NOUS: uNdersea visiOn sUrveillance System

Reading Time: 3 minutes Dr George Papalambrou and his colleagues Vasilis Mentogiannis and Kostas Katsioulis, from the NTAU’s School of Naval Architecture and Marine Engineering, knew plenty about Raspberry Pi before selecting it for their underwater archaeology surveillance project. “It was our first choice from day one,” George says. For a start, he had used Raspberry Pi alongside Apple HomeKit…… Continue reading NOUS: uNdersea visiOn sUrveillance System

PecanPi Streamer review: high-end audio driven by Raspberry Pi 3B

Reading Time: < 1 minutes Minimalist This case is minimalism taken to a new level. Looking at the rear, we see the ports from a Raspberry Pi 3B, and not only the usual phono (RCA) sockets but XLR sockets too. This unassuming box is aimed right at the professional market as well as the audiophile. Driving the PecanPi is Volumio,…… Continue reading PecanPi Streamer review: high-end audio driven by Raspberry Pi 3B

Entry/Exit Notifier: A simple, well-engineered build

Reading Time: 3 minutes Sounds simple, right? Wayne had found himself forgetting to send the necessary emails, and thought the process was a bit tedious when he did remember, which became the impetus for the project. There’s a little bit more to it than just being a button that makes it pretty cool though. “I used an old 512MB…… Continue reading Entry/Exit Notifier: A simple, well-engineered build

CutiePi review: a Raspberry Pi 4 tablet

Reading Time: 3 minutes While one of its headline features is that it’s very thin (14mm thin to be exact, thinner than a Raspberry Pi 4), it doesn’t skimp on screen size with an 8-inch IPS LCD touchscreen running at 1280×800. It’s bright and very responsive, the latter thanks to a Compute Module 4 being built into the tablet…… Continue reading CutiePi review: a Raspberry Pi 4 tablet

Time Machine Radio

Reading Time: 3 minutes “I had thought a little music box which played content from the 1930s and 1940s would be an excellent addition to the car when it’s on display,” explains George. “After putting some thought into making one myself, the idea of having content from each decade in the 20th century somehow seemed more naturally appropriate.” Radio…… Continue reading Time Machine Radio

M4All microscope

Reading Time: 3 minutes The team, the NanoBioPhotonics group at the University of Strathclyde, have been using their imaging expertise to “investigate the mechanisms that macrophages (a type of immune cell in the body) employ to remove respiratory pathogens”, pathogens that, among other things, can lead to pneumonia or meningitis. “From my experience using research microscope facilities to image…… Continue reading M4All microscope

Raspberry Pi hardware hacks

Reading Time: 3 minutes Portable power One of the easiest ways to take Raspberry Pi portable is to use a mobile phone charging bank. These sticks typically use a USB connection to hold power, and you can plug them into Raspberry Pi just like your phone charger. It’s a hack though – if you want a more secure solution,…… Continue reading Raspberry Pi hardware hacks

REVIEW: Tiny 2040

Reading Time: 2 minutes You can flash it with the Pico firmware and program it with MicroPython, C/C++, or CircuitPython. So it’s very versatile and easy to get started with. To achieve a smaller footprint, a few compromises have been made. Most notably, the Tiny 2040 only has a total of 16 pins versus Pico’s 40, plus a debug…… Continue reading REVIEW: Tiny 2040

Penkesu Computer

Reading Time: 3 minutes Penk was looking to build upon his work with mechanical keyboards. “I’d learned not only how to build them from scratch, or mould and cast my own key caps, but also how to use a laser engraver to melt pigment onto key caps to print my own legends,” he says. “I recall staring at those…… Continue reading Penkesu Computer

OPINION: Rubber Soul

Reading Time: 2 minutes This makes sense. Raspberry Pi is ideal for rediscovering retro classics; its modern processor is capable of faithfully emulating just about every beloved computer of our generation. And like many computer geeks of our generation, we loved many different 8- and 16-bit computers. My beloved computer of this month is the ZX Spectrum. Which is…… Continue reading OPINION: Rubber Soul
