How to make a nuclear battery for your home clock that will last more than 10 years
Tritium is a radioactive isotope of hydrogen that is used to make luminous key fobs. According to the stated characteristics from the manufacturers, such a keychain will last for 10 years or more (on average, about 15).
Tritium itself has a minimal emission of particles and does not pose a danger in a plastic flask with a thickness of 1 mm or more.
On Ali Express You can easily buy these keychains or rods for various purposes.
On this basis, you can make a nuclear battery for watches or other devices. We will capture the emitted light and convert it into electric current using solar panels.
You will need:
Making a nuclear battery to power a watch
We disassemble the garden lamp by unscrewing 2 screws on the sides.
We cut off the wires and peel off the solar panel by prying it from the edge with a sharp object.
We do the same with the second lantern. As a result, you need to get two solar panels. Carefully solder the wires to each.
We connect the outputs from the elements in parallel to each other.We glue tritium rods onto one element using tape.
Cover the top with the second battery and secure with tape.
Wrap with foil.
We check the operation with a multimeter.
Approximately 1.5 Volts.
Take a clock or timer with an LCD display. We tear off the wires from the contact pads going to the power box.
We connect our nuclear battery.
Everything works like clockwork. Now such a battery can not be changed for more than 10 years.
