The glorious thing about engineering is we can engineer anything -- even our tools! Here are some clever DIYers' hacks to test tools.
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.
