Last Strike?

Thought I found all the lightning damage. Not so… 

I knew the power supply for the older Cetus 3D printer was burned out. Zero voltage output. I needed a new power supply to test the printer. I have two Cetus 3D printers as shown in the pictures, but their power supplies are very different.

The newer printer on the left has a much higher wattage supply than the one that has failed on the right and a different plug. I had to order a new power supply for the right-hand printer as it was definitely dead, with zero output.

The replacement power supply came today all […] Continue reading » Last Strike?

Big BOOM – II

This week started with a literal BANG!

Lightning again struck my house here in Frisco, Texas. This is the second time. First time was Monday June 29, 2009. A little over 11 years ago. Search “lightning” (upper right corner) on this blog for more information. (Yes, this blog is much older than ten years.)

This one was on Sunday morning August 30, 2020. About O500.  One hell of a wakeup for a Sunday morning. (Words carefully chosen…)

The bolt struck my nearly 20 year in-place vertical amateur radio antenna. Just outside the bedroom window. The vertical antenna is mounted above the lowest corner of the roofline on […] Continue reading » Big BOOM – II

Internet Outage

We experienced a two (plus) hour outage of our internet yesterday. Almost all our external communication is delivered by that system. The cable television, home phone line and of course our Internet data feeds are dependent on that connection. Its importance is second only to our electrical power feed. Our home is 100 percent electrical energy dependent.

The immediate effect was how quite everything in the house had become. The power was on but only the cell phones would communicate. The air conditioning was performing normal. The indoor temperature was still perfect. All our other electronic “toys” had become almost useless without their normal data feeds.

I liked the […] Continue reading » Internet Outage

What I Am…

Where I spent my “allowance” in the 1950’s.

Read a comment made by an old (youngish 66 year old) dude about his involvement with 3D printing. He said he is a retired engineer. The reason he loved 3D printing wasn’t from what he made. It was the complexity and constant challenge to learn and understand the technical process. The CAD; the item design; the CNC; the process; the hardware; the mental stimulation. It had to be complex and difficult or he wouldn’t be interested.

I realized I was reading my own mind. It isn’t about what I make at all. It is all about mastering the […] Continue reading » What I Am…

P(r)aying For Rain Water

After a hard summer last year of extended drought conditions, north Texas has been blessed (?) with double average rain amounts. This comes to us in severe thunderstorms and multiple tornadoes. Mother Nature has seemed to have left out nice long gentle rains from her bag of weather tricks. Like Morton salt, “When it rains, it pours.”

However it comes, the rain is welcome. The problem for me has been the electrical activity that an all but gentle rain produces.

We haven’t experienced a direct lighting strike again but we have endured power outages and lighting induced emf surges. The same emf fluctuations on the cable […] Continue reading » P(r)aying For Rain Water
