Something I really miss living in a big city (Paris) is that I almost never get to see the stars anymore. Some of my best memories in university were going out for walks at 3AM and just laying around in a field, looking up at the stars and being humbled by a sense of awe at the scale of ‘everything out there’. Chris Gammell posted a link to scaleoftheuniverse.com on twitter, and when I had a look it reminded me exactly what’s so amazing about the world we live in, and everything around, in, and above us. Great to be reminded to look up … and down … from time to time.
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.
Have an amazing project to share? The Electronics Show and Tell with Google Hangouts On-Air is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

Marty: While I was all of two years old when that was made, it’s definately a classic. Thanks for the heads up on the link.
The screenshot shows micrometer but uses the abbreviated form of picometer (pm), what’s going on there?
