A pal of mine who's an amateur radio guy (makes his own antennas, etc.) said he wished he could switch off the continuity beeper on his DMM because the beep makes his dog go nuts. So I knocked together an LED-only continuity test pen, with the light in the pen so there's no need to look at whatever the pen is plugged into.

I figured this might be a useful item for you guys. It's also very cool to make your own tools. Here's a vid. The video description lists the parts I used and how it all goes together.

Turn your meter to a resistance scale. It'll tell you a whole lot more without beeping.
