Posts Tagged ‘PiFace’

I was asked recently by our mechanical team at work to help them with a little project that involved building a pneumatic test rig to stress test our product. It was designed to do things like electrical stress tests like powering the device on and off a million times, mechanical tests like plugging and unplugging a USB cable and touching the touch screen. They had me a pneumatic.

The rig is powered by a raspberry pi with a PiFace for the relays and I/O. The interface is written in Node.JS with Angular for the frontend. It was a really great project (simple as it may be) and has been a great excuse to dive into node properly. It’s power continues to astound me and Angular’s bidirectional bindings really makes it easy to give powerful embedded projects a UI. It scales up really well to so you don’t have to worry about changing technologies later. The code is available on my github as usual.

I know this video is not very exciting but I think it’s cool. I’m also working on getting the low level SPI bindings working properly. More on that in a future post but node-gyp is incredible and node-ffi┬áis so incredibly powerful for quick external library bindings.
