Building on the XBee to PWM idea, I am currently working on a simple radio dimming system to dim some LED RGB strip via a DMX input, this time using an XRF module as the communications base. Boards are being prototyped, photos of testing to follow!
Februarys project is a wireless one. And closer to home that the recent sound control projects. The problem – wireless control of 3 channels of LED strip, powered by batteries and controlled by a lighting desk. There are a number of products already on the market to do this of course, but for this system we need many nodes without the cost.
The idea is quite simple, receive DMX, store only the values that we need and transmit out via a serial network of Xbee radio devices. The devices will each receive a set start address and provide 3 meaty PWM outputs for controlling the LEDs.
A project of two halves. A transmitter and receiver.
The XGO Pro is another collaboration with HAVE, this time on a device that is capable of switching toggling a KVM, changing the patch on an APATCHE (or other Sysex fired device) and provide contact closures to MIDI buttons. This switchover box contains USB MIDI cards to allow the connection of two complete sound playback systems and with one button, noiselessly transfer from one to the other, from an audience and operators perspective. “XGO” is X for crossover and GO the input from a button panel GOs, BACKs etc that are distributed to both systems.
This device is now built an in a testing and evaluation phase.
The box accepts OSC commands to set channel levels over the network and has a web interface for setup. A simple, mobile phone or tablet remote for your dimmers, just add a wireless access point of your choice.
You can configure the IP address of the unit via a web interface in a similar manner to setting up a router.
