I recorded two separate prototype soldering, one with hot air only and with iron only.

watching your video(s) right now while i'm working :)

Same here, but more like fast forward style  ;D

So,
My oscilloscope shows me that my crystal is oscillating at 50khz as well as 16mhz.  The amplitude of the 50khz is greater than the other by quite a margin.

That's bad.

Also, I borrowed a logic analyzer with built-in protocol decoder and the host attempts to sync but the atmega never responds.

Replacement discretes should arrive tomorrow.  Will post again when I'm working.

A little teaser of the GUI:
(Attachment Link)

Got teased here  :D

I also have 2 questions:

1. Will it be possible to, for exemple, press the capslock to go to a specific layer on the first press, stay on that layer, and come back to the original layer on the second capslock keypress?

2. What do you use for coding language? Will you share the code or make it open source or something like that at some point?

Thx a lot for doing this by the way!!!

Not everyone... Soarer's converter is still closed, and I think there may be a couple others that have very limited exposure that have also chosen not to release.  Several people host on github tho.

I replaced C1, C2, C3, C7, R5 and the Crystal.  It immediately fired up.  I was able to type a few characters so the firmware is cool too.

My 17" LCD for my Propeller Pi laptop is on its way.  Once that's measured and a frame built for it I can then find a small, maybe 7" VGA or Composite Video LCD for the propeller.  Then I can machine and build the frame to support the keyboard.

I'm stoked!

If it was indeed it was a defective crystal, I'm just glad that one defective part whet to you haha. If it was one of the 12 that I had to solder, I wouldn't have known what to do. At least you have an oscilloscope to test it. I only have a DMM. I'm glad you got it all figured out.

New switch hole design:

   

#2 - this is the design I have on the new phantom plates and the the TKL plates GB I ran.
#3 - some switches on this PCB needs to be rotated 90, so this is just basically a 90 rotation of #2
#1 - a more crazy design that can be put on every switch that allows rotation in any direction


All these are designed to allow opening of the switches without desoldering. Most switches on the GH60 only needs #2, and some needs it to be rotated like #3. If all the switch holes were to be uniform, then #1 design allows any mounting orientation. This would be good for future PCBs to be designed without needing a specific plate to tailor to the specific PCB. If quotes are not much more for the extra details of the #1 design, then probably that design would be best. Comments/opinions before I start drawing up the different layouts?

Have any one else consider underplate? I make some G80 mod like this with MY switch plate. Only need cut to dimension along with thin rubber mat and a few holes to allow the mounting bolts to pass through. Would give it a more sturdy feeling removing flex when use stock plastic case but without taking away from the other pros of pcb mount feel. Only would need one design too, very easy.

#1 would't work because the clip that keeps the switch in place is exactly where the rotated gaps are.

#2 and #3 give the switch less grip than holes with 2 gaps on each side.

I would recommend conventional holes with the conventional mod for top removal.

The ideal situation would also be where the plate is connected to the case, and not the PCB. That means small holes for the screws, not holes to reach for the screws that are actually on the pcb. For this board however that would probably not be feasible.

#2 and #3 have all 4 corners and the whole top and bottom to lock in the switch. It's not moving anywhere. These can only be mounted in 2 directions though. I have 40 TKL plates with this design.

#1 would work. It's an overlay of #2 and #3, and I specified the middle tabs to be just long enough so top and bottom of the switch can lock no matter what orientation you mount it. All 4 corners also hold the from any movement.


I'm not sure you fully understand how those hole cutouts work. What exactly do you have in mind for "conventional" holes?

It's a trade-off between a situation where the key barely locks and is barely prevented from moving on one hand, and where the key is firmly locked into place with maximum support on all sides. If the lasercutting (or worse cnc) screws up a corner, the key is only supported by pcb and the plate is (for that key) useless. If you're using pcb mount keys you have some slack, but plate mounted keys leave no room for error.

Maybe you should run a prototype.

I like #1 - Even if the key doesn't lock into the plate, size it correctly and there will be enough friction to keep it in there very tightly.

With tinkering with The_Beast's Poker Plate with MX I found MX has different width at its corner.
My cheap caliper says horizontal width is 13.80mm while 12.95mm at vertical.
This difference causes kind of wiggle when you place MX at 90deg or 270deg rotation in Poker Plate. Unfortunately Poker Plate has a bit too short width of middle tabs to hold at firm part of bottom case not only at lock spring.
Not to mention, Poker Plate works well with proper rotation of switch. This is not a complain about Poker Plate.

Though 4 corners of #1 is not enough to hold firmly, with proper middle tabs #1 would work.


#2 and #3 have all 4 corners and the whole top and bottom to lock in the switch. It's not moving anywhere. These can only be mounted in 2 directions though. I have 40 TKL plates with this design.

I know exactly where you measured it, and those are the wrong places. Move it up a tad. My digital caliper says 13.97mm, which is pretty much spot on with cherry's specs of 14.0mm at those areas. Also, according to the cherry's dimensions, the switch is a perfect square at the areas held in by the plate. Each side of the hole is 0.55" (14mm).

The poker plate you played around with have the exact same switch cutouts as the original phantom. You can rotate the switch 90° and it will still hold it in place fine, but you'll lose option to open up the switch. If you fully mount it where it locks down, it's sturdy and won't move. Here you can see the plate cutout that cherry specified, which is how the phantom switch and stabilizer holes were derived:

I've looked at both laser cutting and waterjet to cut the holes. Water jet won't be able to do fine details, but laser cutting has good enough tolerances to cut the plates. The 4 corners as well as the 4 center tabs are actually touching the switch to hold it in place.

I've already prototyped and made a stack of TKL plates with hole design #2/3. I'll promise you #1 hole design will be fine :) . It's not really a question of whether it will work or not, but which design is preferred for these new plates.

hasu, I think you were measuring at the wrong point, with my cheap calipers I got 13.57mm x 13.70mm :x

On the sides of the housing with clips


On the sides without the clips


I also replicated your result of 12.70mm

On the side without the clips, measured at a different point


The 12.70mm is measured from the "bottom" of the switch, while the 13.70 is measured from where the plate comes in contact with the housing, as shown below.

Where I measured 13.70mm


As long as you make that middle portion on #1 around 6.48mm, it should be able to both hold the switch in the vertical and the horizontal :)

The length of the 13.70mm portion of the switch, that won't interfere with the clips on the housing

My point is that four corners doesn't touch switch case perfectly and we need proper middle tabs to get better support for switch in #1 design.
You'll see small gap at bottom corner and switch case in photos below. On left side large gap is by design, of course.
On the other hand this gap is never problem in #2, #3 and Poker plate with normal rotation switch.

Left bottom corner of switch with normal rotation.


with 90deg rotation. Poker Plate's tab is a bit short and can't support rotated switch firmly.


Normal and rotated mount side by side.


[EDIT] replaced photos with a bit better one and added some photos below.

Note that corners can't hold switch sturdily in #1 design as this photo indicates.
Never mind if you already found this yourself. I just wanted to let you guys know this.

This short tab holds switch only at part of plate lock spring. This causes horizontal wiggle.
If it is a bit longer it will hold sturdily at firm part of switch case.


I think we can have a bit longer tab than Poker Plate without interfering switch open.

You’re basing all your fittings and pictures on the poker/phantom plate design. But you can’t really make the assumption that these new hole design is exactly the same as the poker/phantom plate, which they’re not. The corner notches on my design is actually a tad bigger, combined with the whole top and bottom edges, that side flap was not needed. Refer to THIS post.




The switch holes here are the holes from Figure A. Those corners are as long as possible. If they’re any longer, you won’t be able to open the switch. I do know what you mean by that extra tiny gap next to the corner though, but that gap doesn’t affect anything. The corner alone holds the switches firmly, but the two top and bottom sides also add support. The switch can’t be moved at all. This obviously won’t work if you rotate the switch 90degrees, because that plastic lock spring has nothing to clamp on, and the switch tabs can’t be opened. This is why Fig. B is necessary for a rotated switch, which is basically Fig. A, just rotated 90degrees.



Now if you look at Fig. C, it's just an overlap of A and B, and that's why I know the final design will work. The corners as well as the solid blue line at the center of each side hold the switch in place. That solid blue line is actually touching the switch to clamp it down, and it's just long enough to still allow you to open up the switch tabs. If you darkened all the important lines and got rid of all the reference lines from Fig C, then you get Figure D, which is the final design of the switch hole that will allow: 1) any rotation orientation of the switch, 2) opening of the switch, and 3) clamp the switch in place and for the top/bottom plastic clips to lock.


Man this is pretty hard to explain and to point out which parts I'm referring to, but hopefully it's coherent. lol does anyone actually understand me?

I didn't say your design won't work and I think I understand your design intention.

In design D four corner notches can hold right/left side of switch but not top/bottom side,
so tabs are important in this design, right?
BTW, Poker plate seems to has same size notches as yours in the photo.

My concern is only width of four middle tabs. I found shorter width tab won't hold switch firmly, because it touch only at plastic clip part.

I think middle tab should be long enough to reach solid part of switch case. maybe 6.00mm or so? as far as it doesn't interfere opening switch.

Yeah, those tabs in the middle of every side is absolutely necessary in the design so that the two plastic locking clips have something to clamp on. I specified the width of those tabs to be 5.10mm. You really only need 4.25mm for them to properly work. I took tolerance into account, so 6.00mm is probably too close to the switch clips that allow opening of the switches, 5.10mm is a good intermediate.

Anyways, I'll stop ranting about this. I'll move this discussion to the main thread if there is anything else to say since this thread is specifically for actual testing of prototypes.

I'll also stop posting about this :) Sorry for derail, guys.

Hmm, looks like I couldn't convey what I want to say. Or I'm completely confusing about this.
5.10mm is almost same as Poker's size.
I still think switch will wiggle along top/bottom direction with that width tab.

Can someone give me the exact size of the PCB (L x W x H) and where the center of the USB port is?

285mm x 94mm, USB port's center is 17.57mm from the left.

The vertical dimension may change slightly, because the stabilizer holes are too close to the edges now.

Thanks, how thick is the PCB and how thick is the PCB w/ the USB?
