Product details

Mindsets Sound Activated Switch Solder Kit

• Build your own sound activated switch
• The circuit responds to loud noises, claps and spoken words – though it won’t understand them
• Simple and fun to solder with 41 parts
• Requires a 12V power supply (not included)

What can I do with this kit?
Start and stop your projects and experiments with a noise. Activate the circuit with a loud noise, hand clap or spoken words like ‘off’ or ‘on’. Even though the circuit won’t understand the meaning, it will still respond. You can set the circuit to switch a device on or off or send a pulse at an adjustable time – eliciting a response from one of the outputs in a circuit. The switch can be used to turn on another circuit using up to 224V at 10 A (not suitable for directly switch mains voltages). This kit comes in 41 pieces and is great for anyone wanting to move on from beginner kits or practise their soldering.

What can I learn from this kit?
This kit is a great introduction to relays. Relays allow you to use a smaller circuit to activate a larger one. This relay has its own power source, and when it detects a loud noise or other stimulus it can complete a larger circuit (up to 24V) to activate an alarm or light. In ‘toggle’ mode, the first sound turns the kit on and the second turns it off. In ‘pulse’ mode, the first sound switches it on and then it switches itself off after a period of time that you can set on the potentiometer. This kit comes with capacitors, resistors, microchips, a relay and a microphone. The kit requires a soldering iron and solder and may require wire cutters.

How easy is this kit to solder?
This kit is ideal for those looking to expand their projects or wanting to progress to the next level. The circuit has a built-in microphone to detect sound and screw terminals to connect to your devices. You can add this in place of a switch in most circuits. This kit requires a 12V DC power supply (not included) that has a jack terminal.
