  • Tiny Raspberry Pi Zero 2 W Robot Made For Robot Sumo | Tom's Hardware

    The Raspberry Pi in robotics is a smart mix—but what happens if the kit you ordered doesn’t support the Pi? You get creative like maker and developer WallComputer, of course! In this Raspberry Pi Zumo project, they've converted the classic Pololu Arduino Zumo kit to support the latest Raspberry Pi Zero 2 W.

    This tiny robot uses tank-like treads to get around, which provide the traction needed for Sumo robots designed to push each other around. Traditionally this type of robot is controlled by an Arduino Uno, but this version uses both a Raspberry Pi Zero 2 W and an STM32 microcontroller with a little help from a couple of custom PCBs. To see how much has been modified, take a look at the original product listing for the Zumo kit over at Pololu’s website. This modification was not only necessary to use the Pi, but also to add additional features like a rechargeable battery pack.

  • Best Raspberry Pi Deals 2022 | Tom's Hardware

    With more than 40 million units sold and a powerful community of makers and fans behind it, Raspberry Pi is more than a single-board computer; it's a huge platform with an even bigger ecosystem behind it. Whether you want to build your own robot, create an A.I.-powered security camera, or just set up a simple computer for programming and web surfing, the Pi is for you.

  • Raspberry Pi Pico Drives $10 Nintendo 64 Flash Cart | Tom's Hardware

    We love retro gaming on the Raspberry Pi but there’s nothing quite like retro gaming with a Raspberry Pi. Instead of running an emulator on a Pi, this Raspberry Pi Pico Nintendo 64 cart project, created by maker and developer Konrad Beckmann, is using the Raspberry Pi Pico to host a ROM that runs on the original Nintendo 64 console.

    I built a working Nintendo 64 flash cart with a Raspberry Pi Pico, a breakout board and some extra flash for less than $10.It boots Super Mario 64. Can't wait to optimize, improve and add more features to it!Lots of stuff left before it's ready for general users though. pic.twitter.com/C1qVaTTfHiJune 22, 2022

  • Raspberry Pi Pico Detects Gamma Rays in Open Spectroscopy Project | Tom's Hardware

    There are many useful things you can do with a Raspberry Pi Pico (opens in new tab), as our listing of the best Raspberry Pi Projects (opens in new tab) underlines. However, here’s one we admit we’d never thought of: detecting radiation. Physicist Matthias Rosezky, AKA Nuclear Phoenix (opens in new tab), whose work has also been covered by Hackaday (opens in new tab), has written up a detailed account of building a DIY gamma-ray spectrometer in IEEE Spectrum (opens in new tab).

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

  • Things You Can And Can’t Do

    And it got me thinking about what you can and can’t do — what you do and don’t have control over.

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

  • How to Install CUPS Print Server on Ubuntu 22.04

    If your business has multiple personal computers in the network which need to print, then we need a device called a print server. Print server act intermediate between PC and printers which accept print jobs from PC and send them to respective printers. CUPS is the primary mechanism in the Unix-like operating system for printing and print services. It can allow a computer to act as a Print server. In this tutorial, we learn how to set up CUPS print server on Ubuntu 22.04.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.

  • Raspberry Pi Pico Used in Plug and Play System Monitor | Tom's Hardware

    Dmytro Panin is at it again, creating a teeny system monitor for his MacBook from scratch with help from our favorite microcontroller, the Raspberry Pi Pico. This plug-and-play system monitor (opens in new tab) lets him keep a close eye on resource usage without having to close any windows or launch any third-party programs. The device is Pico-powered and plugs right into the MacBook to function. It has a display screen that showcases a custom GUI featuring four bar graphs that update in real-time to show the performance of different components, including the CPU, GPU, memory, and SSD usage. It makes it possible to see how hard your PC is running at a glance.
