The spark was very small so I really couldn't hear anything really, I only had it on for a couple of seconds. The Fet was a little warm but the heatsi...

Are you using heatsinks on the diodes? You can´t connect the two diodes and the mosfet together by the heatsink or they will aways blow up.
Do yo...

Remember that the resistance of solder is about 10 times greater than copper, so if you have a high current track completely made out of solder, it is...

Ok.
I did find some data sheets of the LM311, LM211, LM111
I found this schematic in one of the datasheets.
