How to make a light bulb flasher (or LED flasher) without any transistors. Really simple circuit.
To make this device you will need:
1. 12V relay
2. 2200uF capacitor
3. 100 Ohms resistor.
4. 12V power source (battery or a DC Power supply).
In addition, you may also need 10 Ohms resistor and 470uF - 1000uF capacitor if it doesn’t work without it.
