Karl Lunts Embedded Robots

"This site contains lots of embedded control and robotics projects that I've developed over the years. Many were featured in past articles in Nuts & Volts magazine, and in my book, Build Your Own Robot! Others were projects that I've shown at various meetings of the Seattle Robotics Society (SRS). And I offer here many powerful tools that I've created for working with the Motorola 68hc11 and 68hc12 microcontrollers." - Karl Lunt

Forrest Mim's Science Web site

Mims was interested in science at an early age, and he built an analog computer as a high school science fair project in 1960. While memorizing his Latin class vocabulary words, Mims conceived a computer that could translate twenty words from one language to another.

Forrest M. Mims III is an American amateur scientist

The input was six potentiometers (variable resistors) each having a dial with 26 letters. Entering the first six letters of the word on the potentiometers set a total electrical resistance. The memory of known words was a bank of 20 screwdriver-adjustable trimmer resistors.
