LED Flasher using a Thyristor (SCR)

$2 for 10 PCBs & 24 Hour Production: https://jlcpcb.com

Just one active component in this LED flasher circuit - a thyristor or silicon controlled rectifier (SCR). With a couple of resistors and an electrolytic capacitor, the LED can be made to flash at a few Hertz.
