Technical Machine seeks to empower software developers to make the next generation of physical, Internet-enabled devices from prototype to manufacturing. Its Tessel Its flagship product, Tessel, is more than a programmable microcontroller; it's scalable and iterable. The base Tessel board and its simple, plug-and-play sensing and actuation modules are designed to be easy to prototype and iterate on an early-stage idea. It's even easier to update the code after the product has been deployed, and to use the modules to better understand how Tessel-enabled devices (Tesselations) are used. Satisfying Tesselations are then supported into device manufacturing. With Tessel, once you've tested your idea, you can scale it up and sell your device.
