6. Multiplexer bypass solution still to be tested; if not effective, an alternative solution might need to be found.
9. New prototype hardware including fixes (some already identified) needs to be made. And tested.
10. [Possible final iteration of prototype hardware.]
12. Prototype of thermal solution needs to be made and tested.
13. [Possible iterations of thermal solution.]
14. Thermal solution components must be mass produced.
16. Final tweaks to keymat need to be made and tested.
6, 12, 13, 14, 16 are all done/not necessary
I was shocked and upset to see what I'd written quoted with yet another obstreperous and belligerent post by m@t.
But then I realised that this had happened through the quirk of the forum software that merges consecutive posts!
I'm happy to hear that more things have been ticked off the list already or will be entirely unnecessary.
Seems I missed some things. I hope you won't mind me asking for clarification of some of them.
Re: 6 (and 9 to 10):
In the initial post in this thread [1], EvilDragon said that zmatt had not had an opportunity to complete testing of the multiplexer bypass, but had set aside some time to work on it this weekend (the one that's just finished). So it seems to me that 6 is not quite yet done. Has there been further news on this that I've missed?
Re-reading the post though, my understanding is that, if zmatt doesn't turn up the need for any modifications that can't be tested by jumpering the existing prototype, then there will be no need for another prototype run, and we can go straight to mass production. Which would be very nice news and it could make 9 and 10 disappear.
Re: 12, 13, and 14:
By the "thermal solution" here, I didn't mean the measures that have been taken in the circuit boards themselves, but rather the solution external to the circuit boards. I'm fuzzy on the details, but I had imagined a thermal connection widget between the CPU board and the main board and a large aluminium plate between the CPU board and the case. Was there a post that I missed that said that the design of these had been finalized, and indeed that the parts have already been mass produced? Or do you mean that these parts have been determined to be unnecessary?
Re: 16:
I thought that the purpose of mailing the current prototype keymat around [2] was to form a consensus about whether it is in the Goldilocks zone, of if it is now slightly too soft. Also, wasn't there a very recent tweak to the design of the keymat to resolve the slightly mushy d-pad problem? EvilDragon also mentioned minor modifications to the size of the ABXY keycaps. These three items were what lead me to think that there would be, or that there might be, another keyboard prototype before the final version is mass produced.
