Combining Cor Van Rij's JFET test socket with two DMMs, a current limiter, switches and a wall wart yield a simple, accurate JFET tester.

Abstract: This article presents the methodological process to be followed in the design of signal conditioning circuits for optical sensors (position sensitive detector (PSD) or photodiodes), which ...

Abstract: Electrochemical sensors integrated with CMOS circuits play a pivotal role in quantifying various chemicals across a huge spectrum of applications, prominently in distributed diagnostics and ...

My initial goal was to have a remote display that would show multiple kind of information and run reliably 24/7. Can be connected to the local network via WiFi and controlled via REST API or Websocket ...
