This shows a homemade rechargeable battery that uses no lead. Both electrodes are charcoal coated with manganese dioxide. The electrolyte is Alum and distilled water
This is a homemade rechargeable battery that uses Epsom salt (magnesium sulfate), manganese dioxide, and water. The electrodes are both carbon rods out of a D cell zinc/ carbon battery. The MnO2 was obtained…
This is a super simple homemade rechargeable battery that uses stainless steel pan scrubbers with Epsom salt (magnesium sulfate) in plain tap water. The cell showed no voltage until a charge was placed on…
This is part 2 of my stainless steel and Epsom salt homemade rechargeable battery project. Here I show the cell boxed up in a clear plastic container and running my Led oscillator “Penny”. This…
This shows my homemade stainless steel scrubber rechargeable cell after a non-stop 12 day test using ambient solar energy to recharge it. My LED oscillator “Penny” was used as a constant load during the…
Here I show the 555 timer + 555 voltage supply inverter running on the regulated external power supply, as well as the most negative 12 volt battery in the main stack. As you can…
DC-AC inverter from two flybacks, based on spark-gap modulation by transistor’s oscillation (TROS); now we’ve got a readable AC…
This is a homemade LED lighting system that uses an astable multivibrator based oscillator circuit. The system runs on 12 volts but uses the new 110 volt LED household bulbs. Here is the link…
