PingJunior: 60% PingMaster build

Hello guys. Some people are very interested in my new PingJunior build, so I decided to start a new topic here.

I have a Pingmaster keyboard that I get from eBay, this keyboard is really awesome, smooth switches and thick doubleshot caps. But it's too big for me so I made a custom pcb to turn it into a 60% case.
I used FR-4 plate so it's pingless, not sure what will happen if you use other metal plates.

My final HHKB layout build:

And answer some questions here:

Do you plan to run a GB or open-source the schematics or something? :)
I don't want to run a GB because price of pcb+plate is about $20, but shipping fee will be more than $30 from China. That's really weird.
So I will put them on TaoBao, maybe find a proxy can save your money.
And this PCB not only support SKCC, but also SKCM/L and Omron B3G-S. Too many holes there and I designed the PCB in a rough way, schematics looks like shit. I will share some footprints and plate files.

Support 1.5, 1, 1.5 on the right of the spacebar would be cool too.
1.5, 1, 1.5 and 1.5, 2.5 can use the same plate.

also, do you notice much of a difference between NOS from tao vs the NOS switches in the pingmaster?
They are pretty much the same. But 1/10 of NOS switches are a little bit sandy, might need lube.
Another thing is I rotate the switches by 90 degrees (like Apple m0110), they could be a bit smoother.

Wow, great work!
Do the Alps stabilizers have enough clearance from the B3G-S switches?

Hell yes, very cool! Would def pick a PCB/plate up if you link them. Standard 60% case compatible?

They are running smoothly, my few keys are overly thick for B3G-S (F, J, Spacebars). Most of alps caps should be fine.

Cases are compatible but SKCC is taller than MX

Good, Tai-Hao caps would fit (except for the spacebar which could use a Cherry plate mount stab)

This is an amazing project! I will be eagerly refreshing for that Taobao link and plate file.

Amazing project, indeed... and it could go quite some way into solving a pet peeve of mine. Allow me to explain before you all think I've gone (again) off the rails.

I really like the pingmaster. But what impedes me from having it as a daily driver is its lack of an F row. I've tried a few workarounds, but none are as comfortable as having the actual F row in its place according to the enhanced layout's design (YMMV). I remember having seen somewhere a dedicated keypad with 15 keys in a single row... I could get one of those and put it on top of the keyboard, but recent experiences with a numpad separate from the main keyboard convinced me that using different switches in one and the other is quite less than ideal (YMMV).

I think the best would be to make a similar keypad/case/PCB as what was described in the above paragraph, but supporting Alps SKCC switches, put on it the switches and caps taken from another pingmaster on it, and then glue/velcro/whatever it on the topside bezel in the desired position. A bit like this (totally sophisticated) illustration:

What do you think? Could something like this be workable?

Maybe something with 10 F keys to the side like a 4704? It will make the keyboard much bigger but it looks very good on the model F. Only problem is that you'll have to use a different set of caps because there is not enough.

If you use SKCC switches to do it, the top row keys will be really tall. How about Cherry low-profile switches?

The idea is to use the same kind of switches... or at least other switches that feel close enough for them not to strike the user out of place (YMMV).

If nothing else, I should try to score one of those 1-row keypads, even if they have some cheap-ass Cherry MX clone, to test out the concept and see how it goes.

I tested the solenoid using a Xwhatsit solenoid driver and it works great. There is enough space for them in the plastic case.
The new version of PCB will be done very soon.

You DO realize that once you've gotten a fully working version of the SKCC PCB, you'll be swamped with requests for versions in other (larger and smaller) layouts, right?

Write me up for a TKL and a 75%, please. :mrgreen: :mrgreen: :mrgreen:

Oof that's a rare board to find. Let alone the model with the key caps you got.

Do the Omrons work int the SKCC plate? Or do they need a different one?

They are different, SKCC plate hole size is 14mm but Omron is 13.5mm.

DrClick, I'm about to buy one of these on TaoBao but am curious about one thing. Do I need to buy some microcontroller or is it included on the PCB? The PCB seems too cheap to have all the parts needed but maybe my expectations are wrong.
