Welcome to S&T GeoTronics LLC.

In the 12 years we have been in business, we have never had to increase our prices. So we are very sorry that because of the current and constant supply chain issues, China chip shortages, increased shipping costs, combined with the unstopping inflation pressures, we are now forced to increase our prices across the board effective January 1, 2023.

S&T GeoTronics could simply NOT survive without our costs adjustments.

We were back on Kickstarter! (and will return soon, again, Hush...) We are very excited about our latest product and the tremendous success we had during our latest crowfunding campaign. It way exceeded our expectations. But you didn't miss anything, you can pre-order here: Open DSKY on BackerKit

We are even more humbled by the Smithsonian Air & Space magazine mention in the April/May 2019 issue on "The best films, events, books, websites, and souvenirs."

We spent 3 years researching, planning, designing, testing, tweaking before we introduced the World to our OPEN DSKY. This Apollo Guidance Computer (AGC) DiSplay KeYboard (DSKY) Replica is stunning and should please our new and old customers. Please visit www.opendsky.com for more info. We shipped to 246 customers already.

Our "Open Enigma Project" on Kickstarter was also very successfull! Thank You to all who backed us. We are very proud that we finished fulfilling all these orders on time and have sold ALL of the 100 Mark 4 Limited Edition. We then released our Improved Performance Mark 4. We just completed a batch of our fine wooden boxes so we should be able to ship any Full (boxed) Enigma within approximately 3 weeks. All other Enigma product ordered here should ship within a normal 7 days as we have everything else in stock. Please contact us for special requests. THANK YOU!
