Xmas tree lights.

Posted 11-25-2010 at 09:10 PM by peonuser

Well I grabbed some 2n3904 transistors to act as solid state switches and now have the computer controlled xmas tree (battery powered) lights up and running. Still have to tweak the circuit and the code a bit though. The basic circuit before adapting it. Planning to use the parallel breakout cable to connect things to the pc. http://www.instructables.com/id/No-s...ort-break-out/. Good place for code and interfacing: http://www.epanorama.net/circuits/parallel_output.html

Also plan to add a heat sensor or two, so if things get too hot the pc will be shut down automatically. Have not built that interface circuit yet. Pretty simple though. I am not an electronics technician by any shape or means, but I can read.


Hope you are having a good Holiday! All for now.
