I like space, rockets, spacecraft, amateur radio, and science stuff. Professional interests include SCADA and PLC programming.

The Original Movie Soundtrack for the movie Hackers (1995) was a great arrangement of kickass music.

I played this CD so much.

Yeah, that panhandle through the pine forest is longer than you think. I used to go between Huntsville and St. Augustine annually, so I feel you.

I'm gonna be thinking about this guy the next time I turn the knobs on my manual antenna tuner.

I am amazed at how clearly this old film explains SWR and impedance matching. I wish I had watched this years ago.

Blue Origin was awarded a contract for the Artemis 5 lander in 2023, so they're presumably already working on that.

I remember listening to the early local radio shows on September 8, 2009, when Obama was going to give a Presidential address to schoolchildren. People were losing their minds; keeping their kids out of school that day, so they wouldn't have to hear a black man speak from a position of authority.

I'm used to the VFD vendor sending out a person to set up the pump curves and stuff, and then giving me the Modbus addresses to interact with.

I'm just an systems integration / SCADA contractor for wastewater plants and get the usual anecdotes from operators about weird stuff getting trapped by the bar screens. Mopheads, turtles (!), etc; but the most chilling thing I ever heard was the explanation for why one plant had an old incinerator.

Is there any chance The Onion might have a braille edition through something like the National Library Service for the Blind and Print Disabled?

Just putting it out there to give me more motivation to study, but I'm gonna upgrade my amateur radio license to Extra (probably in August) this year.

Awesome! NASA used to make some cool mission posters.

It's in Pittsburgh, but it's also very old. They didn't have to switch to a W prefix, despite being east of the Mississippi.

I was hoping the recent polar vortex weather bringing temperatures way down might show an increase in activity per my muon theory, but it's actually been a little low.

I've got another Geiger counter kit, so maybe I'll stack it on the current one and combine them to identify muon strikes.

This reads to me more like a response to a scheme akin to Operation Plowshare to nuke a glacier to access copper deposits below the ice.

Being more active on the radio did not, as I assumed, reduce the measured levels of radioactivity in my ham shack.

So what else can trigger a G-M tube more often in winter than in summer? Is it Muons created by cosmic rays in the denser cold winter atmosphere? I'm thinking it's Muons.

I got the ham radio bug again in September/October last year and activated my station in the shack since then, checking into regular weekday nets and hunting DX contacts on the weekends. The shack has never had so much ventilation before. I figured this should wipe out the winter spike, but nope.

Prior to this past September, I pretty much only went into the shack during mowing season to access the mower and yard tools. The idea that maybe radon was just getting trapped during the winter months and increasing the measured radiation dose seemed reasonable. (I live in karst area.)

Searching for an explanation, I read that radon is the largest contributor to background radiation. This tube can't detect alpha radiation, but the decay products from radon will still set it off as beta and gamma.

Graph of historical data showing Β΅Sv/hour and daily Β΅Sv totals for a five year period. The recorded values show an annual low point during the summer and a peak in the winter.

Since 2017, I've had a 1990's vintage Soviet Geiger–MΓΌller tube in my tool shed / ham radio shack reporting in to my home SCADA system. It puts out CPM and, with a little math, Β΅Sv/hr. In SCADA, I fed that Β΅Sv/hr reading into a totalizer to get a daily Β΅Sv total. The daily totals seem seasonal.
