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
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
I have always wanted to build a fairly capable LCR meter that could cope with real world use in my own personal lab. This would mean reasonably good accuracy across a wide range of L, C and R. Fortunately, I got the time to do just that this year in the 3rd year Instrumentation module … Continue reading Low Cost High Accuracy STM32 FFT LCR Meter
Last summer, a good friend of mine from the Biochem department approached me for some help. He was conducting some research that involved studying the response of certain bacteria to various level of Far Red light. They needed a setup where one could embed multiple test tubes, each exposed to a different intensity of light. … Continue reading A Far Red Bacteria Incubator
