If the circuit does not work straight away try reversing the primary and feedback winding connections.

Since making this video I have learnt that a fast diode to protect the transistor is a MUST as back EMF can easily kill the transistor without it. The easy to find UF4007 is suitable for this.

Sorry the tutorial is not very good and I do not like speaking on camera.

  • Yo thanks it worked , i was trying the highr winding higher voltage but i was limited on power i am using two six volt lantern batteries were do u buy 12v in the u.s

  • @Jhfgsjdcd Ok. I am not sure if you can buy 12v lantern battery's but two 6v lantern in series is 12v which will work the same. I used a 12v lead acid battery for mine and I got it pretty cheaply at a local battery specialist shop. It might be worth asking at a local scrap yard as they will usually give you them for free or next to nothing.

    Also do upload a video of yours arcing at some point.

  • Yo i got the arc but i disconected connected and no arc

  • @Jhfgsjdcd Sounds like there is a poor connection somewhere. If you used enamelled magnet wire for the coils then I would advise you to use a sharp knife and scrape off any excess enamel you might have missed.

    Solder is the preferred way to make wire connections as it will not come loose.

  • Sorry using ipod i cant i tried it but still no outpuy

  • @Jhfgsjdcd Well when you get to a computer click the link as it is an instructable guide with all steps easily explained, plus there are some trouble shooting steps near the end of it.
