Recently I’v got my samples of SN6505A, it’s a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input voltage as low as 2,5V – that makes it great for battery devices. It’s also nice, […]

First on the chopping block, the “EH1205”. Wait! What’s this? The original AC connector is mounted to the PCB. Yes, this has been repackaged! I think we can assume the approvals on the label are fiction. The current rating sure is. Note the ~5mm spark-gap in the upper left (~15kV?). Yes! Can you believe

As per the title of this question i’m trying to control an ac resistive load. So far i had little success and i’m experiencing “strange”, to me at least, behaviour from the triac(s) i tried. first of all i post a schematic of my test circuit (bare with it, it’s not a complete schematic, it
