“Two cool projects I’ve just finished. One is a function generator, the other is a PIC USB prototyping board. After aquiring a brand new 20MHz Two Channel Oscilloscope, I felt I needed something to actually use with it. Including component selection, designing the circuit, breadboarding, PCB layout, homemade PCB manufacture through to the finished product.” – Link & PIC USB board.
Function generators seem to be popular at the moment.
