There’s a fine line between solving problems that don’t exist and solving problems that no one recognizes until a solution is found. The former shows up with housewares peddled on late-night infomercials, while the latter is summed up by [Henry Ford], “If I asked people what they wanted, they would have said faster horses.” [Dave]’s method of storing microcontroller code in the cloud definitely falls into the ‘useful’ category.
[Dave] first realized the problem when he was digging around the IDEO Toy Lab and came across an orphan project, a Barbie credit card swiper. [Dave] had no idea if the firmware for this project was saved on the server, or even if the current version was available. One solution to this problem could be burning a copy of the source onto the Flash or EEPROM on the board.
There’s a problem with this idea, though: storing the source in an Arduino’s memory takes space. Thinking laterally, [Dave] realized that editing source happens on a computer, computers are connected to the Internet, so why not keep the source “in the cloud?”
[Dave]’s solution is to host the source on GitHub, and tie every piece of code to a board’s unique USB serial number. This gives every Arduno a unique ID, allows for version control, and libraries of multiple files.
