My Second design of a small geometric sculpture that explores the battle between cake and pie

The human powered internet cafe looks at the issues of renewable power generation and aims to educate users to the energy requirements of surfing the internet.

Users are asked to peddle the exercise bikes in order to turn a dynamo which would in turn power the computers. If users fail to peddle hard enough the computer monitors will begin to flicker encouraging them to peddle harder.

The thing would ideally be placed in public areas where all forms of society could view it and try it out for them selves, thus educating as many people as possible.

This is a base for a bicycle light

3D model of the superman returns logo. Modeled in SolidWorks using an image as reference.

I made the head in Hexagon 2.5.0.5. I wanted the head to look like the head on the new Robotis robot DARwIn-OP.

For my wedding in October 2011 I asked my fiance if I could build something, she only asked that it not be tacky. This is what I came up with. It's a modular folding photo booth. I designed the model in Sketchup, programmed it in Autoit, and gave it a nice Glados voice. I needed an input device and I decided to make a serial comm button. I took a 555 timer and made it generate a 4.8kHz square wave. At 9600 baud this translates to UUUUUUUU plus one garbage character when the button is released. for now it only uses a Webcam to take photos but hopefully I will be find a deal on a canon power shot sometime in the next months to upgrade it. Since the printouts are resized, the small webcam resolution isn't noticable, however it won't be suitable if i wanted to incorporate the singles frames into a album. I'm working on some upgrades using the twitter api so I can have the booth update me whenever it is taking photos. This way I can tell it's status and share photos easier.


Here is a video of it's assembly and the software.

A small fixture that can be attached to a test apparatus, allowing a gyroscope containing device to be placed in a known position on the test apparatus to aid in the repeatable calibration of said gyroscope containing device

This is a Derivative of the original Yazzo PolyBot by WilliamAAdams. I found the original design to be something I wanted to build and test with immediately. So I found some things I wanted to do differently and wanted other people to experiment with this awesome robot.

UPDATE: The Female and Male Clevis Elbows I had uploaded here are the wrong size. I no longer have the proper size on my computer. Please follow these links to get them:

On the original Polybot the files were spread around Thingiverse and were very hard to find, I have consolidated them into one spot.

I have also changed the threaded rod connectors of the Tetrahedron support structure. These new ones should be much easier to print and will print without support. They should also be much sturdier.

I have also changed the servo brackets to make them much easier to mount the servos. You no longer have to take apart your servos and struggle with getting them back together in order to mount them. The servos also sit out further off the platform. With the original design, the servos sat too far in on the platform making it impossible to get a good range of motion for the servo arms.

One of the negatives of these new designs is the need for fasteners. The original PolyBot was designed to use as few fasteners as possible. This one can be edited to make the holes smaller on the printed parts for the threaded rod to fit snugly into without the use of nuts. I prefer to use nuts because it makes assembly so much easier. Nuts are pretty inexpensive too and you are probably going to be in the hardware store anyway for the threaded rod.

Currently, I am using standard Medium Hobby Servos to move the arms. For now they work really well and easily move the lightweight arms of this bot.

As for the micro-controller, I am using a Picaxe 28X/40X. But you can use whatever you like.

If you find this bot to be interesting, I seriously recommend printing and building it. It is pretty cheap to build and doesn't take much time. It is a lot of fun to mess around with. As for improvements, I already have a bunch of ideas in mind. And I know WilliamAAdams is working on improvements for the original Cranberry Yazzo Polybot, hopefully he will release something soon!

Here is a video of it moving... I should have gotten it to do something more interesting. But I have to go to work in the morning and I spent the night preparing the files and doing this write-up. Kind of lame, more and better video soon! I promise!

Another update... I couldn't leave it for the night with just that crappy first video. So I programmed some numbers that might make the bot look like it is moving semi-coherently.

So here is a better video of Delta Robot Movement:

Hanging file foldes trolley, folded when not in use, will be reflected as a decorative accent to hang on the wall.

Solid Works Drawings of a Mendel that is all metal, uses linear bearings on all axis and dual belts on X and Y to cope with extra weights involved.

This printer was started as a result of my friends astonishment of what i was able to make using a cordless drill and a hacksaw. my repstrap didn't sit flat or square it wobbled, i used lead screws to drive all the axis' as a result it was slow best speed i could get was 1000rpm ~650mm/min, but at that speed the frame wobbled and the resulting prints had waves in 6 different directions :P

This is my British themed Prusa Mendel.

I hope you like it.

I needed these for a couple of quick fixes at home. "mirrorholder" will fit the 10mm thick wooden frame of some 1m mirror sold at Ikea.
