Self Powered

The serial rs232 uart port on the de2 and neek boards can all be used for midi.

Standard schematics can be found all over the web like here:

The interresting mod i have made was to make it self powered via the txd output of the rs232.

by adding a diode(only nessesary if you need midi output i think) and a small capacitor.

So that it gets power from the rs232 port txd line.
