Not bad! What's the wattage on that pot though? And how much current do you plan on passing through the LM317?

According to my math, the power dissipated by the pot reaches a maximum of 39mW when set at 10Ω. It falls on either side of that setting.

Even the smallest of pots are usually rated for 100mW.

+1 from me.

That's totally the style of driver I used to love putting together. Mucho respect for the creativity :)

I can already see it - you're going to have a lot of fun once someone convinces you to grab a copy of Eagle and start making PCBs ;)
