[Arao] wanted to measure the RPM of a spinning wheel using parts that he could scavenge from his junk box. A bit of thought led him to build a reflective sensor which can measure the spinning of a ...

Adding an additional fan to your PC is usually pretty straightforward, but as [Randy Elwin] found, this isn’t always the case with the newer Small Form Factor (SFF) machines. Not only was the standard ...

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...

From self-driving cars to facial recognition, infrared sensors are all around us and our novel semiconductor research is taking this technology to the next level. Phlux - a Sheffield spinout -has ...
