However, since the keyboard has a localhost REST API and so does my blood sugar, I busted out this silly little shell script. Add a cron job and my keyboard can turn from orange (low), to green, yellow, red (high) as my sugar changes. That provides a nice ambient notifier of how my sugars are doing.

Diabetics need to manage our sugars at the least hour by hour and sometimes minute by minute. As such it’s super important that we have “glanceable displays.” That means anything at all that gives me a sense (a sixth sense, if you will) of how I’m doing.

If you’re a Type 1 Diabetic using a CGM – a continuous glucose meter – you’ll want to set up Nightscout so you can have a REST API for your sugar. The CGM checks my blood sugar every 5 minutes, it hops via BLE over to my phone and then to the cloud. You’ll want your sugars stored in cloud storage that YOU control. CGM vendors have their own cloud , but we can easily bridge over to a MongoDB database.



Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote

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.
