Keyboard That folds

The Fold Board!

This is a super cool keyboard that I am making

It folds!

and fits nicely in a bag

Total Time spent: 38

13th of June

Did the entire pcb in one day.

Since this is technically a split board, I would normally have needed 2 micro controllers and ttrs. But I aint doing allat.

My design uses one microcontroller and uses 16 wires to connect the 2 halves and bring the right side matrix to the left.

The wires can also function as the way the 2 boards are held together(joke there will be more supports)

I still need to add silkscreen so its not technically done but functionality is done.

Anyways explaining the keyboard.

Its a normal keyboard thats about 75%ish idk it has 84 keys.

it folds and has 16 wires to connect it together

pcb

Hours spent: 4

15th of June

Started work on the case and trying to guage out how I am going to figure out how to have the 2 halves connect and how I want it to look

cad

Got this so far, spent a few hours on it and looks kinda nice. might do some more work onto it before moving to the fold

Hours spent: 2

17-20th June

Did little bits and bobs of work, not too much but small touches on the pcb, and cad whereever i got time. total time across these days is like 2 hours max

21st of June

I am actually stupid.

bah

can you spot the problem here?

thats right

i put 4 rows instead of 5

time to start from scratch again. YAAYAYAYAYA

anyways did lots of work today on my case, went through a few designs, got some of the nitty gritty down, also did a few touches on the pcb but nothing significant.

Time spent: 4 hours

23rd of June

Today I went through some designs for the bridge of the 2 halves.

boo

This is what I was originally going for but that doesn't really fit well with the rest of the model. so then I tried a different one.

This one is more straightforward and allows me to make it a bit slimmer. idk if i mentioned this before but i want to be able to push these 2 halves together when it lays on a table. to the bridge needs to be able to fit in the case.

In the end I just settled for a completely flat bridge. I had the curve before because it would go around the top plate but now I had shortened the pcb and plate in order to give the bridge room to sit.

Time Spent: 5 hours

29th of June

Okay time to start grinding ts.

I polished up on the case and started adding final details with usb port placement and added the proper placements for keycaps and added my logo onto it.

Time spent: 2 hours

30th of June

Firmware time!

I reinstalled mac and turns out my mac is too old to install qmk so I cant compile code and have to copy paste previous firmware folders and then change the pins and keymaps. Also github copilot is soooooooo good. i love it i love it i love it

It saved me soooooo much time with firmware writing.

it does all the zombie work for you

Sure it has a few hiccups but its still amazing

Time spent: 2 hours

1st of June

I just realised that I need to have some sort of thing to hold it together.

So I made a bit that uses a rubber band to hold

djf

Looks like that for now. might change if it doesnt work

Then I made my BOM by scouring for a bit on aliexpress but most of the stuff was easy to find since i have made a board before and I just used the same places.

Then the readme. That was nice. I think it looks nice, better than my last one at least

Time spent 4 hours

2nd of June

Submitted :D

17th of July

Came back from underity and am pooped. the parts arrived a bit back just after I left. anyways i will update

18th of July

Soldered the pcb and printed the case. Kinda messed up the screw holes so need to fix that

hours spent: 5

20th of July

Finished the base and now I need to make Keycaps. but will put it off a bit to finish my other project

hours spent: 2

2nd Of August

Made half the keycaps and it took me so long to line everything up :sob:

But they didnt even fit :( It fits enough to stay on but not enough to go all the way down on the stem. going to have to add more tolerance to it.

anyways that sucks but meh. imma take a break for a bit cuz im not bothered rn

Time spent: 2 hours

13th of August

My printer had a poop of death :sob:

Im cooked

21st of august

Replaced the centre wires with longer ones because they kept snapping. also made paper keycaps because I cant do printed ones. I just stuck them on with blu tack.

Anyways done :)
