RE: [TCML] breakouts and a picture

["Lau, Gary" <Gary.Lau@xxxxxx>]

Hi Simon,

The TCML does not permit attachments, so we didn't see the picture.

The first question that must be answered in troubleshooting a coil is, is the primary in tune with the secondary?  In your video, I didn't hear any mention of tuning.  Have you tried tapping the primary differently and determined if it improves or degrades performance?  Did you use some type of design software to choose the components?

And there's any number of other issues that we can't deduce from your video.  Details of the spark gap, and capacitor type.

When you do get your coil running well, you probably shouldn't try holding the metal rod in your hand and drawing sparks to it, unless the rod is securely wired to a good ground.  You don't want that current flowing through your body!
