are making these DIY, Open Source Induction Heaters
available to you, for free.
Our aim is to advance the exposure of induction heating to as many people as possible. We encourage you to experiment and submit ideas for design changes to further improve the designs.
Roy 1200 is our main open-source project, and for the more
advanced enthusiast, we also offer The Maggie.
The Roy 1200 analog induction heater is one of our analog designs. It is based on the Royer Oscillator, with many design advances that enhance reliability and power of this classic circuit. While nowhere near the reliability and feature set of the Roy 1500 digital induction heater, the Roy 1200 offers a great starting point for budding enthusiasts and those who are bound by budget.
