Holden's website

About this site

This is my personal website where I host several projects I work on in my free time. They are mainly about C programming, Webcams, Linux, Electronic Circuits, PIC microcontrollers, Raspberry Pi etc.

Linux / Programming

hwebcam v4l2 webcam capture/streaming program in Ogg/Theora/Vorbis format
Seren VoIP conference program with ncurses interface based on the Opus codec
parole A simple cli VoIP program based on the Opus codec
pf-upnp Cli program to list/query/add/remove port forwarding entries using UPnP

PIC Microcontrollers

rpp Raspberry Pi PIC Programmer using GPIO
synthesizer.c A simple music synthesizer. I wrote this program because I wanted to put a tune inside a microcontroller, but I wanted to check first if all the notes were correct. This is the kind of output it can produce: happybirthday.ogg, odetojoy.ogg, and overtherainbow.ogg

Random Numbers

chua Random Sequence Generator based on Chua Circuit
avalanche Random Sequence Generator based on Avalanche Noise

C Language / Old stuff

fdm An electromagnetic field simulator I implemented a while back. It uses the finite difference method in order to solve simple problems such as finding the electric potential in the region between two perfect conductors. These are some of the images of the simulations (click on the image to enlarge):

More images here, here and here
hftp A simple ftp client
balls.c This one generates a sequence of images of moving balls that you can join together into a movie, like this one
