with a logic converter 3v to 5v (wrt54g router)
I would love to design a pcb myself for my Reserator XT since the freaking flow meter is shot I'm back on air cooling (have to reset every 5 minutes to avoid powerdown. wich is a pain in the arse since water cooling is pretty quiet.)
- connection for rbg led (that are fitted against the plexie glass to show the temp.
- offcourse temp controll.
and other stuff...
