I thought it would be point less to publishing this, but after seeing "Sumobot Chassis by langfordw" I said to my self why not. The EEEI Robotic ieee.rutgers.edu/robotics/ club at Rutger was inviting all student to joint the line following competition to build a robot from a kit. More detail description of the kit can be found here ieee.rutgers.edu/robotics/attachments/069_Kit_Description.pdf. They also made four classed meeting once a week for student who have no skill in soldering or programing to assemble the kit. After the four classes student have two week to prefect their bot before the competition. The kit costs $65, but since I already had Atmega sitting alone in a box I decided to get the kit without the Freeduino for $45. I got chance to use the Atmega and learn how to program it. I could not let this opportunity just pass by.

I was inspired by zignig's Printable Desk Clamp thingiverse.com/thing:683 . I used hex nuts instead of square nuts because hex nuts are more common. All the parts are easily available at hardware stores and hobby shops. The total cost is about $4.50 for this clamp compared to $50 ones. It is used for holding circuit boards at comfortable angles, hobby modeling, and holding stuff. Enjoy.


The picture of all parts does not show two nuts that I had already hammered in but I did not want to take them out. Also it does not show 20mm brass tubing as I already hammered some of them in.

I made this bike mount at my good friend's request. The mount is fairly heavy duty. The estimated cost is $0.80 of ABS material at $0.02 per cc. I printed it with a honey comb structure making it strong for vertical compression. As a tip, I recommend coating the mount with epoxy for easy clean up and then paint it with a "Sharpie". Enjoy.

Burr Puzzles are traditionally made of wood, but I made one that can be printed by a Cupcake. There are six pieces altogether with about a little more than a dollars worth of material. The puzzle is design for a perfect fit. If you want to make it more loose then you can modify the stl files for each piece. This particular puzzle takes fifteen steps to put together so it is quite fun. However, trying to figure out how take it apart is as much fun.
