It's actually a rather tricky little instrument to have around. I use it quite a bit.
Slight derailment of the original post.

That thing is based on the same microprocessor chip that the Arduino UNO boards use....I briefly considered building one using my UNO and some junk parts, but I still use my arduino occasionally, and it is cheaper and easier to just buy one of those testers pre-assembled, and make your own case.

Mine has already paid for it's self a few times over....The Dell computer I use to watch internet videos and odd file formats on my tube TV sets had bad caps in it's mother board and PS, and was dying. I was able to selectively recap it with parts from scrap boards using that tester. The audio still gets lousy after ~12 hours of continuous on time, but I can live with that.

Moving back towards topic: I wonder if those TV signal generator pens that were discussed on this forum some years back are singe chip.....I can't imagine fitting more than 2-3 in there unless it was all TINY surface mount stuff.
