Your Subway Was Delayed by 1930s Signals. A Fix Is Finally Coming.
While I love movies from 1930s New York, I’m not a huge fan of 1930s NYC subway signal systems. Time to upgrade the OS. Via The New York Times.
New Yorkers have grown unhappily accustomed to hearing that their trains are delayed by “signal problems.” But most riders probably have no idea what that means.
The signal system is the invisible, unglamorous backbone of the subway, controlling when trains can move down the tracks. But the demands of a 21st-century ridership are being borne by archaic signal equipment, some of which dates to when Franklin D. Roosevelt was president.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
