    Question What's the best DC-DC converter to build?

    I've seen a couple and I want to build one using a prototype board. Cost isnt too big of a deal if its within like 15 bucks or so. If you think it's the MK ones, which version? Thanks.

    The $60 one has a higher (10 volt) lowest-input-requirement - meaning, that if your battery dips too low for a moment, it'll kick out. I agree with going for the Arise unit, with a minimum input of (if 35-year-old memory serves me correctly) around 8.5 volts.

    Having said that, no-one has yet answered Dudah's question. (I can't answer it) Any other opinions here?

    Here's the power supply you're looking for. I've had it for about 6 months and haven't had any problems. Now if only someone could find a DC-DC ATX psu for under $100!
