Epic Re:load v2 modifications



I have decided to upgrade the radiator for the FET to a bit larger one. I've also made some mountings form L shaped brackets for the potentiometer and have changed the original one to a 10 turn one.

Also, I managed to a really awesome knob for the 10 turn pot. The cool thing is that it calculates the turns and always shows the position that the potentiometer is at.

The original radiator resulted in the FET's thermal protection kicking in when running larger loads. That's the main reason for this "upgrade". The radiator I used is probably a bit too large for what I want to achieve, but it can definitely dissipate the heat that the FET produces.

I could not find any box laying around that the dummy load could be mounted in, so I opted out for mounting everything on the radiator itself. In the final version I moved the control knob and the banana connectors (can be seen in the title photo) to the other side of the radiator so that it's way more compact.

I do really like the final result. Of course, I should at least file the L brackets to make it look nicer, but the dummy load does what it's supposed to do.
