For frantic hacking sessions where seconds count, this forearm mounted oscilloscope with fingertip probes built by [aniketdhole] might be just what you need. Well, maybe. It’s not immediately clear why you might want to wear an oscilloscope on your arm, and sticking your fingers inside of powered up electronic devices sounds specifically like something your mother probably told you not to do, but here it is anyway.
There’s a truckload of news from the Arduino Tooling Team today: Arduino CLI 0.19.0 is now available! This release has tons of great enhancements, exciting new features and heaps of bug fixes. Some things required quite a bit of breaking changes but they’re worth the hassle.
The highlights of this release are certainly the addition of pluggable discovery and the internal restructuring of the startup steps of the Arduino CLI. These affected the JSON output of some commands and the gRPC interface functions, which is documented in the upgrading guide.
I love the retro vibes that the Raspberry Pi 400 gives off. The all-in-one computer-in-a-keyboard design makes me feel like I’m working with a computer from my childhood. The only problem I have is that when I look up from the keyboard, it’s just another modern(-ish) computer running Linux. I set out to fix that with the Pi64.
Inspired by the Commodore 64, the Pi64 boots into a C64-themed bash shell in text mode. No X Server is involved. It is not a C64 emulator, it is Raspberry Pi OS, so you can get real work done; it just extends the Pi 400’s retro feel to the screen.
The best streamers keep their audience constantly engaged. They might be making quips and doing the funny voices that everyone expects them to do, but they’re also busy reading chat messages aloud and responding, managing different scenes and transitions, and so on. Many streamers use a type of macro keyboard called a stream deck to greatly improve the experience of juggling all those broadcasting balls.
Sure, there are dedicated commercial versions, but they’re kind of expensive. And what’s the fun in that, anyway? A stream deck is a great candidate for DIY because you can highly personalize the one you make yourself. Give it clicky switches, if that’s what your ears and fingers want. Or don’t. It’s your macro keyboard, after all.
In this episode I will ditch the idea of an ultrasonic mist maker and instead focus on more common fog/smoke machines. I will show you how they use “fog juice” in order to create smoke and at the end I will come up with my own crude mini fog/smoke machine design that did actually work. Let’s get started!
Xbox isn’t the only one rolling out Halo-themed hardware and accessories ahead of the release of Halo Infinite. The talented creator POPeART (formerly known as Xbox Pope) is at it again – this time with the “Needler Elite V2”.
It’s the same pattern we saw early on in August but instead of the standard Xbox Series X|S controller, it’s the series 2 version of the Elite controller – featuring the grips, fancier controller pad, coloured paddles and all the other extras.
Powered by a Raspberry Pi-based “PiPU,” this souped-up cartridge brings Google Maps to the NES — nearly a decade after Google’s gag.
Pseudonymous maker “ciciplusplus” has ported Google’s popular Maps application to an unusual target device: the Nintendo Entertainment System (NES) eight-bit games console.
This is what happens when cutting edge desktop hardware meets portability!
The PySpectrometer allows users to measure homemade dye lasers’ wavelength and perform spectroscopy on the cheap.
Les Wright developed PySpectrometer, a Python (OpenCV and Tkinter) implementation of an optical spectrometer. The device enables users to measure the wavelength of homemade dye lasers and perform spectroscopy at an affordable cost.
Back in 2019 we first came across the mutantC, an open source 3D printable Raspberry Pi handheld created by [rahmanshaber] that took more than a little inspiration from Sony’s VAIO ultra-mobile PCs (UMPCs) from the early 2000s. It was an impressive first effort, but it clearly had a long way to go before it could really be a practical mobile device.
Well after two years of development and three iterative versions of this Linux powered QWERTY slider, [rahmanshaber] is ready to show off the new and improved mutantC_v4. Outwardly it looks quite similar to the original version, with the notable addition of a tiny thumbstick and a pair of programmable buttons on the right side that can be used for input in addition to the touch screen. But inside it’s a whole other story, with so many changes and improvements that we hardly even know where to start.
