I wouldn't be too dismissive.

- triceratops 2y agoIt's a prototype.
- fallat 2y agoWhat? I went on Aliexpress and found a 40KHz transducer for $40. You can 3D print the attachment, can't you?
- iancmceachern 2y agoA woofer from AliExpress is not a speaker with amp you can use for University level audio work. I expect they used something like these: https://www.emerson.com/en-us/automation/branson https://www.emerson.com/en-us/automation/branson You cannot 3d print anything in the ultrasonic chain, they need to be machined from specific metal, that's why the horns cost so much.
- parineum 2y ago> A woofer from AliExpress is not a speaker with amp you can use for University level audio work. We're talking about coffee here...
- iancmceachern 2y agoExactly! Wars have been fought over coffee, people regularly spend thousands for coffee machines. There are entire companies that exist just to cater to this market. Me, I'm a tea guy.
- JoBrad 2y agoA wholly different set of wars
- fallat 2y agoI looked up "transducer" and it seems to be what you'd need. But! You seem to have found where I was wrong: the horn. The horn seems to be the actual expensive part here. They could start a business I guess selling these en-masse. If anyone has any ideas how a maker could create this within reason please reply.
- iancmceachern 2y agoYou can't really sell them in big quantities because they're typically custom to the task. They need to be custom shaped for each application.
- srmatto 2y agoPortafilters are made in mass so you could make horns for common portafilters.

- bongodongobob 2y agoThey make ultrasonic jewelry cleaners for $75 that should work just fine. You're referencing something that is intended to be used with hundreds of gallons of water.
- iancmceachern 2y agoI'm just talking about the paper. If they had referenced what you mention I would have referenced that
