I just reviewed my suggestion from yesterday and I realize that I forgot to mention that the Xantech 599 pulse generator needs to be connected to a Xantech 590 (or equivilent) infrared learner. The stop and play commands of the CD player are stored in the learner.

That's the problem with giving advice late at night-- I get forgetful.

A diagram makes the circuit a lot easier to understand. I is actually very easy to assemble and program this circuit, even though the parts add up fast.

E-mail me if you want a diagram.
