The RGB dash project

I found out what was wrong with the power supply. Made myself a high power resistor array with a couple of switches to simulate a load with set increments. At the minimum setting it pulls 225mA, at the maximum setting it pulls about 2.2A, still not the maximum this supply should be able to supply, but enough for my needs.

I found out that with my original setup, the voltage craps out quite fast:
22 ohm: 4.93V
11 ohm: 4.6V
5.5 ohm: 2.9V (!)

Then I put a honking big coil in that should have the correct inductance (hard to believe the little one I was using has the same value, probably doesn't).
22 ohm: 4.91V
11 ohm: 4.91V
5.5 ohm: 4.9V
3.7 ohm: 4.9V
2.2 ohm: 4.89V

That is feckin awesome! Just a shame that this big coil wont fit .
But at least I know what the problem is now, so I should be able to find a suitable replacement so I can get started with linking up the other boards.
