Microsoft Reactor

Microsoft Reactor Part 1Microsoft Reactor Part 2
AI is no longer stuck in the cloud. Instead of relying on powerful computers with GPUs, the past few years has brought AI to small devices thanks to TinyML – machine learning models that can run on microcontrollers. You may already have devices that use this around you, from voice controlled smart speakers to fitness trackers.
In this 2-part show, Jim gets his hands dirty with TinyML, building out a fitness tracker that can distinguish between rowing and running using a small microcontroller from Seeed studios – the Seeed XIAO BLE. Training and deploying these models is super complicated, so Jim enlists help from Edge Impulse, an online tool for capturing training data and building TinyML models.
Once Jim has his model, he will deploy it to his device using VS Code and PlatformIO, an extension for VS Code to do microcontroller development. From there he’ll deal with one of the complexities of building low powered fitness trackers, connectivity. A lot of fitness trackers use Bluetooth to sync with a phone app, so Jim will take this route, syncing fitness data to Azure IoT Central from a mobile app.
