https://www.npr.org/2021/10/21/1048246249/woman-killed-alec-baldwin-film-prop-firearm-new-mexico Hollywood is all about guns. The occasional on-set shooting death is just normal overhead. Hypocrisy of the ruling class. Our local newspaper is anti-gun, and the entertainment section is packed with ads featuring movie stars pointing guns. Money talks, I guess. I wonder if Baldwin will sh

The dryer here seems to be plugged into a 120V outlet. It's also on an extension cord. Anyone see anything like that before? I suppose it's actually a 240V connector which is the same size as a standard 120V connector but having one or more pins turned 90 degrees. Still, those aren't very high current. -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - ...

I want to inject a 100 ps test pulse into a 50 ohm transmission line, tee-wise, sometimes, from a 25 ohm source. So I need a series switch. I'd never paid much attention to PIN diodes... they are RF stuff. But this one is shocking: https://www.mouser.com/datasheet/2/249/MADP_008120_12790T-1921620.pdf 2 ohms on, 0.14 pF off. And that's packaged. Chip and beam-lead parts are even bette...

iPhones are purported to have kick ass cameras. But, do they "play well with others"? --- To Coda (TL;DR) Some years ago (20?) I purchased some DV cameras for a project, similar to this: Of course, when project was done, they just got stored (never discard something that you may need at a later date

I have a 24v DC motor that I'm using with a PWM controller supplied by a 24v SMPS. I want to be able to briefly switch the motor to 48v with a relay. I don't have a 48v supply, but I do have a 24v transformer & bridge. I know that the following will give me the 48v, and I think that the Motor Control will be OK with it. But I'd like to know if I'm missing something. The relay will d...

Hi Something that I have been coming back to a number of times: When placing capacitors for decoupling of a microcontroller datasheets often suggest a 1nF/100nF and maybe a number of them But it needs to be aligned to what is actually the load. Say I have a microcontroller running at 100MHz. Assumption (and that could be wrong), is that for the given technology the switching of the...

Very significant contamination occurred and has been quantified. The bad part is the fire raged in the least contaminated portion of the former laboratory property. The research is suggesting that a similar blaze occurring in the heavily contaminated areas would probably require the evacuation of LA. https://www.psr-la.org/study-finds-radioactivity-migrated-from-contaminated-sant

Close on the heels of Trump is issue No. 2: UNVACCINATED AMERICANS And this is sp...
