See When Your Train is Late With LED Lights and Raspberry Pi

By Kate Knibbs on at

At this point, there are tonnes of apps that let us know when our trains are running late. But apps aren’t nearly as pretty as an LED light strip set up to blink when something’s wrong with your commute.

London-based developer James Singleton used a Raspberry Pi B+ and the London Underground’s API to turn a Blinky Tape LED strip into a combination light decoration/train delay notification system.

Blinky Tape lets you customise the colours on your LED strip, so Singleton colour-coded his to correspond to the colours of the Tube.

Singleton published the code he used for the project on Github. And even though it’s London-specific, any train system that has an API like London’s could be measured in this way.
