hydrogen fuel cell electrode
hi here is an easy to make 7 stack stainless electrode unit made up out of 316 stainless steel ice cream bowls silicon sealed together so you can adjust for a minimum gap.i now need to buy or advice to make a pulse voltage generator and to get a ultrasonic frequency generator set at 42712.2hz this splits water and may do it without any electric or electrodes so if anyone can try that as well as do not have equipment it also needs a amplifier and transducer

Medical VNR: Ultrasound-Assisted Liposuction Trials
PRVIDEO.TV/MARSHALL THOMPSON
310-403-2507
New reserch in medical devices and technique takes place 24/7. This Video News Release invites interested people to participate in a unique Ultrasound-Assisted Liposuction Trial. The new technique uses a liposuction probe with an ultrasound transducer positioned on it's tip.
The new wand or cannula actually liquifies the fat, making its removal easier with less scarring and a shorter healing time.

Theremin controlled by ultrasound rangefinder
Two 40 kHz ultrasound sensors are used as a rangefinder with a soundcard running at 192 kHz, and Matlab. The distance between the transducers controls the pitch of the note.
The video is based on a project done at the Group for Digital Signal Processing and Image Analysis, http://www.ifi.uio.no/research/groups/dsb/, Department of Informatics, University of Oslo in the course INF3460 - Project in acoustics and signal processing,

Acoustic levitation
Levitation of an acrylic disk 5mm thick x 10mm in diameter via acoustic ultrasonic radiation from a piezoelectric transducer in water. The levitation is due to the powerful acoustic radiation force, and can be manipulated to rotate the object at high speeds. It also works in air

Fiery Fun with an Ultrasonic Cell Disruptor
Cassie and I had a cell disruptor, a candle, some fire, and lots of time on our hands.
The ultrasonic cell disruptor is an ultra-high frequency sonic tone generator, pumping out 22.5KHz waves with several sub-frequencies from a small, wand-shaped transducer.

The ultrasonic transducer TX/RX
This is a little circuit I came up with while bored one day. I send a high frequency pulse from my receiver, and it receive to about 12 meters away and changed into a 5v digital signal.

22nd Week Ultrasound
This is a video of my son at 22 weeks. I actually filmed this with the transducer. At the end, I bob the transducer up and down making his face move towards the screen. You can see my wife laughing.
