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.
