badgie

This is some code for the e-ink badges for the open day that can be adapted to suit.

The badges have three modes, as follows -

mode a (button A) - this mode cycles through 3 types of display at random -
- BOFH - quotes from the BOFH series stored in texts/bofh-excuses.txt
- images - files in the images directory
- epigrams - witty(for a given value of witty) sayings stored in texts/epigrams.txt
mode b (button B) - this mode just displays the persons name, role and School alongside a QR code or the Coventry Pheonix
mode c (button C) - this mode displays either the same as the QR version of mode b, or the persons name plus a message which comes from texts/mess.txt

For modes a and c, the image will change after a certain number of seconds (defined by speed * SPEED_MULTIPLIER)

The up and down buttons will either toggle between the QR code and the Pheonix (mode b) or change the value of speed and hence how quickly the badge displays something new (modes a and c)

Getting started

Follow the instructions on the pimoroni badger page to get the environment set up.
Copy these files to the badge-
- badgie.py
- battery.pi
- boot.py
- main.py
- simplybadge.py
- pheonix.bin
- qr.bin
- person.txt
Create the following directories on the top level of the badge -
- images
- texts
Copy the files in the images directory on the computer to the images directory on the badge
Copy the files in the texts directory on the computer to the texts directory on the badge
Run main.py to test to make sure everything is working.

Configuring the badge

The main things that you'll want to configure is your name, etc. and this is stored in the file person.txt. This file is four lines long, with the following structure, each on it's own line -

Your name
First line of the School name
Second line of the School name
Your role

You'll probably also want to create your own QR code. Whilest you can put a VCARD in a QR code, the chances of it displaying properly on the badge are remote. The best thing to do is to link the QR code to an online VCARD or a website with your contact details (e.g. your Pure profile) and code the URL of that site into the QR code. To do this -

edit the file vCard-QR.py and generate the QR code (this should be done on the PC, not on the badge)
Open the file generated (qr.png) in your favourite image editor (e.g. Gimp) and
- reduce the image to 1 bit
- scale the image to 104x104
- enlarge the canvas (NOT the image) to 104x128 and centre the image on the canvas
- save that image
Run the convert.py programme (on your PC) with the image -
```
 convert.py --binary qr.png
```
Upload the resultant file, qr.bin to the top level of the badge (do NOT load it into the images directory)

Other files

battery.py - gives the current state of the battery
conway.py - Conway's game of life from the Badger demos
simplebadge.py - a static badge which is the QR version of mode b. This saves the battery going down, so it's a good "sleep" type mode.
