Hardware Hacking: BreadBin and Arduino

Hardware
  • BreadBin Is An 8-bit TTL CPU On A Breadboard, In A Bread Bin | Hackaday

    The total circuit is incredibly compact for a complete CPU, using just 33 chips. This includes 64 KB of flash to store programs as well as a 555 timer to generate a clock signal. I/Os are limited to simple eight-bit input and output buses, but a sixteen-bit address bus gives it plenty of space to add ROM, RAM or fancier interfaces.

  • Duco is a wall-climbing robot that paints circuit murals | Arduino Blog

    An Arduino Uno board controls Duco through a motor shield. It has two stepper motors, a servo motor, a linear actuator, and a UV light. It is capable of switching between two different pens — normally the conductive and dielectric ink. The UV light cures the ink after Duco applies it to a wall. Most of Duco’s frame parts were 3D-printed.

  • OMNi is a modular, omnidirectional robot for museum duties | Arduino Blog

    Museums allow people to explore topics in history, science, and much more through the use of exhibits that are often comprised of screens or some other interactive medium. Staff are given the role of visiting each one periodically and checking to see if they still work correctly as well as guide visitors around the area, thus taking them away from other tasks. To solve this problem, a pair from EDM Studio in Vancouver (Will Donaldson and Darran Edmundson) wanted to build an autonomous telepresence robotic platform, called “OMNi,” which could do both on its own.

  • Portenta H7 Lite Connected brings back WiFi & Bluetooth - CNX Software

    Arduino has launched another Arduino Pro board! Well, sort of. Let’s not get too excited. The Portenta H7 Lite Connected is based on last month’s Portenta H7 Lite that itself was a cost-optimized version of Portenta H7 board without a wireless module, USB-C video output, and only fitted with the lower cost Microchip ATECC608 secure element.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
