I am having trouble finding a powersupply to suit my needs. I am working on a more functional ATO or Automatic Top Off controller for an aquarium.
The one you see here is a simple five volt relay board and the powersupply is an AC/DC making 5v/12v but only at 1a. Fine for the 5v side and in its present configuration on 12 as well. The pump I am presently using is not drawing but about 750ma max. I want to have it able to supply more amps to support a larger pump...while still remaining as small as possible. I can find plenty as big as a juice box but also with more amps than I might ever need...I figure 2a to 3a should suffice. Anyone seen any like that?
...or, know how to make one from scratch?
