Let's face it, sometimes the tools we get simply aren't the tools we want. Heck, often tool companies don't even make the tools we really want. Sometimes we have put a little work into the tools we have to get them to do exactly what we need for the job. An extra probe here, an expanded battery there, maybe even a complete overhaul of a display. There's always room for improvement!
Here's a pretty fun example:
Auto turn-off mod for a cheap multimeter.
The multimeter in question.
Florin only spent about $17 on this multimeter. He wasn't really expecting much at that price. However, he kept finding himself needing to replace the batteries after forgetting to turn it off. Such a simple problem can really lead to a lot of frustration. Florin could have simply run out and purchased another, more expensive, meter with auto-off function built in but he chose to modify his instead.
A quick, home-made printed circuit board (PCB) was quickly tossed together and now he has a customized multimeter with auto power-off! You can download the eagle files and code from his website if you find yourself in a similar predicament.
