I think you should probably use a CAD instead of graphics software to design...
Nice, I can buy ch582f dev board for 2 dollars. Still very cheap!
Yeah WCH make some really cheap chips. Apart from ch552, there is also a family of BLE chips such as ch571f that is much more efficient than ESP32 (from online sources) and is very cheap. You can get the chip for half a dollar (https://www.aliexpress.com/item/1005005974200193.html) and a development board for less than 3 dollars (https://www.aliexpress.com/item/1005005974200193.html). When I bought it on taobao, it is actually around 1.3 dollars.
The downside is that software support does not exist (yet), so will have to try and make a firmware for it. I haven't yet found time as I was working on manifold things.
There were efforts trying to do make this simpler, but it was abandoned. See https://github.com/openscad/openscad/issues/4743 and related PR.
I just did it for the wrist rest, as that is the part your wrist will touch regularly. It is too much work to cut many holes if you want to cover the plate, and I don't think it will be much cleaner comparing with bare printed surface. You still need regular cleaning.
Indeed, the major cost is labor cost. I was iterating on the design once a month and do some very simple tweaking (change the screw location for example). Because I want to make sure that the entire thing works, I need to solder everything for each cycle. Due to the lack of components, I have to disassemble old working keyboard to make a new one. I probably disassembled 4 or more in total. I was looking to sell the old one for $100, but no one was interested. I guess a lot of mechanical keyboard users are probably not used to split keyboard and DIY keyboards, so are not willing to buy it.
Not sure about others, I tried to sell me keyboard but without success, maybe split keyboards are a bit too niche and no one near me (HK) is interested. I just disassembled the keyboars to scrap the components for the next build, which is a bit sad considering a significant amount of time is spent on assembling it.
The main problem with SLA is the material and size. I don't think SLA can print ABS?
For wrist rest, you can stick a piece of TU leather to cover the printed surface, so it will look nice, be clean and comfortable. Not sure if TPU is sufficiently soft if you want a soft wrist rest, you would probably need something like silicone.
This looks pretty! Wondering where you guys get those fancy choc keycaps as well, I usually go to aliexpress (taobao in hk) and choc keycaps are much more expensive comparing to the normal kind of keycaps. I can usually get 60 normal keycaps for around $10 USD, but the price easily doubles for choc.
yeah, they are quite delicate. I wanted to use thicker ones but it is hard to get thick magnet wires. I never tried dropping them so idk, I guess making them less tensioned would help a bit
No need to bend the legs, no need to do wire stripping. I did this in 30 minutes casually... I guess the full halve will take around 1 hour
I am a vim user (and use vim keybinding for web browsing), so I rarely need to use both my mouse and keyboard at the same time.
Geometry library for topological robustness. Contribute to elalish/manifold development by creating an account on GitHub.
Just wanted to share the manifold library to 3D printing enthusiasts.
It is a fast and robust mesh boolean library in C++ with a typescript API that you can use in your browser! It has most of the operations supported by OpenSCAD, but without import svg and minkowski. The operation is so fast that even OpenSCAD is using it as a backend (experimental option in nightly) and get up to 250x performance improvement for some models.
40% low profile keyboard?
