  • Lethal Company Pro Flashlight Power Board V1

    Lethal Company Pro Flashlight Power Board V1

    Lethal Company Pro Flashlight Broken Features: - U2M cannot be line powered from this circuit so the LED driver does not regulate. [Find the acompanying button board here](https://www.flux.ai/markwuflux/lethal-company-pro-flashlight-button-board) -Ultra bright -Makes click noise from speaker -Wirelessly transmits battery life (maybe use Ubo to receive this) -Drive a SST-40 Chinese LED I want this thing to be super bright! The brighter the better, but keep it simple. These LEDs will draw a lot of power, so we need some sort of CC source. It doesn't have to have high bandwidth. I am thinking about a DIY microcontroller buck converter with PID duty cycle control. Mistakes in this V1 design: - No pullup resistor on PG of Module1

  • WiFi Door and Window Sensor

    WiFi Door and Window Sensor

    A compact battery-powered door/window sensor built around the ESP32-C3-MINI-1-N4 module. The design uses a single non-rechargeable AA cell with a TPS613221A 3.3 V boost regulator, reed switch magnetic contact sensing, low-power wake/report/sleep firmware strategy, RGB status LED for setup feedback, BOOT/EN controls, programming header, and input polarity protection. It is intended for smart-home security and automation applications, supporting WiFi or Bluetooth LE hub reporting with emphasis on low idle current, reliable RF burst power delivery, and field-replaceable battery operation. #ESP32-C3 #BLE #WiFi #DoorSensor #WindowSensor #ReedSwitch #LowPower #BatteryPowered #SmartHome #IoT

  • Webcam & TouchKey Laptop PCB

    Webcam & TouchKey Laptop PCB

    This project involves designing a PCB for the lid assembly of an open-source laptop. The design integrates various sensors, including a microphone, camera, and ambient light sensor, ensuring precise alignment with the display glass. It features touch sensors to control LED lighting, spring-loaded contacts for touch-key interaction, and 3D-printed light diffusers for efficient lighting. Additionally, the PCB includes a power management system with status LEDs and a PFC for connecting to the external laptop PCB. The goal is to create a versatile, upgradeable, and user-friendly component for the laptop's lid. Specific parts of the project include 1. Microphone - Audio input capture 2. Ambient Light Sensor Module - Light intensity measurement 3. Camera - Video capture 4. LDO Regulators (3 TLV74 Series) - Voltage regulation for different components 5. Crystal - Clock generation 6. Touch Sensor Controller - Touch-key interaction 7. Flip-Flop - State keeping in logic circuits 8. LEDs (LTRBR37G Series) - Lighting indication 9. FPC Connector - Interface with main laptop PCB
