Theadora’s epic journey

Through a World of Warcraft discussion message board, I heard of a research study being conducted by West Virginia University on the relationships between videogame players and their avatars. In a "what the hell" mood, I responded to the survey with a story about one of my WoW characters. I thought the story was minor, but to…

New York Primary Elections

The New York Primary Elections are on Thu, Sep 13th. We've learned in recent years that primary elections are very important; the results of those elections bear on issues like who the superdelegates are at the Democratic National Convention. I've been doing some web research on the candidates. I found Ballotpedia to be a very useful resource,…

Otter Voice Notes

I'm still working on the biography of Isaac Bonewits, though I admit my progress has been slow. I periodically scan more documents from the last boxes of papers Phaedra sent me. One big issue with my research was transcribing interviews. I have about 70 hours worth of interviews so far, with still a few more to go.…

230V Air Conditioner and HomeKit, part 10: Are We Done Yet?

Of course not! The setup I described in my previous post has an issue that's not obvious: the fans are on all the time. They're powered by the +5V pins on the Raspberry Pi. The fans were pretty quiet, but they were still audible in a quiet room. It was also a waste of power. I wanted…

230V Air Conditioner and HomeKit, part 9: The Box

I knew from the start of this project that I'd need to put all the components in an enclosure. This was to be a semi-permanent installation; I couldn't have wires and heat sinks dangling everywhere. Sam Groveman suggested this type of project box. I picked one that would be big enough to hold the solid-state relays along…

230V Air Conditioner and HomeKit, part 8: Power Cords

Did you read part 7 yet? If you thought to yourself "I don't need to read part 7" that means you need to read part 7. (The exception is if you're a licensed electrician, of course.) Now I've reached the stage that Goldy is dreading: Working with power cords. The point of this project was to use…

230V Air Conditioner and HomeKit, part 7: Electrocuting Goldfish

In my previous post in this saga, I'd just reached the point when I start talking about power cords. Before I go any further, we have to deal with some practical stuff. Starting with my next post on this project, I'm going to describe how I worked with wires that carry household current. These lines carry 120V…

230V Air Conditioner and HomeKit, part 6: Solid-State Relays

In the last part of this overly-extended saga, I described how I got a Raspberry Pi to send signals to the pins on its circuit board. The next step is to get the signal from those pins to control the flow of electricity through a 240V power cord. I found several posts on the web (here's one)…

Wizard’s Staff

Like many folks, I have that box in my closet filled with cables that I keep "just in case." Today I decided to go through that box and toss out the stuff that I knew was obsolete or that I'd never use again. Sure, there was the usual batch of BNC cables and excess power cords. But…
