I’ve just noticed that The Pi Hut has just put on sale the Google AIY Voice Kit. This kit, which is the offspring of the famous MagPi issue 57, costs £25 and contains everything you need to put together your own artificial intelligence box, except the Raspberry Pi itself.
Instead of The MagPi issue, it comes with a special book (from the ‘Essentials’ range, pictured below) with the instructions necessary for assembly and operation. By my reckoning, and from a quick survey of the other resellers, The Pi Hut is the first to offer this kit for sale, so get yourself over there whilst stocks last! If you need the Raspberry Pi as well, get one from The Pi Hut at the same time to save postage!
