Ideal for usage within miniature constructing and model making especially model railways and RC units! Lamps supplied seperately.Together with the additional kit "B197 - ..

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..

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.   ..

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..

An electronic project kit to build a circuit that after pressing a key this digital die indicates depending on chance, a number between 1 - 6. Indication takes place via LED's. An ideal electronic alternative to a traditional dice for games etc.Requires SolderingOperating Voltage 9-15VDimens..

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..

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..
