Would you trust this gadget? https://omg-solutions.com/multifunctional-detector-rf-signal-mobile-phone-camera-lens-magnet-det ector-1-8000mhz-spy991/ I expect it would constantly beep false alarms. -- Rich

This is pleasingly weird. https://www.dropbox.com/sh/sif3efs69dxe1mg/AACY0RJGXl4k8CVvauUbJtYFa?dl=0 Sort of a baseline-boosted multi-auto-transformer voltage-doubler flyback. What's strange is that adding the two snubbers increases the LT spice sim speed radically, about 10:1.

It feels like the Digikey data sheets are now often links off-site, and those links are now often broken or plain wrong or otherwise useless. Plus, most of the parts are unavailable or insanely priced. They show several relays over $50,000 each but they are fortunately unavailable.

Single point thermal imaging camera made of infrared thermometer Let me know your opinion and experience since high resolution thermal imaging cameras are still expensive so I plan to build a single point thermal imaging camera supported by mosaics scanning mechanics to get high resolution thermal imaging thank you

I am seeking data on what radiation doses electronics on a satellites get in both low, and high, earth orbits. I need this in units of Gray (Gy), or rem. I know radiation exposure will change depending on Solar Cycle Phase, and the orbit, especially if polar, and also when passing over the South Atlantic Anomaly, and shielding. What I need is typical exemplar data for a short mission ...

The Raspberry Pi pico has its 3-pin SWD debug port. I'd like to connect it to the 40-pin header on the back of the Pi400, to use the 400 as the dev/debug platform for some RP2040-based boxes. Has anyone done this? What Pi400 pins connect to the SWD port? Googling doesn't help. I have the RP400 Beginners Guide book and it doesn't mention doing this. Anybody have links about doing this? ...

There is a new-to-me power supply architecture, an H-bridge driving a load, but with the phases on the two sides slid around to control delivered power. TI does that in some chips, like UCC2895. I may have seen the architecture first in this ng. Anyhow, I was thinking about a high-voltage power supply with the phase-shifted bridge driving a series-resonant transformer. https://www.drop...
