I've got a 16 port switch I'd like to use, but the power supply that came inside it (small circuit board) died and I took it out. I kept the thing hoping I'd find a cheap power supply of some sort. I've tested that the thing works with a PC PSU using the 3.3V connector, but that is just too big to be practical.
Now I have found a small 5V brick that puts out 1A and I think it would more than suffice to operate this small switch.
I had thought to just use resistors to drop the voltage, but a quick look online describes all manner of different circuits and many of them claim that just using a resistor would not be good due to fluctuations in current or something.
My brain still wants to think this could be as simple as using a voltage dropping power resistor or something.
Any input?
