Fully assembled clap switch for 100-220V AC light bulbs

DIY CLAP SWITCH

This fully assembled sound/clap operated switch can be used for turning on your 100-240V AC light bulbs. Usually, we use a clap switch to operate a lamp and it can easily do that for you. The kit responses to clap up to distance of 5 meters, but, the further you go, the louder the clap should be.  (more…)

The relay module comes as a pack of parts kit and is easily assembled if you can follow the silkscreen indicators (labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes. Both the kits operate with 9V batteries.

Step 10- Solder 5V relay and your kit is ready for blog

Features:

  • A DIY kit module that works with this_clap_switch_kit. It is useless without the clap switch.
  • >Operates a 100-240V lamp with clap/loud sound.
  • Supply voltage: 6V-9V. The same power supply can be used for this_clap_switch_kit.
  • There are two supply input points: a DC barrel and a screw terminal. You can use one of the points to power up the kit.
  • Dimension: 48.26mm x 49.53mm.
  • Relay specification: Activation voltage: 5V DC. Controls appliances operating at 10A 250VAC, 10A 125VAC, 10A 30VDC, 10A 28VDC. Suitable for Europe, North America, Australia and New Zealand.

Build a simple DIY clap switch

Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit.

Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting amplified. And it obtains a negative square-wave which used to trigger the bistable circuit from Q2’s collector.  (more…)

How to use an electret microphone

An electret is a permanently charged dielectric. It is made by heating a ceramic material, placing it in a magnetic field then allowing it to cool while still in the magnetic field. It is the electrostatic equivalent of a permanent magnet. In the electret microphone a slice of this material is used as a part of the dielectric of a capacitor in which the diaphram of a microphone forms one plate. Sound pressure moves one of its plates. The movement of the plate changes the capacitance. The electret capacitor is connected to an FET amplifier. These microphones are small, have excellent sensitivity, a wide frequency response and a very low cost.
