Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/ ➠ ➠ ➠ In this video, I showcase my custom-designed, portable audio signal generator. Built to run on batteries, this tool eliminates earth-ground referencing issues that plagued one of my previous projects.
Using traditional signal generators and scopes, I accidentally created ground loops that shorted parts of my circuit—this generator solves that problem completely.
Inspired by online designs but tailored to my personal needs, this simplified signal generator is compact, easy to use, and highly adaptable. The PCBs are available in the PCBWay share section, so you can customize it to your requirements and avoid similar challenges in your own projects. I also created a custom 3D-printed enclosure to make it fully portable and practical.
Watch as I explain the design, build process, and demonstrate its functionality in real-world applications.
I’ve provided everything you need to build your own, on my Google Drive, including:
✅ Gerber files
✅ Schematic
✅ 3D print files for a custom enclosure
