Why wouldn't it be?

(You should.)

It looks like they are simply connecting to test points on the PCB that correspond to the relevant rows/colums for the keypad matrix - basically piggybacking the existing keypad.

I wonder if they have any plans available?

Do you have documentation on this? I had a very old project of mine that was halted mostly because I couldn't parse the keypad matrix on the CE.

As far as this keyboard goes, I love the idea of a math-oriented full keyboard, but I feel like hooking it up to a TI-84 sort of defeats it. It is very cool, though. The TI-84 is the way that it is, keyboard included, because it's inherently meant to be portable and durable. If you're going to make a full math keyboard anyway, I think I'd also want to slough off the restrictions of using a TI calculator. I would actually spend loads of money on a simple USB keyboard that enlarges the TI-84 layout to the scale of a normal keyboard, such that I can plug it into my PC and use it in other programs that are stunted by normal math entry like the Nspire student software, MATLAB, and WolframAlpha.

Next time I have disposable income to spend on my computer I'm definitely going to build a custom math keyboard. Probably in the form of a ortho-linear standard PCB turned sideways.

I am thinking about selling V2 fully assembled, but the price would match. (Rough estimate would be $275 for a felly assembled KE V2, calculator included). What are your thoughts about that?
A kit would be much more preferable for me. I would like to use my own switches and calculator and $275 would be a little too much for me.
If this becomes a buyable kit (IE I buy the keycaps, frame, and other little tid bits) while I supply the calculator, key switches, and assembly I would buy it in a heart beat

Yea, I agree, I think it would be nice to also offer just a kit by itself so people that like to tinker with stuff have the opportunity to make it themselves but in a more controlled environment. I personally really like doing these kinds of things but get kind of spooked when just doing it without a guide. I think I would still buy the fully assembled KE V2 if you only sell it in that form, but it would be nice to have the option to do it ourselves.

If it is possible to make a kit, what would be rough estimate for how much it would be? If you just do the fully assembled kit for V2, what would be included in it?
I would love to buy a kit! This is seriously dope my guy
I was just talking about wanting to build an 83+ keyboard in a mechanical keyboard group and someone mentioned this. I was thinking more along the lines of a keyboard i can plug into the computer to make debugging asm programs easier on TilEm2 (i was thinking of using chocs though) but this looks so beautiful, if you do another round definitely count me in!
How has progress been? I'll bet making the instructions has been pretty time consuming. Are your plans to print out a booklet and ship it with the kit or make it an online guide?
Thank you for the checkup, TLM. And thank you all for the continued support and patience with this project. I have been using my copy of this kit for a while now, and while I don't do much math these days, it has been an amazing machine to use, especially for playing games. I added a large 2200mAh battery, so even with the LED's on, the battery life is pretty splendid.

It has been a while since my last update. My hand is on the mend, and I just got the clear from my doctor to stop using my brace. With this newfound freedom, I spent 5 hours this past Saturday making the keycaps. Streaming the process on the #hcwp channel on Discord, I completed 96 of the 204 keycaps for the 4 kits. This weekend, I will do another 5-6 hour session and finish the rest of the caps. Thank you all who hopped on the stream and chatted for a while, it was a lot of fun!

The cases, screen bezels, and all other 3D-printed parts have been printed. There is a little post-processing to do, which should not be difficult to manage in the afternoons this week.

All-in-all, the shipping-out date for these kits is forecasted to be April 15th. I will contact the receivers of these 4 kits via Discord PM in the coming week.

Speaking of Discord PM's, I have been talking to a few people from the custom mechanical keyboard community to help realize the idea of a second run of these kits using manufactured parts. This will involve some design changes, which should also add some of the requested features. Details are still in the works, and I am still far from a finalized design for this "Version 2.0".

If you know anything about DFM, manufacturers to reach out to, or general tips for cut+bent sheet metal and multi-color dye-sub keycaps, please feel free to reach out. I am currently talking to a Chinese keyboard part manufacturer IDOBAO about running a set of keycaps, but I have a feeling it might be a bit expensive.



tl;dr: Thanks for patience, hand is getting better. Finishing the first 4 kits, shipping out on April 15. Currently in talks with manufacturers to do a larger second run.
wow, thanks for the update, it sounds like you're going to be keeping busy with this for a while, I was just wondering if you plan on continuing to update this thread or if there is somewhere else that we can get updates on this project? I'd love to hear more about progress and like what is going on.
