When Kelenföld Power Plant [Hungary] started generating electricity in 1914, it was one of the most advanced plants of its day—though it was modernized and expanded several times since then to serve the changing energy demands of the surrounding districts.
The outdated section of the power plant, which is showcased below, isn’t completely abandoned since it’s in private ownership these days. But the two main attractions—the legendary control room and the old transformer house—are closed to the public, despite the fact that both are considered masterpieces of early 20th century industrial design. You can only visit them during one of the rare guided tours organized by enthusiastic non-governmental organizations, only a few times a year.

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.
