Here is an Amazon list of all the parts needed for a Hello Drinkbot, except wire and the laser-cut frame.

Here is an Amazon Idea List as well.

Here is a Google Sheet with the Bill of Materials broken out on a per-bot basis.

Notes on the Touch Screen

The BOM includes a 7" touch screen as an example. I have tried doing some prototype cases, but so far I don’t have a case which lets you cleanly mount the touchscreen. Also, if you go with the touch screen or an external monitor, you may also want a keyboard. I have this wireless keyboard — it includes a trackpad and has worked well so far.
