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

Default Re: my compact 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
