I have an interesting project idea on the boil. It's planned for go-live in mid 2015 so iv'e given myself enough lead time so do all the research and testing properly.
In a nutshell - I want to build 120 individually controllable wireless LED modules
The idea is that cast on a stage will be wearing these modules, each module is individually addressable(Probably by an ID which is written in along with the program). From the lighting desk(Sending DMX 512, probably via Artnet tot he transmitter module which will translate ArtNet to my own signal) we can dim the LED on any one of the modules to produce patterns etc on the stage.
The DMX,ArtNet side of things isn't really worrying me right now, the bit that i'm stuck on is the RF hardware. I've played with the nrf24l01's and thought that they would be perfect but from what I can tell they require some sort of 'bonding' process kinda like Bluetooth, so I cant just have a simple 'broadcast' system.. Appears there is a max of 6 per network?
I'm not worried to much about data integrity or the modules ACK'ing to the transmitter etc.
I had planned on sending about 10 updates per second to each of the 120 units, so by my thinking that's 3 bytes per module per update(Address byte,PWM level byte and maybe a checksum byte) times by 10 updates per second over 120 units = 3600Bytes per second
This unit from Jaycar looks like it might in theory do the trick, any thoughts? - http://www.jaycar.com.au/productView.asp?ID=ZW3102
I haven't been able to find any reference info anywhere, lot of other projects do a many transmitters to one receiver type thing(For data loggin or security etc) but what i'm doing seems to be the reverse and therefor difficult to find any information on what others have done before.
