Our Top 10 Picks from Showoff Saturday (July 26, 2025)
This month's showcase was a testament to dedication and skill. After sifting through hundreds of incredible submissions, we've curated a list that represents the diverse talent within the DIY community.
1. The Automated Hydroponic Garden Wall
Kicking off our list is a stunning fusion of nature and technology. A user showcased their floor-to-ceiling hydroponic wall, capable of growing herbs and leafy greens indoors year-round. The system is fully automated using an ESP32 microcontroller, which manages water pumps, nutrient levels, and a custom-tuned LED grow light schedule. A sleek web interface allows for remote monitoring and adjustments. It’s a perfect example of a practical, sustainable, and beautiful home improvement project.
2. "Aurora" - The Interactive LED Art Installation
Art met creative coding in this mesmerizing project. "Aurora" is a large, wall-mounted panel with hundreds of individually addressable LEDs that react to sound and motion. Using a microphone and a proximity sensor, the installation creates flowing, aurora-like light patterns that shift and dance in response to music or people walking by. The creator shared the open-source code, making this high-tech art piece accessible to other makers.
3. Hand-Crafted Walnut & Epoxy Resin River Desk
A true masterpiece of woodworking, this project had the community in awe. The builder sourced two live-edge walnut slabs and joined them with a shimmering, deep-blue epoxy resin "river." The level of craftsmanship was impeccable, from the perfectly sanded surface finished with Rubio Monocoat to the custom-welded steel legs. This project highlights the timeless appeal of traditional skills and a keen eye for design.
4. The Self-Hosted "Life Dashboard" on a Raspberry Pi
For the data-driven individual, this home lab project is a dream come true. A tinkerer built a comprehensive personal dashboard, running on a Raspberry Pi and displayed on an e-ink screen. It pulls data from various APIs to show a daily calendar, to-do list, local weather, stock prices, and even real-time public transit information. It's a powerful demonstration of how a simple, low-cost computer can be used to organize and streamline daily life, all while maintaining data privacy through self-hosting.
5. The Custom-Built Retro Arcade Cabinet
Nostalgia hit hard with this incredible retro arcade cabinet. Built from scratch using MDF, the cabinet features classic arcade artwork, authentic joysticks and buttons, and a crisp LCD monitor. It's powered by a Raspberry Pi running RetroPie, emulating thousands of classic games from the 80s and 90s. The attention to detail, right down to the light-up marquee, makes this a show-stopping piece for any game room.
6. A 3D Printed Mechanical Orrery
This project is an engineering marvel. An enthusiast designed and 3D printed a fully mechanical orrery—a model of our solar system that accurately depicts the relative positions and motions of the planets. With a complex system of gears, all driven by a single hand crank, the model is both an educational tool and a beautiful kinetic sculpture. The creator spent months perfecting the gear ratios, a testament to the power of modern 3D printing for creating intricate mechanical devices.
7. The "Smart" Coffee Roaster Conversion
Combining the love of coffee and IoT, a maker converted a simple popcorn popper into a sophisticated, profile-driven coffee roaster. By adding a thermocouple for temperature sensing, a motor controller for bean agitation, and a microcontroller, they can now precisely control the roasting process. The system connects via Bluetooth to an app that graphs the roast profile in real-time, allowing for repeatable, café-quality results at home.
8. Hand-Sewn Leather Messenger Bag
Stepping away from electronics, this project showcases pure, traditional craft. A skilled leatherworker shared their process of creating a stunning messenger bag entirely by hand. From cutting the full-grain leather to saddle-stitching every seam with waxed thread and setting the brass hardware, the entire process was a masterclass in patience and precision. The final product is a durable, timeless piece that will last a lifetime.
9. AI-Powered Bird Feeder Camera
A fantastic blend of nature and artificial intelligence. This project uses a Raspberry Pi with a camera pointed at a bird feeder. A custom-trained machine learning model (using TensorFlow Lite) identifies the species of each bird that visits. When a new bird is detected, it snaps a picture, logs the species and time of visit to a local database, and even sends a notification to the owner's phone. It's a wonderful way to engage with local wildlife and a great entry point into practical AI applications.
10. A Modular Synthesizer from Scratch
For the musically and electronically inclined, this project was a symphony of circuits. A builder designed and created a Eurorack-style modular synthesizer from the ground up. This involved designing PCBs, soldering thousands of components for various modules (oscillators, filters, sequencers), and building a custom case. The result is a unique, personal instrument capable of creating otherworldly sounds. It's the ultimate electronics DIY project for any audio enthusiast.
