Chikken Chekkinator

I've been working on a thing for the past few weeks to keep track of chicken chores so we dont have to ask "have you fed the chickens" all the time

Its not finished, i need to get the final art printed but i'm pretty happy with it so far. It lights up different colours depending on who did the task, it gets saved to home assistant so you can view the status remotely and get reminders, and it changes its brightness based on the time of day so its not too bright at night.

i learned so much about microprocessor programming doing this and had a lot of fun. I think i want to make more things like this for helping my ADHD brain do regular tasks

here's the (almost) final artwork that i need to print for it:

i might do a technical writeup of how it works if people are interested

DIY: Easiest Standalone Deauther

Previously, I have built a standalone Deauther with an OLED display and buttons over here, but realistically, everyone is just going to use the web interface. So, I recently found an ESP8266 ESP-07 USB module that is perfect for a standalone Deauther, since it has a USB connector built-in and you can just plug it into any powerbank. This module cost me around USD3 and you can find it in AliExpress.

First, we need to download the Deauther firmware. Go to this page and download this file: esp8266_deauther_2.6.1_DSTIKE_NODEMCU_07_V2.bin

Next, set the switch on the ESP module to "PROG" and plug it into your computer's USB. Run Google Chrome or Microsoft Edge browser and go to https://esp.huhn.me. Click CONNECT and select the USB Serial item and click Connect.

Now that it has successfully connected, click SELECT and choose the firmware file you downloaded earlier, then hit the PROGRAM button.

It should now start flashing, so just let it finish the job.

Finally, flick the switch on the ESP module from PROG to UART, and hit the reset button on the ESP module while still plugged into USB, or you can just remove it from your computer and plug it into a powerbank. On your phone/computer, just connect to the Wifi network "pwned" and use "deauther" for the password. Then open your web browser and go to http://192.168.4.1

That's it! You now have a standalone Deauther. More information about using the web interface over here. Also, realize that in most countries, there are laws against disrupting communication networks and Deauth attacks may be illegal.

ESP8266 aus dem Deep Sleep mit einem Taster wecken

Wie du einen ESP8266 aus dem Deep Sleep mithilfe von einem Taster erwecken kannst, erfährst du in diesem Beitrag.

Ich habe dir bereits im Beitrag NodeMCU – Deep Sleep des ESP8266 gezeigt, wie du einen ESP8266 in den Deep Sleep versetzt und nach einer Zeit x dieser wieder selbständig erwacht und einen Text auf der seriellen Schnittstelle ausgibt.

Wozu der deep sleep?

Der deep sleep am Mikrocontroller lohnt sich, wenn du dein Projekt an einer Batterie betreiben möchtest. Aber auch wenn du Messwerte nur alle X Minuten, Stunden etc. benötigst, dann kann der deep sleep dir nützlich sein. Wenn ein Mikrocontroller in den deep sleep versetzt wird, dann spart dieser Strom und auch wird dieser nicht unnötig betrieben, somit lebt der Baustein deutlich länger.

Benötigte Ressourcen

Für den Nachbau dieses Beitrages benötigst du: - einen Microcontroller mit ESP8266 Chip*, - USB Datenkabel - einen Taster für die Printmontage*, - einen 10 kOhm Widerstand*, - ein 400 Pin Breadboard*, - diverse Breadboardkabel* Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links. Wenn du über diese Links einkaufst, erhalte ich eine kleine Provision, die dazu beiträgt, diesen Blog zu unterstützen. Der Preis für dich bleibt dabei unverändert. Vielen Dank für deine Unterstützung!

Aufbau der Schaltung

In diesem Beitrag verwende ich den Wemos D1 Mini V4 mit USB-Schnittstelle. Dieser Mikrocontroller verfügt über den "normalen" ESP8266 Chip jedoch über eine USB-Typ-C Schnittstelle. Der Taster in dieser Schaltung wird mit dem Pin RST des Mikrocontrollers verbunden sowie per 10 kOhm PULL Up Widerstand mit 3.3V VCC. Der andere Pin des Tasters wird mit GND verbunden.

Schaltung - ESP8266, mit Taster

Programmieren - ESP8266 per Taster aus dem deep sleep erwecken

Der nachfolgende Code dient dazu, den Mikrocontroller per Tastendruck aus dem deep sleep zu erwecken. Die Codezeile in der Funktion loop wird nie erreicht, da der Mikrocontroller bereits in der Funktion setup wieder in den Tiefschlaf versetzt wird. void setup() { //beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); //setzt den Timeout auf 2000 Millisekunden Serial.setTimeout(2000); //Warten darauf das die serielle Kommunikation aufgebaut wurde while (!Serial) {} //Ausgeben der Textzeilen auf der seriellen Schnittstelle Serial.println("Juhu, hier bin ich wieder!"); //zusätzlich noch einmal die Millisekunden seit dem Start Serial.print("läuft seit "); Serial.println(millis()); //den Mikrocontroller in den deep sleep versetzen ESP.deepSleep(0); } void loop() { //diese Zeile wird nie erreicht! Serial.println("Hallo!"); } Read the full article

Understanding ESP32 Pin Configuration: A Developer's Guide

The ESP32 microcontroller has become a cornerstone of IoT development, thanks to its versatility and powerful features. One of the most crucial aspects of working with ESP32 is understanding its pin configuration and capabilities. Let's dive into the essential aspects of ESP32 pins that every developer should know.

GPIO Pins Overview

The ESP32 boasts up to 34 GPIO (General Purpose Input/Output) pins, but not all are available for use in most development boards. Some key points about ESP32 pins:

GPIO 6-11: Reserved for internal SPI flash connection

GPIO 34-39: Input-only pins with no internal pull-up/pull-down resistors

ADC Capabilities: Two 12-bit SAR ADCs, supporting 18 measurement channels

Touch Sensors: Up to 10 capacitive touch GPIOs

Special Function Pins

Several pins serve dual purposes or have specific functions:

Boot Mode Pins GPIO 0: Bootloader mode when pulled low during reset GPIO 2: Connected to on-board LED in many development boards

UART Pins GPIO 1 (TX) and GPIO 3 (RX): Default UART0 communication Often used for flashing and debugging

SPI Pins VSPI: GPIO 5 (CS), 18 (CLK), 19 (MISO), 23 (MOSI) HSPI: GPIO 14 (CLK), 12 (MISO), 13 (MOSI), 15 (CS)

Best Practices for Pin Usage

Strapping Pins Always check the strapping pin status before using GPIO 0, 2, 4, 5, 12, and 15. These pins may affect boot behavior if incorrectly configured.

Input-Only Pins When designing sensor interfaces, prefer GPIO 34-39 for analog inputs as they're input-only and less susceptible to noise.

Pull-up/Pull-down Configuration

ADC Usage ADC1: Can be used with Wi-Fi/Bluetooth active ADC2: Only available when Wi-Fi/Bluetooth is disabled

Common Pitfalls to Avoid

Don't use GPIO 6-11 in your projects as they're connected to the internal SPI flash.

Avoid using strapping pins for critical functions that can't be changed during boot.

Remember that GPIO 34-39 don't have internal pull-up/pull-down resistors.

Be cautious with voltage levels - ESP32 pins operate at 3.3V.

Conclusion

Understanding ESP32 pinout is fundamental for successful project development. By following these guidelines and best practices, you can avoid common issues and make the most of your ESP32's capabilities. Remember to always consult the official ESP32 technical reference manual for detailed specifications and updates.

DIY: Adding External Antenna to D1 Mini

I have been using a D1 Mini for Deauther on Flipper Zero, but the range with the build-in antenna was rather mediocre, so it’s time to do some modding.

Rather than soldering the antenna cable directly to the D1 Mini, I decided to solder an IPEX connector to the D1 Mini instead. This way, I can easily change different length cables as needed.

First, we need to use a blade to make cuts to the existing build-in antenna to disconnect it, as shown in the photos below. Use a multimeter to check that the connection is really severed.

Here’s how the IPEX connector should be positioned. The center pin of the connector is the signal. Apply some soldering paste to make it easier to solder and after soldering, use a multimeter to double check that everything is properly connected and nothing is shorted.

Also, just put a tiny dab of superglue to the edge of the IPEX connector that was not soldered on. This will ensure that we don’t rip out the connector when we disconnect the antenna cable.

That’s it, we’re done. It’s a fairly simply mod. Now to try it out.

From my quick tests with a 3dbi external antenna, Deauther was able to find about 3-4 times more access points. Awesome!
