I’m making good progress with my spectrum analyser project. Here are a couple of photos that show my first hardware build. I still have a few iterations of the PCB design to go, and plenty of coding, but I’ve solved the main engineering problems. I’m pretty confident that this device will make it out of the lab and into the real world. Hopefully I’ll soon be have a small number of “beta test” devices for people to play with. Let me know if you’re interested in joining the test program.
