Target Camera (ESP32-CAM)
A Wireless Target Camera System based off the ESP32-CAM. A combination of programming languages is used, Arduino IDE for the ESP32-CAM, Windows UWP (Visual Basic) for the client application which also uses an MJPEG library for reading the camera stream. The UWP client application displays the stream and overlays ballistic information.
Arduino – IDE code for the ESP32-CAM
- Battery Management – Read ADC (PIN 12) – Prior to WiFi initialization which ties up the ADC inputs on the board.
- Battery Management – Requires a voltage divider, please see the Altium Circuitmaker Schematic and PCB layout.
- OTA / Over The Air Updates – Partition Scheme: \”Minimal SPIFFS (1.9MB APP with OTA/190KB SPIFFS).
- SPIFFS partition is small, is primarily used to store config data and a small image file/logo file and favicon.
3D Printing – 3D Printed Parts for the ESP32-CAM Housing/Enclosure
- Main Section – Houses the ESP32-CAM and ESP32-CAM motherboard, light pipes and power switch.
- Battery Section – Houses the battery board and AA battery holder.
- Holder – Anetnna – Part is used for installing the antenna assembly.
- Holder – Nut – Part used for locating/holding the UNC nut for tripods.
- Locating Block – Screwed into the battery board, holds the ESM32-CAM motherboard in place.
Note: Recommend ABS or PETG for 3D Printing due to outdoor use.
