Here is a Web App I made that can simplify this process if you wish to experiment. http://typeright.social/neurophone/
Hey Joel thank you for making web app I have struggles with making the circuit and connecting everything together , can you post few crude images of youre neurophone so I can replicate it based on image , im new to electronics so it would be so much easier to do it based if few images , thanks !

These are technical specification of the buzzers. Is these OK?
I found this piezo ultrasonic transducer in local store. I think this is the right one? What you think? https://vikiwat.com/product/19807/ultras...mm.en.html Also what kind of transformer is good to use, i mean 12 to 12 volts? Or 220 to 12?

As far as transformer goes an "isolation" transformer would work best. Any AC transformer should also work well, Typically, a high impedance device like a piezoelectric buzzer should be connected to the higher voltage output of the transformer. This is because a high impedance device requires a higher voltage to drive it than a low impedance device.

Hi, is that the correct setup? Can you see the images? Minus of the piezo is open or connect with ground of soundcard? No extra power supply for transformer? Only from sound card?
https://youtu.be/aje_lGmC_wY i made a video. I try with common ground for transformer and piezo minus, it goes stronger sound. Should there be sound? |
