Working on augmented reality wearable solutions. Full scale system design using SOM's (system on modules) and compute module's. Writing custom drivers for Linux. Designing PCB's(flex and rigid). Circuits debugging and testing components interaction.

Worked on DIY projects involving microcontrollers, sensors/actuators and other hardware peripherals. I document the functional part of the project by explaining the overall idea, use cases, circuit design, peripherals interconnections and code. My projects are then published on Engineers Garage. One of the website under WTWH media LLC management. Few Projects Analyzing STM32 low power states Webserver using STM32 and Broadcom DEV-board OLED power savings analysis with arduino Simulink GUI peripheral's control with arduino inputs Nextion HMI display programming and peripherals controlling Power monitoring using non-invasive current sensor Raspberrypi and camera encoding decoding qr camera

I was running a website for almost 6 years on which I uploaded DIY projects related to microcontrollers( Stm32, Microchip, Arduino, 8051, ESP8266 ) circuit design etc. Website was acquired by WTWH Media, LLC back in 2019 and my 200+ projects are part of a bigger network. I am proud of it. Some of my Projects ✓ Calculator made with Arduino, Pic16f877and 89c51 microcontroller. ✓GCM (Google Cloud Messaging) product delivery system. ✓Serial Communication using Pic16f877, Arduino and 89c51 Microcontroller. ✓PWM (Pulse Width Modulation) generation and speed control of dc motor cars using 89c51, Stm32 and Pic16f877 Microcontroller ✓Digital Clock with Arduino, Pic and 89c51 Microcontroller. ✓GSM (Sim900d) interfacing with Arduino. ✓Clock and Calendar with Arduino. ✓Pickit2 designed by me (Programmer for Programming Pic Microcontrollers) Some end products USB HID Stick using Atmega32u4 microcontroller and Nordic Nrf51822 BLE 4.0 Module. Stick is used as remote keyboard. Connects to Android mobile on Bluetooth and whatever is typed on mobile is similarly typed on the Laptop. Circuit, PCB designed by me and PCBA in quantity from China. Custom designed board for process control (16 Input/output) using pic16f877A microcontroller. Like mini PLC. Project includes components selection, circuit building, PCB designing (Tracing, Etching, Drilling and Milling, Soldering). A simple demo industrial Process is presented and controlled by me. Project includes conveyor system control and product manufacturing. PLC is programmed using standard Ladder language Smart Irrigation System Probe measures the moisture level in soil and temperature. Circuit and PCB designed by me and printed from china. Composed of SMD components. Car Automation automatically switches the head lights of Car ON-OFF depending on the visibility. Monitors the battery of the car and engine temperature. Powered through car battery. Displays everything on a 16x2 character lcd.
