These are open source robots called e-puck, look like lots of fun. A little out of the hobbyist budget at $700, but for a research platform that is cheap! “The main goal of this project is to develop a miniature mobile robot for educational purposes at university level. To achieve this goal the robot needs, in our opinion, the following features: * Good structure. The robot should have a
Why buy test equipment when you can make your own? Edwin made a capacitance meter using a PIC16F873A as the brains. If you want to make your own there is code and a schematic provided on his site. “This is an autoranged version, which means one does not need to adjust the range settings.
