LCD display showing blood sugar level
Made a little hack to show my blood sugar levels on a portable LCD display ( #m5stickC ) using libre2 sensor and their undocumented API #esp32 #diabetes #libre2 -

Of course the #pocketspectrometer can be used without the web interafce with its own UI enabled by its own screen and two buttons on the #M5stickC. Here is the link to the github repo github.com/devpnryn/Poc...
Pocket spectrometer in comparison is only slightly larger than the cuvette itself
Look at the pocket spectrometer to appreciate how small it is
Connect AMS sensor with Grove-to-Stemma cable
These are all the components required to build the pocket spectrometer
2/6 The biggest upgrade is simplified assembly with plug-and-play connections! V2 uses
@adafruit.com's #AS7341 sensor with built-in Stemma QT connector, eliminating all soldering. Connect it to the #M5StickC with a Grove-to-Stemma cable and you're ready to go! #DIY #CitizenScience
2/6 Why #M5StickC? Built-in screen & buttons, tiny size (48x25x13mm), #I2C port, & runs #MicroPython. Plus its price makes the spectrometer affordable! Plus, no external device is required for simple spectrometer tasks.
1/6 🧵 I'm building what might be the smallest #opensource #spectrometer with an easy to use UI! I call it a pocket spectrometer. Combining #M5StickC (~$20) with AS7341 sensor (~$16). My goal? A complete spectrometer that is barely larger than a sample cuvette itself.
以前、キッチンタイマーが壊れたときに余り物で作った代用品。ソースコードを見つけたので整理してgithubへ。最近はM5Unifiedのおかげで大分楽になってる。
MiniEncoderHATのロータリーノブ1ノッチで、進角が2で出力されたり、1で出力されたり安定しないのはHATのファームのバグか？
