And boom, done.

About 19 inch long, 9 inch deep, 6 inch tall.
I left about 6 inch of pipe to the left so I can add another module, mostly photoshop related shortcuts/tools, using a  different teensy.
Unless someone wants the STLs right now, I wont upload those until I modify the right console to add the trackpoint under delete key.
The screws on legs are to fix it on the custom piece of wood that I added/extended from my desk.

Thanks, yes @nevin, all very stabile. Used E7 instead of D6 pin, now that I`m using this, I`m really glad that I did not give up and postpone it. Soonish I`ll start digging up old threads looking for some firmware for the trackpoint and its only a matter of time before I get that working too, after which I want to get into resin casting, perhaps make some money back, compensate from all those long hours I`ve had to put on this project

yes, i'm hoping to get back to the mouse soon too. finally looking like it might be possible.

resin... check out this video (it's a great intro into what's involved and the stuff needed) and posts here by theGlyph

and here's another one that was related, about casting 3d prints.

i'd love an interesting blank set like he did with the stereo set

guess I'm just surprised that there's so many keys in the key wells to have such common keys in a totally different cluster... to each their own!

@theKM haha, sorry if came out that way, didnt mean to be rude or anything.
The reason for that many keys is I tried to eliminate using modifiers, which slows me down more than when I have to reach for the designated key, and now that I been using this for over a week, just works better for me.
For example, all F keys are at the left of the... left console, much smaller buttons, just because I dont use them as much as the other keys, convenient, thats all.

I saw you`ve attached a trackball to your KBD, nice. Ever considered using a diferent sensor with teensy and add custom keys  ?

https://www.tindie.com/products/jkicklighter/pmw3360-motion-sensor/ - You can build a trackball around that sensor but you`ll need to flip axis on the firmware because the sensor facing up.

I'd love to do that, viewed that page more than a few times... but I don't have the hours in the day to get my C programming game sharp enough to tackle the task :)

I really quite like QMK, and with layers, I'm doing more mouse based actions than I've ever done. The keyboard+trackball is just wonderful for stuff like CAD, spreadsheets, anything that's a quick mix of typing and mousing. The Ploopy open source trackball apparently someone ported QMK to it, so the integration is generally there, but for now, the dremel is the quickest way to my happiness for now :)

There's lots of split keyboards now with rotary encoders as options... hoping that one day they do similar thing for optional optical tracking support

This is epic! Been following silently for about a year, really happy to see it finally come together. I don't know if you want to bother or will get them re-printed but if you want to level up the keycaps I'd consider filling in the insets with something like black nail polish and then sanding the tops to a smooth finish.

Thanks, oh yes, the nail polish technique, you can see it I`ve done it on the first page and posted pictures with few keys. Other than feels little smoother doesnt really do much as I dont look at the keys while typing>

@nevin - That`d  be awesome, I still have the plastics from when I made the trackball case with much larger ball and bearing for smoother scrolling experience.

not sure about integrating it into QMK, that's a much bigger project than what we're working on.

QMK already has mouse keys (but that's an emulated mouse), and most of the code for the mouse we've been using is for reading/interpreting the input from the  optical sensor, the buttons are secondary/minor programming.

i guess it's something we could look into, but i never thought about combing them as i rely too heavily on a standalone mouse but i see the appeal for an integrated trackball. depending on the controller, space for the programming may be an issue. (some boards don't have enough memory to even support a full install of QMK, ...all the features QMK can do.)

most off-the-shelf keyboards with integrated pointers/trackpads/trackballs have a keyboard and a mouse cable. even though they are in the same housing, they are actually wired and interpreted separately.

currently, we've been using the old teensy (but promicro should be fine too) with the optical sensor iso mentioned to make a custom mouse.

The Teensy 2++ has plenty of head-room, I don't think that it's all that outrageous that if one wants a higher-form-of-mammal that they have to use worthy controllers :)

I'm personally fine with hard-hacking in a usb hub and logitech like I have been doing, as it means I can make a keyboard with a USB 3 card reader, plug drives into the keyboard, etc... the desire for full integration of course is just the fun of making a complete, compact, single piece of hardware that doesn't need a logitech driver (it would also allow fun things like being able to tweak the firmware to do mod conditional things like mod key, then trackball is scrolling... which logitech's take on it isn't super great and is dependent on windows/mac to work (not portable to linux terminal)).

...imagine being in Vim, holding mod, and the trackball whizzing the cursor around... so much fun to be had :)

it's more than modest amounts of awesome, so great... I just adore looking at something that just appears beyond crazy, but in use is just magically correct.

Similar to it wrapping around your hand, I think that keyboards could get similar things with palm and wrist rests that if the keyboard was properly shaped should allow you to use the thing without moving or bumping your palm (even the most ergo of keyboards these days still rely on the flex in your skin somewhere that allows you to nudge your hand forward to reach keys)... trackball playing is just part of this mix for me.

love the forward/back, just not sure how well the sideways action would go... likely make your fingers stronger.

Agreed on the brain reader, the sooner we can just sit there blankly staring at the screen while quietly drooling to ourselves the better...

You can revive dead trackpads from old laptop using arduino, I believe I saw some deskthority threads but I got this one that was all scratched up and battery connector bent, for $7, cant pass that if is an easy mod.

Great work. The whole project is really impressive!

I have also done the same with old laptop trackpads from eBay :) I've had success with lots of different Synaptics devices although it seems impossible to find more than one of any specific model anywhere. I also tried the off-the-shelf Azoteq boards from Mouser with the hope of being able to build several identical devices, but I have not managed to get them to work so far.

Thanks for the trackpad mouser link. You can find similar lot trackpads on eBay - search "lot of trackpad". Also, https://www.azoteq.com/design/software-and-tools/ - they have drivers and arduino code example, is that what you`re missing ?

Thanks, I have tried their drivers and Arduino code but for me the boards never respond correctly to the initialisation step so I can't get any data out of them. So I've shelved that project for now and I'm hacking on trackballs for a while instead :) But I plan to go back to it someday. I love having a trackpad built into a keyboard.

The base is all 3D printed in PETG. The top and bottom parts of each side are separate and clip together. The switches and trackpad are all handwired to a single Pro Micro.

The layout has “mirrored” alphas so the left half is QWERTY but if you hold a modifier it flips to POIUY, etc. (it's really nice being able to type with one hand but I never got above 50WPM). The keys around the trackpad are mouse buttons and modifiers plus Escape, Tab, Enter and Delete along the top (I found I really liked having those near the trackpad).

I'll look at it a little later today.

-Guessing you're just doing a protocol converter?
-Is the original track pad ps2? Adb? Or older serial  rs232?
-or you trying to use the raw components?

Just one point of difference with me. It was epic.  ;)

Did you know that you had been nominated or have you just found out?

I think this competition is not well promoted. Only 18 voting for a community of more than 80,000 members, that seems abnormally weak to me.

Is not promoted because there is nothing to gain from it, why would anyone put any time into messaging the thread creator about the "achievement" ? :)

There should be a differentiation between type of keyboards/devices too, there should be "Well engineered", "RGB bling" and "FK Qwerty".

it would make the thread creator happy, and having happy people post isn't the worst way to keep people excited about contributing to a community site. you should dangle this in front of people at hackaday... getting on the hackaday homepage will put a spring in your step :)
