Thanksgiving

Thanksgiving

And Happy Thanksgiving in 360 degrees. 😉 A couple of outside pictures at night, as I was curious how well it would work.

While it can do video, it seems in picture mode it uses a pretty slow exposure.. in the entry pic you can see Audrey and a few other little girls zipping by.

I got my stellar spectroscopy equipment setup tonight and took it for a spin. To start I shot Vega (Alpha Lyrae), which is a spectral A0V star that is great to use for calibration, and 5th brightest star in the sky (in my particular sky it was the 2nd brightest). Vega is a relatively close star being only 25 light years away.

In the graph you can clearly see the hydrogen balmer absorption lines (marked with the blue vertical lines), as well as the wavelength of the lines.

I’m looking forward to doing some spectral analysis of other deep sky objects.

As an aside, I’m going to use the same stuff to do some spectral studies of the different LED light bulbs for the new house. More on that coming soon.

A bunch of 3D pictures of the current house progress. I’m thinking this would be a cool camera to have permanently installed in a few locations outside and streaming to my central recording archive.. it sort of makes the ultimate security camera.

I did a walk through of the house in 3D. I need to remember to keep the front of the camera in the primary direction. It is kind of cool that you can look around while I am walking, and also while the video is paused. I didn’t do any narration as there were lots of people working, and music.

Exterior paint is perhaps 90% done, and interior drywall installation is about the same. The drywall guys are fast! >10,000 sq ft done in about 1.5 weeks, perhaps 8 guys. Next up is of course taping and mudding, then window/door trims, then probably the wood ceilings.

I think February is looking possible. Woot!

Lightbulbs

Lightbulbs

I picked up all of the local options for LED can lights, and ordered 8 more off Amazon. I am going to build a test fixture and do some measurement and analysis, as I don’t trust what the box says.
