Hi,
Just wanted to share this with anyone who is interested. I built and used 2 of these controllers for this year's Christmas show and Singing Pumpkins for Halloween. I will be building 1 more for next year's show. These are fairly easy to build and are great if your not savy with a soldering iron. The board is fully capablable of turning the lights on and off at 50ms intervals....yes it is very click-it-y-click with the relays turning on and off but it does work and was a great starter for me to break into this hobby.
The downside is that the computer is only expandable up to 3 parallel ports so 24 outputs max...the upside is that they can later be used for servo and motor control once I figure out the whole SSR thing when the "itch" for expanding the show grabs hold!
The attachment reflects approximate costs.
The relay board was purchased at robotkits.com...cheapest I have found so far on the web!
Happy Lighting!
