LCD Panel Meter Kit

No Longer Available
A digital meter is a lot easier to read and much more precise than its analogue equivalent. Moreover, this panel meter is comparable to an analogue one because a regulated power supply is no longer needed ; in many cases, an ordinary 9V battery is sufficient. As a result of the compact meter construction, there will never be problems finding a place to install it. It can easily be combined with an adapter circuit or sensor
Dimensions: 50 x 72mm (PCB)
Power Supply: 8-15Vdc or 9V Battery

Stereo Valve Amplifier/Chrome Kit K4040

  Constructional Kit: Professional

No Longer Available

For most of us a high power valve amplifier is unaffordable. This kit changes that, so that now everybody can enjoy that sublime "valve sound". The sound of valves cannot be surpassed, neither by transistors nor FETs. In the development process, special attention was given to the housing so that the expensive valves are displayed in a visually attractive manner. The most vulnerable point of a valve amplifier are the output transformers; that's why we use ultra-linear and overrated output transformers (toroidal) to guarantee a rich bass response. To extend the life of the precious valves, the amplifier has a switch-on delay so that the high voltage is switched on when the valves are warmed up.
Dimensions: 425 x 130 x 350mm
Power Supply: 230Vac

Light Computer Kit K5201

  Constructional Kit: Average
No longer Available
Sixteen different programs and seven outputs make this light computer a unique showpiece. This kit can find applications in party lighting, discotheques, advertisement lighting, signalling, etc. To be able to view the programs directly, each output is provided with a LED. The complete circuit can be installed so that all operations and LEDs are available from the front panel. To enhance the spectacle further, an unlimited number of circuits can be connected together to work synchronously. Moreover, two programs are provided which are specially adapted to operate two light computers in cascade.

Temperature Sensor Kit

No Longer Available
This kit has been developed especially to be combined with K6002 to build a temperature regulation and control system. The advantage of a separate sensor lies in the fact that the distance between the actual controller and the sensor is of no importance.

Temperature Controller Kit

No longer Available
Unlike a normal thermostat, this kit has two outputs, one for "high" alarm, e.g. to switch on the air conditioning, and one for "low" alarm, e.g. to switch on the central heating. Both alarms are adjustable independently, each with their own hysteresis. Sensor K6001 included.
Dimensions: 117 x 60 x 80mm
