Innovative Laser Control System Featured in Make 4/25

A new 3D-printed laser control system is set to revolutionize how tools and items are located in workshops. This innovative project is detailed in the latest edition of Make magazine, issue 4/25, where readers can learn how to construct, program, and operate the system effectively.

As workshops accumulate a wide range of tools and materials over time, maintaining an organized space can become challenging. While a sharp memory is beneficial, implementing a systematic approach is crucial for ease of access. The previous issue of Make introduced a solution for managing small parts using app-controlled sorting boxes that illuminate to indicate their contents. However, this new endeavor addresses the issue of locating larger items stored on shelves, in boxes, or in various other places.

Instead of opting for a fully wired LED solution, the Make 4/25 presents a more user-friendly alternative: a remote-controlled device equipped with a laser pointer. When installed on a ceiling or wall, this device can precisely indicate the location of specific tools or items hidden in the workspace.

The article provides a comprehensive, step-by-step guide on recreating this device, from its assembly to programming and smartphone control. Those who have already utilized the smart storage boxes from the earlier issues can seamlessly integrate this laser control system into their existing setups or apply the knowledge gained to other projects. The design encourages creativity and efficiency in organizing workshop spaces.

Additionally, the magazine showcases another intriguing project: an automated feature for Spotify users working in noisy environments. Many makers enjoy listening to audiobooks or podcasts while operating loud machinery but often face interruptions that disrupt their listening experience. The Stopify project, developed by one of the contributors, allows Spotify playback to be paused automatically when excessive noise is detected. Utilizing an ESP32-based setup, the system employs a microphone and Fast Fourier Transform (FFT) technology to identify disruptive sounds, pausing the audio playback via the Spotify API. Once the noise subsides, the system resumes playback, providing a seamless listening experience.

The current issue of Make is available both online and at kiosks, with subscription options that allow readers to receive it directly at home. It can be ordered as a print version or PDF through the Heise Shop, with free shipping available until August 8. For those who prefer a digital format, the magazine can be accessed via apps for iOS and Android, with the table of contents also available online.
