The transistors are NPN transistors.

hehe cool! How many pins on the bottom of that trigger coil? And how are they hooked up? Can you post a pic of that please? How much current do you pull on the receiving end?

Whats the distance? Can you run a second JT from the wireless receiver? How many receivers can pull from the transmitter?

Thank you

There are 4 pin on the trigger coil you can see in the picture the one that isnt being used.  One one led you can see that doesnt look like its being used is goin to the + rail. 

I have not tried a JT yet. (This circuit is not a JT it is similar....kind of)

Not sure how many or distance yet I have just started playing with this circuit.

My vid  shows what I was looking for in this circuit

Hello Slayer 

Your last vid was great.  There's real power there!!!  Very nice

OK this is the test I really wanted to do and I'm sorry it doesn't show you much!  I have hooked up my AV sniffer probe to another simple sec circuit and I can pull light off the second circuit without drawing any more voltage or ma on the first circuit!

How is the first circuit hooked up? I see what you are doing now, you have two sec circuits one you are powering. One is wireless. I just don't know how to power the first one can you take a pic please

The first one is powered by my power supply and the +- of the second one are hooked up the same as the first.  Most people use a phone charger that takes a 1.5 v battery and pumps it up to 5.5v.  I use my power supply because its adjustable.
