Homemade 12v power supplies
I am in the middle of upgrading my dew control system from a hairdryer and EPs in pocket to a proper one and have been looking at 12v power supplies. The battery option would be best as a few of the places I observe have no power.
I was wondering if anyone has had success building a unit to supply 12v power. The basic batteries can be bought from Dick Snith or Jaycar for about $40 and it shouldn't be that hard to rig up a sytem to recharge one. Any takers?
