What is it? DSA Scientific is a group buy of keycaps featuring themes inspired by TI calculators. Who is it for? If you like the colours, then it's for you! This keyset is aimed at common layouts from full-size down to 40%. The design Various design choices have been made to capture the essence of TI scientific calculators and provide the best typing experience:

  • LaTeX styled novelties (including a reduced Planck constant key for your Planck board)
  • Colour add-ons and alternates for all tastes
  • Homing bars and dots instead of scooped keys
  • Doubleshot legends that do not fade
  • All-in-one 40's kit

  • Includes a small colour pack

  • Planck / Preonic layouts

  • Covers Vortex Core, MiniVan, JD40, JD45, Sebright, AMJ40 and anything in between

  • Covers most and includes Homing dot "5" and extra "Calc" and "2nd" keys

  • Compatibility for various bottom rows
  • 2.25u and 1.75u "Shift" keys
  • 1.5u "2nd" and "Clear" (compatible with Vortex Race 3)
  • 7u spacebar

  • Various constants and operators, namely pi and h-bar (reduced Planck constant)
  • Deep teal 1.25u modifiers for complete bottom row coverage (combined with TKL's yellow "2nd")

I'm very pleased to see a 40% kit for this. I have a lot of keycap sets but I've been struggling to get most of them to work well on a Minivan due to sculpted row sets being a bit inconsistent on 40% layouts. This set might be just the thing I need. 👍
Absolutely gorgeous.
I honestly remember having one of these lads in grade 8. Now i'm in grade 9. This keyboard set still brings back some of those nostalgia.
The novelties are incredible—especially that ħ keycap! I dream of someday having a nice set of Greek alphas in the vein of your π and φ novelties. Any thoughts of doing something like that down the road?
Thanks! It is a possibility... but first things first. As mentioned in prevous comments, I would like to see the high contrast set and TI-83 kit (slate blue instead of teal). All hypothetical at this point. The ħ key is also my favourite :)
I would also love to see the slate blue variant! That's actually the calculator I grew up with, so it hits closer to home. With things like the failure of GMK Greek Olivetti, I've really been on the lookout for anything Greek-related. The "math" font used in DSA Scientific is the most gorgeous I can think of for these letters! I'd love to stay updated on when/if you ever feel like it's a feasible set to produce. Being a physics student who loves quantum mechanics, I think I could actually find practical use for the ħ key!
Here comes a late suggestion. I like the '2nd' key (mainly because I remember it from my TI-83 Plus) and would like to use that key in favour of the 'lower' key. But there is no equivalent key to replace the 'raise' key with :( How about a green key that says 'NUMS' or something? (like the 'ALPHA' key on the TI-83 Plus)
Or, since you've used green instead of blue/purple for arrows and such, the NUMS key could be blue/purple.
It was the initial idea to have a TI-83 kit, but it was postponed with the rest of the high contrast/slate blue options... The colour code for the 'Alpha' key would most likely be VAF, which could kind of clash with the deep teal Pantone. It cannot be slate blue since that is a Pantone as well and not worth it for a single key. We did spice up the raise/lower keys with yellow legends, at least!
ETA 2 weeks on group buy launch! (╯°□°)╯︵ ┻━┻
Im not sure if this is too helpful or not but I've seen other people mention this. If there was an extra novelties kit with more Greek letters (especially the ones used in calculus!) I'd be super willing to support it <3 EDIT: I do want to also ask, I've seen some renders such as the High contrast / slate blue (TI-30XIIS) from geekhack, specifically this:
Will these also be available? Or this be sticking to the Grey / deep teal (TI-30Xa)?

Exactly. The initial idea was perhaps a bit too ambitious so we removed the lighter option. I'm open to running it in the future if the grey set does well. As for the greek letters, unfortunately the kits are pretty much final (except for minor tweaking). Many people wanted more options (myself included), but we settled for simpler kits. At this stage, we are just waiting for a launch date from our vendor...
Thats perfectly fine! Thank you for organizing this! Im so excited!
This set is beautiful and Im super into it! I especially like this considering how much math I've done this term and all the math courses I have left <3 If it was not clear by now, I would love to support this set!
Amazing, thank you!
Any update on the GB date?

Not working that hard... just waiting for paperwork in the mail :P
Work harder postal workers!
Love it! I had that calculator!
Added a new render, featuring the upcoming PrimeKB Prime_E ergo 40%. For fun!
Any chance of getting a homing bar on the "Down-Arrow" key?
Load 1 more comment
It would be really cool to have the regular arrows come with a barred down arrow (or even include a second down-arrow key (with a bar) with all kits that come with them). I think this would be nice for all keyboards, and would be extra nice for Vim users with no dedicated arrow keys.
I don't dislike the idea...
Norde and Dvorak/Colemak kits added. These will be low MOQ (15 or 25)!
Looking at the renders it seems that the big spacebars are convex while the small ones (e.g. 1u and 2u in the otho-kit) are concave. Is it so on purpose?
Only the long spacebars (6.25u and 7u in this case) are convex, the rest are concave spherical. This is a specification / limitation of the manufacturer (Signature Plastics). All DSA keycaps are like this...
I see. Thanks for clarification!
This is an absolutely beautiful design! Could you consider adding right modifiers to the Planck kit to use instead of the arrows?

Yes, I have thought about it but omitted them for several reasons:
  • Extra cost
  • Low demand
  • Alternatives available (novelties as you mentioned)
  • Colourway (ratio of Teal to grey)
My main priority is keeping these kits affordable. Ideally, there would be many more 1u options and kits overall, but this one's going to be very distilled. Hope you can find something you like!
I'm glad to know that you thought about it and made a conscious choice. I agree that lowering the cost for the most popular configuration, while providing other subsets with 1u keys is a good solution 👍
Just a tiny update: As mentioned on geekhack, the group buy should launch early next year. It's not too late to leave your comments and vote. I will soon update this post with the international kit. Cheers
So stoked!
This will hopefully go well with the teal cable over here:
This is noice.
V strong concept, love it!
pretty excited for this set! I never realized how aesthetically pleasing a scientific calculator themed key set would be, good eye!
When will this set release? Reeeeeeally can't wait!

All the 3D models are based on real boards. The 75% is a Vortex Race 3, which I haven't tried yet. It has 1.5u Esc and Delete keys (offset F-row) that make it difficult to find custom keycaps for it. But this set supports it!
wow thanks for the reply, very appreciate it. : D
I'm looking for a Norde / international kit template, any suggestions? The legends would be double (two symbols only) like the rest of the keys.
Sounds good! As for suggestions, I guess the usual NorDe kits à la canvas will please pretty much most people. If you're feeling generous towards us europeans (or at least every european country besides the UK but I may be wrong) maybe add a mono comma key to the numpad or NorDe kit analog to the mono dot key that comes with a numpad kit - of course that's just a minor detail but I'm sure I'm not the only one who would appreciate this :)
Any chance of adding an extra greek legend/key to the novelties? Perhaps rho(ϱ) or sigma(Σ/σ) ? I just realized that even without an international kit, I could buy the novelties and use the greek letters in place of the extra alphas, and my language/layout has 5 of those compared to the standard ones.
Hey, sorry for the late reply. There's more chance of an international kit happening than extra Greek letters... there are too many of them and no justifiable way to choose. Omega, epsilon, mu, lambda... It's about keeping the kit minimalistic. I only added phi to make a foursome and because it's viewed as a "universal" constant as opposed to some variable. Of course, in an ideal world there would be a complete Greek kit and perhaps many other options.
Can we get arrow keys to replace HJKL? Pretty please?

My personal preference would be for an arrow kit that fits that row, but I could live with HJKL with arrows on them as well!
Oh it's DSA (ie. equal profile) so the arrows fit anywhere...
This looks amazing! Makes me wish for an HP12c-inspired set...
Looks really sharp!
Would look great on my Vortex Race! Very interested!!!
The Race 3 reminded me of my Thinkpad keyboard. Hope to try one.
With uniform profile I can live without all the international keys, but need that ISO... (Actual scientist here and want this kit!) Even if you price it up at lower MOQ.
Yes! I'm sorry, it was an oversight on my part. There is an ISO kit, I just forgot to attach the image!
