Portable Headphone Amplifier Known as CMoy

The CMoy portable headphone amplifier was designed for testing purposes while using a single OPA134 op-amp in a non-inverting configuration.

Universal Frequency Counter

The project is based on Lattice ispLSI2032 PLD and AT90S8515 microcontroller to create a universal frequency counter that has the ability to communicate with PC via serial port.

Oscilloscope Display from Nokia 3310 LCD

The project illustrates the interfacing of Nokia 3310 LCD to create a simple scope that would display low frequency sine wave.

dsPIC Test Board for DSP

The objective of the project is to create a DSP based on dsPIC microcontroller since they have built-in DSP engine that allows fast multiply and divide operations with arrays.

Temperature Meter Powered by COM Port

The project aims to create a simple four channel temperature meter that can be connected directly to the COM port of the computer without the additional power supply.

Connecting a Solar Panel to Arduino

The project was designed for the possibility of connecting a solar panel with an Arduino board where the information is read in Max/MSP.
