Cheap homemade 30 MHz – 6 GHz vector network analyzer

Introduction Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to matter and distributed effects need to be taken into account. VNA can be used to analyze reflection and transmission coefficients of circuits at high frequencies. For example ideally …

Wi-fi browser controlled servomotors

This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser (Firefox, for instance). This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was …
