History
We have always had rgb lights at NURDspace, and they are a great way to fine-tune atmosphere. As such, we have become accustomed to having them around.
As we were planning out the Projects:Geodome, it dawned upon us to incorporate this aspect of delight into the finished project.
Thus, this project was born.
Early on it was planned to become a 2.4ghz wireless system, but we moved to DMX along the way, as we had to run powerwires to all of them anyway.
Specifications
- 3W RGB-led sporting a 10deg narrow angle lens, mounted on aluminium heat-sink for sufficient heat dissipation
- 180 degree pan function for the LED
- 180 degree tilt function for the LED
- The brain of the node is the Pro Mini, featuring the AtMega328P uC which sits on top of female headers, so you can swap it out.
- Supplied by 24 to 5-6V, and regulated down by a Switching PSU to 5V.
- Power and signal are provided through Molex connectors
- 3D printed bodies for mounting the pan/tilt system and the PCB
- PCB is built up part SMD / part through hole
- Two modes of operation: DMX or standalone, selectable by DIP
- Big 3300uF cap for those dire times, electrically speaking.
DMX
- Each node has 6 channels
- Each node is addressable to 512 addresses by means of a DIP switch array
- Control channel for RED ranging from off to OMG my eyes!
- Control channel for GREEN
- Control channel for BLUE
- Control channel for PAN
- Control channel for TILT
- Control channel for pre-programmed functions. (As of yet; display_address(), beserk()) more to follow
- The DMX chip used is the LTC485S, currently operating in receiver mode. However the chip is capable of transmitter mode as well. The hardware supports toggling receiver/transmitter mode, but this feature has not been implemented in software. Hackaway, and turn the node into a DMX transmitter!
Standalone
- One DIP will toggle standalone/DMX mode. When in standalone mode, the node will perform various routines as configured by the remaining 9 DIP switches

In Village:Idiopolis there is a dome, about 4 meters high, you should be able to spot it. Look inside. :)
Also, they are for sale in the Idiocubator. (we made about 50 to sell, price TBD)
