Yes, I don't have a lot of Greek-letter font choices available. Just to be clear, the greek letters you desire under the minus, zero, radix, Σ+ and plus keys are lower-case gamma, lower-case lambda, lower-case mu, upper-case sigma and lower-case phi, respectively, correct?

Speaking of fonts, I'm sure you noticed that I used the Century Schoolbook italic font for all lower-case letters on the keyboard. This closely mimics or maybe even matches the classic hp font for such characters. Any objections or comments on that change?

See my initial post for revised greek letters, hopefully closer to what you would like to see.

Probably a fair expectation. How's this: the overlay should be printed to the proper size so as to fit the actual calculator.
Just kidding, after measuring and double checking, I believe that if it is printed with the width in the 2.66" to 2.67" (67.6 mm to 67.8 mm) range it should fit the actual calculator.

That's continuously looking better. The last letter shall be a capital Phi.

Now to the lower case Latin letters: AFAIK, HP used something like Century Schoolbook italic font for letters referring to stack contents like x or y (or it should have used it at least). Where we don't talk about such items, you should employ the font you use for capital letters for sake of consistency. Thanks in advance for your understanding.

BTW, if you continue this way, eventually nobody will understand anymore why I was so excited some posts ago That's called the curse of editing old posts.

So you want a capital Phi to be sans-serif? (No idea if it is proper to call it sans serif, I mean the bars on the top and bottom of the vertical stroke. Two of the fonts that I have which produce this character put those bars on.)

Looking at a few HPs that I have handy, it appears that they (Hewlett and Packard) used the Century Schoolbook italic font for the stack content-referring letters, plus the "e" for Euler's number. They indeed did not use it for others such as "r", "s", "a", "b" and "c", so I will make that change with my next version.

Yes, that's true, but I don't want to use up all of my storage space here with a bunch of old versions, so I'll probably continue to update my original post. I will include notes at the bottom describing the edits for each new version.

I have a few MB of storage left, so I will go ahead and post the latest versions here. I doubt that the capital Phi will be satisfactory, but hopefully the rest will be OK. With these versions, I left out the gray key background, it looks a little nicer that way. I also trimmed them a bit, these should be printed with a width of approximately 2.63 inches (66.8 mm) to fit the real calculator.

Despite your prediction, capital Phi looks good to me. The only letter which went out of scale in relation to the others is pi now. This is a lower case letter and should hence be approximately the same size as other primary lower case letters.

The horizontal cut lines for the slanted labels look unnecessarily tight to me. I don't know if you can expand them - please take into account that those planes are ... hmmh ... slanted.

Thanks!

There is no need to place any cut at all between a primary and a secondary (f-shifted) label. Just FYI.

Agree that it did not look good. See above, I made it smaller and changed to a more pleasing (to my eye, at least) font.

The "cut lines" were in the original file from which I started. I don't know the exact relationship between these lines and actual cutting. For the time being, I don't want to fiddle with them.

I added a label to my post above.

Thanks, Jeff!

I'm willing to release the lower keyboard overlay for obvious reasons (the upper one won't get my release, its clearly only a CAC - a cheap ... copy ).

Certainly do not expect your blessing, but there's no reason options cannot be provided.

Religion, politics, and division symbols are the three things best left to each individual's conscience, and about which there is no point in arguing.

Don't forget taste (and good taste in particular).

But I don't agree about taking politics out of discussion - IMHO it's in fact a topic which should be discussed more frequently and widely, just not here. Division symbols, OTOH, are fitting perfectly here though I know it's a very hard and weary job to reach a set of unambiguous, consistent symbols (taking into account the history of science and metrology). Constant dripping will wear the stone, however.

Anyway, is anybody going to contact Eric?

The gray lines were purely reference lines for me to know the maximum "safe area" for labels so they wouldn't be too close to the edges of the keys or go over the angle in the middle of the key. They were not meant to be printed.

I suggest that you delete the layer with the gray boxes before generating an image for printing; that's what I always do.

You could start a poll about the division symbol.

Thanks, Eric, for your advice. Which tool do you use for that graphics? I don't see any layers unvealed.

I use Inkscape for editing the SVG file. It's free and open source and not always the most user-friendly, but it seems both stable and capable.

I can't cut directly from the SVG files. I export them to PNG, then put the PNG file into the program that drives the cutter, and manually draw all the cut lines onto it. But despite calibrating, the cutter still doesn't cut in the right place, so with a new layout it takes a bunch of trial-and-error to get everything aligned right again.

I'll probably make some 31S overlays soon. If someone has an SVG already that will help out, otherwise I will make one from scratch like I did for the 30S a few weeks ago.

Hi all,

As interesting and amusing this thread is, I am a little bit lost after reading a few pages of posts.
Is this 31S a new project, or are we just brainstorming an hypothetical RPN calculator?

I am now in the process of building one WP-34S (late arrival, I know...).
I am always looking forward for another open source calculator projects, like the more powerful WP-43S project that has already a site in the SourceForge portal, despite showing no information at all.

All the best,
Jose

Eric,
I created mine as SVG using Inkscape (agree that it is not user friendly), then exported to png for presentation here. The two version (differing only in division symbol) are in the attached zip folder. The only problem is the font for the greek characters. None of the fonts available in Inkscape look good, so I edited the png images to make decent looking characters.

Hi Jose,

Yes, this is a new project which we have almost completed our initial version. If you would like to beta test it on a windows emulator or to get the flash image to try it on a 30b device, you can visit the 31s branch on the sourceforge page:

http://sourceforge.net/p/wp34s/code/HEAD...hes/wp31s/

If you are using Linux, please PM me and I should have a Qt emulator version ready for you to try this weekend.

Most of the WP-34s team have had a hand in this project. Sanjeev and I have done a lot of the keyboard reassignment work and various other tweaks and adjustments. Walter is a key author and has guided us all on design, keyboard layout, and is producing a manual for it (similar to the WP-34s manual).
