Natural kind of cellulose sponges are made out of wood or vegetable fibers. I know Trader Joe's here (https://www.amazon.com/dp/B008XLGDDQ/?tag=pfamazon01-20) imports them from France so you might find it somewhere in Europe or figure out how they make them. I think they match all your...
That output of 10mV is for moving magnet type coils, piezos give as high as 0.5 V and can directly drive speakers. The phono cartridge is a stock one on a Vibe turntable, a cheapo one and probably no brand. It's stereo so has two piezo elements (90 deg at each other and 45 with the cartridge)...
Hi,
I'm using a piezoelectric ceramic phono cartridge to produce high frequency displacements in the phono stylus. I'm driving it with a function generator that has an output of +-10 V sine wave . I connected the generator to a transformer that has a 1/10 reduction ratio to ramp up to voltage...
Is there a specific reason you want to use compressed air? It would be more inefficient than an electrical based system like a hybrid car. You can instead have somebody pedal an electrical generator at an optimum rate continuously, and divert some/all the output to the main motor or the battery...

Does this mean the swiss are making fake chinese watches?
I think there were workers in the basements working on the electrical connections and there was no flooding at that point (maybe within couple weeks). Then one day ( i can't remember the exact date), they found some water about 30 cm deep, and two or three workers got irradiated through their...
You are a new poster here and i understand you haven't gone over the thousands of posts. All the things you mention were discussed here a while ago and debunked basically.
