I have already built the original AIY Voice kit – and now I just discovered the AIY vision kit.

For those that have not seen any of the AIY kits – the ones I use are cardboard (!) kits built around Raspberry PI’s, running Google software, and the original was a simple version of Google Home, but with source code to be modified by anyone.

This is the vision kit :

and in this case you will find a Raspberry Pi Zero W inside, the smallest and cheapest Raspberry Pi, so the cost is kept really low. 
On top of this it runs Tensorflow!
