My first Digital Timepiece constructed entirely using PCBs. Rate my concept & share your thoughts. 😄 GitHub link: github.com/0101shift/Proj…

⌚Meet Project OAK : a digital timepiece blending analog elegance with digital simplicity. 🎨This project proves PCBs are more than circuits -they're a canvas , transformed by engineers into art. 💪At JLC, we are inspired by makers who push the boundaries of what's possible.

@blind_via @ImAnand_AI I believe it's just an attempt to bump down the advanced order to a standard order. I don't really understand it either.

Ordering PCBs was the most exciting thing I got to do in years. And I get to do it again real soon.

if you have decided who will build your pcb before your design is finished, have good communication with them about your design before you finish it.
Anand@ImAnand_AI

@thegertel @blind_via Oh, it looks like a uVia, you should get it checked with fab before sending Gerber.

@ImAnand_AI sure you can program the CPLD without a vendor programmer by using the firmware i'll download onto the RL78 i'll post a proper explanation after finishing the design and mention you

配線の見通しが立った🤗 全ピン無駄なく意味のある使い方ができた。 一人でやってるので部品選定から回路図、アートワークをアジャイル的にやるので終点が見えにくいが、峠は越えた感じがする。

高速な信号から引いていっている 今日中に何とか終えて一晩寝かせたいところ CPLDのクロックは100MHzを予定しています つまりHDLができれば10nsで好きなことができる (といってタイミング制約の沼に学生を嵌める)

@ImAnand_AI @Derek2137 I might have figure out it's quirks before I finish this revision, cause it could be useful to me right now

@ImAnand_AI @blind_via I use 0.3/0.45mm for boards that aren't too dense, but here I had to use 0.15 drill diameter and 0.47 via pad diameter (so 0.16mm annular ring width). But, they changes the sizes and clearances of all traces, pads and copper pours in the entire design.

@thegertel @blind_via What's the drill you usually use? Min is 0.3/0.45mm works perfect...

@AUDIY14 Interesting... Is it because of BOM? 🤔

Would you look at that, KiCAD 10 appears to have fixed the scrambling of PCB ref designators when updating symbols from schematic.

@moshimosikarate @imuuu_u These are TOP cool MOSFETs from Infineon. By pushing your thermal pads to top helps for better heat dissipation through active or passive cooling

Antennas... Also quick question, I have a connector right below the antenna as you see, how badly could it affect signal reception/transmission?
