eBay Transistor Curve Tracer Kit - Build,Test and Review

I found this inexpensive transistor curve tracer kit on eBay for about $25, including the power supply (transformer not included). After soldering all the components to the PC Boards, I wired it all up in a home made case and tested it out. It actually works! You just have to be very careful not to connect the transistor incorrectly, or it will fry it pretty fast. Check it out.
