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.
Glad to say that reaching out to the #maker supply folks at #Electrodragon received a prompt response.
My order was apparently dispatched already, just the admin work was a bit slow. Hope they're continuing to be the great source they've been for parts and gizmos for several years.
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?
Aber ja, einfach nichts in den Innenraum packen, was da nicht rein muss.
Die DHT Serien geben digitale Werte zurück, da können die Kabel auch etwas länger sein. Dann könnte man z.B. auch einen Sensor in den unteren Bereich am Stamm, einen zwischen die Blattmasse und einen neben den AKF hängen.
Der DHT22 ist generell etwas stabiler, aber auch nicht ganz so leicht zu bekommen und teurer.
Aber es gibt noch z.B. BME280 und HTU21 Sensoren, die mit Breakoutboards auch einfach zu verwenden sind.
Kann man später auch immer noch wechseln.
Viel Spaß mit dem Sammeln von Erfahrungen. Das macht voll Spaß und ist so interessant wie lehrreich.
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
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...
Its also just neat to see European governments funding this kind of thing (this one from the Netherlands, I believe MicroG gets some German government support.)
I know its peanuts of funding relatively speaking, and hardly a sustainable model by itself, but its hard to.imagine the Australian government (for example) going anywhere near this kind of thing.
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!
