230 Volt Clap Switch circuit with NE555

This circuit is a simple Clap Switch using a NE555 and two BC547 NPN Transistors in a timer configuration, able of driving a light bulb up to 230 volts!
Principle of operation: Noise is received by the microphone capsule, the circuit with NE555 comes into action driving the relay (5/6 volt relay only).. At this point the relay closes the contact and powers the 230 Volt bulb.
Components:
- 1x Microphone
- 1x NE555 IC (no NE556 or TLC555)
- 2x BC547 NPN Transistors (or equivalent)
- 2x LED 5mm (any colors)
- 1x 2Ω Resistor
- 1x 330Ω Resistor
- 1x 470Ω Resistor
- 2x 1KΩ Resistors
- 1x 3,8KΩ Resistor
- 1x 47KΩ Resistor
- 1x 100uF at 25 volt Electrolytic Capacitor
- 2x 100nF Capacitors
- 1x 1N4007 Diode
- 1x 5/6 Volt Relay

Thank you!:)

Interessanti le sezioni di protezione con i diodi, e il filtro in ingresso con il condensatore.
Invece non sono riuscito a trovare il resistore da 2ohm sul diodo. A causa dell'illiminazione leggevo 22 o 220 ohm...

[@Stefano91ste]

Grazie Luigi! Quel resistore da 2 ohm serve a limitare leggermente la corrente al relè, io preferisco metterlo anche se si può farne a meno :)
Grazie per il commento!

Sure, I've been very busy lately but will be releasing new PCB videos soon

I need a circuit to measure the engine speed of an induction motorcycle. Can you guide me how to build it?

[@decem_unosquattro9538]

Hi Stefano, can I ask what flux you are using? 🤔

[@Stefano91ste]

Hi, lately I've been using an old solder paste that I've always been comfortable with

Circuit diagram pls

[@Stefano91ste]

Hi, see the video and take a screen shot for the circuit diagram

Its not clap on then clap off. What's the point?

Hi Stefano, I sent you a message via Instagram, please kindly check. Thanks a lot!
