Raspberry Pi Boot from USB

In this Raspberry Pi boot from USB guide, we will be showing you how it is possible to boot your chosen operating system from a USB storage device instead of the standard SD card.

We will walk you through the steps required to activate the USB boot mode in the one-time programmable (OTP) memory. You will need a newer Raspberry Pi to complete this tutorial correctly (see below).

Highly Unofficial “Raspberry Pi 3B Mini,” Customized for TPCast, Appears for Sale

Cut-down single-board computer packs the same power as a Raspberry Pi 3, but in a more compact footprint.

An unusual customized Raspberry Pi variant, designed for use in video streaming applications, has surfaced for sale — and it’s been dubbed, extremely unofficially, the “Raspberry Pi 3B Mini.”

PicoLight – Minimalist Light for Product Shots

PicoLight is a minimalist adjustable light for low-light photography, based on the Raspberry Pi Pico.

One of the activities I really enjoy while working on a new project is documenting it. I love getting creative while taking pictures of the process and of the final products. A thing that has been really handy in this process is an adjustable studio light, which I use to add a bit of colour to the background (that’s why most of the pictures in these tutorials are purple hehe).

PicoLight is a smaller version of a classic studio light that is useful for playing with colours in low-light shots or for coloured shadows photography.

3D Printed “What If Machine” Plays Every FUTURAMA Episode

Reddit user Remoheadder has 3D printed the infamous “What If Machine” from Futurama and hooked it up with a Raspberry Pi 3 to play every episode of Futurama. You can check out a video of it working on Reddit as well as a how to guide for how it was put together. Inspired by Bubba447 and their working Simpsons TV, Remoheadder took a lot of the code from that build and tweaked it to fit their own project. One of those tweaks? Adding a long hold option to the button to bring up the Hypnotoad channel. All hail Hypnotoad!

UCTRONICS’ PoE HAT Mini Adds Power-over-Ethernet to a Raspberry Pi in Tiny Footprint

Designed to leave most GPIO pins free and not block the SoC, UCTRONICS’ PoE HAT Mini is an interesting add-on for Power-over-Ethernet.

UCTRONICS has launched a pair of alternatives to the Raspberry Pi Power-over-Ethernet (PoE) HAT, and while one is a near-copy the second is considerably smaller: the PoE HAT Mini.

The original Raspberry Pi PoE HAT was unveiled three years ago alongside the Raspberry Pi 3 Model B+. Designed to simplify cabling for remote installations, the add-on connects to the Raspberry Pi’s general-purpose input/output (GPIO) header and a second dedicated header found only on the Raspberry Pi 3 Model B+ and later Raspberry Pi 4 Model B, and allows the device to be powered using an Ethernet cable and a compatible switch or power injector.

This Giant Display Uses 1,152 Seven-Segment Digits to Show Graphics

Divided across a matrix of 7,200 segments within 1,152 individual digits, this complex display is a unique way to draw images.

Ordinary displays typically feature a matrix of LEDs or liquid crystals that illuminate in specific patterns to generate images. On the other hand, the classic seven-segment module uses, as the name implies, seven LED segments that light up when power is applied. Some modules even combine several of these together and sometimes add decimal points. Maker Chris Combs had the idea to combine these two display technologies together by using the individual segments within each module as a pixel to draw a large image within a massive display. This gives a very retro, yet futuristic, aesthetic that is hard to replicate otherwise.

Pi64 – The Pi64 is a Raspberry Pi 400 that thinks it’s a Commodore 64.

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.

Les Wright’s DIY Raspberry Pi Spectrometer

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.

Raspberry Pi and ESP32-S2 Team Up for Mutantc_V4

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.

This Raspberry Pi Pico-Powered Compact Keyboard PCB Breaks Unused GPIO Out to 3.5mm Jacks

Designed to make the most of the RP2040 microcontroller, this clever compact keyboard includes a rotary encoder and two expansion ports.


Reddit user “stewartd430” has designed a Raspberry Pi Pico-powered compact keyboard, complete with an expansion port for adding extra hardware to the microcontroller’s general-purpose input/output (GPIO) pins.

“I designed a keyboard PCB for the Pico,” Stewart explains of his project, which builds on earlier efforts including a simpler 20-key macro keypad driven by the same Raspberry Pi Pico board with RP2040 microcontroller. “65 percent layout, with 15 added macro keys and rotary encoder.”
