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

Urban Drone Delivery Systems?

I am certain that widespread urban and suburban “Drone Package Delivery” is a system that will never be implemented. It is an urban legend/myth that is perpetuated only for its publicity factor.

Technically, it is possible. So is the flying car. They are both in the same category. Technically possible, feasibly impossible.

Imagine a kid running out the front door, smacking into a drone hovering a few feet off the ground with sharp knife blades at eye level spinning at 20,000 RPM. (The propeller lift system)

It is also (at present) a one package per trip system. Drone size is dictated and limited by fixed and absolute aerodynamic and power requirement […] Continue reading » Urban Drone Delivery Systems?

Sign of the Times

I had to spend some of my hard-earned retirement funds on a new doorbell button. It’s a bit more than a button. It is the “Ring” video monitor doorbell button.

Halloween is here, and it will be fun capturing the visitors, but that is not the reason I made the investment. We are in an age of front door delivery. A lot of services leave packages at the door. Some ring the bell and some just drop and run. A few will knock. There is no consistency, not even with the same carrier.

Amazon and UPS are the better, as I usually get an almost instant text […] Continue reading » Sign of the Times

Filters

My furnace, actually an electric heat pump, wasn’t keeping up to holding temperature too well. Checked filter. Oops… went a bit too long. Reminder to others, check your filter now. Very dirty filters will definitely reduce system efficiency (higher operating cost) and could damage equipment. Don’t put it off. Also don’t run without filters if you have a heat pump or air conditioning in your system. A few days won’t hurt but all season could plug indoor coil fins.

After 50 years in the HVAC business, I have changed and installed a lot of filters. Even electrostatic filters usually have an after filter that can get clogged due to […] Continue reading » Filters

The BBB stands for Bacon, Baloney, Bagel and well, Schmear is Philly Cream Cheese. After a hard morning casting and polishing silver, I realized it was after 1:00PM and I was a bit hungry. So I scouted around in the frig. I knew I was out of sandwich bread […] Continue reading » Ramblin’ Dan’s BBB & Schmear Sandwich
