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?

The Science of Troubleshooting

Troubleshooting requires a knowledge of the why and how of proper behavior or operation. I don’t troubleshoot human problems as their how and why is very complex. I do enjoy troubleshooting things mechanical because machines don’t involve emotion in their operation. At least not yet.

Controls have been my specialty for most of my life. The last part of my working career was managing construction projects involving building (the structural kind) energy management systems and making sure they operated as intended. It required intimate knowledge of the why and how mechanical systems operate.

The ability for humans to operate complex systems (operators) and the ability to troubleshoot complex systems […] Continue reading » The Science of Troubleshooting

All Things Plastic?

Feeling rooked?

I am writing this as I think the “blush” of a new love has worn off. The love was infatuation with the process of three-dimensional printing. I truly like using the process but now only for purposes where it makes real sense. Printed plastic parts have a place in many things I like to make. That’s not going away.

I have also made a huge box full of useless plastic junk just because it was possible. Yes, it was fun. But it is still useless junk. I gave most of it to my young granddaughter as “toys” to play with. I think that qualifies me […] Continue reading » All Things Plastic?

IOT – Internet of Things

Internet Of Things

I stumbled onto and watched an intriguing cable network channel containing programs about Cyber-warfare. As all these specialized channels have become, they are more about drawing in viewers such as myself, than presenting impartial reporting. They all have an agenda, that suits their purpose.

That understood, it still presented a story, many stories , that  need to be heard. Most people will not understand what was shown, but people like myself, raised in a developing world of embedded computing, and have worked in the industry, know exactly what was being said.

Many and perhaps most of the electrical appliances or devices we buy today […] Continue reading » IOT – Internet of Things

A Creative Thought

Just finished mowing my yard, edging, trimming, the whole works. Good aerobic, couple of hours exercise for a 70-year-old male, in the Texas humid 85-degree heat. Far better that the 100 plus degree days we were having.

I am now re-hydrating with a bottle of orange G-Ade thirst quencher and have turned on the computer in my air-conditioned home office, checking emails and making sure the earth is still revolving. Don’t want to miss the eclipse in eleven days or so… The propaganda machine (TV) says it is a first full eclipse in the USA in 99 years but that is BS. Maybe the first that crosses the entire […] Continue reading » A Creative Thought
