# Badger2040, Apple Macintosh 1984
## Overview
This is a custom UI for Badger 2040 that I built for the Census
engineering offsite in 2022. I aimed to recreate the iconic 1984
Macintosh UI in a compact design.
## Known bugs
I had to cut some corners, so that I could finish the assembly of a small batch
before the event. Here is a list of known bugs:
- If you open the same application twice (e.g. open QR app, open Badge
app, and open QR app again), the device will restart and show a
welcome screen. I shouldn't have tried to build a multi app
experience in the first place. IMO, it is too much to do to
implement this right in Python. I think if it was Lisp environment,
it would have been easier.
- I forgot to adjust the battery voltage to calculate the battery
level. The device may show that a battery is empty or it is not
plugged in.
## Upload steps
- Upload pimonori-badger2040-micropython bootloader
- Upload Python scripts
## Edit text
- Badge: badges/badge.txt
- QR: qrcodes/qrcode.txt
- Clippy: fortune/cookie.txt
## Edit images
1. Clone https://github.com/pimoroni/pimoroni-pico
2. `python3 examples/badger2040/image_converter/convert.py --binary image.png image.bin`
3. cp image.bin badges/badge.bin
## User Guide
- A button opens Badge app
- B button opens QR app
- C button opens Special app. Up/Down buttons randomly load a new
quote
- A + C buttons open Welcome screen
