Kemo Electronic

An electronic project kit to build a circuit that flashes a single or double output lamp or LED (max 300mA). This flashing project kit could be used in model making and model railways. A fun way to learn about electronic schematics and soldering. The LED's provided can be exchanged for diffe..

Kemo B015 5W Fog Horn Kit is an electronic project kit producing a fog horn circuit. The electronic kit produces a deep sound similar to a foghorn. Requires a loudspeaker rated at around 5W which is not included.Soldering is requiredOperating Voltage : 4.5V -12VFrequency of tone: AdjustableLoudspeak..

The kit switches on/off a relay at light and darkness (shadow). Usage: Whenever the light beam of a lamp on doors, windows, etc. is interrupted by a person, the relay activates. Also suitable as twilight switch. Can be used to open chicken hatch at dawn or operate a lamp at dusk etc.   ..

Switches a relay on or off depending on a preset temperature. Ideal as thermostat, ice alarm, fire detector, etc. it is possible to operate lamps, sirens or devices with loads up to 3A! Requires SolderingOperating Voltage 6-14V DCRelay Current - 3A @ 25VTemperature range: -30 to +150CDimension..

An electronic project kit to build a circuit that when installed into a hemispherical reflector (e.g. a plastic ball divided in halves) this highly sensitive microphone is able to record noises and speech from a distance of several hundred meters. Ideal for observing animals, for detective..

An electronic project kit to build a circuit that makes 2 differently coloured light emitting diodes flash alternately. Adjustable flashing speed/frequency. Usage: flashing adornments, name-plates, for miniature constructions, model making etc . Flashing LEDs can be used in model making and mo..

Electronic Project Kit to make an FM radio. The integrated audio amplifiers can drive an 8 ohm loudspeaker > 1 W. Pre-assembled SMD IC's and pre-wound coils simplify assembly. The kit can be powered by a 9 V battery.Requires SolderingA 8 Ohm speaker is required, see our shop for great deals ..

An electronic project kit to build a circuit that can be used as a universal amplifier for audio. The amplifier is rated at 1W with a maximum of 2W peak. Its small size means it can be integrated into many projects even when space is tight.Requires SolderingOperating Voltage 6-9V1W Output (2..

Whenever two bare wires have contact with water, the light emitting diode will light up. The device is suitable to release alarm in case of overflowing rain barrels and gutters. Operating voltage: 9 V/DC. As an add-on the kit B197 - Relay card 12 V/DC, which can be connected with this kit to..

With the aid of this project kit it is possible to carry out functional tests of infrared remote controls used in TV-sets and video devices, etc. Whenever there is radiation of infrared beams on the Special-Sensor, the LED will light up and indicate that the infrared remote control is oper..

An LED lights up if a body approaches the ultrasonic sensors at a distance of 10 - 80 cm (depending on the size of the body). Use: parking assistance for cars in garages, alarm signal for persons or animals staying in a certain area. Operating voltage: 9 - 12 V/DC. The device works accordi..

After releasing the push-button, the light signal rotates quickly at the 10 LEDs, slows down and then stops at random at one of the LEDs. During operation all LEDs shine except that LED that just receives the signal. That's why the luminous board looks very decorative. Soldering requiredOperatin..
