Later that century, Columbus landed in the New World with three barely seaworthy boats.
Zheng’s armada, for all its grandeur, left virtually no imprint on the world
-- while Columbus changed the entire course of history.

A low-cost, open-source maskless photolithography stepper for microfabrication
Photolithography is a key part of modern semiconductor process flows, and photolithography steppers have been used for decades to achieve precise patterning for device fabrication. However, these tools are often large and expensive, which restricts their use to industry and well-funded university laboratories. In this paper, we propose a $3000 maskless photolithography stepper that is affordable, open-source, and easy to assemble. The stepper, which uses a Digital Light Processing (DLP) project…
