Hmm, I've used #Electrodragon for many years. A smaller Asia/Pacific #electronics parts shop w a boutique feel. Small circuits, parts, modules, some used stuff, but fun all around.
They've been very good, and tho' a bit low on documentation I can usually get everything I acquire there working, tho' sometimes with a bit of effort.
A recent order isn't moving at all. Makes me worry they might be at the end of their run? Will try a query to see. Fingers crossed.
I've got this #ESP32 WROOM Opensmart board, works fine with #HomeAssistant. That is until I put any kind of ultrasound sensor on its power rails, and then the wifi doesn't work (5V) or it stalls the micro (3V3). Ah, you think, dud board. So I try a Pico W. Wifi works, but ultrasound doesn't (3V3). I have 3 different types of SR04-ish sensors and a bunch of MaxSonars. I have 3 ESP32's and 2 Pico W's. The sensors work on Arduinos. What am I missing?
I learned some days ago how #moisture gets trapped inside #sealed enclosures used for #electronics when exposed to daily cycles of heat and cold.
The cold creates lower pressure inside. If that overpowers the seals, then outside air gets sucked in, carrying moisture. This extra moisture can condense inside and accumulate at the bottom.
In the next warm part of the cycle, if some air is expelled because of the higher pressure, that moisture is not carried out because it is in a liquid state.🧵
Repeat this a lot of times, and you will get the electronic circuit diving inside the enclosure 😂
I want to measure how the humidity and pressure fluctuate inside an enclosure that I'm prototyping for an industrial composting temperature sensor, so I assembled a quick hack with an Adafruit ESP32 Feather V2 running SensorWatcher that will report that every 10 minutes. The sensors are an HTU31D for humidity and a BMP388 for pressure.🧵
So I had a look on the sigrok wiki, and I've narrowed it down to a couple but still looking for recommendations for a logic analysier that people have used. Looking for something a little better than the £10 streaming type - in the sub £100 price range. Sigrok compatability ( or works on linux and older versions (11.7) of OS X #electronics#esp32
... the cover: materialized and in its natural habitat.
The wall socket box was too shallow to hold a breaker, 24V transformer and #Esp32 board with a relay.
Not very aesthetic, but it covers all the door unlocking junk.
Anyone else here doing stuff with #CircuitPython on an #ESP32 board?
I got through the installation and I can edit and run code in the web editor now... but that stores the code directly on the board, which is rather inconvenient if I want to do things like put it in a git repo, and use an IDE for editing. I could edit the code on my laptop and then upload the files to the board through the web editor, but that seems very tedious.
Is there a tool that does some kind of automatic sync for this?
Quick question for all you far more knowledgable types. I noticed that after I put my esp32 custom board into deep sleep it settled to a draw ~23.5uA but 350ms later there was a gradual (over 100ms) increase up to 27.7uA after which it dropped back to ~23.5uA. This happens after each wake and deep sleep cycle, but only once per cycle.
I have a suspicion but I don't want to influence responses - plus I don't really know what I'm doing 😔 - Some obvious known pattern?
So I bought a bunch of stuff to build an #epaper#weather display based off an #esp32 board, sort of mixing and matching stuff up from a few project I had found.
I had assumed that the hardware would be supported by #esphome, but the amount of stuff that especially me actually supports is... Disappointingly low.
So, besides learning how esphome works, I now get to figure out how to add a 3rd party library in there and how to write a panel description so it can drive it.
Had similar long term ambitions on ESP8266 when I started esp-open-rtos a decade ago, but ended up being hired by Espressif instead. 😅
From inside we always had theoretical support for open sourcing more of the WiFi stack, but it was never going to become a priority unless some high tier client demanded it...
Hello World! Firefly Zero is an in-development handheld game console that runs #wasm and supports #BLE multiplayer. It is written by @orsinium in #Rust, runs on #ESP32, and will be fully open source (both software and hardware).
We already have a working desktop emulator and are getting a Rust and #golang SDK ready for alpha testing. Sounds fun? Stay tuned!
Their previous UI with TouchGfx had them locked in to STM32 devices, but choosing #Slint helped them to be flexible in their choice of silicon vendors.
I appreciate that they made this ESP32-C6 super small, BUT how am I supposed to work with this? Are there also tiny breadboards and tiny jumper wires that I can get?
