You've probably been there; Late one night in the pub, after a few too many beers, you have a bloody fantastic idea. A revolutionary idea. An idea that's going to change the world. The chances are that come the morning you’ll realise that your beer-addled brain had slightly overstated your own awesomeness, but sometimes (just sometimes!) the spark is there. The sparks of my idea began to fly about five years ago before, eventually, they caught light. Today, I'm waiting for a factory in China to start manufacturing something I invented -- the Triggertrap, an Arduino-based open-source universal camera trigger.
