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.

wondering if it is faster for you?

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.

a soldering iron at 360 degree celcius

[–] pca006132@lemmy.world 3 points 1 year ago

yes this is how I did it!

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

 

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.
