This was the controller that I used for my fisrt Computer Controlled show. Just on & off, dimming was going to have to wait.
This second board I bought off of a user over at computerchristmas. I bought the parts & assembled it, but never tested it out.
The above boards use SSR's (Solid State Relays). The controller tells the SSR what channel to turn on & off.
This is a DC 16 channel board from D-Lights that I was, and admit STUPID enough to plug into 110vac. This board has now been replaced with a new one. I keep it around to remind me not to do it again.
I now have 64 channels of D-Light controller boards. 4 AC-8's & 2 AC-16's. So, with 64 above & the DC-16 I have a total of 80 channels. I will post pictures of them when I get them out of storage.
