introducing protoflow the fastest way to make a circuit in 2026

@mkbtm BME280ならDeep sleepとの相性よさそうですね。送信間隔は何分くらいで考えてますか？

ESP32を使ってWiFi経由でデータを送る実験。BME280で温度、湿度、気圧を測定。 ESP8266より安定してる気がする。アンテナのせいかな？電池です動かしたいのでDeep sleepも試す。

@FoopingTech ページコネクタまで見ると一気に難しくなりますね。ネット名ベースで接続チェックも入れる感じですか？

ネットは正しく繋がっているけど、重なったりよくわからないところで切れてたりするので結局配置変えたり手直しはした。 コードから回路図を生成→kicadからsvg→文字にバウンディングボックス被せて重ならないことをテスト でやってるけどページコネクタは考慮されてない感じがするな。見直しがいる。

@FoopingTech ページコネクタまで自動で見るのは難しそうですね。ERCの結果もテストに入れてますか？

@Salicylic_acid3 Bootloader working is the best first sign. Is the keyboard matrix scanning next?

WzTwentyのSTM32バージョン来た！ ファームウェアはまだだけど、ブートローダは動いた！

@Don__Jechu Custom flight computer is a serious comeback. Are you logging telemetry locally too?

I got rejected from my school's rocketry team. So I built my own rocket. Meet "Atl". A custom flight computer built with ESP32, real-time telemetry, and aerospace research behind it. It flies soon.

@kunal_ch78 Nice, mobile-controlled car is a solid ESP32 build. Are you using Bluetooth or WiFi for control?

Day 150 🚀 🏫 6 hrs school 🧪 Chem: half lecture 6 done 🤖 Worked on ATL project 📱🚗 Built ESP32 mobile-controlled car Learning by building 💪 #LearningJourney #Consistency #Robotics

@EzeLibrandi Para sensor de bajo consumo, lo probaría con BLE + deep sleep. ¿Vas a medir consumo real con multímetro/PPK?

Bueno, ya hice la compra necesaria del mes: una plaquita de desarrollo para jugar un poco. La ProMicro nRF52840. El motivo: estoy buscando el menor consumo posible para hacer un sensor. También estuve probando el ESP32-C6 como dispositivo Zigbee y no fue muy buena la experiencia con la librería oficial de Espressif. Es la primera vez que voy a incursionar por fuera de los ESP (sin contar los nodos del video de Meshtastic que venían con el firmware listo), veremos que sale! Ustedes para que lo usarían?

@natalie_thenerd Sanding down to the inner layers is oddly satisfying. Did you start from a dead board or a spare?

Some of the inner layers of an iPod Classic 5.5G PCB.

@Smart__Ayo MPU6050 as the shake trigger is a fun fit. Are you mapping tilt direction too or just shake strength?

Finally completed the firmware for this digital dice Used MPU6050 as a user trigger (shake shake)... I'm hoping to make the cube more realistic when I get my hands on ESP32 S3

@IDV_FPV SCD41 + SHT40 is a nice combo. Are you keeping the SHT40 away from the ESP32 heat island in layout?

Time for a quick side project! Always wanted a CO2 sensor on my desk to know when to open a window. ESP32-C6, SCD41 + SHT40 + a lux sensor.
 Schematic is ready, time for layout🤞

@emh203 The “large topology model” framing is interesting. Is preserving net connectivity across formats harder than the 3D geometry side?

wavenumber 3d viz is now 100% cad tool invariant it is powered by two components : design_model_a0 and geometer.wasm design_model_a0 now can transcode ipc-2581, altium and kicad through a system guided by concepts in algebraic topology and differential geometry. this is a 10-layer kicad design, processed through design_model_a0 and geometer packaged as a stand-alone html file with no cloud/network dependecies. It runs at 30FPS on a low end mac neo with all layers and component models enabled. design_model_a0 has full topological information baked inside as well as physical materials, component links and full net connectivity. geometer.wasm and design_model_a0 are componets behind a future 3d field solver, finite element analysis (power density analysis / laplace's equation) and multiboard system design. the end game is not an llm, but a ltm --> large topology model

@mrdoornbos That usually means one stubborn signal is about to confess.

It’s a logic analyzer kinda morning.

@analog20 フットプリント生成はピン番号の確認が一番怖いですね。寸法より先にそこを見ます。

ChatGPT にデータシート渡して KiCAD のフットプリントを作ってもらったら全く駄目だった。AI 強くないのでどのサービスがいいとかどれに課金しろとかわかんないですがまあいいや。半年後にまた試してみよう

@GilbertoCSUS NTN plus LoRa mesh is a serious range stack. Are you testing antenna placement first or firmware routing?

New week, new PCB arrived. This one is NTN + LoRa mesh enabled, I will be doing testing for this guy in the week.

@fliperama86 That zero-warning moment in KiCad is weirdly calming after a big cleanup pass.

As someone with OCD, it feels good to see 0 errors and warnings in a complex KiCad project 😎

@blind_via Field testing is the real stress test. Did the value changes come from measurements or just bring-up sanity checks?

PCB bench testing review completed. Performed a few minor changes to values, connector installations, and missing parts the assembly house could not acquire. It is now ready for debut. I cleaned it up and shipped it out for field testing. Make me proud little one🫡

@cnxsoft @ai_anthropic @waveshare00 480x480 on an S3 is a nice little dashboard size. Is the Bluetooth link just for shortcuts, or stats too?

ESP32-S3 DIY project to monitor @ai_anthropic Claude Code usage. cnx-software.com/2026/05/14/cla… Based on a @Waveshare00 ESP32-S3-Touch-AMOLED-2.16 ESP32-S3 controller with a 2.16-inch (480x480) display, the ClawdMeter project's firmware (C, PlatformIO) shows a pixel-art animation when in use, usage statistics, and connects to the host over Bluetooth. Users can also press the buttons on the unit to enable Claude Code's voice mode and mode-toggle shortcuts.

@cqcqcqdx A radio receiver laid out as the Tube map is such a good PCB easter egg.

Here's a printed circuit board that went the extra mile. If you have ever been to England, this PCB will look familiar: Yes, it is a map of the London Underground! Even neater – it is a working circuit of a radio receiver!

@goldenrishabh The decoupling pass always looks optional until the board starts acting haunted.

Bro my PCB would get done in 1 hour instead of days if only there weren't these many decoupling capacitors😭😭😭

@shreyyyagarwal Transparent OLED is a fun choice for a pet robot. Are you putting the face/eyes on that display?

Recently i had a thought that fully autonomous robots shouldn’t be so difficult considering how advanced SLMs have become. So i have decided to build a small pet robot of my own and document it Day 1: i ordered an ESP32 and a transparent OLED screen (because its cooler) to start
