[highlight]source code now added below![/highlight]
Ok guys- my first guide on the forum please let me know what you think! If you follow this you will build a RGB moodlight with nearly 16million colours and 5 modes. The modes are: Random color generation (fade), colour cycle ( fade), freeze colour, colour jump (no fade), and slow down.
1) Ok start off by building the driver- you will need the following: Breadboard, solder, soldering iron, wire, 3X BC337 transistors, 4X 10Kohm resistors, a 4 in one dip switch (or 4 switches if you prefer), 1X 1gf628 PIC board (and programmer- or get the seller to program it for you), one 5, 10 & 15 ohm resistor and either 3 LEDs (red green and blue) or a single 3W RGB LED.
and of course a host!
Build the driver using the circuit plan: [highlight]NB this has been cut off on the right- there should also be a blue LED with another resistor & transistor like the other 2 LEDs - PM me for the full schematic![/highlight]
[highlight]NB2 depending on the LED config you may need an additional 3 resistors between the PIC and the transistors.[/highlight]
you should end up with something looking like this:
or this:
depending on how neat you are!
2)
With the driver built you need to heatsink your LEDs (if your using high powered ones- if not skip this step).
Take a CPU heatsink like this one:
remove the fan and any thermal paste left on it and you will be left with this:
Now using a milling machine (which I used) or a hacksaw cut the heatsink to fit your host/ LED, using thermal paste place the LED onto the heatsink and then hot glue (or screw) the LED in place taking care nto to glue over the actual LED bit (cable tie the wires round the heatsink:
3) Now with everything built, fit the LED and driver into your host (you nay need a light diffuser if your host isnt 'frosted' otherise the light will not mix/ will be too bright.
and there you fo all you need to do now is supply 5V DC and your done!:
now if you look in that photo- you should be able to see 2 of my builds there, as well as the original messy driver!

[highlight]comments welcome![/highlight]
[highlight]I can provide the source for the PIC if needed.[/highlight]

Assuming we have the technology to program one of these little suckers and have a blank 628 on hand. Would the hex file / source code be available for us to download somewhere? Source code might be even better because that would allow us to chose a different pic chip for instance.
