Yes, when I looked inside myself that weekend, I found within myself everything I needed to produce the ultimate charcoal cooker temperature control device. I had a built-in central processing unit, and I found that if I used it, I could determine a target temperature. Then using the visual receptor devices in my eye sockets (not depicted in the above diagram), I could sense when temperatures were rising or falling. By using the actuator linkage circuitry built into my body, I could effect changes in the control actuator which would result in adjustments to the cooker settings. This in turn altered the cooker's temperature. When fed back through the visual recptor devices on through to the central processing unit, this produced the feedback loop which had been dictated in those early design sessions by Process Boundary Analysis®.

So, how did it work?
