The 555 chip with only transistors!
You can see the tresholds are 1/3 of the power supply and 2/3 of the power supply.
The relay is just for avoiding cfs problem

Good job niki, cuz its not just a plain copy from somewere, i can see you simplified some parts. E.g. missing output driver, RS latch different,... Anyway nice to see its working! Keep it up!
