So, today I made a many years old, maybe a little childish wish come true.
This cute little fella is a #esp01 controlling a LED strip with SMD5050 RGB modules.
Its not the addressable WS28XX, so I have only one color, but thats fine.
This is a #IoT thing, I always wanted to build and I'm so happy, that I finally made it :awesome:

A open, black case holding electronics.
In focus, a ESP-01 is mounted on a breakout bord. From left, a white cable is connected into the box, where a red light is indicating power and a blue light on ESP-01 is indicating action.
Wires are leaving the box to the right, where they are connedted to a bright shining LED stripe.

I understand you can flash #micropython onto an #esp01 module, would that give better wifi functionality to a #pipico? By better I mean using the AT commands seems rather painful & I am hoping to find a better/faster solution that feels more like how it does on a picow when u import network and socket.

I assume flashing micropython directly to the esp01 is really just to use it as a simple micro controller, and not a wifi connectivity upgrade?

Myös ESP-01:n kahden releen moduuli on suunniteltu huonosti: molemmat releet naksuvat käynnistyksen yhteydessä. Uudelleenohjasin GPIO:t niin, että ei naksu, GPIO2 -> GPIO1 ja GPIO0 -> GPIO3. #elektroniikka #esp01 #esp8266

I really hate breadboards and the most, the wires - they are everywhere!
So after it seemed to worked on breadboard, I now soldered my first prototype of my idea having a #ESP01 with a #HD44780 as network display.
It was kind of difficult to get the right #LiquidCrystal_I2C, since its years old and doesnt work with later modules. And now: lets do some coding!

#IoT #ESP8266 #tinkering

A very dark picture of a bright shining LCD display saying "Hello, World!". Many wires connect the LCD with a level shifter a ESP01 is connected to from the other side and a step-down module with USB. Beside there is soldering wire and a pincers. All is laying on a heat resistent soldering pad

Have to confess, the instant glue won this time (#AMS1117 is not straight), but anyway I'm really happy with the outcome. First I had concerns that the #ESP01 is too high on the breakout-module, so it gets to tight with the button, but it worked out.

#ESP8266 #IoT #Button

Inside the push button.
You see a ESP01 module in focus. Beneath you can see a AMS1117 step-down-module and a USB port, both glued to the bottom. In the background some wires in red, green and black leave the picture

A picture of the actual "front-end" of the button. You see a black box with a red LED overhead. Instead of only parts, you can see the whole LED.
Beneath there is a blue square rotated by about 45°, so edges are pointed to the flat sides of the rectangular box

When the button is pushed, the #ESP01 connects WiFi, while blinking slowly the LED. When connected, the POST is sent to server, the LED lights constant in the meantime.
In the gif it has no error (yeah!), but if server response with a error code or response contains errors, the LED flashes way faster.
It reminds me of #RickAndMorty|s butter robot. Nice little helper, that spares me some clicks while looking a little ridiculous :)

Notes on Landis+Gyr Power Meters

Sometimes it’s worthwhile keeping notes about stuff that didn’t work. This is one of those times.(...)

Ah! Winter is there. Who was the idiot, who thought that he lives on the sun?
`
if (isnan(temp) || temp < (float)0)
Serial.println("Failed to read from W-1 sensor!");
`
Yes. Its me. Heading to get the #ESP01 module for a small software update....

This is the first one, where I actually used glue. I'm kind of proud, how tidy this looks. The #ESP01 is the only part I can take out for programming. This really could be a template for a rebuild of my other sensors.

A ESP-01 based temperature sensor. The DS18B20 is external stored in silver case left above. Inside parts of the breakout board are visible including some wires. On top of it a ESP-01 is placed. The board has label for the the pins.
On the upper right there is a micro-USB port glued to the side. Almost not visible the step-down module which is glued to side below as well.

Felt weird having this so stuffed using a #ESP01 specific board with a #DHT11 sensor.
Using a #AMS1117 and a naked #ds18b20 requires me to have pin connectors to prevent soldering on the board itself but looks better to me

So far so good. I actually found something in the shop and so the first aproach gets a USB power supply using #LM2596

I drilled some holes into the box but my problem with at least 2 dregree too much, remains unfortunately.

#esp01 #esp8266 #diy

The inside of the prototype box contains a step down module, the ESP-01 on a sensor board and a couple of cable

It was surprisingly fast done to get this little fella #esp01 talking to my #raspberry. Now two of them are up and send #json encoded humidity and temperature.
And since hours I stuck at this #python stuff getting it right into #mysql database. Better not to start a war, but I really dont like python.
So much code, so small knowlegde...

ESP-01 module mounted on a programming interface. The power LED is on since the device is connected in flash mode

Short follow-up: one or two days ago, the battery seems to have been drained enough to stop it from working. It's voltage measured about 2.3V, so still high enough to not damage the battery. I think 5 months for one charge is a very good time.

Today's work: an ESP-01S on a soldered perfboard that will notify me when something is thrown into my mail box.
Powered by a single LiFePO4 battery.
The ESP lies in deep sleep until one of the two Reed switches is triggered. Message is sent through MQTT to my home assistant.

A soldered circuit board in a black plastic case. There's a LiFePO4 battery powering it. The LED of the ESP-01S is glowing. You can see a few resistors, capacitors, and a transistor.

Hmm, what should I do with this #esp01?

Letztens ein Gehäuse für den Programmer des #esp01 gebaut, mit #anycubic Mega 3D Drucker erstellt. Reset über an/aus, weil der Reset-Pin des ESP scheinbar nicht rausgeführt ist.
