Use Diasend to Upload and View Blood Glucose Data

Biohackers have been enjoying the convenience of continuous blood glucose monitors for the last few years. Being able to see how food and exercise effect our blood glucose provides insight into lifestyle changes that we can make to improve ourselves. The FreeStyle Libre CGM costs less than $300, but it has some three issues that need to be worked around to make it useful:

  • Abbott does not sell the FreeStyle Libre in the US so it must be bought on-line from another country
  • The FreeStyle Libre if bought outside the UK or AU will be in another language. I run mine in Italian as there is no English option.
  • Abbott’s Auto-Assist currently does not sync data with MacOS Sierra.

The first two issues are easy enough to work around, but having data to review in a friendly graphed form would make things so much easier. Enter Diasend, the utility that was designed to pull data from various glucose monitors, upload it to the cloud and provide a friendly web / phone app interface for viewing. Diasend is a free utility and service. Simply create a account, download the ‘Diasend Uploader’ and plug in your glucose device to your laptop to sync.

I’ve especially enjoyed using the Diasend iOS app for reviewing data. I can actually eat a significant amount of carbohydrates (50-100g) per day as long as they are in the form of starchy vegetables and nuts. Faster carbs like ginger beer brought my blood sugar up to 138 mg/dL. In second place was half a plantain which would peak at about 116 mg/dL. Now I can briefly eliminate these two foods while I look for other spikers.


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.
