Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Help with pin headers (lemm.ee)

Using previous advice here I managed to assemble a piantor and soldered the microcontroller on the pcb directly and I have to say that for a complete beginner that was very challenging.

I've gotten 5 pairs of PCBs and I kind of destroyed one pair but I am still trying to assemble at least another keyboard so I have a backup as I reckon it would take me a few days to be able to be proficient again on a non ortholinear keyboard now.

So I decided to try to use the female pin headers to be able to remove the microcontroller if I ever need to in case it dies or something of the sort.

I had the regular pin headers already and I know I can remove the pins from the white strip so I was going to solder them into the pcb while attached to the female and cut the extra length they'd have.

I got this specific female ones from Aliexpress https://www.aliexpress.com/item/1005005053790061.html I got the ones named "1x40P Female Tin"

When they arrived however, I ended up noticing that the regular pin headers I have do not fit the female ones. I have no idea what to search for to buy just the pins and what dimensions I'd need to get them, can anyone please advise me on what's the name of the loose pins and which ones should I buy please.

Thanks in advance, thanks to this community I have a working kb now :)

Those are for the IC chips' pins, not for Dupont headers. The corresponding female connectors for those are these. Alternatively you'll have to use the IDC pin headers.___

You did your link backwards. The text is the url and the url is set to "these".

[–] [email protected] 1 points 4 months ago

Sorry and thanks. I always get those messed up for whatever reason.

just search for "needle connector" on aliexpress.

but you could also use cut off legs from diodes or simmilar.

I think I found some. They all come with the plastic part, are the pins removable like regular pin headers or I’d have 2 plastic “strips” when I have them plugged in?

Regarding the diode legs. Aren’t them too flimsy. If I remove the microcontroller would it be easy to plug it back or they’ll bend too easily. I think I have some diodes laying around I could use

[–] [email protected] 2 points 4 months ago

I've found diode leads are too thin and fall out or sometimes fall to make contact. You need the matching pins since the have a larger pin diameter

i'm still waiting for parts, but my plan was to do it that way: https://keycapsss.com/help/lily58l/buildguide_en#install-pro-micro-with-sockets

but i'm not planing to unplug the arduino unless it's broken. even though, i think at that length, they might be "stable" enough to be replugged.

the plastic part should be removeable. but then you might have to cut the pins.

The sockets look similar to Mill-Max Headers & Sockets. They could be bought at various electronic component outlets. However, the original MillMax are a bit expensive.

~~“Machined pin 0.1 headers” are the fancy kind.~~ Just get the males from the same listing, I’ve never seen them sold loose.

[–] [email protected] 1 points 4 months ago (1 children)

So, which one from that listing should I buy? They look all like regular male ones

[–] [email protected] 2 points 4 months ago

1x40P Male L-11.96mm or the next one should work.
