The goal of this article is to explain how to install one or many Raspberry Pi 3 B+ devices connected with one to four Raspberry Pi Zero 1.3 devices each via USB OTG networking.

Preview

Each device - Pi and Zero - will be connected to the network 192.168.0.0/24. Each Zero will be connected via USB OTG to the Pi. That will establish a network between the two devices. On each Pi a network bridge will be configured to forward the traffic between the Pi ethernet port and the connected USB ports.

Their individual hostname/IP pattern will be:

10.lab | 192.168.0.10 (1st Pi)
20.lab | 192.168.0.20 (2nd Pi)

# Make an RP2040 in BOOTSEL mode writable by all users, so you can `picotool`
# without `sudo`. 
SUBSYSTEM=="usb", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0003", MODE="0666"

# Symlink an RP2040 running MicroPython from /dev/pico.
#
# Then you can `mpr connect $(realpath /dev/pico)`.

Unknown username "whoopsie" in message bus configuration file (Crouton)
For some time I had this notification "Unknown username 'whoopsie' in message bus configuration file" coming up when I started my Ubuntu-server on my Chromebook via crouton. It seemed not to do anything wrong but hey, I hate to see error messages popping up on the screen and not knowing what it really means.

In my search I've learned that the user 'whoopsie'  is being used for the error reporting daemon in Ubuntu.

System Description:
Toshiba Chromebook 2:
Intel® Celeron® Processor N2840
Intel® HD Graphics
4GB DDR3 1600MHz

• Dactyl & Dactyl Manuform Case Preparation

• Both part needs to have ProMicro MicroController so It can use the QMK Firmware for controling the keys on keyboard itself

• 4x6 is the way to go

There’s a strong trend for ergonomic keyboards to reduce the number of keys, mostly becouse of QMK framework that allows layering. People usually prefer less rows.
