John Park’s CircuitPython Parsec: LCD Character Marquee Scroll
John Park’s latest project showcases how to create a scrolling text marquee using an LCD Character display with CircuitPython. By utilizing the `move_left` and `move_right` commands, you can easily make text scroll across the screen, which adds a dynamic element to your projects.
Running local LLMs on the Arduino® UNO™ Q board: a practical guide
The article discusses running local large language models (LLMs) on the Arduino® UNO™ Q board, which combines a Debian Linux environment with the Arduino hardware ecosystem. This setup allows you to explore the integration of LLMs into embedded systems, providing a way to utilize language intelligence close to the data and devices they interact with. Unlike traditional cloud-based AI, these local models are tailored for specific tasks, enhancing functionality without unnecessary complexity.
You can 3D print this amazingly complex turbofan jet engine model
A new 3D printable model of a turbofan jet engine is available, allowing enthusiasts to explore how these complex systems work. Inspired by the CFM56-5 series engines found in Airbus A320 jets, this model balances accuracy and practicality for 3D printing. It comes in two variations: a complete engine with panels that can be opened to reveal its inner components and a turbofan assembly that provides a clear view of the core mechanics.
Dadlexa: The No-AI Smart Speaker
Sean Clark created Dadlexa, a unique DIY smart speaker that relies on human intelligence rather than artificial intelligence. When his son asks a question, the audio is sent to Clark’s phone, where he responds, and the answer is played back through the speaker. This approach allows for a more personal interaction between parent and child, contrasting with typical AI-driven devices.
This Electronic Business Card Visualizes Audio; Demonstrates Skillz
Alex created an innovative electronic business card that visualizes audio, turning a typically mundane item into something eye-catching and functional. The card features an onboard microphone that captures audio, displaying real-time frequency levels across an 8x5 grid of RGB LEDs. Alongside the audio visualization, Alex's contact information, including QR codes for his LinkedIn and portfolio, is printed directly on the card.
Million-Dollar PCBA Precision for Just $200
MagmaBow, a YouTuber, has developed a DIY pick-and-place machine for circuit board assembly that mimics the precision of high-end industrial equipment but at a fraction of the cost—just $200. This machine is designed to help makers keep up with the trend of smaller electronic components, which are becoming increasingly difficult to work with manually. By combining human operation with automated processes, it offers a practical solution for hobbyists.
GPS Has a HUGE Problem… That We Can Fix?
This video takes a critical look at the limitations of traditional GPS technology, particularly its lack of precision. The creator builds a small tank robot to demonstrate the shortcomings of standard GPS, showcasing how it can lead to inaccuracies in navigation and positioning.
