When it comes to software on Raspberry Pi devices, one size doesn't always fit all. Raspberry Pi OS is ideal for many applications, but we recognise that it doesn't suit every use case or deployment model, particularly in a product that has a specific purpose. If you are building an embedded system or an industrial controller, you'll need complete control over the software resident on the device, and home users may wish to build their own OS and have it preconfigured exactly the way they want. For developers and organisations that require a custom software image, a flexible and transparent build system is essential; to support these customers, we have created rpi-image-gen, a powerful new tool designed to put you in complete control of your Raspberry Pi images.

This author has recently acquired a Polaroid camera. They're great fun, they work like magic, and they give you an excuse to stare intently at a blank space until meaning appears (one of our favourite hobbies). The other wonderful thing about Polaroids is that, bereft of the megasensitive optical sensors that modern camera phones have, they are really limited in how much light they let in, giving all of our photos a murky, 1970s brown feeling. Printables user Spacerower has brought some of that instant photo magic to this build, an instant camera that produces low-resolution black and white images using a thermal printer. It's powered by a 1200 mah lithium-ion battery, and uses a Raspberry Pi Zero W and a Raspberry Pi Camera Module. Other than the fact that…

We can end this exploration of programming with a look at the Rust programming language. Rust is probably not the first programming language you should learn. Maybe it shouldn't be your second either. But at some point, you are going to wonder if there is more to programming and how you can make your programs properly reliable, self-contained, and easy to manage. These are issues you can't really consider when your main problem is getting your code to work, but once you start making useful solutions, they are things you need to look out for. Rust was created with all these issues in mind. Python wants to be easy to learn and use; JavaScript wants every program to do something. Rust wants every program to be solid, safe, predictable, and…

Raspberry Pi | £24 / $26 | raspberrypi.com Verdict Superb sound quality when you hook it up to a hi-fi. This is one of four official Raspberry Pi digital audio boards – the others are the DAC+, DigiAmp (with integrated amplifier), and smaller Codec Zero. It boasts the highest audio quality of the range thanks to its Texas Instruments PCM5242 chip, which outputs high-definition 24-bit audio at 192kHz. That's far better than standard 16-bit CD quality, although you'll need to be an audiophile to notice the difference. What you will appreciate is the crystal-clear sound with a rich, warm feel. Just mount the board onto the 40-pin GPIO header of any Raspberry Pi computer and it's ready to use – no drivers required, nor external power. You can then use…

52Pi | £29 / $30 | 52pi.com If you really like your HATs to be multifunctional, this one may well be of interest. Designed for use with Raspberry Pi 5, it combines a DAC with an NVMe interface to add SSD (solid-state drive) for storage. Thinking about it, that makes a lot of sense for a NAS or home theatre setup, for which you want extra storage and high-quality sound. The DAC part is supplied by a HiFiBerry DAC+ Standard, delivering high-quality 24-bit/192kHz line-level audio via two RCA (phono) ports that you can connect to a hi-fi amp and speakers – there's no headphone jack. The board utilises the I2S protocol to connect directly to Raspberry Pi 5's CPU, preserving audio signal integrity. For the NVMe functionality, there's a standard…

The concept is fairly simple – download the software (rpimag.co/kiwisoftware), do a quick install, and then plug your Raspberry Pi into the device using an HDMI cable and an (included) USB-A to USB-C cable to connect keyboard and mouse. We've used several screen capture tools in the past for various reasons – whether it's live streaming, video making,…

Recalbox RGB DUAL 2 Recalbox is an add-on we've covered before – it allows you to hook a Raspberry Pi up to a CRT TV so that you can emulate classic console games the way they were meant to be seen – with beautiful scanlines. This new version is specific to Raspberry Pi 5, allowing even more retro and classic games to be played on an old telly kck.st/4iNbP96 AudioPlug This cool little audio dongle for Raspberry Pi includes a huge number of audio features beyond adding a 3.5mm jack back to the board – it also has an onboard microphone, Bluetooth audio functions, a JST stereo speaker connection, and more. kck.st/4iO3L86…

Raspberry Pi introduced its high-quality Raspberry Pi 45W USB-C Power Supply on 7 April, 2025. It is available now for the low price of $15. “Whether you're running a Raspberry Pi or charging a laptop, the quality of your power supply makes all the difference,” says Eben Upton, Raspberry Pi co-founder and CEO. Efficient regulation All Raspberry Pi computers need storage and power. While many users repurpose old power supplies and microSD cards, it's beneficial to have high-quality options. “Buying the cheapest SD card or USB wall wart you can find on Amazon is a guaranteed way to have a bad experience,” says Eben. “So over time, we started to regulate the accessories offered by our Approved Resellers. We would test resellers’ SD cards, to ensure that they had sufficient…

HiFiBerry | £60 / $65 | hifiberry.com Verdict Ideal for multi-speaker home theatre setups. HiFiBerry is one of the bestknown makers of audio boards for Raspberry Pi. The range includes the DAC 2, delivering 24-bit 192kHz sound and minimal noise and distortion due to a custom current-tovoltage output stage featuring highend filtering. The DAC8x is a unique beast, however, While most Raspberry Pi DAC HATs feature a standard two-channel stereo output, this one boasts eight channels, making it ideal for multi-speaker audio and home theatre setups. The possibilities are exciting – you could even use it for a DIY synthesizer project using something like SuperCollider. Those eight channels are output via four stereo 3.5 mm jacks. They are fed by four dedicated 192kHz/24-bit high-quality TI Burr-Brown DACs with a typical…

Pimoroni | £15 / $16 | pimoroni.com The Raspberry Pi Pico range of microcontroller boards is ideal for smaller electronics projects which don't require the full processing power of a Raspberry Pi single-board computer. If you need to output any audio, however, there's no obvious way to do it from a Pico, which lacks an audio output. You could always fiddle around with pulse-width modulation (PWM) to output audio signals from the GPIO pins by switching them on and off very quickly, possibly making use of Pico's Programmable IO blocks. That's fine for basic audio effects, but don't expect stellar sound quality. Alternatively, just grab a Pico Audio Pack. It adds a PCM5100A DAC to output high-quality (up to 32-bit, 384kHz) stereo audio through a 3.5 mm line-out connector –…

An email from a Japanese Raspberry Pi user caught our attention. D.M Entry Point has been creating cluster computers using old Raspberry Pi computers, including this one built with 16 Raspberry Pi 1 boards. They're planning to build one using every numbered model of Raspberry Pi through to 5, with a Raspberry Pi 2 version already completed. We're really interested to see the performance jump between models, although we'd hazard a guess that the jump from the single-core BCM2835 on Raspberry Pi 1 and the quad-core BCM2836 on Raspberry Pi 2 might be the highest. We are now talking to D.M. about a showcase of his project to explain how it works in a future issue.…

Raspberry Pi has announced a brand new product, the PoE+ Injector (Power-over-Ethernet). This enables users an affordable and easy way to add power to a compatible networked Raspberry Pi device for just $25. Announced by Eben Upton on 24 March, the new device simplifies deploying Raspberry Pi computers in locations that lack convenient power outlets. “Many of our favourite Raspberry Pi applications, from garden webcams to industrial controllers, involve putting our products in out-of-the-way locations,” explains Eben, “where they act as a bridge between the network and the physical world. But the more out-of-the-way the location, the more challenging it is to get power.” The brand new injector, developed with Microchip (microchip.com), supports the IEEE 802.3af (PoE, 13W) and IEEE 802.11at (PoE+, 25W) standards, along with mains voltages between 100V…

Split flap displays: they're a brilliant bit of retro technology, existing long before LEDs, OLEDs, 7-segment displays, and other modes of showing information. And yet none of those has the same majestic clickclack sound that a split flap display does. Maker Morgan Manley always wanted one of these for his desk, but most split-flap displays are large, loud, and have a load of wires hanging out the back – Morgan wanted something neater. And so he created this: a compact, modular and fully enclosed display. Each module is approximately 40 mm wide and 80mm tall, so the full eight-module device is only 320 mm long in total. The modules fit together with only a four-pin connector between each module, and it's powered via a USB-C power adapter. The build is…

rpimag.co/PCBHolder We love a functional print here at Raspberry Pi Mansions. Especially when we have a room full of printers, but inexplicably, not enough clamps to hold the things that we want to solder. One print that has come in handy recently is this perfect little PCB holder (designed by Shawn Quinn), which is the perfect size to hold a Raspberry Pi Pico in place. We printed this clamp in PLA using the Bambu Lab A1 equipped with the AMS (Automatic Material System). Although the AMS supports multicolour printing, each colour was printed separately in this case to minimise material waste from purge towers and excess nozzle ‘pooping’ – otherwise we'd have wasted loads of filament.…

Pimoroni | £13 / $14 | pimoroni.com We've covered Pimoroni's range of Pirate Audio boards before – Zero-size HATs featuring an on-board mini LCD and a choice of features and outputs. The firm has now launched a couple of even smaller audio DAC products in the form of super-slimline SHIMs – short for ‘Shove Hardware In Middle’! – that fit over Raspberry Pi's GPIO pins and stay put thanks to a friction-fit connector. You can even sandwich a SHIM between a Raspberry Pi and a HAT. The Audio DAC SHIM (Line-Out) features a stereo line-level output via a 3.5 mm jack, so you can hook it up to a hi-fi amp and speakers. There's also an Audio Amp SHIM with a built-in 3 W mono amp and push-fit connectors for…

Pimoroni | £26 / $29 | pimoroni.com Outputting sound is all very well, but what if you need audio input? Sure, you could always plug in a USB mic or sound card connected to a microphone. Alternatively, the Pirate Audio Dual Mic features two mini mics on either side of the mini HAT to capture sounds in stereo. The mics feature a SiSonic acoustic sensor, a serial ADC (analogue-to-digital converter), and an interface to convert the signal into the industry-standard 24-bit I2S format. They record sound with crystal-clear quality, with volume levels shown on the LCD, although the mics aren't that far apart so the stereo effect is limited. It could prove very useful for any project that requires audio input, such as a portable recorder or voice assistant. To…

RP2040 macro keyboard Using RP2040 for little macro keyboards is a fun thing that we've done ourselves – they're great as a sort of media control suite for streaming. With the added dials, we think it would be even better. rpimag.co/rpmacro153 E-Ink Weather Dashboard While perhaps a simple project, it's also very cool, and looks great. There's a great sense of satisfaction from making something like this well, especially when it becomes a useful display piece. rpimag.co/weathdash153…
