Very nice HHO gas tester from Sidyoung

Have a look at this brilliant design to
test the HHO gas output !

Well done Sid !

Wow... that's a very nice advancement of Zero Fossil's design, Sid. Well done!

It got me started building one too.  Picture 1 shows my finished unit.

When I got to the part where I set it on the wood platform, I was not sure if you put screws through the bottlecap supports and somehow waterproofed them or what. I wanted mine to be stable but knew with my luck, I'd be doing good to leak proof even one connection through the reservoir bottle. I decided to make an external support and give Murphy fewer shots at me.

I had some stiff wire of some kind. Someone had dumped a spool of electrical wire in the woods by my house (Thanks!). It had 3 insulated 16 gauge copper strands and one insulated conductor of some kind of steel I guess. It is about 10 gauge and a magnet sticks to it. It was covered with black insulation so I guess it was meant to be a support wire and ground wire, although I expected aluminum. Anyway, it was very stiff and springy, but I finally got it bent into a circle of the right size and welded it to itself. Then I just used 1/8" steel welding rods for the legs which I brass brazed. Then I brazed on 4 fender washers for mounting tabs. A shot of black spray paint on the legs and washers and you have picture #2.

I used a small brass 90 degree plumbing part I found in the junkbox to go through the bottle bottom. I found a plastic straw but it was a hair too large to fit into the brass part. I heated the brass up just enough to soften the plastic of the straw and then teased it into the hole. A touch of super glue and it seemed solid.

I've found a use for CD-R coasters! Chuck up a hole saw in the drill press, put the cd on a block of wood and make plastic washers! I used high speed and it leaves a little melted plastic around the edges that I have to sand off. Then I made a couple of rubber washers the same way from a piece of bicycle inner tube (careful, if the saw grabs the rubber it can wrap it up and whip it around for more excitement than you cared for!) . I superglued the rubber washers onto the plastic washers and used them to seal the thru the bottom connection. Tested it with water and.... Murphy got me.  It dripped.  So I slapped some 4 minute JB Coldweld steel epoxy on the washers and reassembled it and it didn't dare leak. Picture 3. The little red hose connector is another innovation. It is the plastic insulator off an electrical spade connector. I ran a 7/16" drill bit through it to open it up a little more. It just fits the hose I'm using. I used epoxy to secure it in the brass fitting.

Picture 4 is just an inside the bottle shot.

I'm just using a 500ml water bottle so far. I don't have a cell made that produces enough for me to install a larger gas recepticle, but it will be easy enough when I want one. The 500ml bottle tilts when it gets to the top but does not fall over, so it is a hands free operation.

This is just a variation, another way to do it without a lot of holes in the bottom of the reservoir to mount it.. Thanks Sid for the push in this direction, and my hat is off to you, Zero Fossil, for the top notch experimentation and documentation you have been doing!

This is just a miniature version of an old fashioned gasometer. They have been around since Victorian times. When I was a kid every town had them in the local gasworks. It is amusing to see how those old ideas get re-invented every now and then. :-)

See http://en.wikipedia.org/wiki/Gasometer  for the industrial version
