The recent Notre-Dame Cathedral fire in Paris was devastating, but work is now well underway for a complete reconstruction. Over a billion Euros have been pledged for the rebuild, and 40 teams of workers under the watchful eyes of 4 lead architects are now on-site. But as fighting over how much to modernize rages on even during construction, much attention is being paid to the famed acoustics of the structure.
Luckily, a full study of the Cathedral’s acoustic imprint was done in 2013 by Brian FG Katz, a Fellow of the Acoustical Society of America and CNRS research director at Sorbonne Université. The hope is that the details from that work will guide construction methods and materials selection in order to restore Notre-Dame to its previous acoustic glory.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
