Last week I bought a consumption measurement device for 20 bucks. I wanted to know how much current is needed for various electronic devices I use at home, some of them on a 24/7 basis. I have got a home server running Linux, that I use as a NAS, print server, slim server (for streaming mp3 files to an…
