Designing the Machine Learning board on the EDGE… BRAINCRAFT! @tensorflow @adafruit #machinelearning #tinyML

The idea (video) behind the upcoming BRAINCRAFT board (stand-alone, and Pi “hat”) is that you’d be able to “craft brains” for Machine Learning on the EDGE, with Microcontrollers & Microcomputers. On ASK AN ENGINEER, our founder & engineer chatted with Pete Warden, the technical lead of the mobile, embedded TensorFlow Group on Google’s Brain team about what would be ideal for a board like this. What did we come up with? Here is a start!

Inputs:

  • Loads of sensors!
  • More sensors can be connected via plug-n-play stemmaQT
  • Image sensors, like a camera, or ‘image sensors’ like the Panasonic Grid-EYE. Heat-Sensitive cameras can be used as a person detector, even in the dark!
  • Microphone, voice detection for powering on/off
  • Accelerometer for gestures, vibration sensing. Could be useful for machinery/industrial predictive maintenance.

Outputs:

  • Screen display for debugging
  • Speaker for audio feedback as to what is going on.
  • Relay control to turn things on/off, etc. and/or other actuators.

Connectivity:

  • NB / Narrowband IoT? Wireless flexibility: WiFi, cellular, Bluetooth LE
  • Works with adafruit.io, of course!

Power:

  • Battery powered / low-power.
  • Solar add-ons or energy harvesting. Make OK with lots of power sources that are not reliable.
  • On/Off switch!

The name BrainCraft came from a company I worked at in the late 90’s that was acquired, around that time, I went off to Fallon, BrainCraft.com and everything about it, eventually went away, so I picked up the domain name about 10 years ago and have been using it for crafty projects, and now, finally, machine learning hardware. It’s kinda cool it all worked out, including have AI in the name, as well as craft and brain, since that’s how I think the training of models works for machine learning, it’s way more “craft” at the moment.


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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.

  1. There are a couple of thermal sensors that use I2C that you might wish to support out of the box, for example the Melexsis which has higher res than the grid-eye -> https://shop.pimoroni.com/products/mlx90640-thermal-camera-breakout?variant=12536948654163

    Also for imaging I imagine many people will want to use the raspi camera, so integration with it should be made straightforward as possible.

    All the best, and keep up the great work!

  2. LoRa wan chipset, for europe 868MHz, like the RFM95 breakoutboard https://www.adafruit.com/product/3072
