We see a fair few glitcher projects, especially the simpler voltage glitchers. Still, quite often due to their relative simplicity, they’re little more than a microcontroller board and a few components hanging off some wires. PicoGlitcher by Hackaday.IO user [Matthias Kesenheimer] is a simple voltage glitcher which aims to make the hardware setup a little […]
Touchpads, or trackpads, have been around since the 1980s. Today, you can often find them in laptops and notebook computers as pointing devices. With no moving parts, a trackpad are easy to integrate into the body of a portable computer. they’re much smaller than the traditional mouse. Until the advent of multitouch and gestures over […]
The Raspberry Pi has been around for over a decade now in various forms, and we’ve become plenty familiar with the Pi Pico in the last three years as well. Still, these devices have a great deal of potential if you know where to look. If you wade beyond the official datasheets, you might even […]
When we think of programmable hardware, we think of FPGAs. But they’re not the only option. [Oliver Schmidt] has been exploring how the Raspberry Pi Pico can serve in such a role for the classic Apple II. The talk was presented at the KansasFest event this year, and it’s well worth diving into! [Oliver] has […]
How hard is it to make a fully standalone SDR? [101 Things] shows you how to take a breadboard, a PI Pico, and two unremarkable chips to create a capable radio. You can see the whole thing in the video below. The design uses a standard Tayloe demodulator. There’s also an encoder and an OLED […]
From the “why didn’t we think of that” department comes [dupontgu’s] pong mouse project. The mouse appears and acts like a normal computer mouse until you click the scroll wheel. When you do, the mouse rapidly moves the cursor on the connected computer to play pong. Obviously, though, the paddles and the ball all look […]
Raspberry Pi’s first foray into the world of microcontrollers, the RP2040, was a very interesting chip. Its standout features were the programmable input/output units (PIOs) which enabled all sorts of custom real-time shenanigans. And that’s not to discount the impact of the Pi Pico, the $4 dev kit built around it. Today, they’re announcing a […]
