smart tweezers

Hi All,

I'd like to offer this project for your approval. You can buy these low-cost smart tweezer DMM for <$20USD but initially they can only measure R/C/Diode. By changing a logic line and rerouting an analog line you can enable the voltage measurement mode on the DMM chip to get a better tweezers for almost free!

Too big to paste here, so here is the link:

Let me know what you think!
