Video on LED matrix
In cooperation with NextPCB, a manufacturer of printed circuit boards, I created a video on how an LED matrix works. This continues my series on "Physical Computing". A second video, that will present the circuit boards, that origin from my cooperation with NextPCB in detail, will follow, soon.

Kywoo Tycoon Kickstarter
I got a pre-production unit of the Kywoo Tycoon 3D printer, for which a Kickstarter campaign is currently running. Here is my review including a video.

In the hope that real Makerfairs will take place again in 2021, I am currently clearing my London taxi for the German MOT. A brief look at the construction site can be found in the chapter about my London Taxi International TX2.

Direct granules printer version 2
Short before this year's Hackaday Prize was ending, I got a new version of my direct granules 3D printer up and running. You can see the current stage of development including a video in the new chapter about extruder V2.
My new series about "Machine elements" starts with the chapter about adjustable joints.

Remote controlled Raspberry HQ camera
I have purchased two of the brand new Raspberry Pi HQ camera modules including lenses to give you a hand on these gadgets via remote control in my RoboSpatium. In the chapter with the build instruction you can watch my video about that project.
Virtually Maker Faire
On May 23, 2020 the Virtually Maker Faire 2020 takes place and I am participating with my RoboSpatium. Details including a short promotion video are available on my page about the World Tour Rover.

My latest Rover is also the largest one I have built to date. It is based on a Hover or balance board. You can watch the video on the page with the build instruction.

Amplifying digital signals with ICs
How to amplify digital signals and so how to switch loads with GPIOs using Integrated Circuit chips including example circuits is shown in my latest chapter about "Physical Computing".
Happy Easter holidays!
You can hunt for Easter eggs in my RoboSpatium for the first time. The event takes place on April 12 + 13, 2020 for a couple of hours each day. If you'd like to participate in the exploration, you must enter my RoboSpatium and drive Rover number 17.

Switching loads through N-channel MOSFET
I have added a chapter about switching loads with a N-channel MOSFET to my "Physical Computing" series. With that, you can learn how to shift the limits of GPIOs in order to control high loads with your Raspberry Pi or Arduino.

Parts for Rover R15 arrived
The parts for my next Rover project have arrived. It is a project with multiple sponsors being involved:
The vehicle will be based on a so called "hover or balance board" that I got from Gearbest.com.
The electronic components needed to turn the board into a remote controlled vehicle are from RS-Components.
I got the filements needed to print the mechanics from Clemens Mayer (mayermakes.at), with the words "make something". That something will become my largest Rover so far, suitable for outdoor missions so that the sphere of influence of my RoboSpatiums will grow.
I got a pi-top
The developers of the pi-top company asked if i'd like to start a project with their latest product, the pi-top. My idea to create another Rover for my RoboSpatium was accepted and so the package entered my workshop a couple of days later. The Rover isn't finished yet, but I'd like to give you a first look on the pi-top.

My first resin printer has arrived in my workshop
With the Longer Orange 10 I got my first DLP printer. This printing technique hardens resin selectively through UV light. Details about the working principle are available on my Orange 10 review page.
