An externally hosted image should be here but it was not working when we last tested it.
I revised the board, new pic:

Update again:

Got an example of a shunt driver ? never used one.
I cannot use anythijng but what i have @ home so i hope it is something based on a transistor or something.
Actually i have never even heard of it. "shunt driver" on google gives plenty of hits but i have no clue what is what i would be looking for.

This sounds like shorting the LED to make it turn off faster, am i right ?
I understand it as this:

Bah sometimes one can be real stupid
Btw heres another board design for this thing:
Revisions are to come, as i have spotted things that can be made better. To tell the truth, i made this @ school today during a lession

That's good EDL!
Tekko, the use of 7805 to power up the 6N137 will give you start up probleme. Dont use electrolitic too on the decoupling of the 6N137. At start up, the time to charge them will result in a shoot trought of your mosfet (inverting mosfet driver...). Only use small 0.1uF ceramic decoupling cap and a stupid 330 ohms 1/4W and 5.1V zener for regulation...That's experience. The way you do it will bring you lot of trouble.
