Fahad Posted May 27, 2004 Report Share Posted May 27, 2004 HiI completed this projecthttp://www.electronics-lab.com/projects/science/016/index.htmlbut I feel hard to make high voltage transformer 1000v /6000vand one could help me and tell how I can construct this transformer with more detail .. ???Thankx Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 27, 2004 Report Share Posted May 27, 2004 Fahad,Don't wind the transformer windings with your hand, or the wire will get twisted. Just spin the ferrite like a winch, and let the roll of wire also spin. Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted June 13, 2004 Report Share Posted June 13, 2004 Usually a varible speed Drill running real slow works well if you mount it in a vice. Run a screw and nut thru the core and put it in the drill. A Lathe works even better. Quote Link to comment Share on other sites More sharing options...

attackbat Posted June 24, 2005 Report Share Posted June 24, 2005 Any way to modify this or build one that will only discharge when the prongs touch the target without continuously sparking? Quote Link to comment Share on other sites More sharing options...
ante Posted June 24, 2005 Report Share Posted June 24, 2005 Hi attackbat,Welcome to our forum.You have to increase the distance between the electrodes, that’s all! Quote Link to comment Share on other sites More sharing options...
rfranzk Posted July 11, 2005 Report Share Posted July 11, 2005 I have completed this project and found nice output transformers at amazing1.com. I used the secondary of the output transformer for some nice kv voltage. This circuit will also drive an automotive ignition coil for approximately 40kv at this time using 8 AA batteries for power supply. Quote Link to comment Share on other sites More sharing options...

Serhiy Posted July 31, 2005 Report Share Posted July 31, 2005 HICan anybody tell me how to make T1 in this schematic diagram because I can not get it anywhere?http://www.electronics-lab.com/projects/science/016/index.html Quote Link to comment Share on other sites More sharing options...
steven Posted July 31, 2005 Report Share Posted July 31, 2005 :)dont worry about t1 if you biulfing this stun gun there are alternatives like a flyback driver circuit that not only powers flyback transormers but any transformer in reverse mode this will give you some good arcs to look at the topic hand powerd generator i used 2x 6kv ceramics to make a mini marx generator and this alone would be an ideal adition as it put out fat arcs when powerd up from the hand powerd generater Quote Link to comment Share on other sites More sharing options...

nacromonger Posted October 31, 2005 Report Share Posted October 31, 2005 hi there anychance of some help i have built on bread board the circuit ,have got about 650v across pins but have trouble with pulse transformer.imade one as per instructions but does'nt work .6ohms across primary winding+102ohms acrosssecondary,any ideas give us a bell.I have completed this project and found nice output transformers at amazing1.com.

Labtyd2 Posted February 2, 2006 Report Share Posted February 2, 2006 I have no idea what any of this is. I don't know much about electronics or anything. Is there any way of findind this in english? As in something I can understand? Quote Link to comment Share on other sites More sharing options...
MP Posted February 3, 2006 Report Share Posted February 3, 2006 Everything here is in plain English. This is a site for electronics enthusiasts. What are you having a problem to understand?MP Quote Link to comment Share on other sites More sharing options...
Labtyd2 Posted February 3, 2006 Report Share Posted February 3, 2006 Just about everything. I'm not all that into this kind of stuff. I'm trying to learn but I wouldn't know where to go to learn all this. Basically just wanted to try making this. Quote Link to comment Share on other sites More sharing options...
MP Posted February 3, 2006 Report Share Posted February 3, 2006 There are lots of articles in the "Articles" section which will help explain things. Our high voltage guru here on the site is steven. If you have a question about how the high voltage part of this project works, you can send him a personal message to user name steven and he will receive it. If it is electronics in general that you need help with, I recommend the articles section. There are also several eBooks posted in the Electronic Resources forum. Lots of beginner books and tutorials there.Hope this helps.MP Quote Link to comment Share on other sites More sharing options...
steven Posted February 4, 2006 Report Share Posted February 4, 2006 ;)thankyou mp im flatterd, even though i collect circuits for a hobby and biuld high voltage stuff , im not much for technicle exsplanation,s but it aint to hard to use a high voltage produceing circuit for things like a stun gun , audio guru is good at the technicle side of circuits , i just biuld them and upgrade and modify them and include new ideas into them Quote Link to comment Share on other sites More sharing options...
MP Posted February 4, 2006 Report Share Posted February 4, 2006 labtyd2, there is my point exactly. Just jump in like steven and you will learn these things by doing. ;)The circuit you are asking about is found here:http://www.electronics-lab.com/projects/science/016/index.htmlThe technical side: The basis of this circuit is a 9 volt battery used to power a 555 timer which is used as a charge pump to make an AC voltage from the 9 VDC. The 555 triggers the mosfet, which causes a pulse at the primary side of a 1:100 transformer. This ratio increases the AC voltage considerably (100 times at this step). The result is a high voltage at the end of this circuit, which is labeled as a spark gap. This is the point where it is very dangerous. The spark jumping across this gap is HIGH VOLTAGE.There was a conversation about this project here: http://www.electronics-lab.com/forum/index.php?board=2;action=display;threadid=835I taught my son how to make a similar device which was used for an arcing visual effect. This one was simply a 555 charge pump amplified with a 2N3055 and fed to an automotive coil. It was for a project when he was in the 9th grade (several years ago). I got a call before day's end to come pick up the battery pack. As soon as his teacher saw his demonstration to the class, she confiscated the battery pack for safety. However, she did give him an A. ;DMP Quote Link to comment Share on other sites More sharing options...
master-m Posted February 19, 2006 Report Share Posted February 19, 2006 Hi all, i need help here..i couldn't find IN4007.. any diode can be replaced? thx in advance Quote Link to comment Share on other sites More sharing options...
steven Posted February 19, 2006 Report Share Posted February 19, 2006 :) a uf4007 high speed diode will do to, i even use them to . Quote Link to comment Share on other sites More sharing options...
MP Posted February 19, 2006 Report Share Posted February 19, 2006 Others such as BY133 and P513 can also be used. 1N4007 is rated for 1000 volts / 1 Amp. If you substitute, you should use the same or better.MP Quote Link to comment Share on other sites More sharing options...
