A Far Red Bacteria Incubator

A Far Red Bacteria Incubator

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

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
