WiFi Smart Power Strip Socket – Under My Control

By | October 12, 2018

I was looking for a remotely controlled power strip. Actually, I was originally thinking about wired/Ethernet connected ones as I had seen in some data center setups.

But those WiFi-connected strips… Read More »

I played with my UNI-T UT61E and Linux before. But now a friend pointed me to a little graphical display/grapher for the DMM data called QtDMM. It looked interesting but it did not work completely for my meter:-( So I looked around and found two source bases, one on github which was moved to Qt5… Read More »

Playing with that opens a whole new area of potential uses. But first, the printer has to be able to handle it.… Read More »
