This tape cassette is actually a full-fledged computer (powered by a Raspberry Pi Zero W)

Raspberry PI News / By

The Sinclair ZX Spectrum was a compact and affordable personal computer when it first launched in 1982 for £125 (the equivalent of £470 or $745 in 2022). Designed to use tape cassettes for storage, it was also relatively easy to obtain media. But computers have gotten a lot smaller and cheaper over the past four decades, and …

A POWER BUTTON FOR RASPBERRY PI, COURTESY OF DEVICE TREE OVERLAYS

Raspberry PI News / By

As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a Raspberry Pi system. Using these DTOs it’s trivial to set up features like as a soft power-off button, triggering an external power supply and enable …
