PWM3G Connections, Tuning & More Information

Listen to this video, all 10 parts, if you want to hear about this technology. Not a myth or a crime. Hear it from the man who is ahead of his field, from a recent Hydrogen Show. Also read teh Chris Patton interview on Bob B, a few years back on youtube. 2/09 Also read about his car on jack stands up to 60 mpg.

Many ask what is the difference between the Hex Controller and the PWM3G board? The Hex Controller has automatic tuning. (stays in tune no matter the variables : water temp changes, charged water changes, etc.) The PWM3G is manual tuning, safer, will produce about 4-5x's Faraday's law. (approx. 45 lters per minute) When temps change you may have to tune while in use. The PWM3G is given away to the public (minus no schematic) the Hex Controller is Bob's baby and only given away to friends that he trusts. The Hex Controller can also be very dangerous and up to 10's Faradays!, but one has to have full knlowledge of it's potential before using it.

The PWM3g pcb Circuit Board.
Version "G" boards hot off the press! 1-20-08
For larger image click on pcb board

* Please note ~ the "G" board has tricky soldering involved. It has 9, very tiny ceramic chip capacitors, that are soldered onto the bottom of the board. They are about a 1/16" long!

These tiny devices are manufactured for a special processing method that controls the heat and uses a solder paste in a very controlled heating atmosphere. If you are doing hand soldering work, it is very easy to overheat those tiny devices with a hot soldering iron. Overheating will cause them to get a hairline crack in the body of the ceramic. As tiny as these devices are you might not even realize this has occurred without a microscope.

Use a very low wattage iron and avoid applying heat directly to the body of the capacitor. You might want to use tweezers to hold the tiny device and first melt some solder on the metallic pad of the circuit board. Pit a dab of liquid flux on the just tinned pad also touch some to the end of the capacitor. Apply heat to the circuit board solder pad and hold the capacitor with tweezers letting it attach itself to the wet metallic solder. Remove heat as soon as possible and then apply similar considerations to the other side to attach it. Your best results will be with a nicely tinned soldering tip of the pencil variety. Use a damp sponge to keep the tip from oxidizing, wiping it before use. Use a tooth pic to apply the liquid soldering flux or get a flux pen. After soldering use some isopropyl alcohol and a small brush to clean off any remaining flux from the capacitor and the solder pads.

Order all the electronic parts right now
a pre-filled order form
from Digi-key.com

(Terry made this Digikey list available and ready to order for about $60.
New update on parts list above has 3 changes to this Digikey order
Note C1, C3 and C4 are different from this DigiKey list. Also R7, R8
and R9 are not necessary and can be replace with a wire jumper.
About $92 for all the parts for the PWM3f-HD with 3
heavy duty mosfets at $11.67 each.)

The only difference between the PWM3e & the PWM3f,
is that the holes for M1, M2 & M3 varistors are larger.
We still have "F" version at Hydrogen Garage Store.
We also sell the f-HD pcb board.

The PWM3f_HD board has larger hexfets Q1, Q2 & Q3
Larger hexfet holes and a larger aluminum heat sink block. The HD
was for the experimenters who were using 240 volts or Arc welders
to supply the high voltage for large 100+ plate cells, for water torches.

(the PWM3f board can be used just use an
offset heat sink from the pcb board)

Plate Preparation and Conditioning

The PWM3f& the PWM3g boards require a Toroid Coil, soon will
be available at Hydrogen Garage. (10/23/08) for $390.
You can turn to hand wind one. (takes time, about 2-4 hours) & you got to be good at it. If wound wrong, it may not work correctly.
You can buy the Iron Core from MicroMetals. The special
PTFE silver coated copper wire to wind your primary & secondary wiring,
can be bought from Steve at Apex Junior. The lowest price on silver plated Copper wire that you are gonna find.
