Worked on the chest circuitry some more...

Not too much but I added another 4017 chip to the circuit prototype for the chest electronics. This chip will control the pumping of fake blood back and forth between two chambers to simulate and artificial heart. I had more problems then I anticipated but that was due to a bad LED causing me to think things weren't working. Once I realized what the issue was, everything was fine.

I can't wait now for the Oscilloscope to arrive now. The bad LED would have been so easy to track if I had had one at my disposal.
