3D printing sugar
In the household a very common raw material, in 3D printing, however (at least so far), sugar is almost unused. This material can be processed with my direct granules extruder. Video number 5 on the extruder shows what to keep in mind when printing with this exotic material.

Hackaday Prize 2021
I entered the finals of the Hackaday Prize 2021 with my direct granules extruder! A video of up to 5 minutes must be created for the jury to present the project. This is video number 4 about the extruder.

Aufero Laser 1
With the Aufero Laser 1 from Ortur, another laser cutter or engraver has entered my workshop.
Direct Granule Extruder V3
The deadline for an application for a fellowship of the Shuttleworth Foundation "forced" me to publish the status of my research on my direct granulate extruder earlier than planned. In addition to a video that shows the extruder in action and in which I briefly address the extraction of raw material from failed prints, there is also a first, short build instruction for version 3.

LK5 Pro: Warping
I received an offer from Longer for a 3D printer that I was supposed to present in a video. Since I now find review videos totally boring and also had two unused ABS spools lying around in my tinkering basement, I instead examined how "warping" can be minimized by software.

Robotic arm composed of roof battens
As a weekend project I have created Robotic arm V1.0 using roof battens and other things I found in my workshop. Writing the documentation and recording a video took much longer. Looks cheap and that's what it is. However, it works much better than is looks!

Python for a laser engraver
With the Ortur Laser Master 2 Pro I got a laser engraver, with the help of which I will add chapters on machine control to my series on "Physical Computing".
Suitcase Rover R19
My latest laptop has 4 wheels and is based on a Raspberry Pi 4. The build instruction of R19 is online, including a video showing the vehicle in action.

With the first two "prototypes" of text terminals, which I am presenting in a new chapter on "Physical Computing", I will show in future chapters, how to transmit text messages, securely.

Python script as background service
How to pass parameters to a Python script running in background, is demonstrated in a new chapter on "Physical Computing".

Pulswe-width modulation in Python
I describe, how pulse width signals are programmed in Python. A special pulse width signal is required to control servos, which is also shown in the new chapter.
Python: Switching GPIOs
So far I have not eplained anything in depth about the software side of "Physical Computing". That will change now. The first chapter deals with switching GPIOs using "Python".

My latest rover, called "R18", is also my cheapest robot to date, which is why I made three of them. The software required to control it via a browser is also quite compact, but I put lots of effort into the build instructions, including a video.
You can see which of the three new servants is currently online and therefore free for a test drive in my RoboSpatium.
Have fun with exploring my robot room!

My review of the Mingda D2 is also a look back on 4 years of 3D printing.
To the right on the title photo you can see a new vehicle for my RoboSpatium. While recording the video of the Mingda, I have printed the parts needed to build a new type of Rover that will be coming next.
The "WorldPrinter", a machine I have created for an art installation of Theo Deutinger, arrived in Graz, Austria. All details about the project are available in the new chapter.
In the shipping box of the WorldPrinter, one of my Rovers traveled to Graz, too. More about that in my RoboSpatium.

Isolation milling with the CNC 3018Pro
With the help of a CNC 3018Pro from Mostics I have dived into isolation milling and so made a PCB. The full report including a video is available in the new chapter.
