Exchanging physical stuff is supercool. Why are people not stuck with it? (Maybe because it's not cool to pay your new car with 1.5 million carrots.) I would like to have a cool logodesign for my DIY stuff, but I suck at drawing and a good friend of mine, who is a professional designer, wants to have a very specific effectbox for his guitar, but has no soldering skills. So why not "execute" a classic exchange of these things? I would never pay his hourly wage. This is why I bought this DIY kit (You have to order the knobs extra!!!), waited for delivery and stored the kit in my desk. It's like wine: Store it and wait. To be honest: I had less time and enough other $things to do.
The idea to build an EMF-Detector came while i fucked up my last project partially. While i was soldering the pcb i did a mistake while connecting a wire. This gave me a broken signal of a buttonstate (switching from 0 to 1) switching back and forth. I fixed that, but wanted to know exactly why this happens.
Result: When you don't connect the input of the controller to ground, you are not able to set a solid state and the µController starts to interpret everything what he gets. In this case it reads electromagnetic fields. So why not digging further into this and build a gauge to have a look on which devices are having a nice electromagnetic party?
