Velleman Kits & Projects

Velleman K/LEDHDR, a small packet of Red 5mm light emitting diodes (LED's). Suitable for use with Velleman K5600R advertisement LED display Kit.

Brighten any room or space with this fully Arduino® compatible, ESP-32 controlled BrightDot clock kit. This designer matte black edition clock features 60 bright RGB LEDs that reflect against the surface on which you mount the clock, hence telling you what time of day it is. The SMD RGB LEDs are pre-assembled but the rest of the solder work is up to you! Solder the light blocking pads into place and connect the clock to the ESP-32 by using the data cable. Then it's time to pick out a nice spot to hang the clock with the invisible mounting option! Once you've overcome the choice overload of available hanging spots, you can connect the clock to your wireless network and it will sync automatically with the NTP time server. Afterwards, you will be able to control every animation, colour or setting that is available by using the built-in web page which is accessible with your smartphone or PC. Another choice overload situation! Other cool features include the alarm and the LED auto dim for when its bedtime. Check out the videos to see some cool time animations that you can display with the BrightDot clock!

Suits all Velleman kits requiring a regulated power supply between 5 and 12VDC, and no more than 1A.

Universal low-noise stereo pre-amplifier.

RIAA stereo pre-amplifier for MD pick-ups. Low noise.

Up to 3 different time intervals (5 - 10 - 15 seconds) can be selected for the windshield wipers of your car. It can also be used for automatic slide projection.

Flashing light effects for discos. Make your own snapshots and "lightning" light effects. Flash frequency adjustable from 2 to 20Hz.

Connecting a number of relays to the outputs of an electronic circuit may seem very simple, but in reality it might possibly create some problems regarding the cabling. This kit provides an attractive and compact alternative. Moreover, it can be assembled and connected very rapidly.

This kit provides an acoustic measurement of radiation levels. The sensitivity is at its highest for gamma rays and high energy beta rays. The assembly is compact and may be mounted into a small box, together with the 9V-battery.
