AI Customer ServiceThat batteries you will be making will be low-voltage (~0.5V-3V) 1. Place one copper electrode (penny or Copper Disk) down on table. 2. Choose an electrolyte solution. 3. Place 1-2 drops of the electrolyte solution onto one paper towel membrane or dip one paper towel membrane into the electrolyte so that it become saturated.
A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions.
When the battery voltage falls beyond a certain low voltage threshold, the base current of T2 becomes sufficiently low such that it's no longer able to hold the relay into conduction and switches it OFF and also the load. The"LOAD" terminals in the above diagram is supposed to be connected with the inverter +/- supply terminals.
This low battery indicator circuit is used with a programmable unijunction transistor (PUT), since the threshold characteristics of the UJT could be effectively defined, and can be designed to flash a connected LED indicator. The PUT (Q1) is configured like a relaxation oscillator circuit.
When you choose to use a 6 volts battery circuit, simply shift the Zener diode to 3.1 volts. The circuit can be used with batteries of any kind, such as 12V, 9V, 6V, 5V, etc. You just need to adjust the value of the 5.1 V Zener diode according to the form of battery voltage.
A simple battery can be made by pushing a screw (best if it is zinc-coated/galvanised) and a piece of copper into a lemon and connecting these two electrodes using wires to the device you want to power. This cell can produce enough power to run an LCD clock/watch.
