I'm looking at using the 12V flashing LEDs from here:
**broken link removed**
So from what I understand if I put several of them in series I would require more than 12V power. But to put them in parallel each LED would require a resistor? That sounds like the way to go I suppose. What...
Thanks! Yes - it is a wall AC adapter. 12V/1500mA. How many 12V LEDs could I conceivably run off of one of these? And could I run multiple parallel circuits off of it? For instance - 3-4 LED panels with x LEDs each and an off\on switch for each panel - each running parallel off the one AC...
Clicking is bad
Clicking means there is a problem mechanically - software recovery program probably won't do the trick (unless as other suggest, you pay the big bucks and send the HD off to a data recovery company). One thing to try (and you may have tried it already) is to add it as a slave...
I have been tasked with designing a "spy kids"-like console with radar images, flashing lights, working switches, etc. I have the pc parts figured out, but am a novice with electronics - last time I built a circuit board was as a kid.
Wanting to setup a few simple flashing LED panels with...
