Matchbox computers: Small is beautiful (and powerful)

Filed under
Hardware
Gadgets

You could sum up most of the history of computing in one word: smaller. Each successive generation of computing devices has been tinier, more energy-efficient and more powerful than the previous one. Now we've reached a point where an entire PC can be crammed into a space not much larger than a matchbox or a stick of gum.

This new wave of "matchbox computers" (also known as "thumb PCs") has ushered in not just new form factors but new kinds of applications. Hobbyists have flocked to these tiny systems, attracted by their size, low cost and inherent hackability.

Raspberry Pi was one of the first open-source matchbox computers: inexpensive, tiny and energy-efficient.

  • Device Tailored Compositors with Qt Wayland at CLAAS E-Systems
    Have you heard about software in cars that run on embedded devices? Do you think that creating such software might be challenging? Well, welcome to a complete new world of complexity, welcome to the world of agriculture machines! For many years, automatic steering (on fields), terminals to control the complex mechanical operations of a self-driving 16 ton combine harvester on a soft ground, and self-optimization systems to optimize any tiny bit of your harvester, are key demands from customers. I, myself, am working at CLAAS E-Systems, the electronics and software department within the CLAAS group. Our group is well known for being among the leading manufacturers for combine harvesters, tractors and forage harvesters.
  • Qt Wayland Is Next Appearing On Tractors & Farm Equipment
    With Qt 5.8's Qt Wayland Compositor Framework taking shape, more developers are beginning to tailor a Qt Wayland compositor to their use-cases. One of those is a company specializing in farm equipment like combine harvesters, tractors, and harvesters. As a guest post on the official Qt blog, developer Andreas Cord-Landwehr of CLAAS E-Systems talked up Qt Wayland for their purposes in the highly-regulated agriculture industry.
