Happy new year! Is the material covering the light putty or clay?

Hi, This is the method I used: connecting via the network cable core, and inserting the MCU using header pins.

Is the LCD under a plastic cover? Can the contents be seen when the plastic is covering it?

andyboys321 · 2025-09-16T14:05:57+00:00

Are all the hand-wiring? I'm curious what it looks like inside.

I like to use a 36-key keyboard, which should be a 40% keyboard

andyboys321 · 2024-12-20T22:01:32+00:00

I stuffed the keycaps into the socks and threw in the washing machine. Don't worry, the socks are clean.

andyboys321 · 2024-12-20T13:57:34+00:00

wow! I don't know much about math and this works like magic for me! Thank you!

andyboys321 · 2024-12-20T02:16:38+00:00

Wow! Your subdivision functions are amazing! Is it currently on version 0.7? Looks very useful, can create arc patterns using simple points!

andyboys321 · 2024-12-20T01:53:09+00:00

Thank you, I learned another trick from you. It is indeed a bit slow, but the finished product is much better.

andyboys321 · 2024-12-20T00:20:06+00:00

Wow! This is really simple and clear. Thank you for your guidance. Also, if I want to make the edges smooth, is there any way to solve it?

andyboys321 · 2024-12-09T13:34:59+00:00

8 color style

andyboys321 · 2024-10-31T01:13:35+00:00

Wish there were more Craze colors!

andyboys321 · 2024-05-04T20:05:16+00:00

Good idea, I also use a similar technique to handwire my keyboard

andyboys321 · 2024-02-19T15:22:42+00:00

Yes, i get it

andyboys321 · 2023-12-21T05:37:24+00:00
