We've been interested in building electronics relating to DMX for a while- leading up to a lighting desk. We decided to start small with a DMX buffer, and have got a nice one nearly planned out. However, after discussion last night about electronic kits that people sell for things such as amplifiers, etc. We discussed making up some modular kits for DMX applications, but before we dive into designing such kits we wanted to do a bit of market research.
The kits we would be likely to design would be the following kind of stuff:
- DMX to TTL/CMOS level converters
- TTL/CMOS level to DMX converters
- DMX decoders (DMX in to a parallel output for one or more address)
- DMX encoders (parallel input to a DMX output)
- Intelligent stuff to process DMX- DMX combiners, readouts of DMX values, etc
For example, you decide that you want to make a microswitch on set turn on a light, you could buy a DMX encoder, DMX combiner, DMX to CMOS and CMOS to DMX boards and wire them together in the following way:
DMX from lighting desk | DMX to CMOS converter | DMX Encoder - DMX combiner | CMOS to DMX converter | DMX to lighting rig.
Any comments, suggestions, etc welcome.
