This hack is causing a little stir around the web right now. And so it should, over at openschemes they have had a close look at the Mastech MS8910 smart tweezers. I have seen this type of multi-meter in ads on a lot of diy electronics sites and had been thinking about purchasing a set. It allows you to make one handed measurements of SMD (surface mount) components on PCB (printed circuit boards). If you have tried to locate a problem on a smd populated board using ordinary multi meter probes you can appreciate what a bonus this is.
Anyway what Openschemes found when they researched the design of their smart tweezers was that the IC has additional function not utilised on the design. With a couple of additions, the most expensive being a micro switch they have converted the smart tweezers to measure voltage on top of the original resistance, inductance, and capacitance functions.
