My solution was to utilize the WEBENCH tool from Texas Instruments to help design a low-noise, buck-boost converter in-between two RJ45 ports. That way, one end of their system could be powered by whatever […]

I managed to get through the early days of my hobby by using salvaged wall-warts with fixed voltages and fixed current limits. But when it came to testing my new LED panel for the V-I curve, I found it really cumbersome to […]
