Last year I tried redrawing the cube in two dimensions and I could see how the vurrents were splitting but couldn’t solve it. Now here is a simpler solution that doesn’t require a lot of effort with whatever. I built the cube from 1k resistors and measured the value from corner to opposite corner, and

Me and my high school friend made a DC to DC converter that would give us 30 or so volts at a couple amps from a 12 volt battery. We used germanium power transistors which could not go much above 10 kHz. The Delco’s and the 2N458A’s were our favorites – we managed to push

I saw that meme where some clown replaced the 30 amp fuse in his car with a live .22 long rifle cartridge. That was a disaster waiting to happen! This is a true story – mid 1970s. My neighbor bought his wife a new sleek red Trans Am, and really loved how fast it could

A month or so ago a guy posted a plea on the Facebook group that he had these pallets of these 12VDC, 1.5 amp switch mode wall warts and he was desperate to get rid of them or he would have to throw them in the trash. He said he would take any reasonable offer

Caroline Joy Barnhart Your Kit must’ve had those “high quality” Radio Scrap components. 😆 My guess is you got one of the ITT2222 transistors. They made their plastic packaged version of the 2N2222 so that it did *not* conform to the standard E B C of the PN2222 or MPS2222. They were unpopular because they

This may apply to other states as well. Applies to cell phones and PCs. Does not apply to many other devices. https://arstechnica.com/gadgets/2022/06/ny-passes-right-to-repair-will-require-tech-oems-to-share-tools-diagnostic-info/
I use this for holding solder while I hold the PCB and iron with my hands. I use my teeth to hold this pen.
Caps Wiki – a place for you to share your repair notes. I like the idea. I’m wondering if I have the patience to spend the extra time. https://hackaday.com/2022/02/24/caps-wiki-place-for-you-to-share-your-repair-notes/
A string of LED xmas lights had been fritzing on and off, then it finally failed. I had to pull out 4 lights before I found two that were dead. I had to file off the ridge around the base to get them to fit properly into the base. So it’s back working again. It
