Cheapo MP3 player update

Hi all,
I worked out the timer circuit for turning the player on remotely. It can be activated with any dry contact switch (mat, PIR, manual switch etc) as long as no voltage goes to the player. I'll have the circuit for turning it off in a another week or so. I'm getting the circuit drawings done as I go, and will include pics. The first timing circuit looks a bit sloppy - a couple of false starts, and I'm not the best at circuit board layouts. Progress is being made! More to come...
