The Colorado Springs Magnifying Transmitter Scale Model Design Sheet is here!

This selection of downloadable PDF designs offers the opportunity to build what is quite possibly the world’s most advanced Tesla coil. Designed by Nikola Tesla, scaled down to the finest detail, this coil is the real deal.

Also available: Custom designs

Looking for a specific frequency? Custom designs are available for any frequency between 200 kc and 5000 kc (200kHz-5MHz) so you can build a small desktop model, or a 3 metre giant that will take over the garage!

Now is your chance to build your very own scaled down fully-functional Tesla Magnifying Transmitter!

Another great introduction into Nikola Tesla’s work is Eric Dollard’s Crystal Radio Initiative

The Crystal Radio initiative is directly related to the Magnifying Transmitter and is recommended to anyone who would like to learn and follow in Tesla’s footsteps.

The Crystal Radio Initiative is your gateway into Nikola Tesla’s world.

It’s not magic.

Just good old radio principles.

“The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter – for the future. His duty is to lay the foundation for those who are to come, and point the way.” – Nikola Tesla
