    You sound so darn sure, I'm feeling confident! Would love to meet with you guys again.

    Hey since there seems to be some popping up in Bris-vegas, maybe we can have a Brissie Mini this year!

    (Sorry didn't mean to hijack - back to the peoples in the know).
    Ugh, this year will be too busy. I'd like to buy a vowel and more time please.

    Well as a newie ozzy to this fabulous little hobby, i need to contribute my commerical output cards (PLC cards)that have already been designed with proper casing and have the 240v implemented in the design. We need to hold hands together and make a few modifications to make these cards work for our Christmas Hobby.

    2010 will be the year were we can design and develop more robust hardware to suit the ozzy market.

    HO ! HO! HO! HO!!

    48vDC nominal can be actually higher than 50v, all my stuff is now specified to 60vDC with my nominal 48v LED strings running at an actual 50vDC and built to run at the 52.8v float voltage of a 4x12v battery bank (which i have but not connected).

    Same deal for all my 24v stuff, built around the concept of 26.4v Float voltage and happy to run at 27v.

    I bought 300w SMPS at 27V and 48V this year at $54 landed to my door, it's not worth the effort to design or build power supplies.

    I went down the constant current investigation 18 months ago (scorpio can testify) and discarded it as to hard and expensive at the controller level.

    All my 48v strings have 20mA constant current drivers used for each segment

    However this gets expensive for large numbers of strings at lower voltages.

    Software setable DMX addresses seem to be fairly well understood these days. The actual process could be better in my opinion, i've implemented it so that you push the button count 1 and release.

    Hi Phil,
    Those Supertex devices are neat. Might have to get some for another (non Christmas) project.

    Settling on a common DC voltage seems to be one of the bigger challenges in this hobby!

    ausiephil,
    i love the sea of flowers!

    Software settable DMX addresses seem to be fairly well understood these days. The actual process could be better in my opinion, i've implemented it so that you push the button count 1 and release.
    I use a push button and the first tree channels to show the status of the Address read and store
    LED Channel 1 - Found Start Address
    LED Channel 2 - Stored in Eprom Memory
    LED Channel 3 - Address store complete, waiting for you to release the push button

    When you release the button the LEDs turn off.

    Cheers

    Here is an image one of the many output boards that i have that we can modify an make it happen. Note the relays are 12v switching 240v-10amps.

    Yarnos,
    looks good, when you get a moment can you share some more technical details?

    I have managed to place some labels on the controller to give you a overall idea of what this output card can do..Snubbers protects the neutral from any back feed.These cards can be linked up to each other and can be addressed...I hope this all helps the electronic gurus out there.:p
    cheers
