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.

Design a circuit that detects the presence of the infrared signal. The circuit should light a red LED when infrared signal is detected otherwise it should light a green LED. You may use NPN transistors, IR LED, Photodiode, Red LED, Green LED and a rectifier diode.

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
