How does someone get access to the HHO forum? It seems password protected but the registered password isn't working. -Opa Sorry, Its just for Me. Gary

If you look at the Picture of the Assembled detector, It IS a SCRAMBLE WOUND Coil. I would recommend you make it that way. If you LAYER Wind your coil, It will have a Higher Inductance, and MAY Not Work as good. Gary

Sorry, No Comment as I haven't seen that kit or schematic of it.

Hello, I need to wind about 163 (120+43) turns of 0.3mm copper wire around a short 4.9 cm ferrite rod (it's for a small metal detector) I suspect that there will be too many turns in the coil to wind it in one layer, so I'll presume that I'll have to wind it in layers. But I was wondering how this should be done precisely; as I understand it, the windings should be in one direction, but I guess it is "not done" to start winding a coil, say, from left to right, and then, at a certain point, continue winding from right to left. Is the solution to this problem that I should begin winding a first layer (for example from left to right) and at a certain point return to the beginning of the rod and start winding a second layer, also from left to right? In other words, say I have to wind a coil of 30 windings, but I only have room for 10 on the rod, and have to wind 3 layers of 10 windings each, does winding nr. 11 have to be above winding nr. 1 and winding nr. 21 above winding nr. 11? I thank you in advance for your help. Reply With Quote IF its the transistor "Pinpointing" Metal detector that I have seen on the internet, you can "Scramble wind" the wire. (Just wind it in a Bundle, not neat layers.) Also, it doesn't matter of you wind both coils in the Same Direction. What matters is that if it doesn't work when you wire it to the circuit, Just Reverse the wire connections on One Coil and it will correct it. PS: The Circuit works OK, as claimed, but I'm not very impressed. I can Pinpoint just as good with my PI Detectors using an 8 inch coil and with much greater distance of detection. Gary

zlron Please do use a Bubbler with HHO usage. I have always run a bubbler on my Hydroxy units and never had any safety issues.....except when ...................... I had forgot to check my wifes unit for a time { the bubbler had used some of its liquid - it had gone too low, allowing free passage of gasses}. She was reversing her cold vehicle at the shopping centre. It backfired...and Boooom. Missus describes it as the Loudest CRACK sound she had heard. On investigation - the Bubbler had exploded- luckily it was the weakest link. ----------------------------------- do try putting a vacuum on the out put pipe from a bubbler. I think you will find that it does draw from the Hydroxy supply pipe. It may not transfer the full vacuum of motor to the Cell , but it certainly will increase the output. Glenn. Maybe its time to put a water level detector on the Bubbler?

But Before Coating it with anything, Make sure ALL Solder Flux is REMOVED, on Both Sides of the Board. Tinning the copper doesn't help much, as tin can also react with salt over time.

What file? maybe just one of the packages? So you will be able to unselect this package and go on. Lamazoid and others: One person in my town, Downloaded that program for me and made me a GOOD WORKING CD. Unfortunately now I find out my present computer doesn't have enough memory to run it. (Only 64 Mb Ram.) However, I have another computer here with enough memory and trying it to run "just from the CD" It does run.(But I now know for sure, that previous CD had a problem.) So When I get some time, I will do a Full Install and see if it fulfills my needs. However, TODAY I have to go for a CT Scan, as One of the Xrays they took when trying to solve my arm problem Showed a Spot on my Right Lung. So Now I have to find out if this is Cancer. If it Isn't one Problem, IT ANOTHER!

I Also Checked the Content of the Disk in Dos. (Dir/s) It does NOT Match what the website claims for Number of Mb. One guy in Town here, Say he will see about downloading it for me and put it on a CD.

Thanks Gary, that would work for what I need. How's this, A Photograph, Using my Camera.

hmm i have this version, but i've tried only live cd. Anyway it should work "out of the box" in most cases... what is the exact problem with your installation process? Also, what are your PC specs ? And also, did you perfrom total re-partitioning and formating in native FS during install, or not? Yes the Harddrive was Partitioned and Formatted Correctly. I have done this stuff MANY TIMES. I Love DOS. The Ubuntu CD I got Has a definate Error. Installing it Inside windows, "It Goes so far, than says it can't find a Particular file. Installing it to run Outside Windows, It installs to a point, than just Hangs. (Sorry, I Can't remember Exact file name that it said)

Gary, what version of Ubuntu? The Latest Version. (8.04)

No, I Can't Create a PDF.
But I could create a Picture File (JPG or PNG or GIF) of "Just the Schematic", and in a Reasonable Size.
Is that what you want?

Hi there.. About the Heating post. i have build the same unit, etched a board put it together,the schematic says lm555 i checked a dataspec and the NE555 is the same ic. I made about 3 coils one from 16 gauge about 10 loops diameter is about 20 cm did change the cap to 100k still the same problem.tried 15 loops same diameter with coms cable ( piece of cat 5 ) and ;( ...150 ohms getting hot and LED not turning off.. Any ideas ? Thanks Jared Any 555 is OK. The "LM" is made by National Semi, the "NE" is made by Signetics. If the LED is Not Turning OFF, You do Not have it set correctly to achive a Resonance and in that case, the resistor may get hot. In My Write-up, It says a 3 to 6 Turn Coil, 4 to 6 FEET Diameter or Square. 1) 16 AWG wire is a Bit Big. I would suggest a 20 to 22 AWG. 2) Your 20 Cm is TOO SMALL of a Diameter, But May work with around 12 Turns. 3) The 150 Ohm Resistor Could be increased to a 220 or 330 Ohm to reduce current flow, IF Required. *** I'll Try a Prototype Later Today and Post My Results using an 8 Inch (20Cm Coil.). UPDATE:Winding an 8 inch (20cm) Coil with 12 Turns of 22 AWG Enamel MAGNET wire, (Scramble wound and Taped to make a Rigid Coil) and using a .22uF cap Works Fine. With the 150 Ohm Resistor, Total Circuit Current draw is 90 mA. NOTE, I have No Resistor Heating Problem. (However, My 150 Ohm resistor is a 1/2 watt resistor in a 1/4 Watt Package.) ALSO, Recently I bought some 2 watt resistors, manufactured by "BC COMPONENT". The Operating Temperature of these resistors at 2 watts is OVER 300 Degrees. WHAT CRAP is that! DO NOT BUY ANY "BC COMPONENT" RESISTORS, If you can Avoid them. Changing the 150 Ohm Resistor to a 330 Ohm Resistor, Total Circuit Current Draw is 60 mA. But I find a slight Reduction in Sensitivity. ** IF you Use wire with a Vinal Insulation, it will have a LOWER Inductance, for the Same number of turns. *** I ONLY Recommend Enamel Wire. (The type used in winding Transformers.)

Probably a linux flavor like Ubuntu which I use. Free, works great and free support if ya get on a IRC. Once ya get over the learning curve, you won't go back. Plus it will work on older pc's. Problem is majority of slopware is written for MS Windoze systems, but there are tons of very good free Linux software and it has become so much easier to use and install/de-install now. Yes, he sent me that Ubuntu system. Yesterday I tried to Install it Without Installing win98, But it wouldn't work at all. Next I Installed win98 than tried to install the Ubuntu, to Run Outside of windows. Also Wouldn't work. So today I will try to install it INSIDE Windows. Furthermore, after many tests and Xrays, I Never did find out Why my arm was hurting, and now it seems to be getting better on its own. However in the results yesterday, one of the Xrays shows a "Spot on my right Lung". So now I have to go for a CT Scan.

Richard, No I wasn't planning to modify the existing PCB, just going to use the timing circuit. No sense in reinventing when the circuit is laying here. I will just jumper to another PCB that will carry the high voltage components. Sounds like a plan to me. I just couldn't see the plan clear enough. rmeyn I Downloaded the Latest version of Adobe reader (Ver.9) on this computer and it was almost useless. (33.6 Mb of CRAP) So I put that PDF on my older computer and using Adobe 6 running in a CD, I was able to select amd print Just the schematic portion, Clear as a Bell on 8.5 x 11, and Full Size of the page. Sometimes, Older is Better.
