The first step towards designing and building a custom keyboard, from the very first principles, using an Arduino-type microcontroller.
Although building and deploying a simple program to an Arduino board is a point-and-click operation using the Arduino IDE, implementing more complex programs requires more robust build tools. This article describes how to build on Linux using command-line tools -- a process that is nowhere near as easy as it should...
This is a design for a robust, wooden enclosure for a Raspberry Pi, battery power supply, and touchscreen, that can be made using hand tools.
This article is part of a series on building a customer Linux installation for a Raspberry Pi-based appliance. It explains how to install and set up the minimum software to get audio playback working.
This article is part of a series on building a customer Linux installation for a Raspberry Pi-based appliance. It explains how to set up a system which hitherto only boots to a root shell, to a network-aware installation with service management.
This article is part of a series on building a customer Linux installation for a Raspberry Pi-based appliance. It explains how to obtain and install fundamental utilities for use in a system with a read-only filesystem, and no package manager.
It's entirely possible to run simple, X-based applications in an appliance-based Linux installation: you just have to dispense with the graphical desktop and all its baggage. This article explains how.
Switching loads of an amp or two with a Raspberry Pi or a microcontroller can be accomplished using a small number of inexpensive components. Suitable circuits are widely published, but the details of operation are not always described.
This article is about using an I2C analogue-to-digital device for applications like reading sensor values or monitoring backup batteries. With all the technical bits left in.
Writing graphical applications for minimal and embedded Linux systems can present a challenge. One of the problems is producing nicely-rendered text without the facilities that a graphical desktop would provide. This article describes how to use the FreeType library to render text to the Linux framebuffer.
