  • Hi, I'm Toon from the original Instructable. I tried the teensy audio board, but In this case it was not very useful because you only need the sound that travels for one meter. So no need for SD cards. And I needed the highest possible sample rate. The horizontal resolution is limited by your sampling resolution. For one meter you need to record sound for 2915 microseconds, and between every ADC readout you need to pause for 15 micro's, I maxed out at 112 samples / meter. It was fun to make. I'm working on a linear rail version, but going really fast to show the soundwave is not an easy task. But then again this project doesn't make much sense either. It is just for fun and practice.

No public wish lists :(
