Creat your own spark?( were do the capacitors go)

[Trent]

There are 3 difrent capacitors but on the scematick and in the text thre is only one mentoind can anayone help me?

The schematic is correct. This has come up several times on this forum and been answered by numerous experts. It is always a good idea to do a search and see if the question has been answered. I suggest you read the instructions carefully, again:

In this project there are a number of variables you could choose to investigate, for example:
the number of turns on the secondary coil,
the value of the bypass capacitor,
the width of the gap between the high-voltage spark contacts,
the shape of the high-voltage spark contacts,
the voltage on the primary coil (6 vs. 12 volts).

Materials and Equipment
1.0 μF 250 V metal film capacitor (e.g., Radio Shack part number 272-1055);
0.01 μF 50 V capacitor (e.g., Radio Shack part number 272-1065);
0.1 μF 250 V ceramic capacitor (e.g., Radio Shack part number 272-1053);

Variations

What happens if you change the value of the capacitor connected across the contacts of the interrupter?
If you are very curious you can enclose the spark gap in a transparent, sealable container. You can then investigate the dielectric breakdown voltage for different, noncombustible gases. Air, nitrogen, carbon dioxide, and helium are such gases. Do background research to find out the dielectric breakdown voltage of each gas you intend to test. Will the maximal spark gap distance increase or decrease compared to air? Do an experiment to confirm your hypothesis.

Using the bare (uninsulated) 12 AWG copper wire in the material list for the primary is wrong. When it is wound on a metal bolt, it WILL short circuit the coil making for a poor electro magnet and a poor electro magnetic field for a transformer. Type TWHN solid 12 AWG copper wire or similar should be called for.

The relay is shown incorrectly. The normally closed contacts should be oriented away from the bolt head so that when current flows, the primary and bolt act like an electro magnet and open the contact. The normally closed contacts should be wired as shown, it is just the mechanical orientation that is wrong.

The description of the building of the apparatus should indicate that the Neef vibrator should be constructed and tested and be in good working order BEFORE winding the secondary! This should be done to allow working with the circuit without the high voltage danger!
