PowerBlock: A(nother) Power Switch for the Raspberry Pi

The PowerBlock is an add-on board for the Raspberry Pi (version 1, 2, and 3) models A+ and B+. It provides a microcontroller-based power-switch functionality. This article describes the PowerBlock itself, as well as how to connect a power switch and how to install the driver. Functionalities The PowerBlock provides a power switch functionality. Why might this be of interest …

ControlBlock: Power Switch, Game Controllers, and I/O for the Raspberry Pi

The RetroPie Project has motivated many people to build their own gaming stations. Two issues regularly came up in discussions about these projects: First: What is a simple solution for turning the Raspberry Pi on and off with a power switch in a smarter way than cutting the power supply and risk data loss? Second: What is a simple way for …

Review: T962A Reflow Oven Controller Upgrade Package

while ago I posted a review about the reflow-flow oven T-962A. As written in that post the T-962A has certain flaws: The heat is generated by IR heaters that do not distribute the heat evenly within the oven. This made the results of the soldering processes unreliable. Also, the responsiveness of the user-interface is not that good: Tuning the reflow profile …

The RetroPie GPIO Adapter

If you want to use your Raspberry Pi for gaming you certainly want to attach some sort of controller(s) to it. Since the Raspberry comes with two USB ports one way would be to simply attach any sort of USB gamepad or joystick via these ports to it. Besides the configuration this approach has the disadvantages that one or both …

Connecting SNES sockets to the Raspberry Pi: An assembly guide

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 an SNES-controller interface for the Raspberry Pi. A core element of this interface is a SNES-adapter PCB that I recently designed and that does nothing more than providing all needed connections between the GPIO pins …

Pancake Board: Arduino-Compatible Minimum Configuration Board for ATMEGA168/328 with USB Connector

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 …

From Arduino to Breadboard with a Minimum Configuration

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 …

PCB for SNES-iCade-Adapter

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).
