Hello everyone, Rico here.

I would like to let you know am slowly working on adding support for released boards for the Leyden Jar controller.
For this I used the incredible work that NathanA did for its XWhatsIt Vial firmware work.
Adding a new keyboard is not a fully automated process but is fast ...

MT3 3227 looks to be a very good fit and you can fill the F13-F24 with the extra kit.

It is in stock and rather cheap.

Thank you idollar !

Looks to be good
There is just one little modification to be done on top of yours to have both Windows and Linux compiling
Will do that soon!

Great, thank you !!!

Thank you Ellipse!

To be honest the biggest help for a Linux noob like me would be someone to look at the Linux build of the Leyden Jar diagnostic Tool.

This proposal for solenoid and UART at the same time is perfectly legit.
I see that someone carefully studied the Leyden Jar schematics and read ...

Hello everyone, this is Rico!

With Ellipse acknowledgment please let me share the current status and future work of the Leyden Jar controller here.

First I'd like to apologize for my lack of presence in this forum; internet is a time killer and I try as much as possible to optimize my free time ...

This is looking great !

Just had a bird eye view of this thread and I am impressed!

This is a really cool project that you did, I didn't know this feat could be possible to do.

Congrats !

In VIA: go to the "Special" section, and find the "Any" key. Then it will let you type in raw key code hex values.
In Vial: just double-click the key, and type in the hex value.

So nothing 'magical' for those special QMK codes, too bad.

Think the Leyden Jar is mostly setup for VIAL instead of QMK/VIA if my understanding is right.


You are totally right!
I feel like VIAL is the best solution for XWhatsit and Leyden Jar controllers.
VIAL automatically detect your keyboard while for VIA you need to go to the hassle to add ...

I could half test NathanA work.
It is not an extensive test as my XWhatsit controller is currently desoldered (I have a Leyden Jar Rev 3 controller soldered on my F77).

Installed new_model_f-allpads-vial_r4b1.zip
Thanks to the provided .bat files the flashing procedure is pretty straightforward ...

Hello sedevidi

Could you elaborate a bit on the current status of this promising project, please?

Please let me give a quick status of this project.

This is the first revision of Leyden Jar PCB, a RP2040 based controller aimed to work with Brand New F77/F62 boards and in the future Brand New ...

It has to be noted that Xwhatsit’s PCBs rely on 5V USB rail as a voltage reference.
This is not only used to drive the columns but is also used as a voltage reference for the DAC that is setting the activation threshold.
So any drifting or fluctuations over time of this 5V rail will definitely have ...

I'd need 4 comparator chips to do that instead of 2, but yes in theory it could be faster.
For now I have 640us taken to scan the matrix (can probably be faster later on), but I don't change the DAC value in between.

The PCB does have 16 columns and 8 rows and I am pulsing the columns, i'll see how it works as is for the moment.
And I have yet to see if changing the DAC value during the scanning is needed in my case.

Glad to hear that you have consistent results with the different boards you have, this is a ...

Thank you Arkku for this very detailed answer !

That's funny because I had already found your QMK repository and already started to dive in the source code :P
Thank you for confirming the util directory contains the Pandrew utility I was looking for.

I see that you and Pandrew went to great ...

Thank you very much, I'll have a look !

Hello fellow keyboard enthusiasts.

I am happy to be a new member of Deskthority forum!

I would like to talk about my current project here as it may interest some members of this community.
A few months ago I received my Brand New F77 Model F keyboard.
This board is absolutely stunning in every way ...
