I'm thinking of running a DMX DC board as well. I'll need to do something to control those LEDs Al told me I'm ordering!
    Jack,
    When I first worked on building the floods, I did use RJ's MR16. So that path will work. I only built one of the 2 MR16 boards, due to one of the main chips being unavailable. Since then I built 2 of RPM's DMX8 DC board. Those were the ones I used to run them at the TASL mtg. They only have 8 channels, so would only run 2 independent floods each. But the boards are fairly small, so it's not too hard to combine them in an single enclosure.

    RPM (on DIYC) has designed a 16 channel board, or you could choose to use the LOR DC board. I tend to place my controllers out near the lights, and not have to run extension cords all over the place as much, so a smaller channel count per controller is better, for me. It's probably even more important when using DC controllers, since you have to worry about power loss over long cables to the floods.

    I will most likely be using the MR16 controller as a backup, depending on other projects this summer.

    Thanks. I'll go look up the RPM devices. I went in on the SSR4 co-op on DLA, so I'm at least partially committed to running DMX. That said, I'll probably put part of the cost difference between the LOR DC board and one of the DIY boards towards an iDMX1000. I'm not sure the computers I have available to me for the shows could keep up the constant data stream for DMX without some issues, so off-loading some of the cpu load to the iDMX1000 looks interesting to me.

    I suspect Al is going to do something similar, abeit on a larger scale than me.

    Jack,
    Just wanted to respond to the computer requirements.

    Using DMX doesn't require any more CPU than using any other protocol. It's the dongle that does the work. So if you're even thinking about buying an iDMX, consider buying an Enttec DMX USB PRO for about $140.

    All of this assumes that you're going to use something other than LOR S2 for the sequencing program.

    If you plan to use LOR S2, then, yes, an iDMX is the way to go. That's why Al is going the iDMX route, since he's also got the Servo Dogs, etc... It's a reasonable choice.

    But if you're going another route for sequencing, like LSP or Vixen (free) or something else, then you'll pay less and have less translation "effects" by using a DMX dongle. It's only if you buy the "SW only" dongles, that just do USB-serial conversion, that require a beefier CPU.

    There's a coop starting soon, I think on DIYC, for a good dongle that is a Enttec PRO clone.

    Just for you Al, here's Version 2 of my Mighty Mini control box. Using the weather proof RJ45-ECS connectors. These things are SWEET. When the Cat5 is plugged into the recepticals, and the fittings are screwed on, it is locked in solid! Now all connections including the RS485 data, can be accessed without ever having to open the case. Going to start retro fitting my first version now, to include the RJ45-ECS connectors.

    Gorgeous John. Will there be some airflow in the box or will it be completely sealed ?

    Thanks Denny

    Airflow ? some, not much. By my calculations, it would be rare for the power supply to ever exceed 60% of it's capacity. Heating shouldn't be a problem

    John did you ever check your LEDs out to see if they light up? For some reason I couldn't get the red LEDs to light.

    Thomas,

    The red were the first ones I did check. I just used a AA battery, so was a little low on the voltage, but they did fire.

    I found a 3 volt wall wart in my junk box that I'm using to check the others. Finished all of the white (cool and warm) then got tired, I'll do the blue and green tomorrow probably. Did check one of each though just to see the pretty colors.

    Thomas,

    I've now checked the balance of the LEDs. Mine are all OK.
