Whenever I go into a store like Radio Shack (great marketing on the name guys), I’m always a little shocked at how low tech it has remained. Behind the cell phones and overpriced video connectors that obviously are all that keeps them in business, there is a small section of simple electronic components and tools that look like they were some kind of Chinese surplus from the 80’s. Somewhere in the mix there will be a boxy over sized multimeter with a few functions on it and some giant tangly contacts. This is not an acceptable way to deal with modern electronics.
Enter the Smart Tweezer. The tips measure capacitance, resistance, inductance, and voltage. It will even graph out time varying voltage on the built in screen and identify components.
Unfortunately they aren’t cheap. They run about $300, when they are in stock.
