Begin experimenting quickly by watching how to videos! 

Watch a 3 part video on how to make an HHO device with stainless steel pipes.

Watch a 5 part video and supplemental videos on how to make an HHO PWM device.

Watch a Video showing a breadboard prototype that I made. The design is an easy to build MOSFET IRF510 and 555 Timer Pulse Width Modulation (PWM) Circuit demonstrating basic hydrogen production. Begin experimenting right now. The parts are easily obtained from Radio Shack and The Home Depot.

VERY IMPORTANT! These plans are for entertainment purposes only. I have not built or tested these plans. I intend to do so in the future. If anyone has built these and seen them work to produce hydrogen, please contact me at the bottom of this web page.

After you have seen and built the more basic circuit as described above, perhaps you would like to build the circuits below. Build a hydrogen generator with an NE555 timer, TC4420CPA MOSFET Driver, MOSFET IRF510, LM741 OP AMP, CD4069, resistors, diodes, and other associated parts. (not IFR510 but IRF510 - $2 at Radio Shack)

Hi, my name is mike. i bought the plans you have posted here, i liked the entire book it was very informative. i do not like the actual generator itself, …

Your circuit on the lm741 Not rated yet
Build it any way you like but the LM741 circuit does not work...! I'm trying to find someone who can tell me why. Contact me on ogkyusa@yahoo.com if …
