The board has a power resistor so to put a heavy load on the 5V output.
This increases the performance of your ATX power supply (which is a switch mode power supply), so to have better 12V outputs for the light strips.
A fan (standard 80mm 3-wire PC fan), which you have to connect to the board, will take care of dissipating the generated heat.
versioning
----------
the version is not defined is the files themselves, but are generated.
for the pcb:
- use `rake` to generate the outputs
- is will use the schematic `led-controller.sch`, produced a `led-controller_vX.YYY.sch`, and put the version inside
- is will use the layout `led-controller.pcb`, produced a `led-controller_vX.ZZZ.pcb`, and put the version inside
- `X` is the version of the board, defined in `version`
- version changes are described in `CHANGES.txt`
- version with letter (A,B,C,…) are releases, version with number (0,1,2,…) are intermediate working stages
- `YYY` and `ZZZ` are revisions, independent of the version and each other. they described how often the schematic/layout has been modified (git commits)
