The picture Perfectly flush with the rest of the PCB gives me the shivers (https://home.comcast.net/~rburn/PCB-rework/images/fit3.jpg https://home.comcast.net/~rburn/PCB-rework/images/fit3.jpg).
I once held a power supply like that and by accident touched both contacts of one of the main caps, still charged, with my index fingers. Burnt holes in my skin and gave me a shock I could feel up to my shoulder. My arm still had a funny feeling to it hours later.
NEVER will I hold a PCB like that again. Even when I now, 10 years after dat, am repairing any device my body remembers what happened and makes me extra careful, almost scared.
Remember kids: always get rid of the charge using a suitable resistor!
- wil421 12y agoTry opening up a disposable camera and getting jolted by a shock from the flash's capacitor. It jolted me back and made a sound like a fire cracker going off. I had two burns and we were able to reproduce the shock by placing a flat head screw driver on the capacitor once it was recharged.
- tonyarkles 12y agoIn my youth, we used disposable camera flashes as the ignitors for potato cannons. One lead soldered to a screw, the other lead soldered to a bent coathanger. It's pretty amazing how many times those flash caps can handle getting a direct short!
