I built a device to show the departure time of trams at the end of my street, to avoid walking to the stop too soon, and having to stand in subzero temperatures for too long.
(I live in Helsinki, and it was the end of last year when I put this together. Temperatures were colder than -20C for a week or two.)
- opayen 9y agoCould you give more details about it? What device is it? How does it work?
- stevekemp 9y agoI remember posting about it here in the past, because I was so in love with the service that allowed me - a complete beginner - to get a case 3d-printed cheaply and easily. The project itself is documented here: https://steve.fi/Hardware/helsinki-tram-times/ https://steve.fi/Hardware/helsinki-tram-times/ It consists of an LCD-screen and an ESP8266 device. (Think "like an arduino, but with on-board wifi". Programmed in C++ it basically polls an online URL to decide what to display with a simple web interface you can point your browser at to change the timezone, the stop-id being monitored, etc.
