#wasfehlt: Der elektronische Hundeabstandshalter

Der Hund von Aleks hat einen Erzfeind, eine Dänische Dogge, die in der direkten Nachbarschaft lebt. Beide Hunde sind große, starke, unkastrierte Rüden und in ihrer Wut nur schwer zu halten, wenn sie sich draußen begegnen. Die Menschen, die zur Dogge gehören, haben zwar eigentlich auch ein Interesse daran, dass die beiden sich aus dem Weg gehen, nehmen das Thema aber nicht so richtig ernst. Sie kündigen an "wir gehen nur zu den und den Zeiten raus", halten sich dann aber nicht dran, weil sie meinen, dass nur mal kurz zum Laden gehen ja nicht zählt. Eine Aufteilung des Dorfs in zwei Reviere ist auch keine Option, die beiden Hunde leben nebeneinander an einem Ende des Dorfs.

Ich muss zugeben, dass Bunny hier eher Täter ist als Opfer. Er hat angefangen (weil er zuerst da war und findet, dass dieses Revier ihm gehört) und die Dogge ist sicher ansonsten ein ganz lieber Hund. Ich verstehe schon, dass die Doggenfamilie da der Meinung ist, sie müssten sich nicht kümmern, sondern wir. Aber ohne Kooperation geht das schlecht.

Nach einem Jahr des Doggenterrors denke ich: Vielleicht gibt es ja eine technische Lösung. Mit Hilfe von ChatGPT, meinem Bruder und dem Techniktagebuch-Chat recherchiere ich, ob man herausfinden kann, wann die Dogge draußen unterwegs ist.

Esther Seyffarth schlägt einen Spaziermeldeknopf vor, den jeder Hund drückt. Aber ich glaube nicht an Lösungen, in denen "da müssen alle dran denken, und zwar jedes Mal" vorkommt.

Nächster Vorschlag von Esther: "Der Haustürschlüssel muss einen RFID-Chip bekommen und an einem Schlüsselbrett mit RFID-Leser aufbewahrt werden und sobald der Schlüssel entfernt wird, sendet der angeschlossene Raspberry Pi eine 'wir sind draußen' Nachricht an Bunny via Telegram. Aber Moment, dann könntet ihr ja auch nicht raus wenn die Leute einfach mal ohne Hund zum Bäcker gehen oder den Müll rausbringen."

Außerdem müssten sie dann den Raspberry immer angeschlossen lassen und sich um sein Funktionieren kümmern. Wir brauchen was Kooperationsfreies. In anderen Worten: Was Illegales, Unethisches und Privatsphärenverletzendes.

Nach Beratung durch ChatGPT und meinen Bruder probiere ich Folgendes aus: Ich installiere ein Ding namens Aircrack-ng und noch ein paar andere Sachen, die irgendwie dazugehören. ChatGPT gibt mir ein kleines Pythonscript. Damit kann ich von meinem Laptop aus die MAC-Adressen aller Geräte sehen, die sich in der Nähe befinden. Das geht, wenn auf den Geräten WLAN eingeschaltet ist, weil sie dann ständig in der Gegend herumtasten auf der Suche nach einem WLAN, und dabei ihre individuelle Gerätekennung übermitteln. Das Pythonscript sieht zwar vor, dass man diese MAC-Adressen nur verschlüsselt, also sowas-wie-anonymisiert zu sehen bekommt. Man kann diesen Teil aber einfach auskommentieren, dann sieht man die MAC-Adressen aller Geräte. Das Ganze klappt nicht auf Anhieb, aber ChatGPT ist sehr hilfreich beim Debuggen, und nach ein, zwei Stunden läuft es.

Ich bin gerade nicht in Schottland, aber wenn ich dort wäre, würde ich jetzt am Fenster warten, bis die Dogge vorbeikommt, und dann nachsehen, welche MAC-Adresse das Handy hatte, das da gerade mit vorbeigegangen ist. In der Annahme, dass es sich um das Handy des Doggenbesitzers handelt und auf diesem Handy WLAN immer eingeschaltet ist, so wie auf meinem ja auch.

Wenn ich diese MAC-Adresse mal habe, müsste es möglich sein, draußen festzustellen, ob das zur Dogge gehörende Handy in unserer Nähe ist. Leider erst dann, wenn es 20 bis 100 Meter entfernt ist, aber besser als nichts. Dazu bräuchte ich eine portablere Lösung, ich will ja nicht den Laptop mit rausnehmen, aber über die plane ich dann nachzudenken, wenn es so weit ist.

Mein Bruder meint: "Vermutlich hat die Hundenase höhere Reichweite. Aber ein bisschen müsste man mit einer WLAN Antenne was erreichen. Wenn es dann ein Raspberry mit WLAN-Adapter mit Antenne ist, könnte es besser funktionieren." Ich sehe uns schon mit einer meterhohen Kalter-Krieg-Installation draußen herumlaufen.

Im Techniktagebuch-Chat meint Esther: "Schöner wäre eine Lösung, die zwar die anderen völlig passiv bleiben lässt, mit der sie aber trotzdem einverstanden sind und die nicht hinter ihrem Rücken stattfindet. Dann müssen sie nicht aktiv kooperieren, aber es wäre trotzdem nicht unethisch."

Gleichzeitig sagen mir Mia Culpa und mein Gewissen, dass es so wirklich nicht geht. Bestimmt denken alle Stalker von sich, dass ihr Stalken ja irgendwie durch die Umstände legitimiert ist.

Deshalb verwerfe ich den Plan wieder und schlage Aleks vor, dass er der Doggenfamilie einen GPS-Hundetracker kauft und das dazugehörige Monatsabo bezahlt (so 5-10 Euro im Monat), unter der Bedingung, dass er den Hund auch damit orten darf. Aber das will er nicht, weil er nicht glaubt, dass die Motivation im Doggenhaushalt groß genug ist, dass sie den Tracker dann auch wirklich immer am Hund haben und aufladen (obwohl sie den Hund, falls er verlorengeht, selbst damit orten könnten).

Thomas Jungbluth schlägt vor: "Wenn es ein Apple-Haushalt ist, könnte man auch die AirTracker in einem entsprechenden Hundehalsband nehmen, die integrieren sich etwas aufwandsgeringer in die elektronische Infrastruktur (die Woist-App hat jeder auf seinem Gerät). Akkudauer laut Apple ein Jahr."

Kirsten Schelper ist derselben Meinung: "Ein kleines AirIrgendwas am Halsband (der Dogge) würde ich für am vielversprechendsten halten. Die echten GPS Tracker sind vergleichsweise riesig, ich denke die landen schnell in der Ecke. Und der Akku hält nicht lange. Ein kleines AirIrgendwas, das klein und unauffällig ist, bleibt am Halsband, weil keiner mehr dran denkt, dass es da ist."

Aber der Haushalt von Aleks ist kein Apple-Haushalt. Außerdem updaten die AirTags ihren Standort wohl eher selten. Beim Hundeerzfeind sind wir aber auf einen präzisen und aktuellen Standort angewiesen. Ich fürchte, das verträgt sich einfach nicht mit einem Jahr Batterielaufzeit. Und dann funktionieren AirTags nur dadurch, dass sich möglichst viele iPhones um das AirTag herum befinden, die das Signal weitergeben. Die Hunde leben in einem nicht sehr bewohnten Dorf, die Handydichte ist also gering und die iPhone-Dichte sicher noch viel geringer.

Unsere Diskussion gerät wieder aufs unethische Gelände, Drohnen und versteckte CCTV-Kameras werden diskutiert. Aber ich fürchte, das ist noch schlimmer als mein verworfener MAC-Adressen-Erfassungsplan.

Die Suche bleibt ergebnislos. Naja, jedenfalls weiß ich dadurch jetzt, wie ich an meinem Laptop die MAC-Adressen aller vorbeikommenden Geräte erfassen, anzeigen und speichern kann. In der Folge suche ich eine Weile nach einer Lösung, wie ich bei meinem eigenen Handy WLAN automatisch ausschalten kann, wenn ich nicht zu Hause bin. Weil man damit nämlich allen im Umkreis einer WLAN-Reichweite ums eigene Handy herum "Hallo! Hier kommt Kathrin!" sagt. Obwohl ich angenommen hätte, dass das zu den Standardfunktionen von Android gehört oder es wenigstens 35 verschiedene Apps dafür gibt, finde ich nichts.

Im Redaktionschat kündige ich an: "Ich schreibe dann irgendwann die ganzen nichtfunktionierenden Lösungen auf, damit ich auf den Beitrag verweisen kann, wenn es in zehn Jahren eine selbstverständliche, ganz einfache, privatsphärenschonende Lösung für genau dieses Problem gibt, eine Art elektronischen Hundeabstandshalter. Mit energy harvesting aus dem Hund natürlich, so dass man nie den Akku laden muss. Eigentlich müsste sich aus Bunnys Reißen an der Leine eine sehr große Menge Energie gewinnen lassen."

Einige Tage nach dieser Lösungssuche richtet Aleks eine WhatsApp-Gruppe für sich und den Doggenbesitzer ein. Sie legen Rausgeh-Zeitslots für beide Hunde fest und benutzen WhatsApp, um sich bei Ausnahmen abzusprechen. Seitdem herrscht Frieden.

Hello! 😊 How can I help you today?

Du:

ich möchte ein IOT Fahrradparken System bauen, HAMBURGERHUB.net Die Nutzer können ihre Räder an fest verankerten Abschlussstationen (angeschlossen an Fahrradbügeln) mit dem Smartphone anschliessen, und wieder lösen.. Keine tragbaren Schlösser mehr. Meine Frage, ich kann mir die Software auf dem Telefon noch halb vorstellen, aber wie programmiert man die Schlösser selber, oder wie nennt man diesen Bereich?

ChatGPT:

Das klingt nach einer spannenden und zukunftsorientierten Idee! 🚲🔐 Ein IoT Fahrradparksystem wie dein HAMBURGERHUB.net fällt in den Bereich Embedded Systems, Mikrocontroller-Programmierung, und IoT-Hardwareentwicklung. Hier ein Überblick über die wichtigsten Themen und wie du loslegen kannst:

🔧 Der technische Bereich heißt:

Embedded Systems / Embedded Programming

IoT (Internet of Things) Development

Hardware-nahe Programmierung

Smart Lock Systems

Firmware Development

🧠 Wie man „die Schlösser“ programmiert – Schritt für Schritt:

1. Hardware auswählen

Typische Komponenten für dein Projekt:

Mikrocontroller: z. B. ESP32 (mit WLAN & Bluetooth)

Elektromechanisches Schloss (z. B. Solenoid-Lock oder Motorized Lock)

Stromversorgung: Netzteil oder Akku + Solar

Sensorik: z. B. Reed-Switch oder Hallsensor zur Erkennung ob abgeschlossen/offen

2. Schlosssteuerung programmieren

Die Logik liegt auf dem Mikrocontroller:

Öffnen/Schließen des Schlosses

Kommunikation mit dem Server oder dem Smartphone

Sicherheitsmechanismen (z. B. Authentifizierung)

👉 Programmiersprachen: meist C/C++ (für die Firmware), alternativ MicroPython

3. Kommunikation mit dem Smartphone

Optionen:

Bluetooth Low Energy (BLE): Smartphone ↔ Schloss direkt

WLAN + Cloud API: Schloss ↔ Server ↔ App

NFC/RFID optional: für kontaktloses Entsperren

4. App & Backend

Smartphone-App (iOS & Android): Steuerung & Verwaltung der Schlösser

Backend-Server/API: Registrierung, Reservierung, Freigabe der Schlösser

Security Layer: Verschlüsselung, Tokens, Nutzerverwaltung

📚 Was du dir anschauen solltest:

ThemaTechnologienHardwareESP32, Arduino, Raspberry Pi, LoRa, Solenoid LocksSoftwareArduino IDE, PlatformIO, MQTT, REST APIsKommunikationBLE, WiFi, MQTT, HTTPSCloudFirebase, AWS IoT, Azure IoT HubAppReact Native, Flutter, native iOS/AndroidSicherheitJWT Tokens, TLS, OAuth2

🧰 Erste konkrete Schritte:

ESP32 Dev Kit kaufen (~10 €)

12V Solenoid Lock besorgen

Erste Prototyp-Schaltung bauen (ESP32 → Relais → Schloss)

Schloss über Bluetooth mit Handy entsperren (z. B. via App oder WebApp)

Optional: Backend in Node.js oder Python Flask aufsetzen

Wenn du magst, helfe ich dir beim Einstieg mit einem ersten Beispielcode für das Öffnen eines Schlosses via Bluetooth. Möchtest du lieber mit Bluetooth starten oder direkt über WLAN & Server?

Und willst du die Stationen auch mit Solarstrom betreiben oder lieber per Netzanschluss?

Du:

Ist das dann ein 'Projekt', oder würde das industrial auch so gemacht?

ChatGPT:

Sehr gute Frage – und sehr klug gestellt. Kurz gesagt: Ja, das ist ein Projekt – aber eines, das man auch industrial bauen kann. Die Herangehensweise ist nur etwas anders:

👨‍🔬 Prototyping (Maker / Projektphase)

Du baust erst mal einen funktionierenden Prototyp – zum Testen von:

Idee & Benutzungsablauf

Kommunikation (Smartphone ↔ Schloss)

Sicherheit & Zuverlässigkeit

Mechanik & Integration in reale Fahrradbügel

Das läuft mit:

Entwicklungsboards (z. B. ESP32 DevKit)

fertigen Modulen (Relais, Sensoren)

einfacher Stromversorgung

3D-gedruckten oder handgefertigten Gehäusen

➡️ Diese Phase nennt man auch Proof of Concept (PoC).

🏭 Industrialisierung (Produktionsreife)

Wenn dein Prototyp überzeugt, beginnt die Produktentwicklung. Dann passiert Folgendes:

1. Hardware-Redesign

Eigene Platinen (PCB) werden entworfen (z. B. mit KiCad oder Altium)

Bauteile werden industrietauglich ausgewählt (IP65, vandalismussicher)

Gehäuse wird professionell designt & spritzgegossen (statt 3D-Druck)

2. Firmware stabil & updatefähig

Sichere Over-the-Air (OTA) Updates

Logging, Fehlermeldung, Debugging über Cloud

Watchdog-Mechanismen für Dauerbetrieb

3. Zertifizierung

EMV (elektromagnetische Verträglichkeit)

CE-Kennzeichnung, evtl. RoHS, RED

4. Produktion & Skalierung

Stückzahlen planen, Lieferanten finden

Langlebige Energieversorgung (z. B. Solar + Akku mit Power Management)

Backend skalieren (Last, Datenbank, Sicherheit)

✅ Fazit:

Dein DIY-Projekt ist der Anfang.

Die Industrie würde das Prinzip übernehmen, aber mit robusteren Bauteilen, sauberem PCB-Design und standardisierten Prozessen.

Viele Start-ups (z. B. Tier, Donkey Republic oder auch die Deutsche Bahn mit Call-a-Bike) haben genauso angefangen – mit Prototypen aus Arduino & ESP32, dann erst in Serie gegangen.

Wenn du willst, kann ich dir einen Roadmap-Plan machen:

Von Idee → Prototyp → Pilotphase → Industrieprodukt Oder ich helfe dir beim Aufbau eines konkreten Schloss-Demos mit Code & Bauteilliste.

Was möchtest du als Nächstes machen?

Du:

[ad_1] RFID cards and tags are everywhere! We use them in buildings for access control. Printers and photocopiers can use them to identify staff members. Livestock tagging and pet identification tags all use a form of RFID. The tech to read an RFID device is cheap, for around $5 you can get the reader, and for $4, a Raspberry Pi Pico can read the IDs from the cards / tags.In this how to, we will learn how to read RFID tags and cards using an MFRC522 reader and a Raspberry Pi Pico, the goal will be to create a fictional RFID access control system that will allow users into a building, or alert security to remove them. Before we can do that, we need to identify the ID of our cards / tags. The first section of this how to will do just that, and then we will insert some code to control two LEDs to simulate the locking mechanism.For this how to you will needRaspberry Pi Pico running MicroPythonMFRC522 RFID readerLarge breadboard11 x Male to male jumper wiresGreen LEDRed LED2 x 100 Ohm resistors (Brown - Black - Brown - Gold)Building the Hardware(Image credit: Tom's Hardware)The hardware build is split into two sections.

The module, pico-rfid is from friend of Tom’s Hardware, Kevin McAleer, and is based on the work of Danjperron.1. Connect your Raspberry Pi Pico to your computer, and open Thonny. We assume that you already know how to set up your Raspberry Pi Pico. If not, we have this handy guide.Get Tom's Hardware's best news and in-depth reviews, straight to your inbox.2. Create a new blank file and copy the contents of this link into the blank file. Then save it to the Raspberry Pi Pico as mfrc522.py. This is the Python module / library that will enable our code to talk to the RFID reader.Writing the Project CodeWith all the setup complete, we now get down to coding the project. For this we will again use Thonny, and write code to check the ID of any RFID card presented to the reader. For this first part, we will need to make a note of the ID, as we will later use it with a conditional test that checks if the ID matches a hard coded value, then it will allow entry. If not, then we will get an ACCESS DENIED message.1. Create a new blank file in Thonny.2. Import three modules (libraries) for using the MFRC522 RFID reader, controlling the pace of the code, and for using the GPIO.from mfrc522 import MFRC522 import utime from machine import Pin3. Create an object, reader, to tell the code where the RFID reader is connected.reader = MFRC522(spi_id=0,sck=2,miso=4,mosi=3,cs=1,rst=0)4. Create two objects for the red and green LEDs, telling the code where the LEDs are connected and that they are output devices that we want to send current to.red = Pin(14, Pin.OUT) green = Pin(15, Pin.OUT)5. Write a short message to the user, instructing them to present the card to the reader. The “\n” is Python’s syntax to introduce a new line at the end of the print() function.print("Present the card to the reader\n")6. Create a list called “PreviousCard” and store the value zero inside of it. We’ll use this list later to store the current card ID.PreviousCard = [0]7. Create a while True loop to continually run the code within it.while True:8. Initialize the reader so that it is ready for use. reader.init()9. Create a tuple to store the reader status and the RFID tag type. (stat, tag_type) = reader.request(reader.REQIDL)10. An if conditional will read the contents of the card if the reader is ready. Then it will update the stat and uid objects with details from the card. if stat == reader.OK: (stat, uid) = reader.SelectTagSN()11. If the uid of the card is the same as the value stored in the PreviousCard object, then the code will continue. This will happen when the same card is repeatedly shown to the reader. if uid == PreviousCard: continue12. Create an if conditional statement to check that the card read was ok. if stat == reader.OK:13. Print a message to the user, and then store the card’s UID to an object called “card”. Then print the card details to the Python shell. print("The card details are as follows") card = reader.tohexstring(uid) print(card) 14. Update the PreviousCard object with the uid of the presented card. PreviousCard = uid15. Create an else condition which will run when no cards are presented. Updating the PreviousCard object. Then add a 50ms pause to the code before the main loop repeats. else: PreviousCard=[0] utime.sleep_ms(50)16. Save the code to the Raspberry Pi Pico as reader.py and then click on Run >> Run Current Script (or press the green play button). Follow the instructions and present the RFID card / tag to the reader. 17. Copy the entire card details, this is the uid of the RFID card and we will need that for the next part of this how to. The uid looks something like this, yours will be different.[0x04, 0xBC, 0xA0, 0x9A, 0xB3, 0x43, 0x80]Complete Code Listingfrom mfrc522 import MFRC522 import utime from machine import Pin reader = MFRC522(spi_id=0,sck=2,miso=4,mosi=3,cs=1,rst=0) red = Pin(14, Pin.OUT) green = Pin(15, Pin.OUT) print("Present the card to the reader\n") PreviousCard = [0] while True: reader.init() (stat, tag_type) = reader.request(reader.REQIDL) if stat == reader.OK: (stat, uid) = reader.SelectTagSN() if uid == PreviousCard: continue if stat == reader.OK: print("The card details are as follows") card = reader.tohexstring(uid) print(card) PreviousCard = uid else: PreviousCard=[0] utime.sleep_ms(50) We’ve got the code, now we need to tell the project code that we want to use that code to give us access, and to light up the green LED. If another card / tag is presented to the reader, then the red LED will light up.1. Between these two lines, create new lines of code. print(card) NEWCODE GOES HERE PreviousCard = uid2. Create an if condition that checks for your card’s uid. Note that it looks like a Python list, but in reality it is stored as a string, so we need to wrap the value in “ “. Don’t forget the [ ] brackets. if card == "[0x04, 0xBC, 0xA0, 0x9A, 0xB3, 0x43, 0x80]":3. If the value stored in the card object matches the hard coded value, print “ACCESS GRANTED” to the Python shell. print("ACCESS GRANTED")4. Create a for loop to toggle the green LED on / off ten times., with a 0.1 second gap between each change of state. Turn the green LED off at the end of the for loop. for i in range(10): green.toggle() utime.sleep(0.1) green.off()5. Use an else condition for when an unrecognized card / tag is presented to the reader. This will toggle the red LED on and off just like the green LED. else: print("ACCESS DENIED") for i in range(10): red.toggle() utime.sleep(0.1) red.off()6 .Save the code as reader.py to the Raspberry Pi Pico. Click on Run >> Run Current Script (or press the green play button). Follow the instructions and present the RFID card / tag to the reader. If the card is correct, then the green LED will flash and the Python shell will print “ACCESS GRANTED”. Try another RFID card / tag, this should make the red LED light up, and the Python shell will print “ACCESS DENIED”Complete Code Listingfrom mfrc522 import MFRC522 import utime from machine import Pin reader = MFRC522(spi_id=0,sck=2,miso=4,mosi=3,cs=1,rst=0) red = Pin(14, Pin.OUT) green = Pin(15, Pin.OUT) print("Present the card to the reader\n") PreviousCard = [0] while True: reader.init() (stat, tag_type) = reader.request(reader.REQIDL) if stat == reader.OK: (stat, uid) = reader.SelectTagSN() if uid == PreviousCard: continue if stat == reader.OK: print("The card details are as follows") card = reader.tohexstring(uid) print(card) if card == "[0x04, 0xBC, 0xA0, 0x9A, 0xB3, 0x43, 0x80]": print("ACCESS GRANTED") for i in range(10): green.toggle() utime.sleep(0.1) green.off() else: print("ACCESS DENIED") for i in range(10): red.toggle() utime.sleep(0.1) red.off() PreviousCard = uid else: PreviousCard=[0] utime.sleep_ms(50) [ad_2] Source link
