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…)

About relay module for clap switch- operate 100-240V appliance

connecting a lamp

Description: This is a dependent DIY kit module that has to be used with a clap_switch available at buildcircuit.net. This kit DOES NOT work independently as a clap switch. It is useless without this_clap_switch_kit. So, you need to order that kit also.

You can read about the clap-switch at this link.

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…)

4 in 1 DIY kit- dark sensor, latch circuit, astable multivibrator and clap switch

This is a simple 4-in-1 do-it-yourself (DIY) kit from BuildCircuit. The kit has four different circuits that can be switched on separately or together at a time using a DIP switch.

The four circuits are:

1. Dark sensor using LDR.

2. A latch circuit using NE555 timer.

3. Astable circuit using NE555 timer.

4. A clap-switch circuit using NE555 timer.

Besides these 4 circuits, by changing the values of the resistors and capacitors, you can change the behaviour of the circuits. (more…)
