The idea is that we can automate tracking of the consumable items that we periodically need to replace at DoES.

The process is something like this:

• we create a QR code and put it on or near an item which we will run out of (coffee, crisps etc.)

• the QR code points to tr.im/1bRyy?item=$THING, where $THING is a short description of the thing to buy or a bar code number

• this tr.im service redirects to a node-red flow I have set up to create an issue in this DoES things-to-buy repository.

• a DoeS organisers/contributors can subscribe to issue creation notifications and choose to take ownership of the issue indicating they will purchase on the next trip.

• after replacing the needed item the issue can then be closed.

You can create a QR code for editing, e.g. with Inkscape using a node-red flow here

Where $THING is the thing that needs to be bought.

Alternatively you can use the QR Codifier application installed on DoES Sophia PC or available here
