Metawave’s phase controller allows the heavy lifting required for precision beamshaping and steering control to be done in the analog space vs. pure digital.

Designed for single-phase or 3-phase meters, the CS5461A performs multiple measurements, including instantaneous current and voltage, instantaneous power, real power, apparent power, I RMS and V RMS.

One displays hours, the other, minutes. The analog meters are simply driven by the PWM outputs of the Arduino. It’s not a hugely complex project, but it teaches so much.

Analog and digital features are complementary, and in certain cases work well together—even in the same unit with hybrid analog-digital meters. Since the early 1980s, meters have been offered ...
