    Schematics Variable current 12v 60A to 0A

    Ante, it sounds as though you could use this device more than me at the moment. What model vehicle do you drive ante, I can keep this in mind as I developed this system. There are similar emissions control in other states here in Australia, but not in Queensland yet. There seems to be Swedes...

    Schematics Variable current 12v 60A to 0A

    Yes vehicles have gone pretty much the same way here. I don't really see all that much of a problem, in using a fuel injected engine. new carburettors are easily obtained through high-performance shops, or even wrecking yards. You would have to modify the electrical system for the fuel...

    Schematics Variable current 12v 60A to 0A

    Have you had a look at this yet Ante(http://www.hasslberger.com/tecno/hydrogen.html) this has made me vary from my design a little. Unfortunately there's no way I can add extra electrodes. Do you think the circuit in your notebook, could be modified to accept multiple MOSFETs. It would be nice...

    First Project

    Yes kasamiko suggestion for a first project is a good idea. If you're feeling a little more adventurous, this was one of my first project(http://www.electronics-lab.com/projects/power/032/index.html) it is fairly simple and gives a lot of information on how it works and how to construct it...

    Schematics Variable current 12v 60A to 0A

    How does the bypass relay work Ante. Does it bypass the MOSFETs, to allow direct current to the load. Can this be controlled to stop it going above a set amount of current. If it could be capped that would probably be OK, although I am not sure where I would need it to cut in, I think it...

    Schematics Variable current 12v 60A to 0A

    Yes Ante I think a shutdown sensor will do the job. No I don't have an oscilloscope, that is a little bit to technical for me at this stage. The mosfet that I'm using is (MTP3055E). I don't have any way of measuring the heat so I guess I might add a bigger heat sink, and let it run at fall...

    Schematics Variable current 12v 60A to 0A

    Yes that coffee additive does the job Ante 8). I feel I'm over the worst of the flu now. I had to do some rethinking of my overall design after finding this ( http://www.hasslberger.com/tecno/hydrogen.html) I have heard of this inventor, and try to find information on his invention many times...

    Schematics Variable current 12v 60A to 0A

    Sorry Ante I gave you the wrong Web address ::), this is the one I was referring to (http://www.armory.com/~rstevew/Public/Motors/H-Bridges/Blanchard/nch-brdg.htm) I've been battling the flu for the last few days, I'm not really with it :P. I'm glad you're wanting more information, I was...

    Schematics Variable current 12v 60A to 0A

    The on-off point. When I reduce the power to the minimum I still had power to the electrodes. This was something like less then one volt. I was thinking a transistor at the base of the MOSFETs and a trim port at the base of the transistor. So when I increase the power to the electrodes as...

    Schematics Variable current 12v 60A to 0A

    Thanks again for your reply Ante. I built the first circuit the one with the multiple MOSFETs. It worked very well with a single MOSFETs and a small load. I'll add another MOSFETs and test it to its maximum in the next couple of days. The MOSFETs that was available to me that seem to suit...

    Frequency generator to shut off street lights.

    I may have a solution. the scientific name for it is (throwrocksrunfast) ;D. Maybe a camera flash, if you could in case the flash unit in mirrors to direct it to the focus lens, as is used for the laser. Of course you would need to make it flash rapidly, or use multiple flash units and make...

    HELP!!! im new hir!!1

    I have attached the ICL 7106 LCD datasheet, it also has the ICL 7107 LED. I hope the attachment works. There is also a project on electronic lad (shttp://www.electronics-lab.com/projects/test/007/index.html) for an LED voltmeter using this IC...

    Schematics Variable current 12v 60A to 0A

    Thanks for sharing your knowledge with me Ante. You have help me fill in some gaps in my understanding of these things. I have found quite a few PWM projects on the net, and have spent some time trying to understand how they work, I seem to be getting a grasp on it. I found two projects that...

    Schematics Variable current 12v 60A to 0A

    I didn't know what PWM was. so I done a google search,for the applications it is being used for it seems like the way to go. Do you know of good schematics for my application. So basically it turns the power on and off the faster the switching the more current it provides?. What happens when...

    Schematics Variable current 12v 60A to 0A

    Thanks for your reply Ante. My idea of using existing battery for start-up. When the ignition is switched to the on position, it will connect to the storage device to charge it as well as disengage the relay to the starter motor. And when the unit is fully charged disconnect and reconnect the...

    Schematics Variable current 12v 60A to 0A

    I need a circuit that will allow me to continuously very the output current with a potentiometer. I needed it to be able to. Limit the maximum current. Be very reliable. Run continuously at maximum current. The current value must be in the same position on the potentiometer when continuously...

    Television safety (help)

    Thanks tel1958 that would be great. (Printed on sticker on the back of TV) Sharp Corporation of Australia. Model NO.CX 48D3 Serial NO.08744 power supply 230-240~50 Hz,80w I am unsure of what numbers on the circuit board is too identify it. So I will tell you what I can see. On a...

    Playing with hydrogen

    Thinks harsh. That is the kind of information I am looking for. I don't think using electrolysis alone or with commonly used chemicals such as salt and sulphuric acid, Is going to produce the amount of hydrogen needed to run a car or generator. I think finding a chemical that isn't as...

    Playing with hydrogen

    I am looking for methods of producing hydrogen from water. If anyone knows of any good sites please let me know. And also does anyone know of the best material to use for the electrodes that doesn't deteriorate. I have done some experiments with sulphuric acid dial looted with water and water...
