Google made their AIY projects kit available to the Pi users for free through the MagPi Magazine Issue 57. However, since then, there has been no word yet on the retail availability of the kit. So to help out the ones without the kit and as a contribution to the Pi community, I have come up with this DIY Voice HAT.
The HAT is created using the same components found on the original AIY Projects Kit Voice HAT. By, writing the same device tree, the DIY Custom Voice Hat can be used as an alternative to the original Google Voice HAT.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
