Prototyping service

 Does anyone know of a good prototyping service that is fairly fast, very reliable and has good ethics? This would be a fairly simple job, using leather, paper/cloth and plastic (not electromechanical or gizmoid). Thanks so much!

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

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

ZipDart prototyping help

OK, had an idea and went with it for my ZipDart V.2. Unfortunately, currently having a bit of a brain fart of how to put a ratchet mech in. I've tried 7 attempts, 3 have even actuated and of those three none were responsive enough to be at all deserving of the ZipDart name. There is a google photo album linked below of the mech area and the gun on a whole. Feel free to comment either there or here with any ideas or insight. The mech can be complicated, just so long as it takes less than a half an inch of actuation rod travel to actuate and is fairly strong. Thanks for any help--if anyone has any questions or wants any more pictures, just ask. Photo album

help with patent and prototype

I have been working on an invention/idea for the past year now. I can make a prototype if I really wanted to, if i did it would look like crap, and no one would buy it. Plus, I was told you do not need a proto type to sell an idea. It's a simple invention that you can use small plastic parts, and can be used in everyhouse hold. I have went to places like invent help and others, but no real help. They just want a lot of money to market it for you, and help you get a patent. I have no patent because, I have about 6 different models and don't really know which one is best for marketing, selling, things like that. I don't really know anyting about computers and the internet. I paid a lawyer to look up my ideas/inventions and so far there is nothing out there that is close? Looking for help or different ideas to market and patent my ideas?? any info would help, a lot of web pages for help costs thousands of dollars, which I do not have. I am a Plumber by trade from chicago, and I think it should be in every bathroom,I just don't know where to start. Email daaabears@yahoo.com Thanks nick go bears!!

Oodassault 4 Prototype

Well, here's my first attempt at making my V4. It's packed with features but unfortunately it isn't reliable yet so DON'T BUILD IT! I'm probably going to end up having to totally modify it to work so I wanted to get a picture before I ended up destroying it without hopes of getting it to work. Anywho, I don't care for block pistols but after giving it a shot, it's much easier to incorporate things like a pinlock this way. I'll start listing off the features because I don't want my entire picture to be comprised of yellow boxes. Starting at back working to the front: 1. Uses a new pin concept that I've been working with. There's a red connector connected to the pin, and then the yellows are connected as show to absorb the force. In theory, this should mean that because the force isn't transferred to the connection of the pin and the band holder, it shouldn't require any sort of other force suppressors to keep the pin in. However, it does make a loud clap so I'm probably going to try adding rubber bands around the connectors (but not around the pin) to quiet it. 2. I finally added a pin lock. I'm bleh on it though as it requires a broken orange in the barrel (I just have these pieces "naturally' so I figured most K'nexers would) and a band to ensure it works, but it works nonetheless and it adds almost no friction from the way it's on. 3. I stole KSC's idea for wheels. I'm not sure how much it'll help but I figured, eh, it doesn't hurt. 4. It uses the bullpup trigger idea from my PDR so that I can have a more compact weapon with good power. 5. The handle is from my new UMP and was added to give a more comfortable angle. It also is three layers with no white rods needed. It's decent as far as comfort goes. 6. Finally, it has a tilting mag that's right in front of the handle, so it's easy to access. The problem is I need to make a better pusher and figure out a lock for the new pusher. I think the barrel is part of it because I went back to the old blue rod style. The gun isn't reliable at all. 7. Oh yeah, almost forgot to mention that I'm experimenting with adjustable sights. I didn't make adjustable sights for this gun, per se, but rather I added multiple folding sights that are at the same height, taller than the front sight. This means that the closer the rear sight you use, the more of an angle the gun has. I doubt this'll be useful at all but there was room so I just threw them in there much like the wheels. And that's that. The feel of the weapon is pretty nice. It's balanced. But yeah, that's all I've got to say.

Finding a builder to test a prototype

I am working on an item, and it requires a small bit of dimensional lumber, ply, and screws. I am trying to make the plans as specific as I can, but having worked in the engineering field as a draftsman many years ago, I know that mistakes can and do get made. So, I am wondering how I would go about finding someone to test build (without fooling with the wiring and such for the electrical components) my plans to find any errors or oversights, inaccurate or unclear directions, and the like. How would I go about doing that? Is there even a forum on Instructables for people to be test-builders? That would be a great thing if there were.

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.

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

help creating a biosensor prototype

I will attempt to be as concise as possible. That said, please bare with me if things are explained as well as they need to be, I am very new to this. Determined, but still a novice. I am conducting research as part of an effort to create a wearable prototype. Essentially, I need to combine a ppg heart rate monitor with a infrared thermometer (to measure skin temperature) and to have both devices maintain bluetooth capability. Any input in regards to this would be amazing.  More specifically, I am wondering if there are any DIY ppg heart rate monitor and/or infrared thermometer starter kits? Or resources that will assist with building these elements, aside from tutorials. I ask because it is a challenge to uncover all of the nuance and intricacies with electrical engineering and design without having a sufficient background.  For instance, it is clearly possible to add a bluetooth component to a heart rate monitor, but I am unsure if the two components (ppg hrm and infrared therm) must "talk" to each other while maintaining a bluetooth connection to a website or some other device.  If this is all as "simple" as building these devices separately and adding a bluetooth component to each of them, it would be greatly appreciated if you can provide a specific link to easy sources to obtain the components. I think I can follow along the tutorials, though there are still questions there.  Salud

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.

PCB Trace Width Questions

Hello instructioners, So i am working on a PCB to use my XBOX 360 power supply as a standard 12volt 16 amp without hacking it apart. I've taken the female plug from a dead Xbox and I've recreated the layout in ExpressPCB. my only issue is being that its 16 amps @ 12volts is the trace widths to hold that much power are ridiculously wide we are talking 7mm or there abouts. I used several different online calculators to determine trace width.  My question is..  how small can i get away with for traces and still get 16amps.. is there a way of bridging the front and back side of a 2side PCB to allow for more amperage on smaller traces? i am really at a loss here. since my PCB is set at 38mm by 38mm and the connector size is 27mm long by 23mm wide. with 7mm wide traces i can't connect all the power pins together and all the ground pins together and route them out. Now i realize the 16amps is max draw but i'd like to plan for a max draw situation that way i feel confident enough to not have to check it all the time to make sure its not melting. Below is an image of the current board in Express PCB the labeled Thru-hole are connections i will need to make for this all to work. the other remaining holes are for mounting the female jack securely. The three yellow boxed connections are 12v+ The three greyed boxed connections are gnd ENG is bridged to +5 to make the XBOX PSU provide 12v

I am trying to build a couple of prototype boards (the kind with lots of plated holes), but I cannot seem to find the right wire. I want to solder the wire to the board, not use insulated wire-wrap, but any wire I try is either too thin, too thick, or is hard to solder.In the past I used resistor leads, those seem to be perfect for the task; now I want to buy some specific wire, but I am struggling to get a good search term I can use to find a roll of a similar wire.Do you have any hints on where I could buy a suitable wire for a prototype board?Thanks!

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!

Working SRv3 and Directional Mine Prototype

I haven't had the time to work on the SRv3 in a while so here is what I am thinking of doing. Let me know what you think. I want to release an ible on what I have built up to this point. Which by the way is a working shooting gun that shoots exactly how I want it to I just need the body, front, grip, stock, and bi pod to be designed and built. If you build what I present your SRv3 will shoot 500ft. What do you think? I want to make this gun a collaboration of design ideas so we can all build the gun as a community. Let me know if this sounds fun to you all. If so I'll post pics this weekend! 08/11/2013 Pics of both my working SRv3 and Directional Mine Prototype coming soon! Just a few fun stats of the two. The SRv3 has been recorded to shoot over 500ft and is extremely accurate. The Directional Mine launches 25+ K'nex green rods over 50ft in a nice spread pattern that can be activated by both trip wire and pull cord. Both are shooting great and are extremely fun to use! I hope to get a video and ible/forum up soon showing how to build both and how they preform! 08/14/2013 Go check out the Directional Mine Prototype on my ible NOW!

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. Questions and inquiries are encouraged. We look forward to learning more about your work. Please submit applications with all materials compiled in a .zip file titled with your project name to: P9PublicPrograms@Autodesk.com.

Cost of common DYI engineering project?

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!

Help Needed, 3D Printing Via Electroplating

A few years ago I saw a 3D printer that printed using UV reactive resin and a DLP projector and I obviously started thinking about ways to make this for myself. Recently I have been entertaining the idea of repurposing the old CRT technology with phosphors that produce UV light to replace expensive DLP projectors but I couldn't think of an easy way to do that. I was fiddling with various ways of repurposing one of my old CRT monitors when I had a decent idea. Instead of converting electron beams into light to harden resin why don't we harness the electron beams for the purpose of electroplating! Instead of resin we could use an ion solution and build models out of metal! Of course we would still need to replace the phosphors embedded glass screen with a conductive plate to serve as a non-consumable anode. Unfortunately I do not have the time or resources to do this myself so I wanted to post this to the Instructables Community and see If anyone felt this was a worthwhile project.  Please let me know what you think of the idea! I would love to see this turn into an actual project.
