I have two more projects I'm exploring..
1. Cat5 cable tester.. has anyone created a circuit that is more than a simple 8 led light chaser circuit? line length, impedence, LCD readout on transmit pin, which line recieved it.. those kinds of things.
2. A SMALL, pcb mill/router project.. something that I can re-create a bunch of small 4"x4" pcb's with.. Not looking for a commercial mill, something the woodshop or metalshop classes could make and then the electrical shop classes use. SMALL desktop size, not overly complicated.
