  • High Voltage Power Supply For Marx Generator

    Hello, I built this power supply for my marx generator, but it only sparked every thirty seconds. On adding another stage {two capacitors} it sparked every twenty or so seconds, over a spark gap of a couple of millimeters. I then added two capacitors rated for 4KV, and it sparked every twenty seconds, with much brighter sparks. I connected it to my marx generator and my marx generator sparked every four or five seconds over a maximum spark gap of about half a centimeter to one centimeter. The voltage is onvuiously not enough. Could someone please tell me how to make this multiplier spark more frequently? Thank you.

    Build a simple Marx Generator

    Hello PLasmana, thank you for the instructable! My Marx generator is pictured below. I built your power supply, but it sparked only every thirty seconds, so I was forced to find another power source for the generator. The mosquito bat pictured outputs about 2.5 kilovolts.. Also, I bought variable resistors by mistake instead of the normal ones. They work fine, though.

  • Also, an ideal method for detecting pranks about hydrogen as a fuel would be to see whether they call it brown`s gas or HHO. Please be careful.

  • I also found this- http://www.ebay.com/itm/220v-12V-1-5W-output-Voltage-Isolation-Dry-Type-Transformer-Toroidal-Tube-/201379530624?hash=item2ee327c780:g:O8oAAOSwMmBVkP4s

    Hello, could I use a current transformer like this one-http://www.ebay.com/itm/OMRON-E54-CT1-CURRENT-TRAN...According to wikipedia, these transformers consist of a single ring as a core, and wire wrapped around it is the secondary. A copper bar is the primary. Could I try powering such a transformer backwards? From what I can see, the core appears to be quite large, and can sustain a large magnetic field.Please forgive my obvious naivete. Thank you.

  • Thank you again, downunder35m. Your comments have been very helpful. There are some stores in my area which contain old and unused appliances, metal, etc. I will check there. As for the cable, I believe I already have some that might work. I will have to, of course, confirm that based on the core I manage to obtain.

  • Firstly, I would like to thank you all for commenting.bravoechonovember1- 180 dollars is 11970 rupees. Which is way beyond my budget. Besides, I believe I will learn a lot building one.Downunder35m- For me, waiting for the transformer to cool down is really not an issue. I don`t want to weld anything fancy, just very thin sheet metal. However, if even a MOT won`t work, I will look up isolation transformers. I suppose mine would just overheat too quickly to do anything useful.Yonatan24-Thanks for the link! The transformers on there are definitely cheaper than what I have seen. I will attempt to select one from there.
