Beautiful tree consisting of 134 LED's. 18 randomly blinking candles. No need to remove battery when using external supply. 12V operation possible for use in cars, vans, trucks. On/off switch included.

A good pink noise generator and a spectrum analyser are indispensable if you want to analyse the acoustic properties of a room (usually a living room). Moreover, you also need a microphone with a frequency characteristic that is as linear as possible (from 20Hz to 20kHz). If you have an equaliser, then the response can not only be checked but also corrected. The kit is easily adapted to produce "white noise"

RF ID access control kit with relay output. The kit can store upto 250 ID tags all configured via built in USB interface. Single relay output with timer option, pulse or toggle action. Feature 3 LED status indicators.

The Whadda WML116 unit can control DMX fixtures using a PC and USB interface. Test software and "DMX Light Player" software is included, a DLL is provided to write your own software.

Beautiful tree consisting of 134 LEDs. 18 randomly blinking candles. No need to remove battery when using external supply. 12V operation possible for use in cars, vans, trucks. On/off switch included.

USB controlled stepper motor card, to drive 4 stepper motors. While the motor turns you can simultaneously check the status of the dry-inputs (ex. emergency stop signal, limit detection...). Use the switch inputs to test the motors. Can be used in every application where positioning is needed (for example, plotter, printer, valves, automations …).

A 4 channel Infra-Red remote transmitter for use with a wide range of Velleman remote receiver kits & modules.

Sing along to your favourite music, hook-up the unit between your CD player, MD player or any other line-level source on the one hand and your amplifier on the other. RCA (cinch) input and output sockets with 6.35mm microphone jack, fits most microphones. Adjustable microphone level, "vocal reduction"-switch reduces original vocals on most stereo recordings. on/off switch and LED power indicator.

This unit allows you to control a relay by means of the well-known DMX512 protocol. This protocol was developed by USITT in 1986 to control dimmers, scanners, moving-head spots and other lighting devices with a simple wiring. In some cases, a simple ON/OFF selection is desired. This is where this VM138 comes in. It is actually a bus-controlled power driver. The relay will be activated when the DMX value of the set channel equals 140 or more and turns off when the value is 120 or less. Together with our K8062/VM116, a computer-controlled automation will be very easy to build.
