Kindleberry "Paperwhite" Pi

Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

  • Raspberry Pi
  • Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
    • You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
  • Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.

KUKA IO

This is a WIP documentation on the setup and usage of KUKA IO modules

IO Bus and Modules

Industrial IO Modules come in different filed buses depending on the KRC setup. DeviceNet, Profibus and EtherCat standards are available depending on the KRC. Most KRC use Beckhoff modules. Most common modules are digital IN, digital OUT, analog IN and analog OUT.

Brother P-Touch PT-P300BT bluetooth driver python

Controlling the Brother P-Touch Cube label maker from a computer

The Brother PTP300BT label maker is intended to be controlled using the official Brother P-Touch Design & Print iOS/Android app. The app has arbitrary limits on what you can print (1 text object and up to 3 preset icons), so I thought it would be a fun challenge to reverse engineer the protocol to print whatever I wanted.

Python code at the bottom if you want to skip the fine details.

Process

Intitially I had a quick peek at the Android APK to see if there was any useful information inside. The code that handles the communication with the printer in Print&Design turned out to be a native library, but the app clearly prepares a bitmap image and passes it to this native library for printing. Bitmaps are definitely something we can work with.

Anycubic i3 Mega configuration for Klipper (with TMC2209 + SPI, BMG extruder with stock motor, pressure advance and BLTouch clone)
# This file contains pin mappings for the Anycubic i3 Mega with
# Ultrabase from 2017. (This config may work on an Anycubic i3 Mega v1
# prior to the Ultrabase if you comment out the definition of the
# endstop_pin in the stepper_z1 section.) To use this config, the
# firmware should be compiled for the AVR atmega2560.
# See the example.cfg file for a description of available parameters.
