Up to 5 photos/videos of mock-ups or prior work - CV including exhibition history (if applicable) - Proposed budget outline (Please include direct costs, materials, artist fees, contractors, and any additional project contributors or contractors) - Draft project calendar including proposed dates for prototyping workflow, workshop production time, completion time(s), and out-of-town dates (if applicable) - List of anticipated machines and materials needed ABOUT PIER 9: Autodesk’s Pier 9 workshop is a world-class fabrication facility on the San Francisco Bay. The Artist in Residence (AiR) program gives artists, designers and Instructables authors a chance to work with us in our lab and workshops to explore, create, and document innovative projects with our tools and resources and share them with the DIY community. AiRs are invited to come for a period of several weeks to several months, during which they will work on projects that are shared across the Autodesk Studio Communities. The primary goals of the residency program are to produce top-level inspirational content and to connect innovative and creative individuals with our unique set of tools and resources.

New Prototype Knex Guns

Hello fellow knexers!   Today I bring what I've been working on for the last couple of weeks ( and another picture of Zip3 ). I think some of these guns are post worthy and some aren't, so instead of previewing them all separately I've made this forum topic to help me decide what guns you'd like me to work more with, post, or just disappear. So I added the video to show all the features of the guns and also to help bridge the gap I'll also say a little about each of them in this description.       Project Eject. A handgun that eject shells. It shoots blue rods that have spacer shells on them and it increases the guns efficiency and range.      Project Break Action, Break action knex gun with shell. It can shoot pretty much anything including oddammo, with really good range.     Project Precision an assault rifle that bridges the gap between war guns and models. The gun is capable of holding a lot of elastic while shooting well indoors and outdoors. Also has slightly better accuracy due to the long barrel that I lined with micro knex to make it thinner, but not restraining.           Project Micro, a knex gun that uses Micro knex to the fullest, mainly to make the gun four layers thick. Micro knex have similar thickness to a blue spacer, so about half a classic knex piece thickness. I feel that micro knex can push knex guns further and in a more innovative direction, so building this gun was mainly to show that it was possible and a decent idea. The one thing I learned though was that micro knex are a little thicker than the blue spacer so I'll use more micro knex to fill the gun next time.                       So that's what I created over the last few days. I'd like to hear what you knex gun gurus have to say about it and if I've created anything your interested in.   Thanks for looking! JonnyBGood

Lessons Learned/Process Documentation Feature

I have found that, in many new projects, there is a certain amount of planning and a whole lot more trial and error (as expected). As such, the second time I make a project may be drastically different based on the lessons learned from the first. When I think about how I want to present the Instructable, there is always a struggle to capture all the failed attempts without cluttering up the "go do this and it will most likely work" version. Perhaps it depends on the project. Sometimes, I want to just see the steps that work. Sometimes, it would be nice to hear every detail on what didn't work along the way and why the creator decided to do certain things and how their creative process flowed. An idea would be to have some sort of collapsible section of each step that contains all the lessons learned. For example, if you're sewing button holes for the first time in your life, you will probably want to practice a few times. You could capture all the "unused" attempts in the "lessons learned" section of the "Sewing Button Holes" step without cluttering up the satisfactory attempt that you end up going with. This may not be such a useful feature for smaller, simpler Ibles, but could greatly enhance more complex Ibles that involve fairly experimental processes. Maybe you've never used a miter saw before, so you research it a bunch and read all the Ibles on it and look through the forums. You could link all your research within the Lessons Learned and take everyone through your experiences and trials without bogging down your Ible step with too many photos and thoughts. On a larger level than cleaning up Ibles, this could possible enhance the learning opportunity in every Ible, bringing emphasis to processes instead of end products. Maybe you could even tag the Lessons Learned sections and make them searchable as their own entities. Maybe you just want to create an entire Ible on each process you used and link it in the step. This could go in many directions... Thoughts? Ideas? Post links to Ibles that might be able to benefit from something like this?

Make HID (human interface design) beautiful

There are few ubiquitous household items as ugly in form and function as a computer keyboard. They're everywhere. They're an inefficient and archaic visual distraction, barely suited to stamp ink on dead trees, as they were originally designed to do. Computer components need to be elegant, form well married to specific functionality needs, if computers are to fade into the background of life and thus best support it -  and that is nigh impossible with the keyboard hanging out. I'm a hci software guy. I spent almost three years writing a library of code to enable a new generation of input devices… beautiful, simple  and efficient… closer to playing a musical instrument than typing on a typewriter. I need designs for a piece or two of hardware that shows off how beautiful and/or hidden a computer input device can be when you completely minimize its form… If you are an industrial designer or a mid level maker or even a just a for the fun of it 2d or 3d CAD nerd, allowing for the device functionality will be a trivial concern, with 90% of your attention paid to the form of the device… and that's what I'm looking for… a beautiful replacement for the horrible and outdated keyboard and mouse that shows off the features of the software and blends in to people's lives. The designs will be 5-key and 10-key. The electronics area to allow for will be pretty simple -  probably just an HID chip - as tiny as possible - with ports to wire to buttons, etc -  a power source, wireless connector (preferably low power bluetooth), and wires to connect the chip to everything it needs to connect to. While the designs can be created as completely conceptual, we would prefer to be able to physically prototype them using something like 3d printing, laser cutting or other maker accessible options and electronics components that would also be maker accessible. Preferably, the file format will be solidworks compatible. For now, this is an unpaid gig, with the compensation mainly being in the form of some really sweet portfolio designs, hope for a better HID tomorrow, and maybe a makey makey type gift for those times when nothing but a banana piano will do. We do have investor meetings lined up and will credit any prototype designs used to show off the software during those, as well. If we decide to sell the software in various configurations packaged with hardware variations, and everyone feels like a good time was had by all in this trial run, then we can talk about a production partnership. If that were to be a possibility, industrial design related experience or strong enough to heavily research it type interest - sourcing, packaging, etc. - would be a big bonus. (As a note, while the  HCI is all key input based now, there will later be support for things like 3d tracking options - So, the project could get even more exciting on the HID side.) __________________________________________________ If you are interested in learning more, please use the PM system provided through Instructables as first contact. Further contact info will be provided should the initial contacts merit it. Thanks!

Which cell & how many do I need??

I'm new to this whole electrical engineering thing. Thx to instructables, I got a crash course in LEDs & wiring them up. I need to make a prototype LED array. How do I determine the right size & qty of cells (9v, AA, etc.) needed to run an array for a decent amount of time for an end consumer? What's the equation for figuring this out? Will the Ohm's Law equation (which I'm new to) work for me here? Anyone's help would be greatly appreciated!

Quick-vite idea

*UPDATE 2-15-11* If you are good with cell phone apps and website building and you would like to use my idea please message me. If you do make this all I ask for is a very small cut of the profit, but I really doubt anyone would want to make this anyway. Well, if you do just send me a private message and we can talk about it. Keep in mind you still may NOT TAKE MY IDEA UNLES I LET YOU! IT IS STILL COPYRIGHTED BY ME! Hey everyone, I just wanted to share my idea for a possible website I will be making in the future. I got the idea recently when my mom wanted to invite people over to the superbowl and sent out the emails that day. Many people didnt respont because, lets face it, many people dont check their email more than once a day. My idea would be a website based service that you could sign up for for free or become a member for a monthly fee. How it would work is you could type up your message and then send it to a pre-saved group of all the recipients phone numbers, and from there numbers could be added or removed. The site would then send a text to all of the recipients with instructions on how to respond. It would be something like "I'm having a b-day party at my house. 3:00-6:00 at 52 blah blah road. 'reply the number of people followed by y for yes, n for no, or m for maybe. ex. 3y 2n' " Then the results would be replied back to the website where it would compile a list of who and how many could and could not go to the event. Since sending the texts would cost some money it would have to be made up by advertising space as well as limiting the amount of invites allowed to be sent by the free users. Members benefits could include increased invites per month, more recipient groups allowed to be made, and a feature where you could text your website number from your cell phone and it would update you with how many people could and could not go. Since I'm only 16, I would not know how to create this site or be able to spread the word very well, so I would just like feedback on the idea for now. Please tell me what you think about the idea, and if you think its stupid be honest and tell me. Thanks :) And if you take my idea and start making money off of it, I will press charges. I emailed this to myself to sort of "copyright" it and this forum topic will not be edited ever so this will prove it's my idea as well. So please don't steal my idea.

Hello Everybody,  I am Ayush from India.  I am Building a Mini MIT Cheetah Robot Just Similar as the Big one.  Will Fewer Functions due to Size. I will be using a Raspberry Pi 3 or Zero as a Motherboard and Micro Servos for Leg Motion. I have Studied the Very most Videos of MIT Cheetah Robot and i am very much Inspired ! But Due to Lack of a Team and Financial Back Support ,  i am lacking in building it... I will 3D Print Out most of the Parts and Just Before the Final protoType I will Offer Every Hacker / Programmer/ Developer / Student / Enthusiast to Bring his/ Her own Cheetah to Life! This will be a Very Long Development Proccess as we will have to add most of the Features! Facial Detection, Push Sensors, Touch Sensors, Motion Sensors, Gyro , Accelerometer, Ultra sound Sensor. and We will make some Cool Algorithms too!  The Plus Point will be that Until i come to my Final Prototype i will stop using the Modules but will make an Complete Pcb!  Therefore The Size will Reduce! My Design Planing for now is length 15cm - 25cm But will try to make it more smaller! All I Need is a Team and Financial Support! I Have Attached my Very Basic Start Prototype Design! :) Get Involved or Support by   Contacting me Through: LINE App ( Mobile) - My User ID - 'ayushtech' E-Mail - hobbyists.stop@gmail.com Thank You, Ayush Always Love the Instructables Community!

Help (advice) with building a braiding machine?

I've been working with braiding plastic shopping bag strips into rope, and by hand it's a slow and tedious process.  I know that braiding machines have been around for ages, so the patent on many of them has to have elapsed.  I've Google'd and Bing'd and Yahoo'd my heart out looking for how to build a simple one to no avail.  The only thing that comes back is Chinese sellers of a commercial braiding machine. All I want is something that I can build, a hand crank mechanical kind, that can braid 7-10 strands into a larger rope. It doesn't even have to go fast, in fact I'm fine with it being slow. Can anyone provide plans for one? UPDATE: Ok so I think I have plans, but now I could use some advice with how to go about fabricating the sprockets.  One idea is to purchase a premade sprocket and modify it, then use it as a master for a mold to create more.  I was thinking of either doing the whole dissolving styrofoam with Acetone then pouring the plastic in the mold thing, or possibly adapt the Oogoo instructable.  Thoughts?? Update 2:  My latest brainstorm leaves me thinking that I could use a bicycle sprocket (gear) as a master and then make a mold from it, then make duplicates from the mold.  Thoughts???

Knex double shot prototype

Here we have a slightly angled pin knex gun. The pin is slightly angled down, making the pin come in the magazine well angled, hitting two bullets instead of one. It uses an internal flexy bullet pusher instead of the external ones. It shoots two bullets 30 feet using two bands. It has a yellow rod magazine that isn't removable. It also uses a unique trigger system. Its comfortable, light weight and is very fun to use. No sights, its just a prototype.

Design and development in the New World

From the MAKE blog, I found an outstanding article in The Economist on product development in the age of rapid prototyping. In their usual fashion, The Economist gets into the nuts and bolts of how a pair of entrepreneurs used rapid prototyping and Kickstarter to create a real product from their initial ideas. It's a great case study for DIY-ers who think they have something marketable, to show how they could make that happen.

Determining the cost of building a prototype?

Hi there, I am inexperienced in engineering and building things in general, but I am trying to start a tech company anyway. I am currently in the process of determining the budget cost of building a prototype for various designs of ideas. So I am wondering if you can tell me how much commonly used tools and materials of a DIY mechanical/electrical engineering project might cost. If you don't know because estimates can vary, then tell me from your personal experience how much your list of tools and materials costed you on various projects that you've done. Thank you!

Prototype Model Time Machine Mk.43 - With WiFi Retrieval Facility

After constructing several incarnations of model Time Contraption and fed up to the back teeth with the inability to get back my previous prototypes, I have decided to implement a remote 'WiFi Retrieval System' onboard my next model venture. Plans to follow, but here are some of the parts I have assembled so far.

KAGP1- Knex Air Gun Prototype 1 - pictures!

My Break is still not over but this is somthing i have been working on 3 people thought i shouldn't do this, or that is was imposable. I'm not nameing any names... But it works, needs a little tweeking with the shell (still a little breakable from recoil.) i took off the barrel due to it breaking (though will get that fixed by prototype 3 hopefully (or 2 if i dont need a 3)) last picture in this is the best.

Prototype PCB Giveaway!

I'm giving away my prototype PCBs that I did not use. Those are fully functional, factory made PCBs. There are prototype version of Aurora 9x18, Aurora 18x18, Aurora 48 and more! Most of them are the same as the final version, or only slightly different, like using a different switch. The qualification is simple – give me/my site a mention and a link on your web site, or if you have made any of my designs, put up a project at instructables (with pictures or/and video). Let me know what you did by either leaving a comment here or email, and I will send you a PCB. (Free shipping within USA only – sorry, international shipping will cost $5.) Please note: Twitter and FaceBook posts are not eligible. Please go to www.theLEDart.com for details!

Gripper toy/Prosthetic Prototype

Well its a simple cycle brake (side pull single pivot,brake pads removed) inserted in a glove that can be used to grab objects. The initial idea was to build on it further and have the brake lever fitted under the armpit such that when the arm is moved towards the body the lever gets pulled and the grip tightens to grab objects for persons who might be missing part of the hand from below the elbow. However didn't get any further for various reasons, would be very happy if anyone would find it useful.

Non-stop Train Prototype

A train that doesn't ever stop or slow down? Sounds ridiculous (ly efficient). This design is a pretty interesting take on the concept, though liability issues and real-world feasibility will probably keep this from ever making it past the drawing board.Link

Can you make a super small waterproof prototype mp3 player?

I am looking for someone to build a prototype mp3 player that would have the following specifications.  - circular housing and no larger than a U.S. nickel in diameter. - top of the housing would have an insertion for a 1/8 headphone jack. - the height could about 1/4 inch to a 1/2 if need be.  (the smaller the better) - the housing must be waterproof. - the player will autoplay one song when headphone is inserted. Please feel free to contact me here: jacobaa7@gmail.com Thanks, Jimmy

Prototype This premiers tonight

Prototype This premiers tonight on the Discovery Chanel. It stars Zoz, a good friend of mine from MIT. Here's what Zoz has to say about the premier:Dear lords of the realm,Please join me in advertisement-laden spirit this Wednesday for a thrilling three hours of television tomfoolery:8pm: Discovery Channel - season premiere of "Time Warp" produced by crop circle nemesis and doctor of weirdness John Tindall and co-hosted by Robots alum and all-around superhero Jeff Lieberman; followed by:9pm: Network Presidential debate - mix red food colouring with corn syrup and smear it on the screen so that all participants look like the blood-soaked zombies they are; wipe it off in time for:10pm: Discovery Channel - season premiere of "Prototype This" co-hosted by yours truly! That's right, the Apocalypse Now of television - the series that wouldn't die, that took longer than most Master's theses to make, is finally going to see the light of day!Representative websites here:http://dsc.discovery.com/tv/prototype-this/prototype-this.htmlhttp://blog.wired.com/geekdad/2008/10/preview-discove.htmlhttp://news.cnet.com/8301-13772_3-10016485-52.htmlTo anyone who got this shameless plug twice - take it as a compliment because I didn't want to miss anyone so this one is going only to important individuals, not lists! But still tell all your friends to watch so we can get good ratings and get picked up for more seasons so I don't have to find a real job!It's been a long and circuitous path from idea to actual show. In one of the first ideas, Squid Labs was going to prototype various ideas in a reality-TV-like show. To see how it's evolved, check out a couple of the casting reels we filmed starring Tim, Christy, Corwin, and me:MITERS Tour with TimSquid Labs tour with Christy, Corwin, and EricI've got Zoz's casting reel too, and I'll share that shortly.

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!

Hypnotizing 5 Axis CNC high speed car prototyping

Well, i just spent 5 minutes of my life watching a 5 axis CNC machine milling a prototype car out of some foam.I recommend you do the same.Right now.The Machine starts off with a massive block made from some rough shapes of foam. It then proceeds to rough it off into layers, it then adds a more defined smooth layer.To top it off, it then coats the entire thing in a epoxy layer.The entire process is both entertaining, and hypnotic.Via Makezine
