Book Recommendation: Calm Technology: Designing for Billions of Devices

Amber Case’s book “Calm Technology” could be required reading for hardware developers one day. It is packed with suggestions for building #IoT gadgets that will be pleasing to use. Her book focuses on how alerts should smoothly capture the users attention without creating excessive disruptions. We have come from a world of a single PC which received all of our attention and now must develop less invasive indicators and alerts that stay in the periphery. Amber suggests coding simple systems in low level languages that are stable with manual override redundancy in case the network connection should go down.

Bringing the next 50 billion devices on-line will be a challenge. The analysts at Gartner group have forecasted that 25 billion devices will be connected by 2020. There is another estimate from GE that by 2020 the convergence of machines, data and analytics will create a market that exceeds $200 billion globally.


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
