Coming full circle LMAO

If we’re being honest with ourselves, we can admit that most of the cyberdeck projects out there lack a true purpose. People create them because they’re fun to build and cool to see in action, not necessarily to use for any specific application in the real world. But Paul Lagier’s new cyberdeck is an exception, because he designed it for 3D printing.

Whether you’re a seasoned electronics engineer or just starting out as a hobbyist, it’s a good idea to have a few all-in-one development boards on hand. When inspiration strikes, the last thing you want to do is spend weeks designing a circuit and waiting for the parts to be shipped to your door. You want to strike while the iron is hot and turn that great idea into a reality. By integrating many commonly used components into a single package, all-in-one boards make prototyping fast and easy.

Pseudonymous maker “PickentCode” has designed a compact, portable Raspberry Pi-powered cyberdeck designed for experimenting with electronics in the field — complete with integrated solderless breadboard: the CyberPlug.

Laser welding is getting a lot of hype right now as the tech starts to trickle down into the prosumer market. The primary advantages, compared to something like MIG welding, are precision and reduced heat. Those just happen to be attributes you’d want in a metal 3D printer, so Cranktown City strapped his Sky Fire WeldStar laser welding machine to a 3D printer motion system to see what would happen.

Norm Jackson and colleagues at Thort Werx are looking to put a low-cost mixed-signal oscilloscope and logic analyzer on every desk, turning to a pair of Raspberry Pi Pico 2 microcontroller boards to power the Picotronix — opening for crowdfunding soon.

It may not occupy much space in the minds of most people, but as an electronics hobbyist or professional engineer, you never know when you’re going to need to do a little hacking. Whether that involves checking out the security of a computer network or trying to fix a broken gadget, you’ll need the right tools to help you get the job done. Fortunately, there are better tools available today than ever before, like the Flipper Zero, for instance.

This project focuses on recreating the Tricorder as a functional hobby build, turning a famous TV prop into a real, working handheld device while staying true to its original purpose and visual style.

Ever wanted to build custom battery packs for electric bikes, solar power banks, or RC projects but found commercial spot welders too expensive? I’ve got the perfect solution! In this Instructable, I’ll show you how to build a powerful yet affordable battery spot welder from scratch. This isn’t just another simple project—it’s a professional-grade tool that uses the classic NE555 timer and parallel MOSFETs to deliver precise, controlled welding pulses.

Introduction

Sometimes just the thought of choosing components, designing a PCB, and assembling and testing the hardware is enough to kill a perfectly good idea for a new electronic gadget. That’s a lot of work, and when we are deciding what to do with our free time, work is not usually the number one choice. It is for this reason that hobbyists need to have tools available to them that will help them cut some corners to get a prototype up and running quickly.

A small Brazilian startup is looking to offer some competition to the popular Flipper Zero electronics multitool with the High Boy, a gadget that looks like a knockoff Apple iPod but offers a wealth of capabilities — and which, High Code says, will be released under an open source license.

With an ever-increasing availability of new technologies, we created an affordable bionic leg that is accessible to everyone. Find this and other hardware projects on Hackster.io.

There are a million ways to use a tiny single-board computer in a hobbyist project, but one of the most obvious might be to turn that little board into a full-fledged, pint-sized computer. Redditor stopdesign has done just that, and the result is a simple, yet beautiful handheld computer that I absolutely don’t need, yet cannot imagine living another day without. The goal of the project was to create a distraction-free coding computer that can be used anywhere and everywhere. But since it runs Linux, it could just as easily be repurposed for other tasks.

Hardware and embedded software engineer Kévin Courdesses has replicated research into breaking the flash encryption on selected Espressif ESP32 microcontrollers — including the ESP32-C3 and ESP32-C6 — using side-channel attacks to extract data and even bypass secure boot functionality.
