That signal is dumped through a dual opamp. He swapped in several different types of photodiodes and settled on the … Read the rest
The team from Tech-On has taken the time to teardown two interesting microprojectors. The first model they tackled was the Optoma PK101. It’s based around a digital micromirror device (DMD) like those used in DLP. Separate high intensity red, green, and blue LEDs provide the light source. A fly-eye style lens reduces variations between images. They noted … Read the rest
