 Well... FYI... I did built several HIGH SPEED recharging equpitment for
 my RC cars when I was in elementry school, and voltage difference are
 often not high enough to make them warm, let alone getting HOT (the
 Ni-Cad surely is getting HOT, but not the circuits)...
 Also Diode is for making the AC to DC, not regulating, for voltage
 regulating there are a few semi-conductor (Semi-conductor DOES NOT MEAN
 EXCULSIVELY DIODES!) voltage regulators... and you can easily find one on
 your motherboard if it supports 3.5 to 2.5 volt operation. They look like
 heavy duty transistors, but actually they are FAR more complex that that,
 but since they only need THREE connections, why not package them with the
 old transistor packaging machine? You see, Voltage regulator is not really
 a very delicate circuits... if the designer is in his or her right mind,
 the circuit will be a lot stronger than it needs to, for the fact that
 there are a lot of stuff can happen in real world... over engineer it a
 little bit is a cheap insurance against that.
