Re: Charger for Classic Message #3 Posted by Hal on 3 July 2006, 6:34 a.m., in response to message #1 by Giancarlo (Italy)
Hello Giancarlo,
The charger for a classic is actually two power sources in one... A constant voltage source of about 5VDC to run the calculator, and a constant DC current source to charge the batteries (which measures about 12VDC unloaded as I recall).
Building one, while not impossible, would certainly be a home science project. I would tend to agree with the previous responder...these charger are widly available on E-bay for a reasonable cost.
Best regards, Hal
