The official guide says: There is space for a 15 x 22 x 7.5 mm battery. I don't have a paquimeter here, but of helps my battery is 5mm X 15mm X 22mm 140mha, I bought in a local shop here in Brazil. produto.mercadolivre.com.br/MLB-3132175293-bateria-140-mah-37v-2-fios-5mm-x-15mm-x-22mm-501522-_JM I think you can find some in AliExpress

I found this one in ali www.aliexpress.com/item/1005004517035478.html

@@josipX you have to solder the iron pads of the PCB together with the pads on the Xiao, have you looked the guide with pictures? Maybe the the before and after pictures of soldering this part can help you understand github.com/rafaeldelboni/buildlogs/blob/main/totem-v0.3.md#xiao

@@zkullzero that's the expected behavior zmk.dev/docs/development/local-toolchain/build-flash#flashing > If your board supports USB Flashing Format (UF2), copy that file onto the root of the USB mass storage device for your board. The controller should flash your built firmware, unmount the USB storage device and automatically restart once flashing is complete. But I imagine that after it disconnects isn't behaving as it should right? That could be a faulty Xiao or something wrong with the soldering, did you tested the Xiao before soldering?

Interesting question! I think this is very personal and depends on the goals of the person who will use the keyboard. For me, each build feels like one step towards my endgame build. So far, Totem is my favorite-not only because it has the exact number of keys I need right now, but also because the design aesthetics and the available documentation are incredible, making the build experience amazing. If you're just entering this world, I think any Corne build is a great choice. I mainly used Corne variations for the past four years, and it's great. There are so many documents, custom cases, PCBs, and parts available that it’s an incredibly versatile option. Of all the Cornes I've built, I think the last one, the Bluetooth Choc Spaced, was my favorite because it's simple to build, and not having cables is incredible. I thought it would be a bad experience in Linux, but man, I was wrong.

@@rafaeldelboni Hi! From starting into the keyboard world (I don't own any fancy keyboards), what's a good entry point for someone that has never owned a split keyboard? Do they sell the one you mentioned, Cornes Bluetooth Choc Spaced, pre-built somewhere? If not, for someone that wants to ease in, what do you recommend?

​@@azaeldrm Hi! Yes, you can find some pre-soldered Corne keyboards online. I did a quick search and found one on Beekeeb: shop.beekeeb.com/product/presoldered-wireless-corne-keyboard/ By the way, I’m not affiliated with Beekeeb in any way.

@@pfuispinne are you GEIST? Thanks so much for your feedback and for making all your designs open source! That's incredibly generous of you. I have to say, of all the boards I've built, this one is by far the most beautiful and well-thought-out. It's truly a piece of art, and I've been happily using it since the day I built it. You're a real artist, and your comment totally made my day! Thanks again 😊

@@rafaeldelboni That's really so nice to read! Thank you!

Yes, both methods can work, but if you add the solder to the iron before applying it to the joint, I recommend using flux or solder with flux in its composition. This will help guide the solder to the right places. For the latter method-heating the wire and pad first-just be aware that some components, like LEDs, are sensitive to heat, so avoid holding the iron on the pads for too long.

Tem um link na descrição com todos os itens que comprei pra essa build github.com/rafaeldelboni/buildlogs/blob/main/totem-v0.3.md Mas os standoff eu peguei esses (os mesmo da build oficial) pt.aliexpress.com/item/1005006049595637.html

Opa eu normalmente usava 3mm :)

@@calmrain3524 yes you can solder the switch's directly on the PCB if you want so.

@@rafaeldelboni I did solder xiao today and it didnt get any voltage as it should, but when connecting with usb it does, bad soldedring i guess :(

@@calmrain3524 yeah doble check the solder, if there is any cold joint, if you have an multimeter to do some continuity checks. And more important is the pads bellow that can be hard to solder and they are related with the battery energy supply

@@rafaeldelboni i got it working (blinks after power switch on) add firmware, do you might know how to pair it because nothings pops up when i search for BT devices

@@calmrain3524 AFAIK If a profile has not been paired with a peer yet, ZMK automatically advertises itself as connectable. zmk.dev/docs/keymaps/behaviors/bluetooth

@@junio.coelho Tem grandes chances viu! Kkkkkkk

Ow, legal ver BR produzindo material. Não tem nada em português.

É realmente tem bem pouca informação, acho que atualmente o lugar que tem mais info em pt é o grupo do Telegram t.me/SplitMechBoardsBR

@@rafaeldelboni poxa, valeu. Eu entrei lá.

@@AkitoYamauchi I would recommend you to download the case STL files and opens in a editor where you can measure, here I used 6mm, but I don't think 7mm would be super diferent, you can always buy and try, my screws and standoffs in the video where some leftovers from other projects, but later I bought the right ones and replaced this things are usually very cheap. Here a print of the STL, where you can see that the standoffs doesn't need to be hex imgur.com/a/E8qxoOz

@@fizipcfx thanks! Yes It's in my plans :)

@@victorcamargo7926 yes I used the standard pins, but anything would work, like diode legs, copper wire or other pins from arduinos :)

5mm X 15mm X 22mm, since I live in Brazil and I bought mine in a local store like ebay (produto.mercadolivre.com.br/MLB-3132175293-bateria-140-mah-37v-2-fios-5mm-x-15mm-x-22mm-501522-_JM?quantity=4).

Thanks for your feedback, yeah the battery is kinda hard find, but the only restrictions are the voltage 3.7v (if I'm not mistaken) and the size that would fit in the case (5mm X 15mm X 22mm), I live in Brazil and I bought mine in a local store like ebay (produto.mercadolivre.com.br/MLB-3132175293-bateria-140-mah-37v-2-fios-5mm-x-15mm-x-22mm-501522-_JM?quantity=4). But usually I had lucky buying batteries form Aliexpress at the time I was searching the time to ship was absurdly high, but I do recommend buying the batts there :)

@@Tasty_sand not yet, I will do so, just need to buy a new Xiao :)

Possibly! I just need to buy another Xiao and test this setup, but I'm having good battery time using the deep sleep zmk config.

@@rafaeldelboni I hope you make that one video. Thankyou very much

😂 Are you linking the keyboard so far?

@@rafaeldelboni yeah I love it, it’s my first complete build, though I’ve used a Corne for the last two years

Dude I just realized that I used to follow you on Twitter! You are such skilled gamedev and artist! Thank you for all your work :) And yes, seeeds are great and cheap microcontrollers, I want to use then in everything in home now haha

Thanks ❤️ It took some days to get used to it, coming from the corne, but I'm really liking so far. Using it mainly since the day I built :)

Thanks for the kind words, do it is a great and fun experience!

Personally I never tested, but I know some folks that say that it works super fine.

@@rafaeldelboni thanks for the quick replay! I'll give them a try and post my results here.

@@TheEyalYemini cool, yes please do so

@@rafaeldelboni btw is there a wireless version of the board with hot swap capabilities?

@@TheEyalYemini I think you probably could use the legacy Corne Choc v2.1.0 with a Nice!Nano instead a Pro Micro github.com/foostan/crkbd/releases/tag/corne-chocolate-v2.1.0

Olá, não essa PCB em específico é toda feita pensando me switch chocs. Recomendo usar o projeto da PCB oficial pra usar switch cherry github.com/foostan/crkbd

muito obrigado

Oi, o repositório do teclado mudou muito da época que montei, mas dei uma procurada pra você e tenho quase 100% de certeza que é esse arquivo aqui: github.com/foostan/crkbd/blob/main/plates/3x6/svg/plate-cherrymx.svg

Esses arquivos são da v4, ele removeu tudo da v3 e abaixo do repo, toma cuidado

E furo os dedos tbm 🤣

@@rafaeldelboni kkkkkkkk, você achou as nice!nanos por um preço razoável? Só encontro por ~$30

@@alef97 tem o supermini, versão chinesa do nice!nano, eu pessoalmente nunca usei, mas conheço uma galera que diz que é muito bom. www.aliexpress.com/item/1005006035505133.html

@@rafaeldelboni hmm interessante, acho que vou pegar aqui, só não sei se serve nas minhas placas corne v3, vi que vc usou 2.1, seguiu algum build guide ou só foi fazendo e vendo o que dava certo que nem eu?

@@alef97essa build é focada no switch do tipo chocolate e o fato se ser wireless, essa pcb ela tem o espaçamento pensado melhor pra esse tipo de switch e tbm tem como soldar switch de on/off pra bateria. O v3, até o momento só tem pcb pro switch tradicional cherry.

Hey it utilize zmk.dev as firmware and it's super flexible to configure. You can check my personal config here: github.com/rafaeldelboni/zmk-choc-corne, just search for a .keymap file :)

@rafaeldelboni I really appreciate you replying. The design of this is going to really help my cubital tunnel not helped by overstretching my pinkies on traditional keyboards. Can't thank you enough!! ☺️

Eu normalmente compro tudo no Aliexpress pesquisa por "Cherry blank keycaps" normalmente vem bastante coisa :)

I used this variation: github.com/davidphilipbarr/Choc-Spaced-Corne/tree/main/chocorne-switch There is a link in the description with more information about the build.

Eai Victor, comprei a grande maioria das peças no Aliexpress (tem um link na descrição), na época não fui taxado, mas atualmente o site já taxa automaticamente compras acima de 50usd. Recomendo fazer vários pacotes com compras de baixo valor e pra switches e keycaps eu recentemente comprei na Chosfox e não fui taxado.

Eu nunca achei/procurei esse tipo de pino fêmea, vc quer aproveitar as pernas que já vem no microcontrolador né? Se ver os teclados mais recentes, eu achei uma alternativa bem melhor do que o fio de cobre :)

Check my guide with images, maybe it can help you better than the video, but the diodezls, LEDs and the switch hotswaps are in the different side of the microcontroller, reset and tres connector github.com/rafaeldelboni/buildlogs/blob/main/crkbd-v3.md#solder-pcb-top-components

will have a look, ty!! @@rafaeldelboni

I think those where 3mm, but 2mm works fine as well is the same thickness of the PCB.

Isopropyl alcohol :)

Hey, yes there is some 7mm M2 spacers between the PCB and the bottom plate. You can see them here github.com/rafaeldelboni/buildlogs/blob/main/crkbd-v3.md#mount-the-case

i just saw that 😁

Uma fortuna é muito relativo, mas o preço varia bastante de acordo com o dólar, frete das peças e taxação na importação pode variar de 500-1000 reais. Se quiser que alguém monte um pra você tem um pessoal nesse grupo do telegram que oferece esse serviço. t.me/SplitMechBoardsBR

Long time I did this build, but looking at the docs looks like it where used to decide the side of the board (left or right), but seems that the firmware handle this now, so probably it's just used to set voltage to the Underglow LEDs (not sure) github.com/omkbd/ErgoDash/blob/master/Doc/build-en.md#5-underglow-led-optional

In the description there is a link describing all the parts and the link I used to buy the parts. github.com/rafaeldelboni/buildlogs/blob/main/crkbd-choco-v2.1.0.md#part-list

Glad you liked and thanks for the feedback :)
