Fusor Forums

Charlie, I like your website's layout and I think it can be helpful in communicating about your project. To be frank, a prospective donor's biggest question is typically "What's in it for me ?" Family and friends have a personal interest in your career and academic successes, but the wider world pro...

Chris, My goodness, you do have a short-term memory problem today. The reason your power supply is being discussed in this NST thread is evidently because you brought it up . Now there would be nothing wrong with bringing it up as an alternative, but the reason we're in this donnybrook is because of...

Good grief. "NST": A true transformer operating at 50/60 Hz, referenced in various FAQs and many demo projects. "Neon power supply," as linked in the original post in this thread: an off-line-powered high-frequency inverter with a balanced, center-grounded output, made specifically for driving neon ...

That is a real NST. Good luck!

Okay Chris, show me where someone powered a fusor with a neon inverter. Sometimes things get past me, but at last count, the number of successes was zero point zero. I'm sure it's not for lack of familiarity that these are poorly regarded in our community and the Tesla coiling community and the HV h...

There are no "detailed instructions", "step by step info", or schematics. What we have here are the archived discussions about hundreds of successful, highly-indivualized, fusion projects spanning the last fifteen years. You're strongly encouraged to get familiar with these projects on your own init...

This is not a transformer. It's a high-frequency inverter-based "neon power supply". Your clues are the weight, the shape, and the absence of ceramic insulators for the output. Unfortunately, these supplies are of no known utility in the fusion hobby. You need to locate a real transformer. They are ...

No neon sign transformer outputs DC. Not all neon power supplies are transformers (NSTs) any more, but all are AC power supplies. DC ruins neon tubes.

The standard tried-and-true spherical chamber recipe is two decorative 304SS hemispherical shells from an architectural ornament company (JG Braun, Wagner, or possibly others), which are then TIG welded into appropriately-sized standard bored CF flanges. The hemispheres can have ports milled out to ...

All of these are standard neon sign transformers (NSTs). All are suitable for demo fusor power supplies. The use of NSTs is covered thoroughly in the FAQs and archived discussions. Suitable vacuum pumps regularly show up on eBay for under $100. Search local sources like Craigslist or lab auctions to...
