Arduino
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 input devices for microcontroller projects.

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.

Back in the 70s, desktop computers booted to BASIC. In this article, I describe my efforts to implement a BASIC programming environment on the SparkFun Pro Micro, a small Arduino-like 8-bit 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 be. If we can build using command-line tools, we can manage a project using Makefiles and similar techniques.

Make an auxiliary LCD display for a computer that displays data sent to it over a USB connection. Ready-made devices of this sort are widely available, but it's more fun to build your own.
