Carbon Monoxide!?

Weird. The smoke alarm went off, not incredibly odd when I am using the fireplace, but it wasn't the smoke detector. It was the CO alarm. I was totally surprised. It had never gone off as long as I have had one, over many many years. Yep, after resetting it a few times. It was getting a reading over 200 ppm CO. When I took it downstairs I got a reading near 300 ppm. I started getting light headed at this point. After thinking maybe the furnace heat exchanger failed and puzzling around a bit I figured out what happened. As part of the huge winter storm that recently covered almost half of the US, we lost our electricity. So, being well prepared, I rolled out the generator and started doing what I normally do. The generator (although it was completely outside) was creating CO to get in the house. Using the fireplace draft (and possibly other leaks) the whole house created a vacuum around the seal of the basement garage door. After the CO got into the house the forced air heat...

Easter is here. The weather is perfect for an Easter day. I have been working (for regular work) this weekend. There is so much to do.

I had a birthday a few days back. It was relaxed. I have been better at relaxing.

I did have time to build a Pedestrian Horn for the leaf. Supposedly, a few EVS such as Opel's Ampera have these pedestrian horns. The leaf did not, but mine does now. I used a small piezo buzzer, a push button, a small fuse and a couple hours of my life. There is a small accessory battery in the leaf so there was no rocket science trying to find a decent 12VDC power supply. The leaf is so quiet sometimes folks don't hear you behind them when they are walking. The regular horn is too loud when you sneak up behind a pedestrian. It is nice to have a quieter, friendly noise maker for this need. I felt good that I accomplished this small project without a single trip to the store for parts, tools or anything. I had it all in "my inventory stuff".

DJ and I climbed Stone Mountain today. Stone Mountain is an "impordent" part of Atlanta life. In any culture high places often have spiritual significance. No different in the modern-day growth-region of Central/Northern Georgia. It is an interesting walk. Stone mountain is a largely monolithic mass of granite. I had become familiar with the obvious out-crop just like the skyline of downtown Atlanta. I see it from the cockpit of my C-172 as well as the very-top overpass of "Spaghetti Junction". The walk gets steeper as you get nearer to the top. My altimeter watch indicated that we scaled a 70 story building, albeit in nature. I saw no one turn back. That also seems to be part of the culture. People as everywhere around here are openly conversive with strangers. It is a regular walk for exercisers and urbanites that need to do something different. It is close to Duluth and Atlanta. It took about 30 minutes by car to get there from Duluth. We spent about 2 hours on t...

Llama Lying Down Plush Fawna is Walking!! She was outside the llama house this morning. I thought that would be great so we left her out all day. Tonight when we got home she showed us how she can get up and walk about 10 steps or so!! She is definately showing signs of improvement today. Now we have the problem of trying to control the patient and keeping her in bed when she should be in bed. Good problem.

I had an job interview yesterday (the second one) things seem pretty good. We will have to wait and see where this goes. I scoped out a couple of old mills in the country as well. I located the Solon Pond Mill (in my book) and the Smithfield Flats Mill (not in my book). The Smithfield one is a large mill with a very good sized wood dam. It appeared to be in reasonable condition, albeit wood construction. It is definately a cool place. I took a few digital photos.
