The Raspberry Pi was a truly exciting computing device for me during my college years. It could run a full-fledged modified desktop and serve a crucial role in small IoT devices. However, I didn’t like the idea of pairing it with a breadboard, connecting wires, figuring out resistors, voltage, and the electronic aspects of it. I preferred software-focused projects that could leverage the available ports and hardware to build something purposeful with a Raspberry Pi and another gadget or device.

I’ve again jumped into the SBC realm, and this time I have multiple SBCs, including a Pi and Radxa boards. Still, the idea of innovative, non-soldering projects is the one that I try the most. Let’s discuss a few useful Raspberry Pi projects that don’t force you to wield the soldering iron (or even buy one).

Convert a Hi-Fi speaker into an audio streaming behemoth

Add wireless playback capabilities

Bluetooth-enabled, wireless streaming speakers with powerful software support, such as Alexa, are now common. But analog Hi-Fi speakers ruled the world a decade before, and I had one of those lying around. The connection options were very limited, with AUX as my only audio option. So, I turned it into a streaming speaker with Bluetooth capabilities with a Pi Zero 2W and moOde Audio OS.

But don’t you need a DAC hat for that, or physically figure out a connection for an audio jack? No, I didn’t need all that because I had a USB Type-C audio jack. I regularly use it with my Samsung phone, which made the horrible decision of skipping the 3.5 mm audio port. I simply flashed the moOde Audio OS on an SD card, plugged it into my Pi Zero 2W, and had a web UI available for configuration.

MoOde Audio OS is the brain of the project, as it enables you to select between HDMI and other USB outputs. I connected the DAC to the Pi and configured it as my primary audio output port in the OS settings. I also enabled Bluetooth, which now gave me two options to play my favorite tracks.

I can use the moOde interface to play any audio track by uploading it beforehand. Or, I can simply connect to the Pi’s Bluetooth and direct it to play songs via the old speaker set. So, I saved the trouble of soldering a Bluetooth dongle to the speaker system or adding an audio port to the Pi.

AI-art generator display

Create a unique artwork collection

Pi and a screen can produce some fantastic SBC projects, such as a retro gaming station, a magic mirror, or a dashboard. But what about incorporating something more creative into your home or office space to liven it up? All you need is a seven-inch e-INK display with a fairly cheap Pi Zero 2W.

You don’t need to worry about complicated connections as the Pi’s GPIO headers snap directly onto the E-ink display. All you need to do is connect a micro-USB cable to power the setup and direct it to display art.

On the software side of things, you need to set up the InkyPi and then use a custom AI art generator plugin that leverages OpenAI’s API key. Like most self-hosted Pi setups, you can interact with the web interface to tell the Pi to generate AI art or even quotes or jokes.

Since the art depends on your prompt, you can try multiple ideas to generate an image to your liking and display it. OpenAI’s DALL-E handles all the image generation heavy lifting, and the plugin configures the image to display correctly on the E-ink screen.

Energy frugal desktop

A computer for basic needs

The hopes of using Raspberry Pi as a desktop replacement grow stronger with each iteration. Raspberry Pi 5 can comfortably pull off this feat without a problem, and it's a cool project that only needs a USB hub and peripherals to accomplish. You can use it as an additional PC, or build one for kids so that they don’t mess with your main PC.

You can connect an old LCD monitor to the Pi's HDMI port and connect a keyboard, mouse, and other peripherals to the available ports. Using an NVMe SSD with the Pi 5 enhances the overall experience, but it requires an additional HAT to function properly.

Barring the AUX port, the Pi 5 has everything that you need in a low-end PC. You can use Bluetooth to pair a speaker or connect a USB DAC to a soundbar via the Pi. The best part is that Pi 5 can run a variety of operating systems, ranging from the official Raspberry Pi OS to multiple other feature-rich Linux operating systems.

Even Windows 11 works on the Pi 5, but I recommend using the official Raspberry Pi desktop version for optimal performance.

Remote downloading device

Control downloads from anywhere

I built a remote download Raspberry Pi with the Pi Zero 2W sometime back and use it even now. It’s an extremely energy-efficient device that manages downloads as needed. The setup’s extremely simple, as I use the GUI version of the Raspberry Pi Desktop OS (32-bit) with RealVNC.

I prefer RealVNC over Raspberry Pi Connect for several reasons, and I appreciate the level of control it offers. I can remotely connect to the Pi via its app and then paste links into JDownloader2, which stores everything on an external SSD connected to the Pi.

It frees up my main PC for downloading tasks while also acting as a remote file access tool via File Browser. RealVNC also offers an option to transfer files over the network to the main PC, which I can accomplish without ever touching a GPIO header or building circuits.

Media streaming server

Your personal video collection is a tap away

Building a media streaming server with a Raspberry Pi can make all your personal content accessible on your local network, as well as outside it. I use a combination of Jellyfin and Tailscale to run a media streaming server that is accessible from both my phone and PC.

It not only serves as a great time-killing alternative to paid streaming, but also makes my files available on the network. Even if I’m traveling, I don’t need to carry the storage drives; I can just download the required media if the connection is wonky and unfit for direct streaming.

Adding Tailscale enables access to the server from outside the network, and you only need to install and log in to the account once. After enabling Tailscale, only the devices with the same Tailscale account and connection setup can access my media files, ensuring robust security.

Escape the gruesome soldering

These were the five immensely useful Raspberry Pi projects that skipped the electronic tinkering needed to integrate additional components with the Pi. You can utilize the available ports to convert the Raspberry Pi into a dedicated role, such as a music streaming device, file management system, spare desktop, or a stunning digital photo frame that displays custom artwork.
