This looks very cool!
I've just been looking at your github repository, you mention you use the HV7360 chip to generate the ultrasound pulse.
I'm slightly confused by the datasheet for this chip, am I right in thinking you supply +/- 100V to this chip? If so, what are you using to generate that voltage out of curiosity?
(I have a ~2MHz ultrasound transducer which I keep meaning to play with, to attempt to measure liquid density, so your project is very interesting to me!)
- kelu124 11y agoHey there. Indeed, we supply HV to the pulser. Integrated is a recom dc/dc converter. Alternatively, for a DIY approach, you can as well work with something as in http://echopen.org/index.php?title=Analog_Parts_%28Farad%29#High_Pulse_Voltage http://echopen.org/index.php?title=Analog_Parts_%28Farad%29#... - for HV and pulser.
