This compact amplifier module kit packs a surprising punch for its size!

(EA Jan '99) A very simple, yet extraordinarily effective deterrent to car thieving persons. Controlled by a hidden switch inside your car, this alarm will sound an ear-piercing 110dB piezo siren inside you

Up to 12 K5250 Intercom Sub-stations can be used from this one power supply.

Kelvin, the electronic cricket, is a bit of a smart alec. Just like a real cricket, he only starts chirping in the dark. And also like a real cricket, the warmer it is, the more rapidly he chirps. So you can actually tell the temperature, based on the sounds he makes!

(SC October '11) This new LED light slave controller kit will operate with the K 5885 master unit. Drive up to eight strings of LEDs, each string with completely individual control. Up to four slaves can be used per system - that's 32 channels of l

(SC Oct/Nov '12) Accepts audio input signals and drives coloured LEDs "in tune" with the music. 16 output channels respond to different audio frequency bands and the light brightness is in proportion to the

(SC September 2012) Fully upgraded Maximite design, see below for list of upgrades. Ideal for datalogging, monitoring & switching relays. Utilising the new Microchip PIC32 processor, this powerful embedded computer can read/save programs on an SD c

(SC Feb '12) This tiny regulator board outputs 1.2-20V from a higher voltage DC supply at currents up to 1.5A. It's small, efficient and cheap to build, with many handy features such as a very low drop-ou

(SC Sept. '94) Compact miniature design uses only one IC to switch a relay. This versatile Vox circuit is triggered whenever a noise or sound is made (via the microphone) causing a relay to close for a preset time.

(SC November 2011) The idea behind the miniMaximite is simple: to shrink the Maximite down to the size of a large postage stamp while keeping it 100% compatible with the larger version in its external I/O capabilities and programming language.

If you need to switch mains voltages, say from a micro's out- put or any other low voltage source, you need to isolate them from each other. That&rsquos what this project does - it's easy to build and keeps mains voltages locked away from the controller and you! Virtually any low voltage source will do - from 2.7 to 10V.

(SC Aug '03) Simply connects to your serial port and provides remote control of Winamp and WinDVD software packages. In addition to this it can also provide a host of other PC automation abilities. Great for watchin

(SC January '09) Want to try your hand at 'stop motion' photography? This camera shutter/flash controller allows you to take a picture at a precise moment between 1ms and 9.99s after a trigger. Triggering can be from the included electret mic

(SC Nov '11) Power Supply Board for K 5165 135W Ultra Low Distortion Amplifier.

This is the recommended power supply for the K5116 Amplifier Module Kit.

This remote control mains switch can be programmed to switch appliances on and off after a set period or to switch power on and off at set times.

(SC Jan '16) The quick brake module is designed to detect fast pedal movements between the accelerator and the brake, switching on the brake lights of your car before your foot reaches the brake pedal. This gives other drivers more notice when travelling behind you and reduces the risk of a rear end accident.

(SC August 2010) Switch low voltage devices on/off after set periods. Operated by the included A 1012 universal remote control.

(SC June '02) Add a remote control volume to your latest audio project or amplifier. Ideal for building into amplifiers or pre-amps. It features PIC controlled precision and a motorised pot so the knob will move whe

This simple SMD Trainer project is a great way to practice soldering a variety of surface-mount devices.

(SC April '17) This two spring tank type reverb unit provides reverberation effects for your guitar or other instrument. Adds complexity and depth to your sound to impress the punters. Easy to build and integrate into other projects thanks to its 9-15VAC or 12-15VDC power requirement.

(SC Nov '11) Loudspeaker Protector board for K 5165 135W Ultra Low Distortion Amplifier. Protects your speakers and amplifier from short circuits, Over temperature and DC faults that can occur.

(SC Jun-July 2014) Record CD quality sound directly to an SD card with this touchscreen recorder. It offers hours of recording and playback time from an internal rechargeable Li-Ion AA battery and may be recharged via USB. A stereo line input and mono mic input are provided via 3.5mm jacks, plus an internal microphone for instant handheld r

(EA Aug '97) A flexible circuit that provides preset voltage output of 3, 5, 6, 9 or 12V DC. Suitable for powering a wide range of DC low power circuits, such as running a personal CD/radio from a car cigaret

This compact alarm can be used to monitor the operating temperature of a whole range of devices. You could use it to monitor your tropical fish tank, your home brew, freezer, fridge, your hot water system or where temperature monitoring is useful.
