Hi,
No more than you can pickup in the video. I am selling these so would rather not give away my secrets - 555, op-amp and a relay......:).
Ian.

It was there indeed. I looked at your video agian hoping to find a filename in the top bar, but it wasn't there. I found it looking for a string in your screen: "to keyboard2 cn2-5", and that sent me to http://www.circuitspecialists.com/pdf/3005X_schematic.pdf
Thanks :)
