Having been inspired by this Blinky Tape blog post by the FT engineering team I thought I’d try to use mine to display some useful information. In this case how the trains and tube are running. So I’ve come up with a couple of python scripts (tested on a Raspberry Pi B+ but should work on other systems if you change the serial port name from /dev/ttyACM0).
The tube line status indicator uses the fantastic TfL API to get the standard set of statuses (underground, overground, wombling DLR) and displays them with official colours on the tape. The LEDs are static if normal service is occurring and flash if there is any disruption…
The main line trains indicator uses my Huxley project to access the National Rail live departure boards. Some calculations are performed and if there is disruption to the configured route or trains then the tape gently throbs red…
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
