I am working on a circuit for my deer feeder.

I now have a 6 volt power source running the spinner on the feeder and it has a 6 volts solar panel recharging the battery.

I made a new circuit control out of a disposal camera circuit trying to make a shocker device, of two cages, one interior and one exterior isolated separately and the shocker circuit connected to them, I get 300 volts to my cages. This circuit requires a AA 1.2 volt battery.

How can I make the AA rechargeable battery, charge off the existing solar charger?

I have an idea but not sure. Can I go off my solar charger that's existing and cut the voltage using a resistor circuit with a diode or make another circuit of several diodes in series and get down to the 1.2 volts?

Or option 2 second-ally build a 1 volt 1 amp solar panel supply, adding a diode and connect that to the 1.2 volt battery that I want to keep charged for my shocking device.

    \$\begingroup\$ @Hearth A buck converter? To what? The deer are just fine the way they are! \$\endgroup\$ – duskwuff Jan 30 at 23:17

Lookup the datasheet for a Ni-MH AA rechargeable battery cell to see how much voltage it needs (1.4V to 1.5V) and about 380mA to charge for 6 hours. If you simply use a resistor to reduce the current to the 1.2V battery then the 6V spinner might not have enough current to spin.

  • \$\begingroup\$ Audioguru If I keep my voltage of 6 volts from the solar charger to the 6 volt battery which run the spinner and go back up the wiring from the solar charger and parallel another circuit knocking down the voltage to the 1.2 volt AA rechargeable battery will that work and keep the 1.2 battery charged also. In follow up to other comments the raccoon tears into the feeder and steal the corn for the deer. \$\endgroup\$ – Bill Downey Jan 31 at 2:26
