Solving Rubik's Cube with #RaspberryPi, #Lego and #Python...

Sequencing your Home #IoT Lights... So that others think you're at home... Gets really sophisticated!

...So why am I doing this? I used to teach Arduino / Embedded C... Which led to C pointer issues. For newbies it's best to start with a safer language like #RustLang... Save them the frustration of crashing pointers 😉 Now I'm creating Visual Rust to help newbies understand Rust syntax via drag-n-drop

Interesting new geometric shape for #KiwiFruit...

Experimenting with App State for Visual @PineTime Apps @PINE64 ... Do YOU understand this Visual Program? 🤔 (Ignore the #RustLang code)

Current state of #Haskell...

#Haskell gets easier on #VSCode...

#RustLang for Jupyter Notebooks... By Google!

Running Android adb on #UbuntuTouch... So that's how #PinePhone @PINE64 will work... So cool!

Why do I love #OpenStreetMap? Because I have done awesome #IoT projects with OpenStreetMap + #Mapbox... Like this 3D map! https://youtu.be/BLfAq1FzUbs

So glad I aced A-Level Computing (and the Special Paper too)...

I'm targeting the open-source Apache #NimBLE Stack, which runs on #ZephyrIoT, #RIOT_OS and #Mynewt OS. Here's my problem statement... There must be an easier way to code #BluetoothMesh! https://gist.github.com/lupyuen/0db460687b5aea48885ab7859fda17cc

Particle Mesh died today... It's true, Mesh Networks are very hard to code! Anyone keen to join me in creating #RustLang Bindings for #BluetoothMesh Models? Maybe even a Domain-Specific Language? https://medium.com/@ly.lee/bluetooth-mesh-with-nrf52-and-apache-mynewt-44823407c471?source=friends_link&sk=ac433fa04e13f75985927c37db1e2b10

How I fell in ❤️ with #STM32 Blue Pill and Real-Time Operating Systems (Apache #Mynewt #RTOS) one year ago... Featuring Moon Base One 😀 https://medium.com/@ly.lee/create-your-iot-gadget-with-apache-mynewt-and-stm32-blue-pill-d689b3ca725?source=friends_link&sk=d511426d5a2217ebd06789b3eef7df54
