Escomma - A circuit simulator using linear and non-linear equation solvers. It converts the spice netlist into a sparse matrix and uses LU decomposition and Newton-Raphson to solve the node voltages.There are plans to add interfaces to octave to enhance modeling. Extending the math library to include finite element method for magnetics analysis is also planned. It is written in C and released under GPL. [more]
[ 06-27-2009 ] I created a haskell version of some section of my very old project called escomma. It can be downloaded from my contrib section. link
Mazda B2200 - This is my old pick up. When I have time I do some simple maintenance and modification. I ask my brothers help when things gets beyond my level of skills. [more]

Madcat F - series
This sketch was derived from the game Mechwarrior.
I no longer play the game ever since I switch to using Linux, This
is how I remembered my favorite mech.

The Grim Reaper. I was trying to depict a very scary bringer of death
here. I am not very good with this so I just pick what I can.

snake and skull - This was suppose to be a logo for my old web page.
It started to look boring after a few days so decided not to use it.
The snake is smiling and the skull looks more chimpanzee than human.

[ 03-07-2009 ] Seeing that haskell code looks
a lot like equations and plan9 plot makes an easy way to create graphs.
I thought it would be easy to create a simple smith chart program.

[ 09-17-2008 ] I created a skin for my palm T|X. It is just a flat version the dimitry's cobalt theme that came with skinui. It is accessible through this link
[ 01-10-2008 ] Moving some of my major projects to plan9. Some of them can be found in the contrib section of the Plan9 website.
[ 11-19-2006 ] My network has been restored. I was able to fix thinktank's monitor, it was a leaky flyback capacitor and the High tension wire was causing a discharge. New capacitor and electrical got it back up again.
The network is up, however the hardware is aging. 9 months not much update. Check out new pictures of my pickup.
[ 02-02-2006 ] I was able to restore Thinktank but the monitor is in bad shape. I hope I can save enough money by next month \ to Buy a new monitor.
[ 11-11-2005 ] I am still alive at least I think so. A bunch gremlins thought my website sucks and decided to get even and I decided to revert back to the old archives. My main server Thinktank went down a few months ago :P, My theory is it got hit by a static charge from the lightning storm during that period because the TV card was left connected to the arial. Well it wont boot anymore and I am trying to set it back up again. I am currently using my aging laptop Arachnid as a Linux workstation which connects to my plan 9 cpu server Anubis. Anubis is a bit old also and the disks are starting to give up. A very depressing story. The good news is I still have most of my files backedup and shouldt be much of a problem restoring them. My work on circuit simulation still continues but compiling it is starting to get real slow without Thinktank.
[ 01-08-2005 ] I went to China and was unable to make any updates on my projects. Anyway I decided to try crux linux distro. It is designed to be very small allows you to make it bigger in any direction you want. I really like crux and I think I will be using it for a long time. Maybe one of these days I will write a review about all the distros I have used. I used a few including a couple of bsd's well don't hold your breath I am very lazy :)
[ 12-04-2004 ] I am still doing some update on escomma. I was hoping to upload it last weekend, But discovered a bug in the resistor matrix loader, which took me the whole weekend to fix. I also found a whole bunch of links about circuit simulation and power electronics, I will probably put it up on my escomma project page.
[ 11-02-2004 ] I finally had time to do some editing on this page. Most of the links doesn't work yet and typo are still being checked. I also found some time to continue coding escomma and I think I can upload a new release in the next few weeks. maybe....
Escomma is something I cooked up several months ago. Its a circuit simulator which I started writing in order to further my understanding of numerical analysis. It is not as professional like ngspice or gnucap and those are the ones I use to verify escomma's results. It is released under the GPL license. I have a lot planed feature which may or may not happen. Coding was stopped because I had to concentrate on work a couple of months ago, But now I started to get into the whole thing again.
