Mindscrape, I'm so thankful for your attempts to help, anyway, I solved this problem already, and if you are interested I would upload the solution here. La, Lp, and Lr are some kind of transformers as you said, their primary and secondary windings are one above the other with a thin insulator...

Well, I have enough time to complete this project. Actually, I should send the request until March. I asked my friend for help, he is an expert in electronics, so he is going to send me the board and all the needed components, however, there is an electronics store in range of 50km. The movement...

I solved it, thanks for your cooperation

This is primary school competition, so it was very easy to win until this year. My friend is the best opposition, his project is Tesla coil. We are learning the basics of the electricity, but my friend went too far. I think that I am going to build some kind of a movement detector so it count...

[SOLVED] pls HELP me There is an electronics competition, so can somebody tell me if there is something better than Tesla coil. The opposition is going to have a demonstration with a Tesla coil. What is your suggestion? What should I construct against the Tesla coil?

I should make a project for this year electronics competition. The opposition's project is a Tesla coil. help

[SOLVED] Something better... Can somebody tell me if there is some kind of better project than Tesla coil. I really need your help.

what's the ratio of the transformers?

The transistors aren't problem because I can buy some from the electronics store ( I already asked if they have some, they cost not even a dollar). Getting the carbon mic is not a problem too. The only problems are those coils I marked above and the 100pf high voltage capacitor, 'ALfa...

[SOLVED] Spark transmitter 1. Hello, I am making this project ( a spark transmitter and a receiver), my problem are those coils below ( Lp, La, Lr). How are they connected to the circuit. three images are attached for the detail please help me thanks
