devolution of the wp34s label---or fun with colors


i'll post snapshots of all three on an actual calculator once i've laid them all out.

version 1:

version 2:

version 3:


Opinion: Version three is more pleasing.


Opinion: Version three is more pleasing.

I agree, I prefer version 3 as well.


I also like version 3.

Things I like: the pi symbol, the sigma symbol, the separate Cy,x an Py,x labels.

Nit-picky things I would change: the slanted 1 with serif in both instances of 1/x, the x with a bar, the x in |x|, and the y with carat are not the same as the other lower case x's and y's, and I would raise the x in 2x and 10x.



and I would raise the x in 2x and 10x

... and in ex as well. And center lower case pi.

those are excellent points! you look at the monitor too long, everything starts looking the same.

that's why a different set of eyes always help.


I like version 3 too, although I agree that this is nothing more than a personal aesthetic opinion.

But, and I know this looks too obvious to be a mistake, so there must be a reason I missed, why is there two entries for 1/x, Sigma+, Y^x, sqrt(x), a b/c ? E.g. 1/x is over the B key in white and above the / (divide) key accessible with "f".




As long as there is no LBL A to LBL D in programm memory the keys A to D will act as Sigma +, 1/x, y^x, SQRT(x).

As soon as there is one of LBL A to LBL D defined the corresponing key will A to D will call the programm and the "white fuction" has to be called the alternative, shifted way.




One could have the g-functions on the buttom of the keys and leave their colour blue, the gold f-functions and the green h-functions above the keys.

...or rename h to something completely different, use a symbol.

Just for those who are familiar with the Voyager series. ;-)

But at the end, the WP 34s neither is a "genuine" Hewlett Packard calculator nor is it a Voyager series calculator. Why not try something different?


Is anyone interested in a transparent overlay for use on a repurposed HP 30b?

Exactly what I was thinking. I'm very interested!

Yes, I would like to see that.

Color choices may be challenging. The keys themselves can stay the same, white for primary function and blue for the h-shifted functions on the lower slanted portion. I think that black will just about have to be used for one of the keyboard-plane label colors. If the yellow-gold that has been used for the f-shifted functions on the black overlays shows up well on the silver background of the 30b, f-shift could stay that color and g-shift could be black. If yellow-gold does not show up well, I’d say use black for f-shift. That leaves the g-shifted and alpha labels. Not sure if green will show up very well on the silver background. For the default functions of the A, B, C and D keys, I might suggest something like below, i.e. white (edit - as Eric points out, this will not work on a clear overlay, so it will have to be siver) labels inside black boxes, to emphasize that these are primary key functions when active.

White labels inside black boxes on a transparent overlay?

What kind of printer prints with white ink?



Oops. Guess that would be silver labels inside a black box.

What kind of printer prints with white ink?

A very expensive one?

#35 if only I could fit that in my apartment. :)



LOL! at least you can purchase it. :) i have neither space nor moolah to even consider one.


Come on HP ... make us a custom set of keys and faceplate. ;-)


Sorry, we know they won't do that - the bias to pay is too high.


The consensus seems to be for #3, but as someone who is red-green colorblind, those two colors for f and g are difficult to distinguish.


I like #1. There is a certain retro appeal to it. It is also more readable in low light.
