Blue Point Engineering - Animatronics Robotics
"..Product line of low cost, high quality, hardware, electronics, and supplies used in animatronics, robotics, haunted Industry and technology education for both the hobbyist and professional designers, imagineers and dreamers creating their own forms of animatronic and robotic life."
The DMX- (Servo) Motor controller allows DC motors to be controlled over a standard DMX system. The board may be configure to drive the DC motor simply as a variable speed, reversible motor or with the addition of a position feed back potentiometer, to create a powerful servo motor controller for accurate positioning purposes.

"The mission here is to help hobbyist get started with microcontrollers. The primary focus is ARM7 based microcontrollers which can be a big step for persons new to embedded development."
The chip is very easy to work with and provides 12 or 16 I/O pins with various built in functions like variable flash rate, event counters, variable sink current and more. They provide lots of documentation and a DLL to make interfacing easy."

Guglielmo Marconi, an Italian electrical engineer, transmitted the first wireless signal in 1895. By the turn of the century he had formed telegraph companies in England and opened the first wireless office in New York City. In 1901, Marconi telegraphed the letter "S" across the Atlantic Ocean. The U.S. Navy was so impressed that it replaced a flock of carrier pigeons with the "wireless" for ship-to-shore communications.
Two years after inventing the phonograph, Edison brought the world the incandescent light bulb. Thirteen years later, his start-up electric company would merge with the Thomson-Houston Electric Company and be renamed General Electric.
In 1929, RCA purchased the Victor Talking Machine Company, then the world's largest manufacturer of phonographs (including the famous "Victrola") and phonograph records. This included a majority ownership of the Victor Company of Japan, or JVC. The new subsidiary then became RCA-Victor. With Victor, RCA acquired New World rights to the Nipper trademark. This Trademark is also the trademark for the British music & entertainment company HMV who now display nipper in silhouette.
In the early 1920s, David Sarnoff publicly speculated on the possibility of "every farmhouse equipped not only with a sound-receiving device but with a screen that would mirror the sights of life." The idea of television was not new, and mechanical systems had demonstrated crude pictures. But it was Sarnoff's historic meeting with engineer Vladimir Zworykin that set the stage for RCA's success at electronic television transmission and reception.

Chipdir - Database of ICs by Jaap van Ganswijk
Why use the 8085 one might ask. Well it's a straight and simple traditional 8-bits processor with hardly any strange quirks, except perhaps that the data bus is combined with the lower part of the address bus to save pins. This trick is often used and you only need a one way latch to keep the address stable while the bus is used for data in the second halve of the memory cycle.
A real-world 8085 project
The 8080 and even the later 8086/8088 need two 82xx series support chips, whereas the 8085 can work on it's on (except for the latch).
The completed 8085a unit along with the power supply that Lewis built and a 7-segment display unit. The photo shows the computer in operation.
Interfacing with digital circuitry, analog circuitry, serial circuitry (UART and SPI), servo motors, and buzzers, etc., all become trivial single-line, single-minute tasks in StickOS BASIC, so the user can concentrate on achieving the control task at hand, rather than the detailed mechanics of control."
Embedded Systems Made Easy - StickOS
- Rich Testardi (mail) 2009
"StickOS BASIC is an entirely MCU-resident interactive programming environment, which includes an easy-to-use editor, transparent line-by-line compiler, interactive debugger, performance profiler, and flash filesystem, all controlled thru an interactive command-line user interface....
CPUStick is a 1"x4" very low cost standalone USB embedded computer based on the Freescale MCF52252 ColdFire MCU and MC13201 ZigFlea Wireless Transceiver,..."
StickOS Examples - A simple embedded system, like a toaster oven temperature profile controller, can be brought online in record time!
LCD Digital Thermometer - With the advent of advanced serial peripherals based on the I2C or QSPI serial interfaces, embedded systems can take on a whole new level of real-world functionality! An LCD digital thermometer, displaying both Celsius and Fahrenheit, can be brought online in minutes, with just a quick study of the I2C peripheral register or protocol definitions!
