[IC] Programmable drop-in G80-1800 PCB
« on: Thu, 02 November 2017, 14:46:20 »
Hey,

I've been working on this project for a little bit, since I got a $27 G80-18xx on ebay as have a few other community members.

The PCB is almost done on KiCad, I just need to finish up the traces. It'll fit the G80-1800 case for sure, because I printed it out 1:1 and laid it over the original PCB to check the mount holes.

Layout:


Features:
1. QMK firmware -if anyone has experience with bootmapper client maybe that too
2. atmega32u4 support (V2 will hopefully have atxmega32a4u once I can figure out how to port it to QMK, or start on my own firmware)
3. No in-switch LED (I'll add the in-switch indicators though, I think)
4. Common layouts (above)
5. Both a mini USB port and pads to hand-solder a cable to the PCB
6. Hybrid diode footprint, allowing either through hole or SMD microMELF diodes.

A few things I'd need:
1. confirm that the G81 case has the same mounts as the G80
2. Dolch PAC indicator LED positions
3. probably something else.

I have ~10 people who've expressed interest in helping cover prototyping costs in exchange for a working PCB. Once I have the PCB finalized I can get pricing to them and get the first prototypes going. I'll be doing the SMD soldering, at least for the prototypes.

Thank ya

Interesting. I'd suggest a split backspace option too.

Sorry i didnt reply to this earlier - I'll look into it, but i think i didn't add it before because it'd add an extra column. i'll see what i can do though.

Split it on two different rows. You can make half of the backspace as a F13, since you have room on that row. I use this trick and it works.

Depending on how much shipping to EU is I'd love to help with this! Have a G80 in my rotation anyway and would love to update the layout and get some rollover :D 
I have an ISO board if that helps.

Hey, quick update

Someone (pwner) was gracious enough to send me a G81-1800 case, and it's the same as the G80-1800 case.

I ordered the proto PCBs, microcontrollers, and other stuff I need tonight. Should get to me in like, 2 weeks max?

Glad you split the backspace, I appreciate that.
I guess the numpad enter could be split as well, for the sake of it.

Would you mind posting the schematic? I'm really curious about a couple of things.

Not sure. it's currently designed to fit the G80/81-1800 case holes/mounts, not sure how the TX-1800 deals with mounting.

If I remember correctly, the Leeku PCB fits G80 cases, so that might mean this pcb would fit a tx1800 case. I can try it out once I get mine if we don't have an answer before then.

Is this the appropriate thread to ask about case options? I'm wondering what colours and finished will be available and info on MOQs for colours.

Got the protos in today.





Thereís two small issues Iíve found:

  • The mount holes are slightly too large, this gives a tiny bit of wobble (up-down movement) to the board. Iíll fix this on the ď1.0Ē version by switching to ľĒ holes from 6.3mm. Iím going to explore ways to mount it a bit more securely (tape, etc). Someone could also use 2 or 3 screws to screw the board into the G80/81 cases, since thereís a few holes for that. Iíll figure out what size those threads on the case are.
  • I used a through hole footprint for the 6x6mm reset switch, instead of an SMD one.. I ordered SMD 6x6mm switches. Iíve already ordered through hole 6x6 switches from eBay, I should have those in 2ish weeks. Worst case they may delay me shipping the boards a small bit, but theyíll be super easy to solder on once I have em so I donít see it being a big issue.

Consider adding a breakout for the USB so to solder a cable. Not everyone is fond on drilling holes into their rare Goupil cases.

EDIT: Looks like the USB breakout is above the F12 key.

BTW, you have two F2 and two F6 on your silkscreen.

Very interesting. Since the case of the g80-1800 isn't very solid, I think that many would be happy to purchase some sort of laser cut rubber mats pads. This mat will be placed inside the case to reduce the wobble of the pcb.

The PCB should be very thick, to make the typing experience more enjoyable.

Could the PCB include Holtite Sockets For Switches, to allow hot swapping, and installation  of the switches without soldering?

Lol jeez, true again. I copy/pasted them and manually edited them, ans I was probably tired when I was doing these ones that're wrong. Thanks so much!

Currently the PCB is the standard 1.6mm. I could look into doing a 2 or 2.4mm thick one, if it'd be desirable by the community, for future versions. Looks like the thicker they are the more expensive they are (duh), but I'd be cool with offering both a standard thickness and a thicker one for a little bit more (like $2-3 more)

 A mat is a good idea. I learned that putting some heatshrink on the two large locators in the case helps with wobble a lot too.

I don't have Holtites and I don't think I'll personally supply them, but you should be able to put them in yourself if you'd want to.

Hey I'm dumb

Quoted from the email I just sent to the GB partitipants/proto helpers

Quote
Hey all. Another quick update, thereís good news and bad news.

Bad news first: Iím an idiot. I did not set up the switch matrix correctly in duplex and now every two switches are tied together. My mistake. As Iíll say below, I have to re-order the PCBs once I fix them, so everything will be delayed about a week. This isnít horrible as Iím waiting for a few components to come in anyway (2.4k resistors, other small caps). I aim to get everything shipped out to you/the proxies the week before/after Christmas.

Good news: I decided to return the stuff I bought on black Friday for myself in order to order new PCBs at no cost to any of you. Iím going to fix the matrix design and adjust the small things that were wrong with the first batch then order the new ones ASAP. They will still have a black solder mask finish with white silkscreen. It will be a quick fix and Iíll triple check things again (along with passing the schematics to a few others once again) to ensure that everything will be fine.

Things Iím fixing/adding/changing:
ē   Switch matrix
ē   Small silkscreen issues (2x F2 and F6, and 10 instead of 0)
ē   SMD reset switch
ē   Bootloader flashing pins (thanks Lief!)
ē   Resizing the large mount holes to better fit the locating nubs
ē   Adjust the SMD/through hole combo diode footprint to have less pad exposed


As always if you have any questions please drop me a line! Iím truly sorry about the delay.

Thanks.
Josh

I just received my PCB from EasyEDA and 1.45mm through-holes for the switches is the perfect size for MX holtites.
I've come to view humanity as predominantly monkey business.

Thanks! The footprints I use have a 1.5mm hole. Think that'd be too big, or would it still fit well? Mine are modified from The Keebrary which is pretty widely used.

My mistake, I misinterpreted what you were saying earlier about PCB thickness for the through-hole size. The tester PCB I received from another user only had 1.45mm, 1.4mm and 1.47mm holes (which probably got rounded to the nearest .05mm anyway) and I played it safe by picking 1.45mm.

There are holtites on my VE.A, Leeku 1800 (wish I saw this earlier), and custom PCB. Using my digital calipers, the final size of the holes on the Leeku and custom PCB are 1.51-1.53mm. On the VE.A, final size is closer to 1.45ish mm and the holtites were noticeably harder to press fit without lifting pads. The final size of the holes on my old ZZ96 PCB were right around 1.60mm and holtites fell through. It might work, but with different tolerances between manufacturing houses I cannot say anything with full confidence so take this information as you will.

After writing this I have realized that I have done everything but answer your question. Hope this helped!

Seems like 1.5 should be good then. It's 1.4985 IIRC to be exact, which is only .0015mm difference so it doesn't really matter lol. But yeah I assume these should work well with holtites based on your measurements. I don't use them anyway, but someone might :p
