An IOT SMART Meter using ESP8266

An IOT SMART Meter using ESP8266

One of my first posts on this blog was regarding a 3 Phase Smart meter I had designed in my first 1st year of University. It was meant to be used within a network of many such meters to conduct thorough power grid analysis. It had a powerful DSP on it capable of receiving samples … Continue reading An IOT SMART Meter using ESP8266

Homemade Injection Transformer for PSU Loop Analysis

Homemade Injection Transformer for PSU Loop Analysis

Recently, I have been designing some SMPS and required some hardware to measure the actual loop response of the complete converters. People familiar with this area will probably know this can be done breaking the feedback loop of the converter and injecting a small AC signal and measuring the loop response at the output of … Continue reading Homemade Injection Transformer for PSU Loop Analysis

3 Phase WiFi Smart Meter

3 Phase WiFi Smart Meter

Back in 2015, after completing my first year of EEE at Imperial College, my tutor offered an interesting research opportunity. The project was to design an affordable but capable 3 Phase Power Meter. The meter was to be able to work in a sort of swarm/network and communicate wirelessly to a central server. The idea … Continue reading 3 Phase WiFi Smart Meter

Experimenting with Directional Couplers

Experimenting with Directional Couplers

Recently, I have been obsessed with home-brewing  RF/microwave test equipment. There is something so enthralling about building something that would help you build something else. Perhaps the most important RF instrument is the Vector Network Analyser. As the name suggests, a VNA can characterise a DUT. This is done in the form of Scattering Parameters. … Continue reading Experimenting with Directional Couplers
