If you are an Arduino fan, then you most likely heard about this one. Arduino and Gameduino work in tandem to track up to 750 satellites at once. It displays the data on a screen similar to something out of a 1980's modern war film. Fitting so, the underlining tracking portion is based on the 1983 PLAN 13 algorithms, written by James Miller. (PLAN 13 is a 6270 line program available here.) The whole front/back end is written into 37KBps of user memory. Satellite is retained in the onboard 128KB EEPROM. The setup is designed by Pixar Animation Studio's Technical Director Mark VandeWettering, aka Brainwagon.
The project is named ANGST, The Arduino n' Gameduinio Satellite Tracker. VandeWettering plans of releasing the source code and schematics on github. I am mainly posting this to give a link to the files. As said in the video, someone else is planning to expand on the concept with tracking antenna hardware. I am hoping to see some thoughts and dev coming from the community.
When does an Arduino project become a sellable product?
