Welcome to the coffee image sharer. When you've poured yourself a delicious drink of coffee and perhaps created an intricate image in the foam on top, isn't it a shame to drink it without sharing it's beauty with the world (or at least a friend)? This project rectifies this.

Pop your coffee (or an item of your choice) in front of the rater and press the button. It'll upload the image to the Adafruit.io platform. The device will light up green once it's successfully uploaded a photo.

Another device will then flash up an image of your coffee and give the other user the opportunity to press red (if they like it) or blue (if they think you could try harder). The feedback will be uploaded to Adafruit.io and sent back to your machine. The LEDs will turn red or blue, depending on their choice. 

Both devices are identical, so either one of you can send images for approval to the other one.

There are quite a few parts because you'll build two of them. One for you and one for a friend.

You'll need two of each of the following:

Parts

One of the following:

You'll also need access to a 3D printer and some 3D printer filament to produce the holder. You could also build this in a different way. It wouldn't be too difficult to make something out of wood with hand tools that does the job while looking grand.

For setup, you'll also need the following, if you don't already have them:

You'll also need 16 m2.5 machine screws and nuts.

During setup, you'll use a keyboard, mouse and monitor, but these won't be needed once the project is up and running.
