  • 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.

    I still think u should cough out the $79 and just (arise ace-865v) buy one that is PROVEN to work and will never FAIL! you. Also there is another one that cost $60 dollars i think. I don't remmember the site of the top of my head but i can dig for it if u really want it.

      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?

            Where can you get the 60 dollar one?

              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!
