“I’ve had this one TAC-2 controller lying around with a broken cord and one day I just got an idea that maybe I’ll convert it to wireless version instead of fixing the cord so I could use it for controlling a robot or whatever comes in my mind. I ordered a set of modules for a 433 MHz RF link from SparkFun Electronics (transmitter and receiver) that are easy to use.”

“We’re all familiar with optical fibres. These are usually glass or plastic fibres that conduct light from one end to the other with relatively little loss. While these are typically solid, I wondered whether I could make a ‘fibre optic’ cable out of plastic tubing and water. No longer a fibre I suppose this would be better described as a light-pipe.”

“There are some tremendous hexapods and quadrupeds out there already but they do tend to be expensive. One to two thousand isn’t unreasonable for these beauties. My goal is to work the low end of the spectrum and come in under $200 for a quadruped.”

“The main objective of this project was to design and create a robot capable of delivering a beverage to a specific location, when needed. To achieve this goal, two teams were combined and worked together into building an acquiring and delivering robot as well as a dispensing and replenishing station.”

“This is a project that I made to take care of an ever increasing need to prototype vacuum tube (valve) circuits. As you can see from the photos, it really is a test “board”. I do a lot of work with tubes and love to design and improve circuits.”
