A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”
Sounded like the kind of math challenge I like:
Got a Call from Christopher today. “I do a lot of EDACs” I said. He said “what you really want is the CB37 Light Director Board“
And he was right.
To better understand the behavior of a Passive Resistor Inductor / Resistor Capacitor I built another excel calculator….
a whole semester summed up in one drawing
I’ve been calculating a lot of components in series lately for an ECR255 class. I’ve also had to graph them on impedance diagrams and a power triangle.
In an effort to better understand the math I made a calculator for myself. Here is it for you to use and enjoy. If you see any problems please let me know. It was designed in excel 2011 for mac… there WILL be compatibility issues and I hope they’re minor.
How it works:
You can fill int the info you have in the orange boxes. Once the boxes are filled in the calculator should fill in the rest.
If you need to modify anything else, it’s all dependant on the orange boxes. I suggest a goal seek by modifying and orange cell.
In the 70’s and into the 90’s WBS used a Schadow switch in almost every product they built. Different buttons required different offsets so “GOLDEN RULES” of design were made up so each engineer was on the same page. I found two of those pages the other day and was fascinated. These drawings are both done by hand and are admirable.
