Hot on the heels of yesterday’s FSR tutorial, Limor and Phil continue their Sensor Tutorial series with another crystal-clear exposition of a component, this one on the photocell (aka CdS, LDR, photoresistor). Great stuff, guys. Thanks! Photocells
In the Make: Online Toolbox, we focus on tools that fly under the radar of more conventional tool coverage: in-depth tool-making projects, strange or specialty tools unique to a trade or craft that can be useful elsewhere, tools and techniques you may not know about, but once you do, and incorporate them into your workflow, […]
It’s the simplest semiconductor device made. It ushered in the age of radio, the electronic valve that rectifies and regulates – the diode!
They electronically switch and amplify signals by harnessing the unique abilities of semiconductor materials. Their invention has transformed the world of electronics and accelerated our entry into the digital age. Behold – the Transistor!
