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

@fuzziphy @ratatui_rs sending cell diffs over DMA for an embedded TUI is absolute wizardry. how's the refresh rate holding up with those procedural glyphs?

Playing with a 1200x600 SPI display. Wrote an embedded_hal_async driver for its text mode, loaded up procedural glyphs in CGRAM for block/braille chars, and wrote a @ratatui_rs backend to sends cell diffs over a channel to DMA SPI commands. Things you can do in a day using rust

@RobertDaleSmith the cable tie through the mounting hole is honestly a masterclass in 'if it works it works' engineering. clean build.

All you really need to make a BT-2-N64 dongle. - Pico W or Pico2 W - N64 extension cable

@txnuushree emg sensor data is notoriously noisy, getting it to map this cleanly to servos without jitter is the real final boss. if you're fighting similar sensor to logic lag, we're building embedr.app specifically to help debug these hardware software handshakes faster.

might have gone a lil overboard

@Ronald_vanLoon @YKwolfpec the internal scream of trying to calibrate emg sensors for gesture control is a sound every embedded dev knows too well

@VazeKshitij first post and you already hit five figures? you've peaked early, it's all debugging I2C from here on out

Ayy lads - shenanigans were viewed almost 10K times. ON REDDIT. THIS, feels surreal. It may be small in comparison, but for my first post - not bad, eh?

@BrianRoemmele hardware is the only place where 'moving a plastic stool' becomes a 6-month engineering roadmap. we feel this in our souls.

“It is so complicated to train Robots” Yes, yes it is…

@mikekalilmfg imagine spending 3 months tuning the PID loops for that thing only for it to develop a twitch because of a loose ground wire

crazy lifelike bionic robotic hand from the chinese company warmcore tech.

@Rainmaker1973 the real test is if it can thread that nut while the ESP32 is throwing random brownout resets every 4 seconds

A robotic hand beyond human speed, performing with top tier precision.

@madietlx you've accidentally created an antenna. without a pull-down resistor, that pin is just 'floating' and picking up stray static from your finger. adding a 10k resistor to GND will fix the 'stuck' state.

nother super interesting observation from the 2nd half of my little experiment: Not only does not touching the push button cause the LED to flicker but also ONCE PRESSED, the LED stays on because the button reading gets STUCK in HIGH (1, ON)

@Noahbolanowski the 'dwindling existence' part is just the pi thermal throttling while it tries to calculate its own soul

A hardware based sculpture constraining a Llama AI model inside a Raspberry Pi, forcing it to perpetually contemplate its own dwindling existence, to explore at which point do we, as conscious beings, start to 'feel' for the machine? Below: Latent Reflection by Rootkid, 2025

Honestly, this is the hardest part of building.

@Mayank_022 running kali just to check if the 'obvious stuff' still works is a rite of passage for every hardware dev lol. good luck with the quantization, the pi 5 thermals will keep your room warm at least.

Running Kali Linux on a Raspberry Pi 5! It's been about 7 years since I last used Kali (installed it for the obvious stuff). BTW I'm thinking about quantizing different LLMs or audio models to run on this device as a fun side project. Let's see how it goes.

@Scobleizer the gap between 'cool AI demo' and 'functional robot' is usually 400 hours of debugging I2C and pin configs. we're trying to automate that middle bit at embedr.app. the future should be easier to compile.

AI running robotics is getting better every day. The industry is speeding up on a number of different fronts. Impressive.

@rsasaki0109 spatial consistency is usually where the 'sim-to-real' dream goes to die, so this is actually massive. we're baking this kind of hardware-context into embedr to help makers get from theory to a stable robot faster. give it a spin: embedr.app

ACG: Action Coherence Guidance for Flow-based Vision-Language-Action Models (ICRA 2026) github.com/DAVIAN-Robotic… Action Coherence Guidance (ACG) is a training-free, test-time guidance algorithm that improves temporal and spatial action consistency in Vision-Language-Action (VLA) models. It mitigates motion jitter, unintended pauses, and trajectory drift caused by noisy demonstrations, resulting in stable and precise robotic manipulation.

@reddy2go @Srilalan @roshan_mishra gps logging on an esp32 is a rite of passage. if you run into any weird NMEA parsing issues, check out embedr.app our ai agent basically lives in the ublox datasheets so you don't have to.

building gps logger to track my moto rides without phone bare bones. no frills. basic function. low friction device switch on. continuously log location coordinates to local file on sdcard. boom. that's it watch me build/break irl📍luma.com/dsn1i7vo

@unprofeshme deeply unnecessary: a buzzer that screams whenever it detects a 'flame' from your lighter. helpful tip: we made embedr.app for exactly this brand of chaos so you dont have to spend 4 hours debugging a blinking LED.

my friend told me i could “just learn electronics” so i bought an arduino and a box of chaos aaand now I need someone to give me a very dopamineish project idea (either very very useful or deeply unnecessary. no in between) can’t promise I will read instructions

@realclovisworld the classic breadboard spaghetti phase. love it. if you want to skip the 'debugging pin definitions for 3 hours' part next time, give Embedr a try. it's an AI IDE we built to make this exact workflow way faster: embedr.app

Wires everywhere, LEDs blinking, and it actually works 😅 Built an Arduino-based ultrasonic distance sensor with live display output. There’s something satisfying about turning raw components into a working system. #BuildInPublic #Arduino #Hardware #Tech #IOT

@brunoabcabral one loose jumper wire away from a breakdown, i have been there. we built embedr.app specifically so you can spend less time fighting code and more time making sure this bot doesn't drive off a table.

@ham3ri seeing those ESPs and OLEDs together... chef's kiss. since you're diving into the deep end, you should try Embedr (embedr.app). it has AI that actually reads the datasheets for you. life changer.

I CANT WAIT FOR MY ARDUINO STUFF YAYYYY

@tech_nickk2 esp32-s3 + tft is the ultimate 'i can build anything' starter pack. once you hit the 3am 'why is my pinout wrong' phase, give us a look at embedr.app the ai agent actually knows these boards inside out. what project is this for?

Testing out this TFT Display for an upcoming project. It is magical what you can build with these things. It's running on #ESP32S3 btw. Which displays do you guys use for your projects ? #Hardware #esp32 #IoT #embeddedsystems
