Velleman MK172

The Velleman MK172 Sound Star (Electronic Project Kit –Soldering Required)

Add a VU meter to your sound system with a different shape. The Velleman MK172 Sounds Star has 60 LEDS with 3 different colors (red, green and yellow). This kit responds to sounds and music in a VU meter style. Because of the built-in microphone, no wires are needed and with the adjustable sensitivity, you can put it anywhere. Use it at your parties, events or as an eye catcher. Build more than one to get a bigger effect. Finding a power supply should be easy with the wide voltage range (9 – 12 Volts DC @ 200mA).



  • Dimensions: 4.2" x 4.4" x 1.4"
