Quick video of a home made Hoffman Apparatus I've been tinkering with... I'm trying to find a cheap and easy way to generate hydrogen so I can do some interesting new experiments.

How many volts AC are you feeding to the diode? Thank you for posting.

Cool experiment. How does it scale - are you planning to make a bigger one?

Thanks for the video, very informative. Do you mind telling us where you got the "H" shaped tube?

Yeah a bit bigger... my plan was to use the hydrogen and oxygen in my sputter chamber and do a few other experiments...

You should let the system run for a little while before starting the flame. The hydrogen generator should have time to purge the line of air otherwise you will have a hydrogen/air mixture that first hits the ignition source. This can flash-back into the output line and into generator. You're volume is so low that you would be lucky to get much more than your corks popping out, but it's a good habit.

would have been better to get a pre-mad hoffman app.
