Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A team of Chinese scientists has used semiconductor “quantum dots” to develop a vision sensor that adapts to extreme light changes faster than the human eye.

Taking a picture with a single photoresistor is a brain-breaking idea. But go deeper and imagine taking that same picture with the same photoresistor, but without even facing the object.

We have demonstrated a CMOS image sensor (CIS) with nano-light pillars (NLPs), which is metasurface-like structures, on a 0.8 μm-pixel sensor to enhance quantum efficiency. By employing a unique ...

In this paper, we present the TacShade: a newly designed 3D-printed soft optical tactile sensor. The sensor is developed for shape reconstruction under the inspiration of sketch drawing that uses the ...
