Hello,
First off I'd like to say I enjoy your show greatly, and it inspires me to design/build my own projects. The small error that I would like to cite, is that you refer to the microcontrollers in your build as microprocessors. Although this is a minor error I feel it should be addressed. A microprocessor is a CPU or brain and they can be purchased. Microcontrollers are somewhat complete mini-computers. Microcontroller chips such as the parallax propeller series, PICs, and Atmel series of chips used with the arduino environment, are all able to access the built in microprocessors to handle the code programmed onto the on chip memory. This code can then be transformed into the ability to use the other prehiperals on the chip such as extra memory, oscillators, timers, signal drivers, and logic gates. These prehiperals are what allows the microcontroller to act like a small computer, and many microcontrollers contain multiple microprocessors to allow for more actions to happen at once. Again it is a small error in naming but should be noted.
