I wanted to build the alkaline battery charger in the diagram below and was hoping someone could confirm a few things about the circuit. I'm not sure who the original author is.
1. There is no connection for the Base of the transistor in the diagram ? What should it be connected to ? Directly to ground ?
2. Would it make sense that the variable resistor is 47 Ohms or should it be 47k Ohms
3. The circuits calls for a 9.5v AC power supply. Could I power this with 9.5V DC knowing that the second 1.5v charging circuit ( lower in the diagram ) would not work.
Thank you
