Headphone Amplifier Using IRF510 MOSFET/12AU7 Tube

The project is known as NP-100v12 which refers to a simple headphone amplifier built around the 12AU7 vacuum tube.

Swarm Robot Project with Open Source Design

The project aims to produce open source swarm robots that are fully autonomous with programmable and natural emergent behavior in a 20x28x15mm size only.

FM Receiver with a Single Transistor

This project contains a very unique one transistor FM receiver  accompanied by homemade air-core coils and a homemade fixed capacitor.

Micro-Step Driver for Bipolar Step Motor

The device is designed to use parallel ports in order to connect a bipolar step motor to a personal computer.

Building the Simplest TV Transmitter

The project aims to create the simplest TV transmitter from the simples FM transmitter project by just changing the input from the audio to the video and checking the TV signal.

Punch Accelerator Used for Measuring Punch Intensity

The project shows the power of a punch by displaying the hit expressed in numbers as the project uses an Arduino and an accelerometer.
