The idea is to illuminate the watch dial at night with the help of a filling from a garden flashlight. A LED lamp and a solar battery are used as a power source. The latter is charged during the day, and at night gives up the stored energy to the LED.
Materials: solar-powered garden flashlight, clock, metal plate, double-sided tape, threaded sleeve (from an old chandelier).
Instruments: screwdriver or drill, drill bits for metal 6.8.10 mm and scissors for metal, glue gun.
From the garden flashlight, we remove the entire filling and place it in a new case, which will become the watch case. It will take a little alteration: install a solar panel on top of the watch at a certain angle.
From the plate we make a rotary holder for the solar battery, so that you can direct it to the sunlight. We glue the solar battery to the plate with double-sided tape and bend it at an angle of 45 degrees. Pull the wires into the sleeve, which will connect the plate to the watch case. We drill holes from above in the watch case and insert the sleeve, fasten with nuts.
On top of the dial, we also drill a hole for the LED. Solder all the wires into the circuit as before. We glue all wires with a battery and a board to the watch case so that they do not interfere with the clockwork during its operation. Putting the case together.
When the clock is located on the windowsill, the solar charge lasts for 8-10 hours of work at night.So a small alteration of the old watch brought great benefit!
