Noch eine Ergänzung zu meinem Problem mit den Ausgaben auf dem Serial Monitor des #Wemos #D1Mini
Das Problem scheint nicht bei #PlatformIO oder #VSCode zu liegen.
Wenn ich mit #picocom die Daten der Schnittstelle ausgeben lasse erhalte ich auch nur kryptische Zeichen.

Mein #PlatformIO unter #Linux mit #VSCode will nicht so, wie ich es will.
Mein Programm wird auf den #Wemos #D1Mini hochgeladen.
Allerdings liefert die Ausgabe auf dem Serial Monitor nur kryptische Zeichen. Alles was sich ergoogeln läßt habe ich probiert und abgesichert.
Monitor und D1Mini laufen auf gleicher Baudrate (9600, 74880, 115200)
Auf beiden Seiten läuft die Übertragung als 8-N-1
Ausgabe, die ich bekomme: "␀␆␘␘�8888�8␘␞␘␀"

Hm, mein #Wemos D1 Pro (#ESP8266) will sich unter #Linux nicht flashen lassen. Schmeißt immer einen permission denied Error auf das /dev/ttyUSB0. Merkwürdig. In der Benutzergruppe Dialout ist mein User.
Ich werde mich mal morgen damit in Ruhe beschäftigen. Heute nicht mehr.

Очередное Интернет-радио на базе ESP8266, но с изюминкой

Да, это еще одно интернет-радио. Их уже сотни. Но в этой статье я хочу рассказать не только о самом устройстве, но и о одном из наших подходов, который мы применяем в IoT-разработке. Эти решения помогут вам упростить взаимодействие конечных пользователей с вашими устройствами.

Anyone got experience with the Wemos / LOLIN ESP32 S2 Mini dev boards? Need to build a circuit around an ESP32 (I need the hardware PWM) for an upcoming project and quite like the idea of making it as a PCB hat.

At first glance, this seems like something of a standard size - it's the same form factor as the Wemos D1 Mini and the shields are the same size too.

The new "Tank level sensor" project is almost ready! #esp8266 #wemos #homeassistant #homeautomation

Für alle meine #Renogy MPPT-Solar-Ladecontroller habe ich eine #esp8266 Platine, die mir die Daten als MQTT liefert (RNGBridge-Projekt von @enwi). Ein Controller hatte da immer wieder Aussetzer, bzw. die WebUI ließ sich nicht aufrufen oder nur sporadisch.

Langer Rede kurzer Sinn: Ein #Wemos #D1Mini kann auch "halb kaputt gehen".

Neuen ESP/D1Mini mit der Firmware geflasht und eingesetzt, läuft wieder.

Many years ago, I put together this little #Nokia5110 Screen with a #Wemos #D1Mini #ESP8266 - I don't remember what the original project was going to be. I never got the display to work right - actually it worked. But was hard to see.
I found this in a box of stuff yesterday, and thought, I'd try again. - After looking at the library I found a #Bias setting - a little playing around, and well it's still not perfect, but I can read it.
The issue with this screen is viewing angle.

so i've been holding down PIN 0 on my #ESP32 and rebooting it to put it in flash mode every time I've compiled/uploaded a sketch in #Arduino IDE and it turns out i didn't need to do that as the IDE would reboot the connected #wemos #s2mini into that mode automatically after compiling and well i've wasted a lot of time i didn't need to waste, huh.

Calibrating my #DIY #HomeAssistant #Wemos #ESP32 temperature sensor

It turns out stacking together the microcontroller and temperature sensor heats it up quite a bit.

"Venting" the sensor by spinning it in the air cools it by ~3°C. I already placed the stack vertically hanging in the air to allow for convection, but apparently it's not enough...

Years ago someone gave me one of these Google DIY kits that I had zero use for at that point since I didn't have a spare #RaspberryPi and having an Alexa-type device was never my cup of tea: https://aiyprojects.withgoogle.com/voice-v1/

However, since I'm all #Esp32'ing now and looking for stuff to hook up to them, I took another look at the kit and got interested in the microphone hat. Looking around online I found someone had gotten the pinouts of the 5-wire cable, so it was just a matter of connecting it to the right parts one of my #S2 #mini boards.

The #Wemos #S2Mini has the whole I2S thing going on, so I just had to find some good code examples to see if this little board worked.

After some fiddling about, I got that little guy recording to a WAV file to its #SPIFFS file system and hosting a web server so I could download the audio.

The volume is a little low, but it's pretty cool.

However, my idea behind this isn't to record audio but to be a noise detection board that will activate at a specific threshold of sound and do something.

What it will do I have no idea. Maybe use it as an alternate method for detecting if the washing machine is still going.

I am addicted to these little boards. Help.

My Wemos ESP32+SHT30 sensor bundle is reallly sensitive to how it's placed - when placed horizontally, the microcontroller heats up the temperature sensor above it.

When placed vertically, allowing convection to carry the heat away, it's ~1.5°C colder.

The best would be to have the sensor far away from the ESP32 but that defeats my minimalism goal.

I love the #Wemos product line, but I might have made a little oopsie here - the original sensor boards were made for #esp8266 , but I was greedy and went with the #esp32 model.

Now I'm looking at the pinout and it doesn't match, but hopefully it's "just" going to be a config change.

Thanks @jeffeb3! Your case works with the Wemos Lolin S2 Mini too! This is an awesome little print. It's perfect for adding a bit of LED diffuser (printer paper in my case) and protecting the boards when I toss them in my bag

I spent the afternoon building a little temp sensor for my #homelab using a #ESP8266 #Wemos D1 mini and #BMP280 temp sensor. #ESPHome made it a breeze to get the board configured and pushing data to #Influxdb so I could chart it in #grafana.

Eventually I'd like to get this running off a #LiFePO4 battery, and maybe onto a PCB. Would love to have these all over the house.

How hot does your homelab run?

I use #PlatformIO in #vscode to build applications for #ESP32, #ESP8266, #Wemos D1 Mini Pro etc. Would like to connect with other experienced IoT developers to exchange ideas with.

My electronics skills are basic but sufficient (for now).
