Toy grenade for airsoft, that produces sound via controlled pyrotechnic ignition. Designed, programmed, tested and manufactured a user-ready product from scratch. Adapted to user feedback to improve the product Developed a reliable ignition system. Designed a convenient user interface - display, switch, buttons. Used ESP32 / ESP8266 to allow sensors integration and WiFi connectivity. Designed a high-impact structural enclosure to withstand mechanical stress from explosion and throwing. CAD optimized for sound strenght and safety.
Designed and built a custom drone using basic components - ESP32, ESC, gyro- and accelerometer Stabilization with PID controll BLDC motors driving Remote control using WiFi over UDP Modeled and 3D printed frame Power management from 3S Li-ion batteries
Attachment for airsoft guns, that counts BBs coming through, measures their speed and lights them with UV. Used IR LED and photodiodes to create highly sensitive high-speed proximity sensor Amplified and filtered the signal. Detect the signal using ESP32 Power up high-consuming UV LEDs. Reduce power consumption by 90% Show data on an LCD Designed custom PCB for large-scale production
Use variable-inductance coil to detect metals in proximity The device can detect a coin in up to 50 cm Combine 2 similiar-frequency collpits oscillators to make a beat. Beat signal frequency is much easier to measure. Filter and amplify the signal Process the signal using ESP32 and connect a buzzer.
An interactive web application that visualizes how a multi-layer neural network learns to recognize handwritten digit patterns. Users can create 5×5 binary patterns, run predictions, view the network architecture and weights in real time, and train the model by providing the expected result. The project also includes pattern storage and network weight management, making it a practical demonstration of neural network learning and classification.
