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.
