    3d Ultrasonic
Click For Summary
The discussion focuses on an Arduino-based project featuring three main functionalities: a virtual touch screen for remote control, a 3D ultrasonic sonar with a range of 3 meters and a 50 fps update rate, and precise distance measurements down to 12 micrometers. The project utilizes FFT in its software and incorporates four HC-SR04 ultrasonic sensors to achieve high measurement accuracy by extracting the phase of returning ultrasonic waves. Participants clarify the terminology, noting that "sonar" is more appropriate than "radar" for this application, as sonar uses sound waves. The conversation also touches on the broader applications of ultrasonic technology, although most examples cited are industrial or military in nature. The project is positioned as a unique hobbyist endeavor with potential for further exploration and development.

I'm working on arduino based project, that actually can perform 3 features:

1. Virtual Touch Screen, for remote control purposes big screen TV, projectors, public display, or for interactive games
2. 3D Ultrasonic Radar, small range - 3 m for now, but real time with update rate 50 fps;
3. Precise distance measurements , down do 12 micrometers.

FFT is the major part of software application running on arduino DUE (cortex-3 , ATMEL SAM3X8E), plus 4 very popular ultrasonic distance sensors HC-SR04. Extracting the phase of returning ultrasonic wave, great precision in distance measurements possible.

More details on the blog page:

and two demo video clips on youtube channel:

Opinions and suggestions are welcome.

Sounds like an interesting project. BTW, I changed "Radar" to "Sonar" in your thread title. Radar uses radio waves, and Sonar uses sound (or ultrasound) waves. :smile:
 
There's a lot of research on that subject. They use it for refueling of sodium cooled reactors because you can't see through sodium.
A friend did electronics work for Bechtel , making high powered drivers for the transducers.

A quick search turned up lots more applications than i could have imagined:

You're on to something there. Have fun !

Agree, I missed this out. Same time sonar term sounds too specific, related to underwater localization. Tracking object in the air brings radar to mind

True, but all of them industrial or military. I don't know any research on small, "hobbyist" scale, with a budget < 100$.
New video posted, radar, hmm, sonar relaying a data to android application.

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
