Ed Nisley, Auteur | 2018"Prompted by a reader's query, Ed became aware that you can no longer get crystal oscillator modules tuned to specific frequencies. With that in mind, Ed set out to build a "Channel Element" replacement around a Teensy 3.6 board and a DDS module." (Extrait de Circuit Cellar ...

Ed Nisley, Auteur | 2018"Today's small fans and blowers depend on brushless DC (BLDC) motor technology for their operation. Here, Ed explains how these seemingly simple devices are actually quite complex when you measure them in action." (Extrait de Circuit Cellar n°336)
Article : texte imprimé
Ed Nisley, Auteur | 2018"Continuing with the topic of stepper motors, this time Ed looks at back electromotive force (EMF) and its effects. He examines the relationship between running stepper motors at high speeds and power supply voltage requirements." (Extrait de Circuit Cellar n°334)

Ed Nisley, Auteur | 2018"Using inexpensive microcontrollers, motor drivers, stepper motors and other hardware, Ed buuilt himself a cComputer Numeric Control (CNC) machine. Here, he examines how the CNC's stepper motors perform, then pushes one well beyond its normal limits." (Extrait de Circuit cellar n°332)

Ed Nisley, Auteur | 2018"In Ed's november article he described how an Arduino-based tester automatically measures a resonator's frequency response to produce data defining its electrical parameters. Here, he examines the results of those measurements and delves into variable series capacitance as measurement aid." (Extrait de Circuit Cellar n°330)

Ed Nisley, Auteur | 2017"Using the full frequency resolution of a direct digital synthesizer chip outstrips the capabilities of floating point numbers. Ed takes a look at what's needed for high-resolution frequency calibration and measurements." (Extrait de Circuit Cellar n°326)
Article : texte imprimé
Ed Nisley, Auteur | 2017"Ed takes a look at the somewhat surprising parameters of quartz crystals operating in the low-frequency band. He covers resonator modeling, quartz measurement, low-frequency resonator measurement, and more." (Extrait de Circuit Cellar n°324)
