I got tired of having to wire up a a linear regulator, filter cap and a battery box just to generate 5 volts for my breadboard projects, so my latest project courtesy of BatchPCB was born:

Nicely done, Wayne.

Nicely done

but what runs on 5V these days?

Thanks. Actually, I usually run PICs and ATTinys at 5 volts for the faster speed. But, now that the PCB is proven, I have a few more boards on order and plan to assemble a few using the 3.3 volt version of the convertor IC.

Bonus points if you can use a switch to select 3 or 5 volt output.

I considered that idea but, unfortunately, the NCP1400A IC I used only comes in fixed voltage versions. There are probably other boost convertor ICs that can be switched to different voltages, but they'd probably need a different board layout.
