2022.04.16 Update:

Apologies for the long delay in terms of updates.

I picked up some other projects after I had some issues regarding ordering the PCBs and supply shortage (ATMega), and moves away from this for several months.  However, this project has been in the back of my mind since, and I've grown frustrated of waiting.

So, I am pleased to say that the PCBS have now been ordered (with the respective stencils) and should be arriving in the coming weeks.  From now, I will be focusing on acquiring the board components, and getting the needed hardware for programming the ATmega chips.

However, regarding the ATmegas specifically, I'll have to search alternate sources for these chips, at least enough to build some prototypes.  Originally, I've been looking to purchase all of my components from Mouser, however they estimate to have these chips back in stock in February of 2023.

Which, taking into account the seemingly continuous meltdown of our global infrastructure; is understandable yet quite frustrating.

So, if I can source these chips, expect more updates soon, I expect to begin building the boards as soon as the supplies are in, and begin creating the firmware for the board.

If not. . .  I'll have to pivot to the software side of things until the physical components can be located.

(Worst case, maybe eBay will come in clutch).
