Gear design

Hello there, I was wondering if you could help me: I need a simple program to design a basic gear, a pair of twin wheels. I need to set the number of cogs and the diameter of the wheels; this mechanism has to be as tight as possible. The idea is to print the wheels on paper and then cut a metal sheet accordingly; can you tell me a way to transfer the image directly on the metal? That would be of great help... Thanks.

Alpaca pack system designs?

I'm looking for a design (ie: instructions, ideas or patterns) on how to make my own Alpaca pack. The packs are too expensive to purchase from the local co-op or grange. I have priced them online as well and am completely shocked at the prices. If you have built this type of item for a llama, donkey or mule it is probably adaptable. We are looking to use our Alpacas around our farm to carry feed and tools as needed, and also to help carry firewood back to the house from the back country. Any ideas will be gratefully appreciated.

Need help to design mechanical mechanism

Hello everyone, I want to create feeder cart with seperate section, that will be hangin on rails.  Feeder cart will have four positions: First one (First load) will be bottom gates closed, middle gates open to the top. Second (Second load) will  be bottom gates closed, middle gates have to be locked in horizontal position. Third  position (First unload) bottom gates open, middle gates have stay locked. Fourth position (Second unload) bottom gates open and middle gates also open, that stuff drops out. I want ask you advice how to design bottom and middle gates open, closing and locking mechanical mechanism (without any electronical parts). This feeder cart will be operating by one man.  I have created middle gates mechanism, but maybe you have better solution.  I really appreciate for any ideas. Sorry for my english mistakes. English is not my native language. Link to my feeder cart design:  https://cad.onshape.com/documents/9bf2057d221de0e07143093b/w/42b5cff40a9a1fb3bed3cb14/e/cbc213062709ad380b4cb17b

Spanish fashion designer creates spray on clothing. Thoughts?

A Spanish fashion designer, with the help of the imperial college of London (I think I said that right?) has created "spray on clothes". Personally I think it's absolutely ridiculous and will never where clothes made like that, after all it's more like coating your body in silly string then wearing clothes, right? But, anyway, what are your thoughts on this? http://www.wired.com/gadgetlab/2010/09/spray-on-fabric/ (Image source: http://www.wired.com/gadgetlab/wp-content/gallery/spray-on-fabric/fabrican3.jpg)

Is this idea for a skateboard kite attachment practical or even a good idea? Answered

I was looking at some of the kite Ible's and had this random idea pop into my head about a way to attach a sail to a longboard to reduce arm fatigue and put more of the force directly on the board. I really don't know much about the physics or anything involved, but i would like to try this.  the image is a two minute MS paint picture to get my point across. shown is a two-tether design, but i assume this could easily be done with a multiple tether set up, and that might be better. Just throwing this out for ideas/comments/criticism.

Chuck Messer of Tackle Design and The Open Prosthetics Project on Smash Lab

I finally got a chance to watch the sneak preview of Discovery's new Smash Lab* last night, and imagine my surprise to see someone I know hosting! Chuck Messer, one of the four Smash Lab hosts, is a partner at Tackle Design the people behind the The Open Prosthetics Project, which also has an Open Prosthetics group on Instructables. Tackle Design and my own Squid Labs shared many similarities, so Chuck and I would share stories about how we each ran the companies; he even managed to visit Squid Labs when we were still located in Emeryville (pre-control tower). It's great to see good people getting wider recognition, and I wish Chuck and Smash Lab success!disclosure - Discovery is an advertiser on Instructables, and has been advertising for Smash Lab. This is not part of their advertising.

Great ideas!!

Hey guys, I've got to do a project for school that needs to be fairly large, and the time limit is now until around next October. Basically I have to be able to present something, not necessarily something actually built but maybe something planned or designed, etc, along with an essay and a few other science fair type things. I have a couple ideas for stuff I want to do, but one problem is that anything I do has to relate to a couple different "Areas of Interaction", such as say, community and service, human ingenuity, health and social education, and environments (meaning any interaction between people to people, people to animals, people to earth etc.) Some of my ideas include learning animation, like CGI stuff in movies, designing and building my  own guitar from scratch, throwing a band together and writing, recording and editing my own songs, or  maybe making a short film..not really sure so any help with idea generation and going about doing some of these things would be greatly appreciated :)

elliptical bike?

Has anyone ever heard of an elliptical bicycle? I came up with a design that would pedal using the walking motion of an elliptical trainer and you could stand up or sit down. I recently have seen a video from Maker faire and caught a glimpse of a bike with a similar design. Some minor differences included: The use of a chain ( I think that might give more room to walk/pedal opposed to my design with no chain), the pedaling is higher, and it looks more sturdy. This is helping me produce a better design. A glimpse at the other design is around 7:00 to 8:00 in this video. I hope someone has heard of it.

Does the Swiss Room Box inspire you? Without violating international patent laws, how about making something similar? Answered

Besides the price (over $8K, plus overseas shipping) it seems to take up an awful lot of space, and has some features like the uncomfortable looking chairs I wouldn't use.  But the idea of something that coud fit in a trunk of a car or the back of a minivan that could be used for camping is really intriguing!  Alas, I don't have the engineering skills to design what I'm imagining, but I have to believe there's someone who could use good ol' Yankee ingenuity and probably improve on the Swiss design.  If you Google it, there's a video that shows how theirs works.  Thanks for reading my question.  Suzanne

Building a full auto coilgun

I've been working on this project for about a year now, the first stages of the design started like 5 or 6 years ago. It is a full auto 19 stage no-capacitor coilgun. The accelerator is 3ft long! It will use an advanced coil timing system that should allow more efficient acceleration. The custom 3d printed magazines will hold about 90 shots, maybe a little more. It should be capable of firing at a rate of several thousand rpm but I might tune it down to ~500 rpm to keep it cooler running and make the ammo last. If you want to read more about this design you can see the page on my website: http://www.ourbadscience.com/#!em-guns/cwjy Here is a video showing the current progress on the coilgun:
