any homemade ultrasonic homogenizers? I'm looking to dabble with making graphene via water/heptane interface barrier

i've looked into them before to do cell lysis for protein recovery, but I didn't find much at the time. Recently I saw some page talking about making your own piezo positioner, and I think it was talking about sourcing pizeo ceramic then adding their own electrodes on.
<_Sync_>
although the drivers that come with them are suuuuper dangerous
<chris_99>
dangerous how?
<SpeedEvil>
mains isolation
<SpeedEvil>
Or lack
<chris_99>
oh heh
<chris_99>
could you do ultrasonic welding with those i wonder
<SpeedEvil>
'yes'
<SpeedEvil>
with a suitable horn
<chris_99>
is the horn essentially just plastic or whatnot to focus the beam
<_Sync_>
alu mostly
<chris_99>
aha
<SpeedEvil>
It's an internal focus
<SpeedEvil>
the ultrasound bounces around internally to the metal - not externally

I was not planning on making the transducer, just the powersuppply/singla generator (as the chinese ones look like garbage) and maybe the acousti/ultrasonicc horn from some machine shop (440 stainless steel I think was listed as a common material used for that)
<_Sync_>
simulating the horn is an art tho
<Noxz>
eh, just find a patent or dimensions in some book and copy them ;)
<Noxz>
I dont want to desgin an ultrasonic machine fromt he ground up, I just want one on the cheap
<_Sync_>
well
<_Sync_>
the thing is, the chinese ones are not made to be coupled into a sonotrode
<Noxz>
tranducer or signal generator?
<_Sync_>
the transducers
<Noxz>
the transducers with a scre terminal or whichever is capable
