It really doesn't take a genius to read a schematic, check values, diagnose and replace the necessary components when you're only testing 1 rail, against ground. Its not rocket science, I know of positive and negative voltage, but I don't know if it's earth or case-ground, or ground for the...
Ok. I made a little diagram based on what I think it might be, drew it a couple different ways. I'm using 12v batteries as a reference, but if someone can just give confirmation that'd be awesome. The lines represent connections, and the pins represent the pins, based on their layout in the...
I'm well aware of positive and negative, but that's why I'm confused. How can there be a standalone 12V power supply over 2 negatives; if I were using 2 12v power supplies like you said? And how is it a center tapped circuit if the 3 wires on the right would share the same ground? Maybe im just...
Thanks for the response, so if I were operating with 24V DC, the connections would be positive/positive, and negative/ground bridged to -12v? I'm not experienced with these types of circuits, feeling kinda dumb right now
Just the post I was hoping to see, though I'm a bit late. I had a quick question if you don't mind, do you know the pinout for the input on the driver? I have tried 12V DC 2A on the "+12V" and "-12V" on the board (red and blue wires), as well as 12V DC 2A on the red and black wires. The light on...
Firstly, I'd recommend using 532nm for the green, as the color ends up being much closer to that of a true 589/593nm (I've built both, with 520nm + 638nm the color is yellow, but looks 'washed out' as 520nm veers on the 'blue' side of the spectrum). Regardless of which wavelength you choose, I'd...
"barnett_unlimited" user on eBay has a BOGO sale, 2 for $10 (and change), 4 for ~$20 etc. The diodes are extracted from a used, but low hour diode array. I've bought 10 lots (20 diodes) and they're in good shape, and work as they should. Just 2 of the 20 were *slightly less powerful than the rest
