Hi guys
I have an old compaq handheld computer i bought second hand on a recent trip overseas. trouble is, it ran at 120v and i misread the power supply. When i got home (i live in australia) i plugged it into the wall (240v) and started to get up to plug the other end into the Pocket PC.
4 seconds later i heard a puff and smelt some very strange cmoke. i'm just glad it wasn't plugged into the handheld.
anyway, i now have it in my car playing MP3s for me (from a 1GB compact flash card) and running my custom software i wrote. problem is i have to replace it's built-in batteries every week, and 4 AAAs cost a lot here.
I need to know what i would use to create a DC-DC power supply
any help appreciated.
--edit--
the old power supply output at 5V DC 1.6Amps
i have a 5v 1amp 78L05 voltage regulator, but that's not enough. i need 1.6amps. might i be able to wire two of these together or something to provide 2 amps?

ok sounds great. Tell me where I buy it.
couldn't find it in any of the electronic stores here.
Any electronics store should be able to order the part (or an equivelant). Just ask.BTW, Radio Shack does not count as an electronics store.
