In order to make strobe lights, you will need:
- LEDs: 1 red, 1 blue;
- battery box;
- battery;
- connection wiring;
- soldering iron.
Step 1. Dismantling the watch
Bending the latches, open the top cover of the watch.
We take out the printed circuit board with an electromagnet.
Disconnect fasteners.
We remove the electromagnet from the board and tear off its wires.
Step 2. Soldering the workpiece
We fix the board in the clamp and solder one of the two LEDs.
Observing the polarity, solder the wires from the battery container to the board.
Step 3. Checking the construction
We insert the battery into the container and check the operation of the stroboscope with one LED.
We take out the battery and in parallel with the first we solder the second LED, changing the polarity.
We insert the battery again and observe the effect of a flasher: alternate flashes of LEDs.
