Hi all
I'm thinking of stripping out a PC case to use as a small veg box. I've got a few of the chinese 10w ic led's laying around from a custom car lighting project but no drivers. Since I'm trying to do this as cheap as possible I was wondering if I could use the atx power supply's 12v output?
The leds are rated for 9-12v dc input running at 1A.
I'm fairly handy with a soldering iron but no electronics whizz. I realise that I'd need a constant current source so is there an idiots guide on how I could convert the 12v output from the PC power supply to use with the leds?
I've heard mention of an LM317 but could someone who knows more than I do chime in to let me know if this is doable or if I should just spring for some proper drivers?
I used a 9v wall wart to test the leds and they all fire up, so there is a 3v headroom. I'm not particularly concerned with efficiency, rather simplicity of design and component count.
It just seems a waste to remove the power supply if there is some way I could reuse it easily. It would certainly help the stealth look of the case albeit at the cost of a little internal space.
Thanks for any input
