the Adventures of T.E.C.

the continuing Adventures of Sara Cladlow

Hi, I’m Sara Cladlow. For the past 6 years I’ve been a social consultant in the Washington, DC area. I have met some truly unique people along the way and they have opened so many doors for me. But now it's time for something completely different.

I am teaming up with Tod Troche and Lory Ester to form T.E.C.!

Together, we take on challenges across the globe. If something (or someone) important is lost or stolen and traditional solutions won’t work, that is where you will find us.

My adventures are chronicled in the eChallenge puzzles.

You can read my adventures and test your skills by solving each eChallenge puzzle.

More About eChallenge Puzzles

The eChallengeCoin is an electronic coin with puzzles to solve. There will be an annual eChallengeCoin.

The 2020 thru 2023 eChallengeCoins have a series of interactive challenges which use a combination of touch sensors (or buttons) and LEDs. When appropriate, an puzzle may have additional interactive elements such as environmental sensors or sound. In addition to the interactive challenges, each new eChallengeCoin has another story from the Adventures of Sara Cladlow. Within each story, you are tasked with solving the challenges Sara encounters. The story is accessed through the serial connection on the eChallengeCoin.

Starting with the 2024 eChallengeCoin, the challenges have been replaced with all new text adventure games.
