WinchBot 1.5 works better.
Blog November 27, 2017
With my Sponsor RS-Components I have build an improved version of my WinchBot that I call version number 1.5.
The final product - called version 2.0 - will be displayed on the SPS IPC Drives 2017 in Nürnberg, Germany at the stand of RS-Components.

The video about the base car for another rover is online.
Blog November 19, 2017
I got a 1:8 model car of a monster truck that will be converted to another rover (R8). In the first part I'm showing the base car and talk about some issues of the conversion.

Video and build instruction of R7 are online.
Blog November 08, 2017
The page with the build instruction of R7 including the video is online. I am still working on the software and I have also a couple of minor improvements of the hardware in mind, however even in the current stage the robot works fine.

R7 goes out for a test ride!
Blog November 5, 2017
The control page of R7 is online and today is another test run. The rover is outdoor for the first time even while it is raining today here in Germany. Meanwhile I have 3D printed a cover for my latest robot so that the water falling from sky should not bring the explorer into trouble.

R7 lives!
Blog 29. Oktober 2017
Today you can control my latest robot R7 on a special test page. It will become part of my RoboSpatium as soon as the battery sensor is implemented and the control interface got a redesign.

I visited RS Components
Blog October 5, 2017
I was at the headquater of the German section of RS Components in Mörfelden-Walldorf. During the hours of my visit I was pushed into a universe called "Social Media" and that is more or less an onknown space to me. The video report from beyond that new frontier will follow by RS components as soon as all the raw material is edited by their social media experts. I am curious about the result.

The reason for my trip is a project made with parts from my sponsor that I am currently working on. It will be displayed at the SPS IPC Drives 2017 in Nürnberg, Germany from November 28 to 30, 2017 at the stand of RS Components. I will be there and I am looking forward to talk with technicians and creators. Thursday is a special day for students.

Before driving home I could put a box of Raspberry Pis into the boot of my 2CV estate special edition and you know my slogan:
A Raspberry a day keeps boredom away!

Review of the Anet E10 3D printer
Blog October 2, 2017
The Anet E10 is another 3D printer I got for a review. The test wasn't free of trouble, but to my mind problems are no reason to start whining, they only need a soulution ...

Test drive R6
Blog September 23, 2017
The batteries of R6 are recharged and another public test will start at 10:00 CEST (UTC +2) lasting for the whole day. During this test run I will continue optimizing the picture stream. With that I'll try to reduce the traffic generated by the rover to get a continuous stream even in areas with low Internet bandwidth. Besides various resolutions, the color might also fade away whenever the rover transmits grey scale images, such as the early moon rovers did.

You can enter the control center of R6 to take part on the test runs. Have fun with driving my rover during the daylight hours and give a feedback whether all works fine with your equipment or what went wrong eventually.

A new rover
Blog September 14, 2017
I converted a commercial remote controlled car to a new rover for my Robospatium.

The first public test run will be next Sunday (September 17th) at 10:00Uhr Central European Summer Time (UTC+2).

Review of my first Delta printer.
Blog June 20, 2017
With the Anycubic Kossel the first 3D printer in Delta design has arrived in my workshop. Delta printers move the print head through 3 linear drives and push rods. The special kinematics makes the needed calibration tricky.

Winchbot 2 under construction.
Blog June 07, 2017
I am working on an improved version of my WinchBot. I am using bipolar stepper motors for driving the winches and a Raspberry Pi operates as computing unit. I have cut the acrylic plastics with CNC v3.2.1 which was the test run for the improved coolant flow of this machine - it works really fine.

Physical Computing reloaded
Blog 02. Mai 2017
With the microcontroller starter kit from my sponsor I have started a new series about "Physical Computing", something I had in mind for many months. I will add new chapters to that series every now and then, explaining in detail how to build, connect and program DIY peripherals using microcontrollers or single board computers.

You can get the starter kit on Gearbest.

My first commercially available CNC router.
Blog March 15, 2017
A new package from China arrived. The kit of a CNC engraver type T8 includes 3 bipolar stepper motors, an electronic board, aluminum profiles for the frame and more parts for a compact, functional machine. I got the engraver from the online store and a review video about the device will follow, soon. After that I will examine what else can be done with that interesting machine...

Coolant flow and CNC table got a redesign.
Blog March 13, 2017
Work on CNC v3.2.1 goes on. The filter system is now outside the bowl unter the CNC table.
I have added a (double) Acrylic plastics sheet on the CNC table, as well as guides on the edges. With that, workpieces can be fixed more easy.
The next test run will show if the (reduced) G code commands are interpreted exactly by the new software.

Special offers by one of my sponsors
Blog March 9, 2017
From I already received my first 3D printer. More parcels are on their way to Germany. On my new page with shopping tips you can find a list of products I already used in my projects and things to come...

Work on CNC v3.2 goes on.
Blog March 6, 2017
I am typing on the source code of CNC v3.2.1, to implement G code functionality. Furthermore I am redesigning the coolant flow to get the filter system out of the bowl underneath the table, so that I can remove chips while the machine is running. Third update in progress is the clamping mechanism for workpieces on the CNC table.
February 27, 2017
New videos are online
Blog February 27, 2017
I am short of time, which is why the sites about my 3D printer review and my WinchBot are still under constuction. The video about my WinchBot was scheduled for today, so here it is:
The link is still marked as private; you can watch it, but it's still not listed on YouTube. The note to all my followers will go out this week, as soon as the documetation is published.

Update March 2, 2017:
The page about WinchBot is online, the video is public now.

My 3D printer review is already public, same as the page about the printer, but there is still not much information listed:
3D Drucker Tronxy P802.

Update March 3, 2017:
The pictures from the assembly of the printer are online.

February 20, 2017
3D printing is here!
Blog February 20, 2017
Gearbest sent me a 3Dprinter kit type Acrylic 3DCSTAR P802-MHS.
Gearbest is an online electronics seller based in China, shipping to most countries in the world. The prices this company offers are definitely lowest. Including shipping to Germany, the printer is clearly less than 200,-€! Don't forget to add filament to your order, because for this price, all you get is the bare printer kit.
I will use the printer to write a short series of chapters (including videos) about filament printing, starting with the mechanics needed to do 3D printing.
First thing to be done is assembling the kit...
The video about my WinchBot is available for my Patreons and it will go public in a week - stay tuned!
February 13, 2017's a WinchBot.
Blog February 13, 2017
All parts of my latest project are assembled, the circuit is soldered and the software written.
Next thing to be done is recording video sequences and put it all together in a new chapter.
February 6, 2017
Work on my new robot goes on.
Blog February 6, 2017
The winches are in place. The central part with 5 servos is missing. As soon as it is in place, I will start coding.
You still can guess how it will work...
January 30, 2017
The starting page of my project got a redesign.
The "News" section is now part of the starting page. The intention is to give you information about what is going on at least on a weekly base. Many of my projects require a long preparation until a machine runs, a video is recorded and schematics or animations are painted. With the blog like starting page you will see that I am still working on this project ;-)

Blog January 30, 2017
The machine under construction is another robot. Guess what it will look like and how it works...
