I've got a new dangerous part to experiment with, a Flyback transformer.
As you can see in the schematic we do have a few pickup coils to choose from...guess I could use to lowest Vpp coil. In the sheet we see the type of output pulse .
Could not find a detailed data sheet, usual PHILIPS parts data sheets are difficult to find.
Don't know if this part works on 230V...must inspect the circuit board were it comes from.
It's kind of dangerous to connect it to mains.

br,

don't do it!
flybacks are normally driven by 12V-18V, if you use a square wave the voltage generated will be enormous, don't use 230V!

Don't worry, haithar. I'm not connecting 230V.

outlawstc, I like the vice. what about taking the knob off and replacing it with a pulley. then belt drive it to the top of the cell.

yea somthin like that.. i think it would be more wise to find some type of bearing seal  and send it right out the side of the cell from the bottom.... i wanna be able to seal the unit and i think having a sealed bearing under water is smarter due to the density of water compared to gases.. i think you can create a more reliable seal and a safer one in the water zone of the cell rahter then a spot where explosive gases reside.

Look at how the older faucet valves were constructed with seats and washers.  Usually there's an o-ring on the shaft where there is a groove and in addition graphite packing (looks like black rope) and packing nut that slides over the stem and screws into the valve body.

From what I can tell Stan's is geared and is adjusted from the top but it would probably have a similar construction to prevent gas from escaping.  It's easier to attach a valve construction to a flat surface than it is to a curved surface.

Regards and Happy New Year,
Andy

Stans plate cell used a shaft down through from the top,and had string wrapped around this shaft in two plces top and bottom.Then the ends went through the one fixed plate,and one end tied to the  moveable plate, then the other end went through the moveable plate through a block on the other side and back through the block, and tied onto the moveable plate from the opposite side as the first end.Hope this makes sense.
Also there were several wraps of string around the shaft,and it was tied to it as well.So there was wraps above and below the tied point, wrapped all in one directions.
