There’s a lot of buzz surrounding artificial intelligence-generated art – images created from text prompts by a machine-learning system known as a generative adversarial network – but it can be difficult to get excited about something you only ever see in your web browser. That’s where Alex Thiele‘s Portrayt comes in: A Raspberry Pi 3 Model A+, or any other model of Raspberry Pi with the 40-pin general-purpose input/output (GPIO) header and a network connection, mounted to the back of a Pimoroni Inky wHAT E Ink display and sat on a small wooden easel.

Throughout the day, software running on the Raspberry Pi sends prompts to the Stable Diffusion GAN and downloads the result for display on the screen. No user interaction is required. “You can interpolate from one prompt to another,” Thiele adds. “For example, you could interpolate from ‘barren tree’ to ‘lush tree’ over the course of some amount of images, and have it take 24 hours to finish the cycle. It’s fun to have something new to look at each time you look at the display!”

As of August 2022, the total global electricity usage for crypto-assets was between 120 and 240 billion kilowatt-hours per year. This exceeds the total annual electricity usage of countries such as Argentina or Australia. Let’s be honest, crypto mining consumes a ridiculous amount of energy.

Using a Raspberry Pi with a PiJuice and Notecard Learn, Rob Lauer created a solar-powered cryptocurrency “mining rig” with cloud-based reporting in a self-containing system – and shared it with the world. It’s not something that will make you rich, as the sheer computer power of a Raspberry Pi is not up to par with current crypto-mining machines, but you’ll at least go to sleep with a good conscience.

The free sheet music library IMSLP is a godsend if you’re a musician. It will provide you with more scores than you can ever play in your entire life.

Composer, conductor, teacher, and self-proclaimed “total geek,” Afryklund thought of a way to access the database right at his instrument, the piano. So he used an old Raspberry Pi and a cheap Dell touchscreen monitor to set up his browsable sheet music stand. Planned additions are handwriting recognition, playback, and an on-screen metronome.

In theory, you aren’t bound to sheet music – think of a project where a database can be accessible right at your fingertips without the need for a tablet or laptop.

“My mom recently bought me a Raspberry Pi for my 21st birthday and asked me if I could do something cool with it,” Amir Ali Hashemi, a student of artificial intelligence, explains. “I mean, I’m not just some AI novice, I spent three whole years of my life studying the subject, so I’d better be able to run a program on it.” The result: A YouTube channel that runs itself.

A Python program running on a Raspberry Pi 4 Model B, connected to the internet via Ethernet or Wi-Fi, pulls down popular posts from Reddit and runs them through a cloud-based text-to-speech engine – combining the output with music and visuals to automatically generate videos. These videos are then uploaded to a YouTube channel, all without user interaction – an interesting approach to content creation, but one which will certainly draw its share of criticism.

“I have been emotionally attached to this particular piece of radio since I was a kid,” maker Mizu Matejka explains of a VEF 206 transistor radio from the 1970s. “It was always playing behind my back every morning while having breakfast in our kitchen. Now it’s one the fewest things left from my childhood, making it something special to me.”

Being tired of using the now non-functional radio as a decoration, Matejka decided to give it an upgrade by replacing its innards with a Raspberry Pi 2 Model B (any other version would also work) alongside a 3W stereo amplifier, a potentiometer with RGB LED, rotary encoder, and a USB Wi-Fi Dongle, the latter only being required if not using a Raspberry Pi with built-in Wi-Fi support. The result is a radio that keeps the original’s aesthetics but connects to internet radio streams – a great blend of vintage and modern technology.

To call the Alpakka a “gamepad” is, perhaps, doing it an injustice: What Input Labs has created is a gadget that includes both digital and analog controls plus a pair of gyroscopic sensors – providing what the company claims are mouse-like performance in competitive games. “Having the performance of a mouse combined with the convenience of a gamepad,” the company promises, “you won’t have to make any compromise anymore.”

Inside the customizable 3D printed shell is a Raspberry Pi Pico microcontroller board, which has a high enough performance to drive the controller at 250Hz with ultra-low latency. The entire controller design is open source, including the 3D printable body – and the firmware includes eight profiles for different game genres, including first-person shooters and real-time strategy games.

This Ikea hack transforms any surface into a smart interface using a Raspberry Pi, a laser projector, and the new Android Things operating system from Google.

Rather than having every object in our home and office become ‘smart’, Lantern imagines a future where projections are used to present ambient, relevant UI around everyday objects. Opposed to a screen, when they’re no longer needed, the projected user interface simply fades away.

The smart lantern by Nord Projects is built around the concept of ‘channels’ – mini-apps that can be configured through a companion coding environment. It connects to online data feeds online and then displays a projected user interface.
