Here’s a weather instrument – the Dodecahedral Barometer – that can actually determine how tall you are by reading the barometric pressure between your head and your feet. Mark Thoren notes that his gadget was inspired by the release of some new electronic products. The first is a Serta model 270 barometric pressure sensor that recently came on the market. The sensor is inexpensive and accurate to the point of being suitable for weather stations. The other items that make this gadget possible are some new HP displays that make the gadget’s readings visually appealing.
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.
