Embedr

@adafruit taking Embedr for a spin is the crossover event we didn't know we needed! thanks so much for the love. 🙏 see what all the fuss is about - try Embedr free at embedr.app

@siberian_forest those 0Ω jumpers aren't defeat. they're field modifications with excellent PR.

泣きながら回路図を基板に落としました。 屈辱の0Ω抵抗3本でフィニッシュです。 自作でこの作業が1番辛いけど1番楽しいかもしれない…(愛憎入り混じる複雑な感情)

@nzevh_ RK3588 said “three Superspeed ports, no more” and you chose violence with a 4 port hub

Day 54 of creating a laptop from scratch its weekend.... so i was working on the 2x USB 3.1 Gen 1 Type-A ports, but the RK3588 only supports 3 Superspeed ports, of which two of them are used by the Type-C ports so i upgraded the hub from the GL3523(2 ports) to the USB5744(4 ports) to support them and the macro pad and possibly a 4G/5G module via M.2 connector

@stisov16 4X speed and the ball still looks like it has the upper hand

@1nkfy mac writes the firmware, linux processes the consequences. immaculate division of labor

mac writes the firmware, the linux box runs the signal pipeline. rate it

@Zunda_Rice_Cake that DP100 is smaller than the board sitting on it

DP100ちっさ!!(驚嘆)

@ichirowo the board has entered its ‘one more jumper wire’ era

片面実装で入る気がしないが....

@jg1eic “don’t expect commercial quality” is exactly what someone says before making a surprisingly good one

KEYER XS用の簡易パドルも少しずつ仕上がってきました。打ちやすさをもう少し改善していきたいです。ただ、市販のパドルみたいな期待はしないでください😅

@Zunda_Rice_Cake the helping hands stand, power gear, and RollerCAN... this is a full electronics side quest

ポータブルな電源と追加のRollerCAN、その他諸々を入手!!!!

@JeremySCook @HarborFreight this is one 3D printed divider away from becoming a full PCB parts civilization

@doityourselfecu that tiny XIAO camera has entered its low budget dashcam era

カメラモジュール買ってみた！ CANモジュールと同期して、動画撮っちゃうよ！ って思ったけど、思ったより解像度良くない🥺

@magicarchtec the real jump scare is finding X48M X1/X2 hiding in the pin map after assuming it wanted a clock input

マザーボード観察しててびっくり。 CPU、お前発振器入力じゃなくて発振子入力なんだ。 RTCのクロック入力端子もある。 この部品配置は発振子だよな？マッチングとかソケット経由のこの距離やるのか？そんなにコスト削減厳しいのか？と思ってピンアサイン確認したら震えた。

@shi78ge If the 1000uF still doesn’t tame the dips, a separate motor supply or current limited ramp may help more than adding even more capacitance.

アリエクでレゴと組み合わせやすいモータを調達した。瞬間的な電圧降下が結構あるので、1000uFのコンデンサを5V-GND間に入れてます。 部品気になる方は以下のリンク参照 a.aliexpress.com/_c4PU05gJ

@jssnu_robocon speed king with the wiring density of a small data center

The King of speed

@TriedAngled the real question: does it still work, or does it immediately need three new solder joints?

visiting my family and found the first project I ever did, 6 or 7 years ago. A glove that tracks finger motion. I wonder if it still works!

@nahitafu When you finally power it up, please tell us how many datasheet footnotes became real world problems.

そういえばワイもADF4382Aの信号発生器を設計していたんだった。忙しすぎてもう3か月以上放置している。今の仕事を早く片付けて試してみたい。

@splinedrive @machdyne Kintex 7 power, breadboard implementation

Why it work? @machdyne

@marimo_linux the Arduino becoming its own little power monitoring department is extremely satisfying

昇圧回路もArduinoで電圧測定している 半分に分圧して2.5Vなので5V得られてる

@delicious1229 negative feedback next? the gain monster is about to become a stability monster

2SC3422/2SA1359の出力段を追加して波形潰さずに0.75Wまで出力できるようになったー😊 次は負帰還の追加かな

@IObrizio KiCad said “trust me” and the enclosure agreed.

It fits! ✅

@IObrizio fit test looks clean. next boss fight: closing the lid without discovering one component is 2 mm too tall

Meanwhile I did a fit test.... And placed 2 screws. Looks good. Prototyping / Paper PCB
