Stuart Harrison has a young son whose school awards (good behaviour) reward points and (bad) behaviour points. Frustrated with the school’s interface, Stuart set-up a screen scraper to get the data off their system and put it onto his own system. After a while, he realised that their method of points was flawed, at least in regards to how it awarded them with respect to his son. So, he decided to build his own reward system using a couple of Amazon Dash buttons and a Raspberry Pi 3. Programmed with a combination of Ruby and Node, the system runs on a 5″ display with the Dash buttons alongside which add points on. Ingenious, and highly effective according to Stuart. You can read about how he did it, and see the code, over on his blog.
