Electrolyzer Design Modifications: 

We tried doing a modified Smack. We used 8 plates, 4 cells. The plates are 3"x10", instead of 3"x5". We don't have solid reports on LPM yet, but at 30 amps, the booster does not heat up even after 30 minutes of use. The water will be just as cool as when we put it in. On the other hand, a true Smack Booster that our friend has, while putting out slightly more gas, heats up like crazy in the less time and the same amps.

Electrolyzer Problems: 

Not producing as much gas as it should, however, we have not cleaned or really sanded it, so we will see what happens after doing that.

Electrolyzer Problems: 

Leaks due to connections not sealing. Need new grommets.
Getting the stack connected to a power source without shorts.

Final Electrolyzer Notes: 

Figured: Mess would provide a larger surface area to decrease heat and allow better flow.
Plan on adding pump for a smaller design and better bubble release.

Electrolyzer Design Modifications: 

Using 1/4" plexi-glass to view the interior. 5/16" SS bolts for eletrical connections. 1/4" x 3" nylon hex nut (Ace Hardware) for carrier bolts. I prepped the plates with a Dremel and grinding bit to cross-hatch the plates.

Electrolyzer Problems: 

The 1/4" SS bolts didn't hold up to a higher amp pull. Over 26 amps. Tested higher amps to see what it would do. Melted the 1/4" acrylic.
Also my vehicle lost it's water pump. Which costs too much to repair and I purchased a new vehicle.
It'll be in the vehicle section.

Final Electrolyzer Notes: 

When prepping the plates use gloves the oil from your fingers really does stop the production of good stuff. Use a relay to operate your generator!!! Lowes sells Roebic, 100% NaOH.
Cleaned the plates with 5 amps for a week steady. Conditioned the plates @ 14 amps for 10 days. About 20 hours per day run-time.
MMW @ 6.07
I wrapped the exterior with electical tape and super-glued the ends, to keep it from unravelling. I tried super-gluing .093 acrylic plates to the sides, but they came off.
Hope this helps everyone!!

Cup O' Smack

I saw some video online of the twister HHO cell made with stainless steel cups, and decided to get some to play with. I took 16 of them and arranged them in the same pattern as the plates in the Smack Gen I, and created the Cup O' Smack. The cups are pretty cheap - I think I paid under $6 per dozen - so if they work it might be a way to lower the cost of a Smack. The wall covers are $1.69 each at my Home Depot.

Here are pictures of the cups I used, drilled to take a 5/16" rod, with 2 smaller holes for circulation:

Here are the cups being arranged on the nylon rod. The spacers I used to keep the cups close but not touching were cut from circular grids used in knitting (I guess - I found them in a craft store for $1 a dozen). They come in sheets as well, and I had picked up a bunch when I was trying to run some tests with stainless steel mesh.

Each pair of cups is then connected to the next pair using two stainless steel jam nuts (from McMaster - the same part as the original Smack).

After putting 4 pairs on, I then put on the other lead strap on. My straps are 6-7" stainless steel hose clamps from Lowes (about $1.50 each), with heat shrink tubing around them. They are thin, which is a minus, but they are flexible, which makes it easy to bend them to fit in around the cups.

Here is how the straps connect in the top cup. There is a long one going from the top to the bottom of the stack to act as the strap connecting the two outer plates in the Smack design.

And here is the completed stack, with all the straps wrapped and attached.

Testing
Electrolyzer Problems: 

I haven't run it long enough to really test it out, and haven't conditioned the plates yet. The amperage was increasing some, but I've only tested it in a fairly strong NaOH solution. I think I could add 1 more cup to each end like the Smack 1.5 design, to try to keep the heat down.

Final Electrolyzer Notes: 

More testing is needed, but it is a promising start, and much simpler than the twister design I've seen online.
