How I accidentally fixed the garage door

My garage door wouldn’t go down. You know the drill–you push the button, the door goes down for a few seconds, then reverses course, and maybe your opener blinks at you a few times. Not all garage door openers do the blinky thing though.

The reason is simple. The safety sensors couldn’t see each other, so they assumed something, or worse yet, someone, was in the way, in danger of being hit by the door, and made the opener reverse course. As annoying as a door is that won’t close, a door that mashes stuff is a lot worse.

My sensors couldn’t see each other because we’d moved some stuff around and, I guess we bumped one of them. Read more

Enerlites HOSS: an occupancy sensor switch without ground

The Enerlites Top Greener HOSS is an occupancy sensor switch without ground wire requirements, and it’s pretty cheap too, at $12. A Lutron switch costs almost twice as much.

But the HOSS does come with some compromises. The HOSS does require a neutral (white) wire. But most switch boxes will have the whites in there and accessible, so that’s not a big deal. It’s also a bit trickier to wire than a Lutron, and it doesn’t look as nice.

That said, it’s nice to have an option for older houses that may not have a ground connection available. People in older houses need energy savings too. Read more

Diaper raid!

This past weekend was the annual Scouting for Food drive. My oldest son participated, and I was proud of him because he complained a lot less than the older kids.

In fact, he was perfectly happy running up and down people’s driveways, picking up bags, and putting them in the trunk of our car as I drove 3 miles per hour with the hazard lights on.

But somewhere along the way, something started to smell funny. Read more

A new way to measure reliability and quality of hardware

A new way to measure reliability and quality of hardware

If you’re in the market for some new PC gear, it helps to measure reliability and quality of hardware. How do you measure that? How about buying the one that induces the least buyer’s remorse? That’s an approach you can take with the data from Hardware.fr. It’s in French, but Google Translate works.

This doesn’t measure long-term reliability–only DOA rate and short-term reliability–but it’s data I haven’t seen before, so I think it’s a welcome resource.

Comments are working again

One of my very earliest readers alerted me today that comments were broken. I traced the problem back to WP-Spamshield. I disabled it, and comments are working again. I hate to lose that plugin, but comments are important, so I’ll search for a replacement or a fix action. In the meantime at least it’s working.

Here we go again. Net neutrality is not Obamacare either.

To nobody’s particular surpise, yesterday president Barack Obama endorsed a form of net neutrality. And immediately, Sen. Ted Cruz (R-Texas) came out swinging against it, calling it, “Obamacare for the Internet.”

Sen. Cruz appears to have either failed to read, or refused to read, the four-point proposal, which is short and simple enough to fit on an index card, if not a business card. He also failed to discuss the alternative–and there is a perfectly fair alternative to net neutrality.

How to check a train transformer for safety

How to check a train transformer for safety

In spite of what a certain O gauge magazine tells you, vintage toy train transformers aren’t inherently unsafe to use. Age can take their toll on them, so you want to give them a good safety inspection, but as long as they pass the safety inspection, they can give you a long, productive service life. Here’s how to check a train transformer for safety.

All of my train transformers are at least 50 years old, and I expect my sons to inherit them in workable condition. Read more
