LaserProjector V2 is a battery-powered, ESP32-based laser XY scanner using stepper motors to deflect the beam. It has auto-homing functionality, and can be controlled wirelessly.

LedBox V2 / V2.1 is a multifunctional ESP32 based, WLED compatible controller for 3/4-wire, 5-12V addressable LED strips, including digital microphone, side button and IR receiver.

reTerminalEM is an expansion module template for reTerminal's unique high-speed interface (PCIe X2, USB 2.0, POE, 2x I2C, 2x SPI, UART, and 11 GPIOs).

Grow light with websocket interface, manual control, and 24-hour scheduler, based on ESP8266 controlled 4-channel relay.

TriangleLight is a battery powered RGB mood lamp supporting multiple operating modes such as manual, automatic, bluetooth remote, and music control.

All presented styles are focused on connection between technology and fashion. They were created under BrainCircuit team for AWOW 2017 contest.

This rechargeable and battery-operated device is capable of reading and writing UID of HF RFID (13.56MHz) cards/tags, effectively capable of cloning.

Stepper motor driven laser projector capable of two dimensional scanning, blanking, automatic laser homing, and wireless bluetooth control.

A small robotic arm with 4 degrees of freedom and a gripper, made out of aluminium brackets and SG90 servo motors. The control unit consists of Arduino Nano and 5 potentiometers, used to control the movement of every joint.

A client-server home automation application using Java Remote Method Invocation (RMI), capable of user authentication and remote control of dual relay module based on privileges.

Velocity sensitive drums using the signal from piezoelectric transducers sampled by Arduino's ADC, and generating corresponding MIDI messages.

A laser engraver from old floppy drives driven by Arduino Nano flashed with GRBL firmware. The first prototype used A3967 EasyDriver stepper drivers, but was then replaced with Arduino CNC Shield.

By adding capacitors in series with the MOT output, the system can be brought to resonance and the arc length is visibly increased.

Plasma speaker - MOSFET switched flyback transformer driven by frequency modulated NE555 astable oscillator, producing audible artefacts.

Do you have an old microwave oven laying around? This project describes a spot welder made out of two Microwave Oven Transformers (MOTs).

Only one transistor and two resistors are needed to make this well-known self-oscilating flyback driver, whcih makes it a simple starting project for beginners.

A simple, yet interesting way of magnifying floating objects in liquid using just a syringe and a laser pointer.

This is my high-school student project from 2012, devoted to effect of electromagnetism and practical construction of optical-gate based electromagnetic levitator.
