Same for other stuff on the web. Else it would not work.

What about an Android App?

Now to write a little program for windows. Could probably do a spreadsheet. Any interest in that? I wonder if I did one if it could be posted on the BCT site?

Nice work, good to know there are smart people posting.

The original AMP actually came with a bunch of formulas(8) to put into an HP-32s and a laminated cheat sheet to show you which one to use.

The app is easier though.

My calculators of choice have always been Hewlett - Packard and I have come to really appreciate the virtues of RPN as my personal faculties fade.

Writing a little program to save in the calculator was much less of a chore than making the calculation of the AMP v2 geometry - and that wasn't too tough. Given that the AMP v2 business is accomplished by the caliper measuring the change in length of the base of an isoceles triangle and that the difference is 152.40 mm for a change of 90 degrees, following provides the unique solution of leg lengths that make this work.

Where:
A = the change in base length
a = the angle opposite A
OA = the desired obtuse angle
C = the length of one of the equal legs
The solution for the leg lengths at an obtuse angle = 90 degrees is had by
A = 2C x sine (a/2)

At an obtuse angle setting of 90 degrees, a = 45 degrees. Therefore at an obtuse angle of 180 degrees, a = 135 degrees. Given these two known conditions, the lengths of A and C can be calculated as follows.
2C x sine (45/2) + 152.40 = 2C x sine (135/2)
C = 140.799 mm
A at obtuse angle of 90 degrees = 2 x 140.799 x sine (45/2) = 107.763 mm

Solving for A for a given obtuse angle is then
A = 2C x sine ((OA-45)/2) - 107.763

Solving for the obtuse angle for a given A is
OA = 2 x (arcsine ((A + 107.763)/281.598) + 22.5)

A simple program for the venerable HP 10C is then
fLBLA
45
-
RCL02
X
RCL01
-
fLBLB
RCL01
+
RCL02
/
gsin-1
22.5
+
2
X
To calculate A, enter the obtuse angle, press enter, and press f LBL A
To calculate the Obtuse angle, enter A, press enter, and press f LBL B

After all this, the good news was that the result corresponded to the APP!

Good suggestion.

The video is nice, but it doesn’t explain much how to use the AMP v2 and the app to perform functions in its 3 minutes and 41 seconds.

How would I set miter angles for dissimilar stock width for other than 90 degrees? Is the Circumference Calculator just there to be handy, or is there some AMP v2 specific use for it? I’ve more questions, but I think you get the gist.

Just a little cheat sheet would be nice for those of us who are hobbled by many years distant from practicing geometry in the shop.

Good News: I contacted the authors of PowerOne and received the following answer:


There was a bug in powerOne that kept the calculator from working correctly but only on iOS 4.2.1 devices. There is a month long story behind this bug. We were able to track down the problem to an Apple system call but, as it is an Apple call, there was no way for us to fix it. Because of that we had to end support for those devices. Then, just a week ago, we got lucky and stumbled into a fix. A new release is going to Apple today and will add back in support for iOS 4.2.1 devices.


So, if you gave up before on this App, try again soon!

This now works on all browsers. I do not recommend Microsoft's Internet Explorer 8 though. Modifications had to be made for this page to work correctly in IE 8, but it really looks awful.
Try:
Google Chrome, http://www.google.com/chrome/intl/en/more/index.html
or Mozilla's Firefox, http://www.mozilla.org/
or Apple's Safari http://www.apple.com/safari/
