so the shock collars work at 433MHz, how vulnerable do you think theyd be to an rf spam attack from a flipper zero

No clue. Look what others have found! The Tesla frequency is 315 MHz in the US & 433MHZ in the UK.

My finished project: APRS iGate.

APRS LoRa iGate from Heltec with BME280 module, temperature, humidity and atmospheric pressure sensors.
433MHz, 100mW.

Ah, despite the IC being perfectly happy at 915MHz and the board being advertised as 433/915, it's got a 433MHz filtering network on it. Explains a lot

433mhz is the transmission signal.

Battery is lithium ion, prone to over heating.

2 remote options right there.

A high-power laser pointer, capable of starting bonfires, will overheat a black housing at night.

Flipper Zero can interupt 433mhz.

Mal eine Frage in die Runde. Wie erklärt man jemanden, der keine Erklärung will, die Funktionsweise der 433MHz Fernbedienungen und das es zu Überraschungen kommen kann, wenn jemand neu ins Nachbarhaus eingezogen ist?

It all needs to be put on connectors and soldered... but we have a housing! In the top right under the 433MHz radio module is the shocker btw, it's now fully integrated :3 electrodes come out of the box via grommets. Will have electrodes built tomorrow.

Sending and decoding a 433MHz signal with an ESP32, a CC1101 and Universal Radio Hacker

In this blog post, I write about how my attempts to send and decode a binary message over 433MHz

also if you look at MHz numbers for antennas and are confused what you need, the best basic reference:

915mhz - America
433mhz - Europe

i think the plan with the openshock hub is that ill mount the esp32 on protoboard and then add the 433MHz rf transmitter and receiver and then slowly add functionality with extra radios/buttons/screen/battery over time. then itll just be a decently cheap custom SDR.

Dipping a toe into SDR (software defined radio) just slightly, out of curiousity.
Checked out the 433MHz band yesterday and saw a sensor send out temp and humidity.
High levels of “no idea what I am doing” but fun to learn about stuff like this at a slow pace.

Mistä lapasesta? 😆 Oikealta 23cm (1200MHz), 2 x 70cm (433MHz), 2m (144MHz), 4m (70MHz) ja uusimpana modifioitu 6m (50MHz). 6m ja 23cm:iin pitää vielä tehdä antennit, muutoin täysin toimivat 25-35W vekottimet kaikenlaiseen yhteydenpitoon ☺️
April 13, 2025 at 8:21 PM
anyone have any fun modules for an esp32? current list for additions on top of the 433MHz rf is extra radios, screen + input, and a battery, but dunno what else to do
August 29, 2025 at 3:53 PM
ENTÃO, pior que o 2º modelo do Celeron 300mhz era tão mais parrudo que os caras descobriram que mexendo na bus dava pra subir pra 433mhz sem problemas

Probando @tinygs.bsky.social en una placa Heltec LoRa ESP32 433MHz con antena incorporada , más sencillo, compacto y barato imposible.
December 29, 2025 at 10:29 AM
5GHz und 40MHz gleich mit! Ach was! 433MHz und 866MHz ebenfalls!
September 28, 2025 at 7:04 PM
Il n'y a aucune télécommande de vibro qui fonctionne sur la fréquence des 433Mhz. OWNED !!!
August 23, 2026 at 6:19 PM
anyone have any embedded development projects for an esp32 with a 433MHz transceiver other than an openshock hub in case the electronics stuff gets here before the shock collars?
August 28, 2025 at 11:45 PM
Doing some experiments with #meshcore on #433MHz
A drive test shows very good results.
Heltec v3 as companion and lily as repeater.
At 2km distance still 10dB report.
