M3 Semiconductor Analyzer Kit
A few simple modifications make it more user friendly.
I built this in early 2006. I ordered mine with out a case. I added some transistor sockets to a case I had on hand. This is a very handy instrument, and I use it often. Well worth the price, and an easy kit to build. M3 has released a few software upgrades to it. Just pop out the old PIC processor, and drop in the new one.
I added 2 transistor sockets to mine. It makes testing the smaller transistors much easier.
