HELLO, CURIOUS HUMAN.
Hi, I’m Dheeraj.
I make ideas work.
Here to know me? Got something you want me to build? An old friend unlocking memories? Or are you offering a treat?
Yesss… you found the right Dheeraj. 😂
I turn “wait, can we actually make that?” into circuits, code, robots and connected systems.
SMALL-TOWN ROOTS✳BIG “WHAT IF?” ENERGY✳HANDS-ON, ALWAYS✳STILL FIGURING COOL THINGS OUT
ABOUT ME / A WORK IN PROGRESS
Curiosity is
my default setting.
ElectronicsEmbedded systemsRoboticsIoT
My story started in a small town in North India—with radios, motors, library books and the pages of Electronics For You, Vigyan Pragati and Avishkaar.
That habit of asking how things work grew into thousands of circuits, real-world systems, a company, and a lot of shared learning.

01 / WHAT’S IN THE TOOLBOX?
What I bring
to the workbench.
I enjoy the spaces where physics, electronics, code and mechanisms meet. No skill percentages. Just the things I work with.
Radio & communication
Receivers, antennas, RF experiments, Morse, wireless control, signal exploration and communication systems.
Robotics & fabrication
Motors, actuators, CNC experiments, mechanical integration, lathe work, casting, forging and milling.
Software & computing
C/C++, assembly, Linux, networking, hardware diagnostics, web development, billing and inventory software.
Signals & applied research
EEG and BCI experiments, physics and mathematics, AI/ML project guidance, PLC/SCADA training and FPGA study.
Connected environments
IoT devices, home automation, energy monitoring, water management, hydroponics and system integration.
02 / THINGS I ACTUALLY BUILT
Selected builds.
Real-world thinking.
From experiments on the bench to systems in real buildings. Pick a rabbit hole. Open a field note.
8 field notes
Installed system
Room-addressable, full-duplex PA system
Hundreds of rooms. One connected voice.
A communication system installed across a large building with hundreds of rooms. Room addressing and two-way communication brought electronics and system integration together.
Okay, let’s get nerdy +
Addressing → Communication → Room endpoints
The work combined room-level addressing, full-duplex communication and integration across the building. It reflects my interest in taking an electronic design beyond the workbench into a complete system.
Experimental prototype
EEG & brain–computer interface
When a signal becomes an interface.
I explored EEG signals and developed experimental software for cursor movement and word selection through a brain–computer interface.
Okay, let’s get nerdy +
EEG signals → Processing → Interface action
This was experimental work in biomedical signals and human–computer interaction. Signal acquisition, interpretation and software feedback were the core learning areas; it is not presented as a medical device.
System development
Hospital energy management
Give energy a little more intelligence.
Energy management work in a hospital, alongside connected metering and room-proximity-based control projects.
Okay, let’s get nerdy +
Sensing → Control logic → Monitoring
My work connects physical sensing, embedded control and monitoring. These projects bring together device-level electronics and the wider needs of a building.
Control systems
Hydroponics & indoor plantation
Plants, pumps. A feedback loop.
Control systems for indoor growing, connecting environmental sensing with the operation of a growing setup.
Okay, let’s get nerdy +
Sensors → Controller → Growing equipment
Hydroponics and indoor plantation projects combine sensor integration, embedded decisions and physical equipment. Soil-testing equipment is another part of my agriculture-related work.
Product & system work
Attendance & underground tracking
Knowing who—or what—is where.
Manufactured RFID attendance systems, worked on face-recognition attendance, and developed an underground mining tracking system.
Okay, let’s get nerdy +
Identification → Processing → Records
These are separate projects united by identification and tracking. RFID hardware, face-recognition software and underground tracking each required their own integration approach.
Bench experiment
Wireless power-transfer experiment
Power. Without the wire.
I built a system that transferred power over a distance of up to 10 feet.
Okay, let’s get nerdy +
Transmitter → Wireless coupling → Receiver
A hands-on exploration of wireless energy transfer. The distance describes my experiment; delivered power, efficiency and test conditions are not documented here.
Devices & prototypes
Home automation & useful gadgets
Everyday problems deserve good circuits.
Sensor-based water management, security systems, Wi-Fi/RF/IR switches, a connected geyser, automatic desert cooler and versatile timers.
Okay, let’s get nerdy +
Input → Embedded logic → Output
Work included remote control, sensors and timing logic, including astronomical timers. These builds put electronics to work on practical household tasks.
Experimental builds
Robotics, mechanisms & CNC experiments
Old drive. New purpose.
Robot prototypes, stepper-driven mechanisms, CNC drilling experiments and automatic antenna positioning using repurposed parts.
Okay, let’s get nerdy +
Code → Motor control → Motion
Mechanical fabrication and electronics meet here: salvaged motors and sliders, custom hardware and microcontroller control. I learned through building, testing and improving the mechanisms.
Diagrams are conceptual sketches. Illustrated portraits are creative scenes, not project photographs.
03 / THE CURIOSITY TRAIL
No straight line.
Just a lot of “what if?”
A journey told in chapters, not dates. These interests overlap—and many are still very much alive.
Curiosity switched on
Magnets, motors & a little magic
Homemade electromagnets, a brushed DC motor, an electric bell, mechanical drum sequencers and decorative lighting. I explored emergency lights, DC-to-AC conversion, a working gramophone model, tape recording, telescopes and microscopes.
Chasing invisible signals
The air was never empty.
SW, MW, LW and FM receivers, transmitters, antennas, Morse experiments and listening to amateur radio. Remote-controlled cars, early flying prototypes, small petrol engines and radio astronomy experiments turned invisible phenomena into something I could investigate.
Inside the machine
Opening things was the tutorial.
Computer hardware, printers, hard drives, memory and power supplies became a practical classroom. GW-BASIC and COBOL led to C/C++, assembly, low-level software and boot-level exploration. I also wrote small games and explored disk diagnostics.
Making useful things
From spare parts to side quests.
Computer repair, billing and inventory software, hardware and networking teaching, and running two affordable cyber cafés. Repurposed printer, floppy and optical-drive mechanisms became CNC drilling and antenna-positioning experiments. A battery-powered bicycle joined the list.
Code meets the real world
Now the ideas could move.
Atmel and PIC microcontrollers, robot prototypes, Linux and multi-system networking. I explored lathe work, forging, casting and milling, then combined fabrication, circuits and code in practical devices. EEG and brain–computer interface experiments opened another rabbit hole.
From bench to buildings
Small circuits. Bigger responsibilities.
RFID attendance, connected geysers, hydroponics control, soil testing equipment, hospital energy management, underground tracking and a room-addressable PA system spanning hundreds of rooms. I founded Ekworth Tech Pvt. Ltd. to build professionally.
Passing the spark on
Knowledge gets better when shared.
Thousands of student-project consultations across embedded systems, IoT, robotics, AI and ML. Dozens of workshops, STEM kits, physics teaching and hackathon mentoring—including teams that won first place. I keep learning through PLC/SCADA, FPGA and new experiments.
04 / PASS THE SPARK ON
“Ohhh, now
I get it.”
Still one of my favourite things to hear.
I’ve consulted on thousands of engineering student projects, delivered dozens of practical workshops and developed STEM kits that help ideas become tangible.
My teaching spans physics, computer hardware, networking, embedded systems and robotics. I’ve also mentored hackathon teams, including first-place winners.
