I wanted to share a project that I worked on before Christmas with the help of Dr. Lava. I wanted to use the TTL outputs of the RYIA multibus with Laser Design Studio to sync my Christmas lights to music using the time line I was able to have a laser show let it snow come up first then the sync light show came up to Christmas Cannon. At first I was going to purchase an 8 channel TTL board but remembered that I had a Mr. Christmas lights and sounds of Christmas controller that I got a couple years back for 30 dollars in fact I had two I really did not like the cheesy midi files that synced the lights you had no real control over anything and the audio was tinny. I opened the thing up and to my surprise I found a 6 channel relay card that was connected to the main board that had the Midi eprom on it there was a multiwire connector that fed 3volts to the relays I removed the connector and figured out the ground then hooked up Christmas lights to all 6 channels. then applied 3 volts to each wire figuring out which channel it went to. I have attached a schematic so if you want to do this next year you will know the color code. After emailing Dr. Lava and asking him about the TTL capabilities of LDS and the RYIA multi bus he sent me a picture of what pinouts needed to be soldered in order to get TTL out I have also attached this be warned there will be some changes to the pin outs on the upcoming rev I did not use pin 7 and 8 so I left them unsoldered in anticpation of the update from RYIA, also the board is ESD sensitive so take precautions. Dr. Lava also sent me some files that I could load into LDS and see some examples of how to put TTL on the time line, one was an example one bit on one bit off and the other was all bits on and all bits off I ended up using both in the project here is the end result the first is the laser show and the second is the light sync with no lasers this year. I may add beams next year to that part if my Wife finds a new job both of these shows worked as an endless loop it ran for hours with out a hiccup. I put the audio in to a Low power broadcast stereo FM transmitter so cars would be able to hear it when they drove by sounded really nice for about a block. The laser show is let it snow I got it off the ILDA Swap ftp a while back and am not sure who to give credit to please let me know and I will, nice show I did not have time to put one of my own together so it worked out well.
