I'm still studying for more engineering knowledge. But I'm trying to apply my limited knowledge to better solve problems

What I need to find is a way to accurately measure 3 things that are all related - so I can develop a solution to problems

I'll explain why , and what , and then I'll ask for suggestions on how

I'm building a glockenspiel out of copper tubing. Eventually I want to put a micro controller on the thing to play a specific tune, and then use it as a door bell chime.
I'm wanting to use Pythagorean tuning instead of evenly tempered like a piano (need to research the right audio frequencies)

So right now I'm using an app on my smart phone to measure the beat frequency after sticking - so I can approximate the length needed to acquire the desired notes later. Is there a better (more accurate method)

After how would I measure frequency shift over time? (Amplitude change as well)

Also I'd like to tune the thing with a high q factor - so I can have the note sustain longer. I'd like to change to softer mallets to get lower q (faster damping)

But the question I have is how does one measure q of mechanical vibrations with reasonable accuracy (and repeatability)

Marble Stirling Engines are easy to build and fun to watch. The way they work also teaches you a lot of thermodynamic concepts. 

We show you our version of the engine and give and explanation of how it works.

Typical multi-body problem in statics: Two completely different problem-solving methods: the first method is the classical one that has been used to solve statics problems for the last 150 years; the second method comes from systems physics; it is a new and unusual but holistic method.

Hello;
One plane ride I had the idea to write a simple quick book on how to write proposals for science and engineering.  So I took out a note pad and wrote a simple 17 pages.

I wrote a book on proposal writing like it was a proposal itself.
I have some experience on larger robotics projects, so I think I can comment on the project process.  Above in the mosaic is some of them, not all.  To date, I've written awarded proposals worth in excess of $4million. One pl...

Heard about this back in 2013, thought it well deserved a re-share. 15 y.o girl invented a body-#heat powered #torch. http://bit.ly/1zPSIi0

The world VASTLY needs more people like her, especially at her age. :) #ClimateChange #RenewableEnergy

A century-old building in Iowa generates more energy than it uses, thanks to the engineering firm that now resides there. History meets the future.

Sad news from MakerBot.
MakerBot, the company that became a leading voice in desktop 3D printing by taking desktop additive manufacturing from build-it-yourself kits to refined consumer devices, has just let go of 20% of its workforce and closed its brick-and-mortar stores. According to reporting by Motherboard, the reduction represents about 100 employees of the Brooklyn-based …

please see my new LI post on transitioning from technical professional to manager
For this post, I am going to make a slight departure from our recent series of articles on technology forecasting and technology scouting (which you can still find here, here, and here) and speak about a subject of great importance to the careers of my fellow scientists and engineers.It has often been the general experience that when scientists and engineers attempt to make the transition into management, they may not do well.  Sadly, as a reward...
