RE: ATX based power supply. Need to vary output voltage on the 12 volt line.

I suspect the issue is that you're running more current (and thus power) from the atx psu than your other system. ATX supplies can put out absurd curr...

RE: Fluctuating-5 to +5 V signal

We need to know a few more details. Is this a digital +5/-5V signal, or analogue with that max amplitude? In either case, what's the highest frequency...

RE: Understanding components and how to read data sheets

Yeah... form factor is one of the quickest ways of reducing that number. After specifying through-hole at your link, you're down to 10, but remove "Qt...

RE: Transistor - emitter peak current at 23A (circuitjs)

Sure I did imagine that but the simulator surely needs that switch to be there to operate that way? Usually not. The simulator is going to start a...
