Welcome to our new website! We are proud of our new look, and we are eager to provide you with an awesome experience: whether you're building our kits or buying unique historic replicas with a modern twist. Thank you for your business!
We are Your Worldwide Open Source solution for fine Replicas.
Makers of the World-famous Open Enigma and Open DSKY!
S&T GeoTronics makes quality Open Source retro tech replicas. It's what we do: combining our passions for history, technology, and engineering to bring you these unique products. We believe in craftsmanship, being intimately involved with the making of a piece of art that is well-made, long-lasting, and desirable.
An identifying factor of our craftsmanship is our interest in the process of creating. The focus is on the product, the creative process, and how much enjoyment it brings. We are dedicated to Open Source, and you can make what we make by following our instructions.
These machines are assembled entirely by hand, by us, in our very small workshop. We have no "mass production" equipment. Each wooden case is made from 3/8" selected imported wood, and fitted with the best materials we can obtain. These cases will last as long as the electronics they contain. We look forward to doing business with you.

We are dedicated in providing you Open Source products and we invite the community to comment and collaborate.
We take pride in everything we do: From recreating historical devices to providing vintage technology for the modern era.
We are Makers at heart and we provide kits for all our products, or we offer fully assembled and tested units.
We take the time to assemble our units one by one in the sequence they are sold.
Arduino is aplatform we love and is at the center of both our Open Enigma and Open DSKY.
