[James] is a frequent user of the London Underground, a subway system that is not immune to breakdowns and delays. He wanted a way to easily tell if any of the trains were being disrupted, and thanks to some LEDs, he now has that information available at a glance without having to check a webpage first.
Inspired by the Blinky Tape project at FT Engineering, [James] thought he could use the same strip of addressable LEDs to display information about the tube. A Raspberry Pi B+ gathers data from the London Underground’s TfL API and does a few calculations on the data. If there is a delay, the LEDs in the corresponding section of the strip will pulse, alerting the user to a problem with just a passing glance.
The project is one of many that displays data about the conditions you’ll find when you step outside the house, without having to look at a computer or smartphone. We recently featured an artistic lamp which displays weather forecasts for 12 hours into the future, and there was an umbrella stand which did the same thing. A lot is possible with LEDs and a good API!

Pictured above is a functioning model of an automated underground parking structure which was built and used, but obviously it never caught on widely. That makes us a bit sad, as it removes the need to find an empty parking spot every time you use the garage; and having a robot park your car for you seems very future-y.
The gist of the ROTOPARK system is a carousel and elevator system for parking cars. just drive into a single-stall garage at ground level, take your ticket, and walk out the people-hole. The garage stall floor is a sled which moves down an elevator (shown as blue stalls on the left half of the image) to be stored away in the rotating carousels of cars.
Obviously mechanical failure is a huge issue here. What if the elevator breaks? Also, at times of high traffic we think getting your vehicle back out of the system would be quite a bit slower than the “static” parking garages we’re used to. Oh well, maybe some day. Check out the classic marketing video after the break which shows off the concept, construction, and use of the system.
