Some of you may already have seen this device, but I'm looking for comments - and also interest: I have enough spare parts for a few of these, although I am reluctant to build them myself - I am happy to sell self-assemble kits. Variable colour illumination thanks to red, green and blue LEDs. Multiple extreme brightness LEDs, produce light output approaching that of a luxeon star, but in a lower profile package, and without the need for heatsinking. Microprocessor control of the LEDs allows easy selection of a particular colour, or fading colour sequence. Anyway, enough text - I'm sure you want pictures - so here they are
I'd like to build one. Let me know how you'd like to handle it from here, but have to make sure to tell you, I'm in hte US so it might be easier to just get info from you and buy the parts myself. Am I right that it'll cost about £20 for the LEDs? (8*2+4*1)
that is very very cool. i would love something like that butwith blue, white, and UV *adding to future projects list*
Whypush: The circuit is quite straight-forward, and if you are reasonably competent I see no reason why you couldn't build it yourself, from parts sourced in the US. I will have to supply the CPU, as it needs to have the firmware flashed before it will do anything useful. The firmware still has a few bugs, and there are a few new features which are waiting to be finished - so it's likely to be a few weeks before I'd be happy to sell a programmed chip. I also suspect that you'll find it easiest if I supply the LEDs - you wouldn't believe how difficult it was to get these - you also won't believe how big the minimum order was (as I had to buy direct from the manufacturer's distributer). Note that it is important to use the right LEDs for this - the conventional shape 'super-bright', 'hyper-bright' etc. LEDs, have a very narrow beam, meaning that the colours mix very badly, and you end up with a spot light rather than even illumination. These super-flux LEDs are also so much brighter as to be laughable. Scoob8000: I'll draw some schematics up in a couple of days - but as noted earlier, you need a custom programmed CPU.
FWIW, I'm pretty sure that you can get those LEDs from http://www.markhannahsurplus.com/ in the US. He sent me a few.
Through that link it's going to run $24, and I'm sure shipping would be less within the US. It'll be interesting to figure out what the whole unit will cost. to build. And I wish I could type...
Im very interested in this technology for a few differant projects.

Could do some cool stuff with white when working in your case so you have decent lighting
That Sir, Is elite. The colour change is great, usually you can never get leds bright enough to do that, nice job
