I've always been curious about the two holes on ungrounded NEMA 1-15 plugs (Type A). There they were, one hole on each blade -- what were they for? When I had to make an electrical connection inside a junction box a few days ago, to power up a little adapter for a network camera, I thought: why … Continue reading What do you think of this?
Here's what I keep saying to every friend and acquaintance who visits my house: you definitely need a voltage stabilizer if you live in Romania. Around midnight last night the current started fluctuating wildly. Our UPS units were going crazy, clicking and kicking on and off, trying to contain the power fluctuations and cutoffs.

It was, as they say, a dark and stormy … Continue reading Pitch black darkness

This is Congressman Chris Van Hollen, the man that represents our district on the Hill. He's got our heartfelt thanks and gratitude. Do you want to know why? My wife and her students had to suffer for seven months at her piano studio -- without heat in the winter and without air conditioning in the … Continue reading Thank you Congressman Van Hollen!
❗ Updated 5/27/2008: It has now been a month since I wrote this post, and Pepco still HAS NOT fixed the electrical panel. This makes it 7 months, which is simply unacceptable. I am going to write to Chris Van Hollen, our Congressman, to see if he'd like to get involved in the matter. ❗ … Continue reading Pepco fails to fix store's electrical panel after 6 months
