I've been working on a project, and need your input! During the last couple of years at the Heritage Haunt, it's become apparent to me that there was need for a budget-minded DMX control solution for character animation as well as props. So, I've put together an interface board for the Heritage Haunt to use, and am wondering who else might be interested.
I have 3 boards being beta tested right now, but I haven't yet tested the extremes, so I don't have a complete spec for it. But here's the basics...
8 Servo control
Selectable 90 / 180 degree swing to support different styles of servos
8 Dimmer outputs for LEDs
Hi-rate PWM - no flicker!
String and parallel support
8 Switch-type (open collector) outputs for controlling relays
Connect to any DC-type relay
6V-12V supply power
Can use one supply for both board & servos
DIP switches for start address
Full universe support (0-511)
Use along with other DMX devices, or more boards
Jumper-selectable on board termination resistor
Use with other DMX devices, or more boards
No separate termination needed

So, I'm looking for both opinions on things I might've missed, as well as how many people might want something like this. The guiding principles here were...
1 - Make it small, so it could be easily hidden
2 - Support LEDs / servos / relays
3 - Require external resistor for LEDs (allows more versatility for voltage and current)
4 - Don't supply relays (see #1, would be significant and unnecessary cost adder for those not using all 8 relays, would lock-in relay type - SPST/SPDT/DPDT)
5 - Provide easy connection for just
signal leads of servos (simplifies wiring if wires need to be extended)
Lemme know whatcha think!
