New Open Source Hardware board MIPI-HDMI allow ESP32-P4-DevKit to display to large HDMI TVs https://olimex.wordpress.com/2025/07/25/mipi-hdmi-is-open-source-hardware-mipi-dsi-converter-to-dvi-hdmi-which-works-with-esp32-p4-devkit/ #esp32 #espressif #esp32p4 #hdmi #mipi
Woot, just finished implementing my first GitHub / Forgejo Actions which allows me to programmatically push meshcore builds to my radios on the roof from the comfort of my browser.
It currently only supports deploying to esp32s3 based LoRa devices so far.
Since I failed to Receive Signal of my #433mhz remote , using #arduino uno or #esp32 vroom32 or one of two usw TTL Adapters in Combination with a cc1001 tranceiver , mx-rm-5v Receiver or superheterodyne Receiver - I will visit the @RaumZeitLabor hoping someone might Help me Out with an osciloskope
„Ratatui - Are We Embedded Yet?” talk is finally online!
I gave the same talk at Rust Gdansk 9 and Rust Poland 1, this recording is from the second meetup.
It’s my first talk (not counting lightning talks) and I struggle with public speaking (trying to change that) but I hope you like it.
Btw. Terminal/presentation had to be re-recorded afterwards so that’s why typing is not in sync.
Someone asked how play multiple simultaneous CD-quality WAVs from an SD card to I2S DAC on ESP32 in CircuitPython. Turns out: possible! Can get a bit glitchy if doing USB stuff tho https://www.youtube.com/watch?v=97OA6L9PLCg

I posted a couple of new 3D models today. A vertical holder for an M5Stack Atom Lite, and a parametric modular ramp for RC cars. You can download them for free from my Maker World profile - https://makerworld.com/en/@sylumer

New embedded Rust milestone!
I connected my electric guitar to ESP32 with an amplifier circuit and visualized the played notes with @ratatui_rs

CHARMING SERVERS
a first bunch of server charms has been released into the wild!
thank you to all who participated in our workshop on saturday (and apologies to those who couldn't take part bc it was full). so cool to see all your sparkling ideas for webpages and case designs materialize.
follow up on some lovely documentation and the * server charms manifesto *

Hallo an die Maker-Gemeinde da draußen
Habt ihr einen Tipp für mich, mit welchem Buch/Heft/Zeitschrift/Website ich am besten mit einem niederschwelligen Einstieg in die Welt von #Arduino und/oder #ESP32 starte?
Vor allem die Elektrik-Grundlagen, die Anschlüsse und das Auslesen/Ansteuern von Zeugs sollten dabei gut mit abgedeckt sein (High-Level programmieren kann ich schon).
Ich nehm gerne auf ein Tipp für ein gutes Starter-Set
Is there anyone in the room with knowledge about #ESP32 microcontrollers?
I am playing with a #Waveshare development board that has an #AMOLED and a touchscreen, and it says it has built-in #SH8601 display driver and #FT3168 capacitive touch chip, using #QSPI and #I2C communication respectively.
https://www.waveshare.com/product/arduino/boards-kits/esp32-s3-touch-amoled-1.8.htm
It directly works in #Arduino with #C, but I am trying to make it work with #MicroPython.
Before I spend effort trying to compile it with #LVGL, I want to know if I could print a "Hello World" to the screen as is, and while my mind tells me that I need a driver, the sentence "built-in display driver using QSPI" makes me think that I could eventually use the display without code drivers, but I don't know how.
I'd love to see an example, if it's possible, or to be pointed to any resources that I can read in this regard. I am complete newbie.
Re-posts are appreciated.
Thank in advance

The ESP32 Rainbow is close to shipping!!
https://www.crowdsupply.com/atomic14/esp32-rainbow
The ESP32 Rainbow is a modern recreation of the Sinclair ZX Spectrum, It emulates the look and feel of the original 48K machine, replicating its iconic keyboard. It has a built-in color LCD, a microSD card slot for storage, and USB Type-C port for power.
You can run #Zephyr applications on QEMU, which is great for early development, debugging, and #CICD workflows. Check out my tutorial for using Espressif’s QEMU fork for emulating #ESP32 applications made with Zephyr: https://shawnhymel.com/2807/how-to-run-an-esp32-zephyr-application-on-espressifs-qemu/ #embedded #programming
I assembled a bunch of those modules and ran a quick test. Looks like the chips work so i suppose i can start flashing the actual slime vr firmware onto it
