These are used Mobolazer G-beam DMX circuit boards in full working order - I bought several of these from Mobolazer when they closed up shop years ago.

They can be used to replace the motherboard in your broken G-beam, to build your own g-beam style laser light projector with Mabuchi motors (search PL for the G-Beam patent I posted for drawings & info, and a schematic I sketched) for actuators or can be used as a general purpose 8 channel DMX to TTL on/off controller. I use several of these for my Halloween display at my house to trigger effects by DMX. I also built a g-beam style beam projector with one of these boards in an old denon dj cd player controller w/ 8 red laser diodes.

Uses a 5 volt 1 Amp DC power supply wall wart (not included) and has 5 volt output on each of the 8 channels switched on/off by a TIP120 transistor. The transistors can drive LEDs and 5mW laser diodes directly or use them to drive solid state relays. I have mounted these boards in American DJ Autopilot Relay packs to convert the relay packs to DMX control.

There is also a 5v output from an LM317t adjustable voltage regulator to drive a laser diode (not included). TTL modulation input for laser beam on/off modulation switching. 5v output for fan connection.

DMX address is dip switch selectable so you can control it with any DMX console.

I will include a photo copy of the g-beam manual, and a copy of the schematic I sketched. The power supply and LED array are only shown to show that it powers up and works as described - they are not included.

All I/O is via header connectors and are clearly labels on the circuit board silkscreen.


These are on EBAY but PM me if you want one without going through EBAY.

I'm always open to trades for High End Systems "Laser Chorus" or "Viper Laser" parts, tubes, brick power supplies, cables or viper laser heads.
