I have wired a few toys that are 2AA batteries to a 5v power supply, no issues.
Curious on how to wire up a 3AA battery toy to a 5v power source?
Any ideas?

simplest way is to take it apart and look for a wire running to the positive end of one of the batteries in the battery compartment. Hook a diode with the band end hooked to that wire. Hook the positive from the +5v supply to the other end of the diode. Hook the ground from the +5v supply to the other wire from the battery compartment - the ground wire should attatch to the negative end of the battery on the opposite end from the battery with the positive lead.
Clear as mud?
