Cascade Kobayashi @cascade.moe · 06/04/2025It's a common feature for most EDA softwares. Usually, fifferent layers have different default colors, like top layer is red and bottom layer is blue. You can turn of custom net color and they will show in the default colors. 000
Cascade Kobayashi @cascade.moe · 04/04/2025They are actually net colors~ You can assign colors to nets or net classes in this tab. I would prefer assigning different protocols & power rails with different colors. 100
Cascade Kobayashi @cascade.moe · 03/04/2025WIP Isn't it strange to use a STM32H7 + HS PHY, with a old DAC chip (CS4398) which is almost as old as me...? But it's interesting that, CS4398 actually lived 20 years and it's still not discontinued. 020
Cascade Kobayashi @cascade.moe · 02/04/2025Yes, they are feedthrough capacitors. They can efficiently filter out high frequency interferences & spikes. I haven't used them before... But one member in a group recommended them and I want to give it a try. 000
Cascade Kobayashi @cascade.moe · 02/04/2025WIP Price of STM32 microcontrollers are rising, the interface chip is twice more expensive than that DAC chip... Maybe I will use CS43131 later, although it's not challenging as it integrated an HP-AMP which can simplify the design. 140
Cascade Kobayashi @cascade.moe · 31/03/20253rd order low-pass filter. A simple RC filter followed by a Sallen-key filter. The latter filter is compensated to achieve flat group delay in pass band. 三階低通濾波器，一個簡單 RC 濾波器之後跟著一個 Sallen-key filter. 後者經過補償，可以在通帶中實現平緩的群延遲。 050
Cascade Kobayashi @cascade.moe · 29/03/2025DAWN PRO They may have better performance, but I can hardly identify the difference between playback devices with my ears. Test result is slightly better than on board audio, but I suppose the result is limited by the recording device & testing environment, which are quite bad. 070
Cascade Kobayashi @cascade.moe · 29/03/2025Tested my CS4398 DAC (Rev 1), its performace isn't as worse as I expected... Although THD+N is really bad (0.02% @ -5dB, 0.01% or 0.008% @ -10dB) 041
Cascade Kobayashi @cascade.moe · 27/03/2025From the experience on last CS4398 DAC project, I decided to make a new CS4398, with STM32H7 as interface and some second hand OP1612 apmlifiers. H750 is quite cheap now. It's very fast, plus bunches of peripherals that I may or may not use. 040
Cascade Kobayashi @cascade.moe · 20/03/2025沒活了，找點東西臨摹。這次是小塗真紀。 是聽講座的時候開始摸的，不過沒有怎麼優化線條，所以大概顯得很亂。 原作 Pixiv ID: 126483504 040
Cascade Kobayashi @cascade.moe · 18/03/2025親友們說想看我 cos M200。 沒玩過 Girls' Frontline，但大概還是略有了解。 只是感覺自己的外貌過不了自己這一關呢。 My friends wanted to see me cosplay M200. Although I never played Girls' Frontline, I know some of it. I just don't think I'll look good enough to satisfy myself. 0100

Cascade Kobayashi @cascade.moe · 07/03/2025I searched on Chinese version of LCSC, RP2350A is also missing but RP2350B is still available 🤔 Maybe they encountered some supply chain issues I guess? 000
