The inside of a refrigerator or freezer is rather dry, in terms of the amount of water vapor remaining in the air, if not relative humidity. The dew point...

Hmmm... Heat and light seeking missile defense? Perhaps with a payload of tar to glom onto the bright lights?

Apparently there is now a trash bag vacuum challenge (saw it on James Corden):

OK, who will be the first to make an actual working machine with anthropomorphized features? Or at least 3-D printed "costumes" to put over...

I was walking my dog Muttley on the NCR trail some years ago when some cute young women approached from the other way. One of them said, "Oh, how...

Does anyone else first think of IPA as India Pale Ale?

Circuit boards are often washed with detergent and rinsed with clean water,...

Did you park that thing in the compact car section of the lot, again?

It would be simple to add a little thermostat to provide heat when the temperature is below freezing. Or maybe a little wiper blade. Technology for the...

Magnetic field strength is a function of ampere-turns. A 1000 watt microwave transformer can draw about 10 amps on the primary, and will probably have...

Long runs of pipe and pipes that are small or constricted will reduce water pressure at the end of the run. Every elbow, tee, and valve also causes pressure...

I think my water pressure at the meter is about 100 PSI, so a pressure reducer was installed when I had the whole house system done back around 1990....

That reminds me of a friend who bought some plans which were sent to him by email in PDF format. He was displeased with them and asked for a refund. They...

I have been storing some batteries in the refrigerator. It is a dry environment, which should reduce corrosion, and the cold should inhibit chemical processes...

It looks like a retaining ring, perhaps for a shaft seal or bearing. There appears to be an internal tang for a slotted shaft, and a set of outside tangs....

Just install a big mirror to blast the light back at the offender. And to be really nasty, use a focusable parabolic.

You should be able to find a watch crystal that will work. They seem to be about $5-$10 or so:

I bought a "Total Trainer" similar to "Total Gym" through FB Marketplace, for $60. Hopefully I will be able to get into a healthy...

With a 2.2 uF capacitor I find about 24 mA through each LED and 128 mA RMS input.With 96 volts on the LED array, that is 12.3 watts. At 210 lumens/watt...

I very much doubt these are genuine Cree LEDs, so all bets are off. It is possible for an LED to fail shorted, which would allow the remaining clusters...

If there are actually parallel groups of five, and there have been several failures where all five have opened and caused total failure, this "zipper"...
