Using a PIC18 MCU a IR motion detector circuit that is currently configured for security purposes was built. The code and I/O devices can be changed for other functions such as triggering an automatic door with a servo or many other functions that require a motion sensor to be used. The circuit is built on […]

Stealth FM Pirate TX/RX
This project consisted of building two separate devices to receive and transmit a signal over the FM spectrum of 88 to 108 MHz. Originally the idea was to make a discrete pirate radio station that can be easily transported inside a pocket. When the transmitter is turned on, any radio in its transmission radius can […]
Diffie-Hellman Key Exchange
The Diffie-Hellman key exchange algorithm is the backbone in the majority of the internet sites and apps that we use. It is a fairly simple algorithm, yet it’s simplicity and ease of use (most of us don’t even realize it is being used) is what makes our communications secure. The Diffie-Hellman key exchange allows two […]

Decoding Airband Signals with MATLAB
The goal of this project is to analyzed an RF data file (.dat) that included airband AM signals captured around Palo Alto Airport ATIS, using an RTL-SDR tunner centered at 135.5 MHz. Through the use of Matlab and provided functions the 10 second data file was analyzed with a spectrogram function that allowed to visualize […]
