On December 3rd, you will find SparkFun CTO Kirk Benell and Creative Technologist Rob Reynolds at the AIoT Dev Summit! In collaboration with Ambiq Micro and TensorFlow, we are going to be running a hands-on workshop where you will be able to build your very own Harry Potter wand! That's right, all of us muggles out there can finally get a magic wand without ever having to break into Ollivanders like a certain dark wizard.

AIoT Dev Summit

This is an experiential and experimental workshop that focuses on the use of TensorFlow Lite on a low-power microcontroller to perform machine learning. Modalities covered include word recognition in speech, gesture recognition using accelerometer values, and human presence detection using imagery.

The workshop will cover machine learning model training, deployment and operation, with a majority of time spent on a gesture-recognition activity - “Magic Wand” - that is based on the content of Pete Warden’s forthcoming book, TinyML: Machine Learning with TensorFlow on Arduino and Ultra-Low-Power Microcontrollers.

All example applications will use the SparkFun Edge Dev Board, which integrates Ambiq Micro’s Apollo3 Blue Arm Cortex-M4F microcontroller, microphones, camera access and on-board low-power management, to deliver a complete package spec’d to run TensorFlow Lite using only 6uA/Mhz. The SparkFun Edge board can run solely on a CR2032 coin cell battery for up to 10 days.

Join Us for the Workshop!

If you can make it, the AIoT Dev Summit is open to everyone - if you register before November 17th you will get a discounted ticket. The conference pulls AI, IoT, and robotic experts for hands-on tech workshops and educational keynotes. Speakers include Simon Segars, CEO of Arm, Mark Spates, Product Lead at Google, Chris Anderson, CEO of 3D Robotics and Massimo Banzi, Co-founder of Arduino. All sessions will be at the Computer History Museum in Mountain View, CA on December 2-3, 2019. Hackster just released a helpful conference overview, here.
