If there's a better site/forum for this question, please let me know. I have an old (mid 80's) Sears Craftsman generator - 4 cycle B&S engine & 120v, 1350W rated output. (Jeff - model 580.328172) I haven't used it in decades so I cleaned it up & checked it out with the intent to donate it to the Habitat ReStore. Imagine my surprise when I measured the no-load output voltage at 134v ...

At a fundraising event I found a very nice wood box in the electronics section. It has what appears to be a broken decades old multimeter at the top, and drawers full of parts below.

I'm basically curious i...

It's an old Dell R410, with supplies DPS-500RB (12V only) and D480E-S0 (12/5/3.3V). If the second one died, the first one can't make the server still run, as there's no 5V or 3.3V!

Recently I added an air cylinder to a manual lathe that opens the half nut when threading by moving the proper lever. For those who don't know a manual lathe that can cut threads has a leadscrew that drives the carriage along the ways when a split nut-the half nut-is clamped around the leadscrew. When the carriage has traveled the desired distance the half nut must be disengaged. Th...
