JACOB'S FORKS?

Step 7 LIGHT SHOW

The electricity arcs back and forth between the tongs of the forks. You could use any number of metal objects to achieve different effects. Just remember to be careful.

Does the monitor still function? Could it be put back together and used as a pc monitor still with the forks lit? That would be a sick pc mod

Not back and fourth. That will only happen if the TV is ancient. If it's newer than 1985-1990 it will be DC. One way

I think he means it sparks between two random close tongs, but keeps switching between them. For example, numbered counter clockwise, like a chip, there might be a spark between tongs 1 and 8 for an instant then maybe 3 and 6 next and so on in a random pattern.

So, I've got a sack of high voltage transformers salvaged from CRTs, but the low voltage side has a ton of pins (10-15). Do these transformers normally use 12vdc? 120vac? Will Bad Stuff (TM) happen if I run them at the wrong voltage? These were all free so I think I will just experiment.

This instructable showed a way to power a flyback transformer: http://www.instructables.com/id/MAKE-A-HIGH-VOLTAGE-SUPPLY-IN-5-MINUTES/ I haven't tried it but it looks like it will work. It also shows how to determine the correct pins to power.

I've done this a couple o times. I get at least a 1 inch spark for about 2 seconds. Then a relay cuts the monitor off. I've considered bypassing the relay, but I don't want to overload the circuit and lose the driver. And I've tried putting 10w resistors, (2k) on our main line from the flyback. That weajend the arc, but it still cut off. What do guys think is the best solution to this problem?

interesting read! Thank you for taking the time to post this... and yes, we enjoyed the red carpet ;)

awesome, i thought you might like to know that we tried it to and it looked great.... until the monitor died :-) thanks anyway!

Jacobfork, have you ever seen a 'trick' using a paper towel tube, two pieces of aluminum foil, a 9v battery and some type of RC circuit, that will cause an increasing, building shock if the two pieces of aluminum are connected between the hands?

Wow!! what are you trying to do,you should of stuck with the two copper rods,you shouldnt carry the force back to the monitor,lucky you have the contacts insulated on both sides,there is roughly between 30 and 40kvs travelling through those contacts,this picture does not show a jacobs ladder,and you should of insualted the jacobs ladder too, for safety.

The project is about "Jacob's Forks," not a jacob's ladder! Anyway, nice project!
