Information

What is it supposed to do?

The aim of this echOmod is to get the mechanical movement of the piezos. Salvaged from a former ATL10PV.

How does it work: block diagram

About the module

Pros

  • Simple to use

Cons

  • We have removed the position system : we don't have the encoding system
  • Tough to find a old 10PV probe

Constraint and limits

  • Motor is a 12V... doesn't move below 10V ... using 300mA@10V -- we could use a 5V to 12V DC/DC boost similar to this one. Could feed onto the 5V entry and leave on the 12V output. Can be found on Gotronics and such. Or the 12V could be delivered to the board itself.

  • 3 piezos are fixed frequency

  • Oil to be found to replace lost one =) Feeback: linseed oil seems good !

  • Tested with murgen : not really pratical to use, maybe to be replaced with a simple 3MHz probe. Read the full test on murgen's repo.

  • It seems that the noise previously seen with the bitscope was due to the computer! Not to the bitscope.

  • We have found an interesting doc: the ATL manual for the ultrasound machine - and specs for the whole set of transducers -- found here
