Hello guyz! It is not a question, I just wanted to "boast" a little bit about the prototype of the ultrasonic device for the blind. It uses two boards, the top one is an adau1701 based computer (can I call it a computer since it computes?) and the bottom one - a power supply with voltages up to 400v and high voltage amps.
Cannot believe it is done!!
The first time I have done something except a music score.
The scale is in millimeters.
