Thanks for your input! Yes, using two chips is probably not the best idea. For instance kile used a single chip that did everything in his wireless version of PJE's OneHand: https://deskthority.net/workshop-f7/onehand-20-keyboard-t6617-180.html The nRF51822 chip (low power wireless, Cortex M0 core) ...

Just make sure they're aware of that BT controller's abysmal battery life. You're not the only one who complained about that anyway. There are perfectly good reasons to want another BT controller for the HHKB, but it won't appear magically if someone who wants it doesn't give the first impulse :) Mo...

I'd rather open a thread in the workshop and call for people to come and contribute, like how matt3o did for the Elf controller. Surely a BT HHKB controller would be a little more complex, but I'm sure the project would gather interest.Muirium wrote: ↑I'll just sit here and wait for the unicorn to come find me…

I was wondering the same, then I realized I didn't even comment on your last message about requirements. So: +++ C (2.54 mm spacing for pads) is the most important, because 2.54 mm headers are cheap, ubiquitous and easy to solder. It makes little sense to design a controller for everyone to use if t...

So, did he gather money and not then place the GB order? There are sometimes good reasons for getting chaotic and even going dark… for a while. If Ivan's having domestic problems, I can sympathize. I mean, right now I've got a few boxes of GB stuff I need to ship out, waiting back at home, all thro...

IIRC he had been stating for some time that he was organizing those GBs in his spare time and that he would stop at some point, and even before he disappeared he sounded a bit jaded about what he was doing. As for whether the scam was intentional, no one can know. It's entirely possible that those l...

I received my keycaps without any problems, so I think comments like that are uncalled for. Sorry if that sounds harsh, but this is unfortunately what the current situation looks like. People who bought his PBT Dark or Miami Nights keycaps have virtually no hope of getting either the product or bei...

I have mixed feelings about USB-C. On the one hand, it's the latest standard, cables and connectors are now available for relatively cheap, and it's reversible. On the other hand, it makes the controller more expensive, takes more real estate on the board (wider & taller as Moz points out), and we d...

Keep in mind that proportions are way off in this drawing. If the micro USB connector was 3 mm high overall (which is the standard height), the PCB shown here would be 0.6mm thick. We'd have to check the datasheet of the particular USB connector we would use, but with a standard PCB (1.6 mm thick) i...

Define "last long" :) I've been plugging and unplugging my board daily for two years and I can't see its USB connector becoming a problem anytime soon. And yet it's almost the worst kind you could think of, surface-mount mini USB, with no anchor in any kind in the PCB. As long as the user does not a...

Issue I see with mid mounted connector is that you won't be able to mount the controller flat on the main keyboard PCB. Yeah, it might stick out a bit from the bottom (not by much though, probably just a few tenths of a millimeter) so the controller will be slightly slanted, but the overall height ...

The big question is, how much clearance would be enough? Would 36.83 mm be fine (that's merely .6mm more space on each side), or do you think the board should be even more shrinked? More shrinkage = less available pads when mounted over switches, and more rework from mohitgarg :P A board with a micr...

I checked for space, there is about 39 something space available according to the spec, in any case, it should fit fine because the stab is mounted on the top side of PCB . That's a valid point. Just in case, here is the difference: http://reho.st/self/bc6dc6982c7d24052539ce8b9d5608f4ade8ce02.png S...

The problem if we add a numpad this way is that if you cut the last column of the main block to get a 60%, you also cut the numpad. So it's either 65% + numpad or 60% alone. But we could add pads on the right side of the PCB (between the last two columns) so that people could wire a separate numpad ...

I think that uniform backlight under all keys would be sufficient, the ability to adjust the intensity via a key combination seems more useful to me than individually addressable LEDs. Something like 5 intensity levels would be nice, but I guess that could be changed in the firmware if needed. RGB L...

The idea of a larger PCB with breakout sections is interesting, but they would need to be easy enough to remove (without sawing — PCB dust is a health hazard, so breaking is better) while remaining strong enough when attached. Cost-wise, I'm not sure whether this would be preferrable to several fixe...

It just hit me that what you see is not actually copper, but ENIG plating. Depending on what finish you choose (ENIG or HASL) and how the fab assembles the board, it may turn... grey-ish instead, because during the assembly process all exposed copper is usually covered in solder. Unless there a spec...
