I was mucking about with a switch for my cathodes and this happened : Luckily it was just the NIC, everything else works ok
I found a very interesting thing about 3com nics. I have a wire with gator clips on one end and a AC plug on the other, used for "testing" electronic components (capacitors originally) If you clip one lead to the metal slot cover and the other end to the small part of the PCI connector and plug it in, you get some nice sparkling. Try it out. The card's already shot.
Hey thing run on smoke and when that smoke comes out they no go i did that with a cellphone never went again
while back before i got broadband i was using my modem during a lightning storm, lightning struck, I got disconnected. Reconnected and got like the slowest speed. For the next few days it was still crawling. Opened up the case, took out the modem and stared at a big burn mark on it.
I had fun with a current limited 36 V dc power supply once: YOu touch one of the probes to one of the contacts on a chip, and run the other over the rest of the terminals untill you get a large current drain. you then hold it there, and smoke typically begins to pour out of the chip. i even had one explode
i still think watching 2 transistors on an inverter for a CC actually set alight in yor case and burn orange for a while is the best. shame i had 2 buy a new 1
CC inverters try putting a multimeter onto the Cathode side of its inverter, as the transformer inside ups the voltage (lowering current) the voltage will read something rediculus like 1000 volts. but whatever you do, dont short the pins or a continuous stream of 1000 volt electricity will arc between the two connections (dont touch it whatever you do).
