3D Print Training

I recently (8/2020) received a request to teach three-dimensional printing to a middle school age student.  I felt a bit flattered. I decided the teaching offer needed a bit of thought on what that task requires. I have presented my (rambling) thoughts and concerns in this article:

I have a somewhat “natural ability” towards understanding electro-mechanical devices and complex process solving. Skills required to “master” 3-D printing. I am not sure if “natural ability” just means I don’t remember being taught formally.  We all learn through some process. For me I know it has not all been through a structured formal classroom environment.

However, I have spent a huge amount […] Continue reading » 3D Print Training

Mindless Wandering?

I mentally wander off while looking at the things I like to make, wondering if I can do (make) them better. Kind of a wondering wander I suppose… Ha!

Tool lust is something of which I am well aware. I love well made good working machine tools. I actually, love any tool that works well for creating the tangible items I create. I assume it is a normal desire for any creative person.

That kind of lust does need to be understood and kept within reasonable bounds. How I manage it is a mental exercise. I examine the reasons for the lust (desire) and compare with my present situation.

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…

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
