You already might have heard of the Raspberry Pi. It is a credit-card sized PC from the Raspberry Pi Foundation and is going into mass production and distribution these days. There is a huge demand for “the Pi” and the first orders are limited to one per person. A few weeks ago I got my Pi delivered and started working …Read More »
Welcome!This site is about various topics from the world of microelectronics, tinkering, software development, and other related topics. You can find our popular Raspberry Pi add-on boards ControlBlock and PowerBlock here as well as the GamepadBlock, our multi-platform USB interface for arcade and original game controllers.
This site is also the birth-place of RetroPie, the popular retro-gaming project for the Raspberry Pi. You can find articles about the original idea and articles of the first years of the project here.
Enjoy your stay on our sites!
In my last post, I described a minimum configuration for an ATMEGA microcontroller, which is also used in the earlier Arduino boards, and I also explained how to program that microcontroller with an ISP. Here, I present a small all-purpose board that contains exactly that minimum configuration together with an USB-B connector. The USB connector has two purposes: First, it …Read More »
After having finished my first projects with an Arduino I started to look for ways, which would allow me to port my project to an Arduino-compatible minimum configuration board. Ideally, I wanted it to be much cheaper than a new Arduino board. In this post, I describe how to put together a working protoype on a breadboard that can easily …Read More »
This is another short example of a demo application that makes use of the V-USB library together with an Arduino. I show, how an USB keyboard functionality can be implemented.Read More »
Two months ago, I discovered the all-purpose text editor “Sublime Text 2“. This editor became my favorite editor very quickly for several reasons.Read More »
After having finished a fully working prototype for a SNES-USB-iCade adapter in a Lego enclosure I decided to design an enclosure that would not be based on Lego bricks.Read More »
Previously, I presented my SNES-to-USB-Adapter. The adapter emulates a USB keyboard with which it is also possible to play iCade games on the iPad. Now, my ambition is to give it a more professional and solid look and one thing to do would be to put most of the wiring into a printed-circuit board (PCB).Read More »
Recently, I finished a little do-it-yourself project: Inspired by this biorhythm article, I decided to build my own iCade-gameplay adapter. During the planing stage, I soon realized that it would be nice, if I could also use the adapter with other available emulators out there, as well as for two-player games.Read More »
I wanted to have a little backup script running as a cronjob that efficiently generates a rotating backup for each day of the week.Read More »
I used this command to sync a folder structure with rsync in combination with a file filter:Read More »
