Stalker-RFM

This is a repository for a multiple device for a Stalker-RFM project

Main goal was buid a long range localizator based on RadioFrequiency signal strength, to make a Stalker Echo detector replica, which actually can search for anomalies with a (With a reciever module) for an Airsoft LARP.

Within this project we have created 3 working device:

• Stalker Echo detector

https://www.thingiverse.com/thing:6482542

• Plant anomaly

• Bomb anomaly

https://www.thingiverse.com/thing:6482546

The echo detector can detect signals streght from the Plant & bomb over 100m (originally expectation was 1km in the forest, but we are not able the achive this distance) Echo detector can show the signal strength on the olded display and/or can show the strentgh based on flashes

Main HW's

• RFM module: RFM69HW MCU:
• Echo and bomb: Nodemcu Esp32
• Plant: Bluepill (CKS32F103-MS)

BOM: https://docs.google.com/spreadsheets/d/1qDEaFcn8x45I9WfJCfd5FSGOwXvvdaZVDlj4wth8O7k/edit?usp=sharing

Echo detector features:

• Can detect and show 433mh signals strenght from the plant, and bomb.
• Battery powered, and can charge via USB-C
• OTA flash
• Feedback for singal recivering: Buzzer, LED, Oled
• Buttons to configure RFM parameters
• Battery Display

Bomb features:

• Normally sending 433mh signals
• 4x18650 battery and Battery display
• Radio active noise making with a buzzer
• ARGB leds for flashing, and fading
• Acceleromter
• Accelerometer can activate the bomb --> flashing and counter can start (cannot be explode)
• Once's activated it can deactivate with a deactivation process based on multiple deactiavtion sheet.

Plant Feature:

• Normally sending 433mh signals
• 18650 battery and Battery display
• Led

Main Folders:

• Stalker-RFM\VisualStudioCodes\StalkerEchoDetector
• VisualStudioCodes\StalkerFAB-100_Bomb
• VisualStudioCodes\STM32_AnomalyModule

The rest of them is just experimatal code for different micros or usefull code, which i wanted to save:

• Brain-RFM69HW-Reciever-WIP
• Brain-RFM69HW-Sender-WIP
• RFM_LowPowerLab_Bluepill_Sender
• RFM_LowPowerLab_ESP32_Reciever
• RFM_LowPowerLab_ESP32_Sender
• WaterLevelDetector
