Show HN: Web controlled traffic light for Raspberry Pi powered by Elixir/Nerves
- fabrik42 6y agoThis traffic light project exists roughly since 2011. I use this side project as a form of recreational programming and joyful overengineering. The software/hardware project has seen many stages over the years, I tried to sum them up here (taken from the Readme): * Wired up to my Mac controlled by a weird combination of Kernel extensions and Java code. * Connected to a Synology NAS with a self-soldered Velleman K8055 USB experimentation board. * Connected to a Raspberry PI, running a Ruby script locally, node.js on the server side. * Wiring mostly replaced by a custom etched circuit board - a Raspberry shield built only for the purpose of changing the traffic light (and debugging it at home without disassembling the whole traffic light). * Replacement of the Raspbian/Ruby client with Elixir and Nerves. * Replacement of the node.js server with Elixir and Phoenix. Happy for any feedback!
