The copper wire technique is absolutely brilliant. Adding heat shrink to bare wire is so so so much better than stripping out a bunch of tiny segments. I wish I could like this video twice.

For a quick explanation of of the dfu mode it’s basically a mode that let’s you access the bootloader (the place where you flash firmware) different MCUs have different bootloaders and different bootloaders have different ways to enter them (so dfu the board) and QMK has too know which you are using to enter it

It's great you're doing this - even rudimentary info makes the field more inclusive. 👏 This wasn't as clear as I'd hoped since there's a bunch of stuff glossed over, versus taught. FYI, it's really hard to follow along on the code when you can't see the text because you're viewing the video on a phone - it's like maybe 1/8 of the screen. I'll be checking to see if you've got still shots of the wiring, the code, etc. so I can figure it out with the video transcript as a loose reference. 👍 I'd love if non 3d printer options & specs were available, too, because most of us just don't have that $$$ equipment, or access to somebody else's.

@joe_scotto
@joe_scotto Рік тому
My suggestions would be theee things: 1. Make sure the cable you’re using supports data. Not all cables do so try a different cable if the current one is not working. 2. It’s possible you fried the pro micro, I’ve done this to many over the years. If QMK toolbox isn’t detecting it and you changed the cable, that’s the most common other issue from my experience. 3. It is also possible that QMK Toolbox is just being buggy. You can try running the same command but instead of “compile” change it to “flash” which should then allow you to flash the pro micro from the command line.

use decoders, like 2 x 74hc138 for the column outputs and a shift register like 74hc165 for the row inputs. This gives you a 16 x 8 = 128 matrix with only 7 wires: 4 wires for the decoders, 3 wires for the shift register -> reset, clock and data input. If that is not enough add another shift register with no extra wires and get a 16 x 16 = 256 matrix.

Yup, what you’re looking for is a “macro” which allows you to basically program the key to do anything you want. You can program the board to show caps or num lock status but it can’t get info from the computer so no volume or mute status.

Thanks for sharing this and your files. I just made this over the weekend and am fairly inexperienced in coding etc but was able to figure out what applications to download (VS code, QMK Toolkit) and if the directory for the firmware wasn't found while at the cd step, lookup how to link the appropriate drive. One thing I noticed (unless I messed up) is that the wiring to the pro micro around 20:20 in the video seemed off as I was getting 1,4,7 etc.. in my top row rather than 1,2,3. Wasnt a big deal and instead of re-soldering the board I just updated the keymap and reflashed the pro micro and problem solved. Any suggestions on good shortcuts to program into the macropad? Thanks again for sharing as it makes me want to design my own number pad in fusion360.
@joe_scotto
@joe_scotto Рік тому
Glad you could build it :) As for shortcuts, really anything you would want. I set mine up as a numpad where if you press 1 and 2 at the same time it fires 0 since there aren't 10 keys on it but then the rest is just the standard 1-9. Media keys are very common, emoji shortcuts, or have buttons launch specific apps.

You can 'encode' the outputs of some of the row or column lines, and then add a decoder chip. The 74HC138 will decode 3 lines into 8. This gives you an extra 5 IO lines. Use two of these chips to encode 4 lines into 16. This gives you 12 extra IO lines. Some changes will be needed to the software, but that isn't rocket science.

@Joe Scotto Can i use a Pi Pico instead of a Pro micro for this build?
@joe_scotto
@joe_scotto Рік тому
I don’t think it would fit in the macropad but QMK does seem to support the Pico so I don’t see why not.

Can I use zmk instead of qmk and how do I flash firmware for the Pro Micro ? Thanks you

ZMK doesn’t run in a Pro Micro, it’s incompatible with the chip.

@joe_scotto does the diameter of the copper wire matter that much, you used 16 gauge (1.3mm) but I can only find 18 gauge (1mm). Should I be fine using it?
@joe_scotto
@joe_scotto 4 місяці тому
Anything from 14-18g is what I use but it really doesn’t matter. You could use even smaller but I wouldn’t go larger than 14g.

@@joe_scotto thanks a lot, also how are you securing the metal standoffs into the case, is it just hot glued to the case floor above the screw holes?

@@chimage532 The standoffs are just screwed in, they have holes on each side.

Can we just flash the micro controller using the kb firmware builder??

If you build a handwired version of one of the supported boards within the online tool it should work. But, if you're building one completely from scratch, it won't be in the tool.

Hey there, great video. Have been bashing my head trying to figure this out for so long since QMK is so insanely un-friendly to non CS professionals. I am getting thrown errors about MATRIX_ROW_PINS and have no idea what its supposed to mean. I am making a 1x5 keyboard. Is this below not how it should be looking? Am extremely confused and so far youre the only person whos made me get this far lol {"matrix": [0, 0], "x": 0, "y": 0}, {"matrix": [0, 1], "x": 1, "y": 0}, {"matrix": [0, 2], "x": 2, "y": 0}, {"matrix": [0, 3], "x": 3, "y": 0}, {"matrix": [0, 4], "x": 4, "y": 0}
