Standalone LED system?

Pages: (1/4) > >>

I want to add some LEDs to my control panel, but I do not want to tap into the power from my MAME pc.  I realize that standalone systems exist, but none are cheap enough for me (that I have seen).

Ahh easy!  You CAN use an old power supply with LEDs and resistors.  Make sure you calculate the values right and whether you're doing it in series or parallel.  Also, as for the on/off switch, you wire a switch to the +5 or +12 or whatever side of your circuit.  So where you get the molex, on the red wire, you would place the switch somewhere along that line before any of your LEDs.

Edit:  Why wouldnt you just use the power on your mame system?  It's basically the same, except it saves you a PSU.

Im not sure what you mean.  Are you saying you're building just the control panel to interface to a computer, or are you building one of those panels with a computer inside of it, so that you can just hook it up to a TV?  Good luck with it either way  ;D

I am building a free-standing control panel that can be hooked up to any computer with MAME on it.
