· Fly paper planes at 50km/h! Have you ever wished that you could throw a paper aeroplane as straight or as far as someone else? This kit includes components to make two electric plane launchers - ideal for exploring different paper plane designs. The rubber discs spin at high speed & will launch a paper plane at up to 50Km/h. An ideal gift for any budding aeronautical engineer interested in the application of technology to problem solving.
Requires 4 x AA batteries (2 per launcher)

Build this air engine racer. Designed to demonstrate the power of air under pressure this educational kit drives a propeller through an air engine. Pump the pressure up using the hand pump (supplied) and release the racer and watch it go, it sounds like a real engine in action.
Ages 8+.
This is a fantastic fun introduction to robotic toys. This easily assembled kit builds into a motorised robot which can be programmed.
Requires 6 x AA batteries. Ages 10+.
A complete kit for making an intruder alarm system. Once triggered, the alarm sounds until correctly switched off. Contains a thyristor, breadboard and all other components.
Single Channel Wireless Remote Control Kit ( Remote Control Kit 1 )
Complete remote control system
Switches up to 12A at 230Vac mains
Up to 70m range

Requires no radio licence A versatile general purpose remote control, which can be used for controlling many different applications such as garage doors, garden lighting, gate and door control, etc. The system utilises a highly secure code-hopping protocol to ensure safe operation.
Easy to install, the receiver is connected using standard screw terminals and is powered from 12Vdc. The output relay can switch up to 12A at 230Vac mains and can toggle on/off or switch momentarily when the transmitter button is pressed.
The system is supplied with one keyfob transmitter and the receiver can learn up to a total of 6 keyfobs for multiple users. If a keyfob is lost or stolen, then simply reset the unit and teach it a new keyfob code. Additional keyfobs are available: Order Code RN55K. Specifications:
Transmitter battery: 23A (supplied - replacement JG91Y)
Operating frequency: 433.92MHz
Receiver supply voltage: 12Vdc
Receiver current: 6mA (standby), 36mA (switching)
Relay output rating: 12A peak / 5A continuous @ 230Vac

External temperature sensor probe A compact and highly accurate temperature module ideal for use in applications where external/remote temperature sensing is required. The module covers temperatures in the range -40C to +50C in 01C steps, sampling period is 15 seconds. The external probe is supplied pre-connected to the module, cable length is 3 metres. Provision is made for either internal (silver oxide watch type battery, provided) or external power supply (nominally 1.5V), current consumption is 10µA. Connections are provided for display/setting enabling maximum and minimum temperature points, which are used to trigger a buzzer output. Connections may be made to the module using a 7-way minicon housing (female) and terminals (not supplied).

Three thin plastic films which have unusual properties. The thermofilm changes colour at body heat ,the glow-in-the-dark sheet absorbs and emits light energy and the lenticular sheet gives the illusion of depth.
Kit includes materials that exhibit a useful response to external change
Includes materials that change colour with heat
Includes metals that have a memory
Includes QTC - an insulator that becomes a conductor This pack contains samples of the most advanced and useful smart materials - those materials that exhibit a useful response to external change. Normally difficult or impossible to source except in products, these examples include materials that change colour with heat, metals that have a memory, an insulating composite that uses quantum effects to become a conductor - any many more. The instructions describe activities for finding out more about these remarkable materials that are setting the pace for product design in the 21st century.
A satellite-type solar panel plus high quality solar motor.
The motor will run in relatively low light conditions when connected to the solar panel.
Maximum output from panel = 4V.
Powered by air - completely safe
Works just like the real thing
Creates electricity How cool is this! A self-assembly kit that generates electricity from compressed air. Completely safe, all you need is a plastic bottle (not supplied), spin the fly-wheel and youll generate enough electricity to light the LED.
