I present: The PetRockBlock Pie. It is not yet another a Raspberry Pi case that has been specifically designed with a list of desired properties in mind. While the nice and compact design will let the case fit even into your living room as an eye-catcher, another advantage of the case is used, when you want to connect external components …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!
I just committed a major update for the RetroPie setup script available at Github. The corresponding blog post was also refined. A main element of the update is the possibility to install per-compiled libraries, which dramatically speeds up the whole installation of RetroArch, various cores, SNESDev, and Emulation Station. More information can be found in the post about the RetroPie …Read More »
If you want to install and setup RetroArch on the Raspberry Pi (TM) together with various emulator cores, all needed libraries for the SNESDev controller interface, and a graphical front end you can now go to https://github.com/retropie/RetroPie-Setup. There you will find an easy-to-use script that installs all essential packages for retro gaming on the Raspberry. I call it RetroPie script.Read More »
UPDATE: For connecting original controllers from game consoles or arcade machines, there is now the ControlBlock. It supported various controller types and provides even a power switch functionality. The ControlBlock is has its own page here. In a previous post, I described my idea of a universal console with the Raspberry Pi. I presented, what I called, the SNESDev-RPi, which is …Read More »
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 »
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 »
