BB Power Supply Pot Problem (no not that pot)

[itsthemedication]

I just put together the BB power supply, and only have 29 more to go. One reason for selecting this PS was for the adjustable voltage, i.e. I needed a STABLE 1.9 volts (don't ask). Anyway, if anyone else is thinking about this excellent little board and needs a voltage <3 I highly recommend ditching the single turn pot (very imprecise and possibly noisy as well) and replacing it with an 18 or 25 turn pot like Digikey 490-2914-ND (92 cents). The switched 3.3 and 5 volts work great by the way!

nice hint! thanks for sharing!

Don't those multi-turn trimpots have a limited life? I could be incorrect in reading the data sheet but it seems they're only rated for ~200 cycles/rotations?

The way I read it, the resistance will change by no more than 3% after 200 rotation cycles.

Cool, thanks for clearing that up
