  • Generates a square wave between approximately 20Hz – 20 kHz
  • Simple and fun to solder with 18 parts

Product overview

• Build your own noise maker with an adjustable tone, to connect to a speaker
• Generates a square wave between approximately 20Hz – 20 kHz
• Simple and fun to solder with 18 parts
• Requires a DC 9-18V power supply (not included)

What can I do with this kit?
With this kit, you can output a square wave to drive a FET for output into large loads (such as a speaker) directly. You can generate and adjust a frequency between 20Hz and 20kHz. Use it as an alarm or scarer by connecting to an external input (not included). With a 53mm x 29mm board, you can fit this board in almost anywhere and connecting is quick and easy with screw terminals. With 18 parts, this is a great kit for those looking to progress from basic builds.

How does this kit work?
This kit contains the 555 timer chip, which have a lot of applications. This is a great kit to learn how they work. You can set the frequency using the potentiometer (variable resistor) and the 555 chip will create a square wave which can be used as a logic signal or connected to a speaker to be used as a tone generator. Get experience in soldering resistors, potentiometers, capacitors and microchips and see how they go together in a circuit. This kit requires a soldering iron and solder and may require a wire cutter.

How easy is it to solder?
This kit is great for those looking to move on from beginner’s kits and is a good introduction to the 555 timer chips – which are used in more complicated circuits. Once the kit is built, you can add to it with additional gear, creating an enclosure or connecting it to an input such as a motion or light sensor. The kit is powered by a 9-18V power supply (not included).

Rated 5 out of 5 by from A great product. Well at least it works! The future holds how it will work when I put it to the test. I am making a device to deter cats from my garden.

Rated 5 out of 5 by from Simple and Fun to assemble Needed to life test a new speaker for a project at work. This offered an inexpensive and simple way of powering an 8 ohm speaker at a variety of different frequencies.

Hi there is mention of an external input to trigger the unit . What is this and how can I use it ?

Asked by: badaaaabing
You can design any kind of trigger you desire, it would all depend on your particular skill set. To explain further the circuit generates a tone when power is applied, you could design a circuit to activate the power with something as simple as a switch or perhaps you could use a pressure pad or a beam barrier or a PIR detector.

What is the max output of this circuit in decibels (dB) to either a 4 ohm or 8 ohm (preferably 4) transducer? Approximately will do.  Also what are the dimensions of the unit?

Asked by: James
Board size 53 mm x 29 mm 1.5 mm, We cant advise on the dB level of the speakers used.

does it generate white noise? is there any way of modding it to generate softer noise (such as brown or pink noise)?

Asked by: greenwoodcolin
Maplin do not advise on the modification or redesign of units I am afraid
