I've been hanging around at political gatherings, and I've noticed that nametags are getting a LOT of use. There's a whole semantic language built up around what kind of nametag you have, and what it says. Many committee people have made themselves engraved plastic name tags, which is the politics equivalent of showing up at the pool hall with your own screw-together rock maple pool cue in a hard-sided box.
So I am noodling around with an eInk display for a nametag.
What if your nametag was geofenced, so it showed different stuff depending on where you are? What if it showed an augmented reality tag that would allow a camera taking a picture of you to augment your nametag with stuff? What if you could update your nametag with a command to a Slack bot? What if your nametag could easily display a QRcode for your LinkedIn profile, your Facebook Messenger code, your Snapcode, your Venmo account, etc, etc?
What if your nametag could change to a plausible variant spelling of your name every twenty seconds, just to be a jerk?
That's what I'm playing around with in here.
Images for display on the PaPiRus 2.0" screen should be 200x96px and must be 1 bitmap file saved with the .bmp extension.
Some example images can be found in the bmp/ folder.
The PaPiRus HAT consists of a driver board, a small eInk display, and some software that lives on the Pi.
Once set up, updating the display can be done on the Pi's command line:
To print some text to the display:
$ papirus-write "Hello, my name is\n SAM HANDWICH"To draw an image on the display:
$ papirus-draw /path/to/file.bmp- PaPiRus: documentation for the PaPiRus ePaper HAT for Raspberry Pi made and sold by Pi Supply.
