  • 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

  • TSAL_KE1_Green

    TSAL_KE1_Green

    Designing a Tractive System Active light(TSAL) circuit for an Electric Vehicle which does the following operations 1. The TSAL itself must have a red light, flashing continuously with a frequency between 2 Hz and 5 Hz and a duty cycle of 50%, active if and only if the LVS is active and the voltage across DC-link capacitors exceeds half the nominal TS voltage 2. The TSAL itself must have a green light, continuously on, active if and only if the LVS is active and ALL of the following conditions are true: ● All AIRs are opened. ● The pre-charge relay is opened. ● The voltage at the vehicle side of the AIRs inside the TSAC does not exceed 60 VDC or 50 VAC RMS. This schematic will include only the Green Light logic. We have to take proper care of High voltage and Low voltage isolation in this schematic because it will have to be implemented on the PCB as well.

    New Part Template pfZM

    A simple voltage divider to showcase how to make parts. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.
