Hakasays presents Build a Better Tesla Coil, an engineering crash course into Tesla’s coils, how they differ from modern Tesla coils, and how they can be improved and built more efficiently.
His presentation explores why many modern Tesla coils look different from what Tesla actually built over a century ago. He emphasizes that many of the coils his group works with use only one extra coil, with no primary and no secondary, while still achieving strong effects with little to no power.
The session includes lessons learned, practical tips, and demonstrations comparing simple, efficient coils with conventional Tesla coil setups. His work follows Tesla’s original research while drawing on insights from experimenters such as Eric Dollard and Griffin Brock.
