The use of integrating factors is a well-known method for turning an intractable differential equation into an integration problem (which may itself turn out to be intractable, but we live in hope). The method is usually described in...
This article describes how to do simple temperature measurement with a Raspberry Pi, and I2C analog-to-digital converter, and a thermistor.
A small step in the right direction, or political correctness gone mad?
The ease of installation and use of modern desktop Linux distributions comes at a price. I review a couple of low-complexity alternatives to mainstream Linux distributions: Alpine and Devuan.
Why was the non-existent planet Vulcan so frequently sighted by astronomers in the nineteenth century, and what can contemporary scientists and science students learn from this episode?
There are many kits and plans available for constructing miniature mechanical keyboards. But what do you do if you want a layout the nobody else seems to use? Build it from scratch.
Although connecting a USB keyboard to an Arduino-type microcontroller without addition hardware can be tricky, there are no such problems with many 90s keyboards. This article is about giving new life to old keyboards, by using them as...
Why do so many IT professionals like to tinker with vintage computers and software?
Peli cases have a reputation of robustness, and look like a promising way to implement a rugged terminal using a Raspberry Pi.
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...
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...
