Ever needed to tri-state an #esphome GPIO?

HIGH and LOW not enough for your projects?

Need a bit of high-Z or dual-use the pin as Input?

Here's my solution:

Da wir unterschiedliche Spielarten der BMx280-Sensoren im Labor haben, ist die Verwirrung bei Anschluss, Treiberwahl und Adressierung groß - daher hier ein kleines Tutorial, was die unterschiedlichen Varianten und Anschlussweisen beleuchtet. #BME280 #BMP280 #Arduino #ESP32 #ESP8266 #NodeMCU #informatikEdu https://oer-informatik.de/esp_bme280

So I'm still investigating the connectivity issues I witnessed with #rc2014bbs and here are my current findings:

1.) while the telnet listener of the #Zimodem firmware is no longer open on port 2014, the #wifi of the #esp8266 itself is still active and the reserved ip is responding to ping requests.

2.) once the firmware gets reset via ATZ it sometimes restarts /re-opens the listener on port 2014

3.) the listener dies a few hours after initial powerup of the system

4.) my memory may be failing me but those issues began somewhere around autumn last year when I updated the firmware to version 3.7.1

As a result of these findings, I have reverted the firmware on the esp8266 to Zimodem version 3.6.5. It's not an official release - I checked it out using the corresponding commit hash.

The BBS was powered up with that version yesterday at 09:00 am and it is still running about 24 hours later, which was never the case with the 3.7.1 version of the firmware. I've also noticed a few other glitches not being present with the 3.6.5 version.

It is still a little too soon to call the problem solved, but there's movement here.

Also keep in mind that RC-BOX BBS (the world's first and - currently - only #rc2014 based #bbs) is using a wifi connection so other sources of influence may also have an effect on connectivity (although they never were *that* worse before 3.7.1).

Ich wollte ein bisschen Farbe in meinem Gaming Room und habe dafür ein paar einfache Komponenten zusammengeworfen:

Has anyone out there in Fedi-world ever used the #Sipeed M1s DOCK (I don't know why it's in all-caps but it is) dev board?

I bought a couple of them because they were cheap, and now naturally I need to decide what to do with them.

They are orders of magnitude more powerful than my usual go-to, the #ESP8266. Supposedly, they will even run 'real' Linux.

They use the Bouffalo Labs BL808, so it looks like this is the SDK?

Any tips, ideas, success stories?

ESPHome is absolutely incredible!

Took one of the many ESP8266 boards I still had lying around, quickly did some soldering and got a nice extensible base to control some cheap LED fairy lights! They are normally battery powered, but that's boring

I even did things properly this time with an extra voltage regulator and transistor so as not to overload the ESP, current wise.

Put into HomeAssistant, and voila! My partner has some cozy lights that she can easily turn on and off :3

Yay! I have written a build guide for my #3dprintable DIY plug-in temperature and humidity sensor, go check it out on my blog!

Hey! You may have seen my #electronics videos on Hackster.io - or various #robots, including my shoulder owl Archimedes & other #CompanionBots; my Ouija #ESP8266 planchette PCB; or the Companion Core...

Or seen me in Make:, Hackaday, HackSpace mag, the Adafruit blog, TWiT, Recomendo, etc.

As I make new project threads, I'll link them below :D

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.

New revision of #MegaWiFi hardware, now featuring a #RISC_V #ESP32C3 instead of the old #ESP8266, and up to 64 Megabit (8 MiB) ROM support with linear addressing via the "VA22 -> #CART" hack!

In the spirit of doing something new every day, I’ve dug out old #NodeMCU #ESP8266 and started playing with #ESPHome. Despite initial difficulties with connecting it to a hidden WiFi (it’s not that obvious!), it actually worked and I can’t believe how easy it was to connect it and report temperature and humidity from #DHT11 sensor to #HomeAssistant.

I guess the real party trick is to build it to be in a usable form, with a thought out layout and in a case…

I guess I need a 3D printer now…
