Happy New Year – 2011

Though slightly belated, I would like to wish Happy New Year to my readers, I’m still alive btw, altough swamped with work, battling anxiety, more on that later.

Sporadic update….

Hey there guys, I know I havent been writing much. I’ve even missed the August month completely!, the thing is, I currently working on a project which demands most of my creative time, and by the time I’ve some free time to spare, I’ve already gone tired.

But rest assured, I’ll begin to make time again as I’ve already on the final phase of the research project. Be sure to remind me every now and then to write stuff around here!

DIY Cooling my DSL-2640T ADSL Broadband wifi Router

This is the continuity of my previous posts My Modem Gone Up in Smoke! and Inside My Linux DLink G-604T Broadband Modem/Router. Seems my local vendor finally replaced my faulty G-640T after eight month use with a new broadband wifi/router with same capabilities albeit different model (G-2640T). The new model is smaller, has shorter antenna and generate more heat than its predecessor.

I hate going back and forth from computer shop and my house to claim warranty, I prefer to have a fully working hardware that I can truly rely on. Thus acting on advice from my blog readers (especially Azmeen and Kucau I decided to improve the air ventilation for my broadband modem.

Because I dont have an air conditioner, I have to improvise in order to keep my modem cool and ventilated, I removed the outer casings of the modem and attached an ordinary 12volt casing fan on top of it with a strong glue. I powered the fan with a general purpose low voltage AC/DC adaptor (‘walkman’ adaptor) to make sure the modem stays cool during operation.

The Result
Without fan, the modem capacitors heat up so fast (approx 30 minutes) that it could burn up my fingers. The attached casing fan dissipate heat quickly resulting the modem circuits felt as cold as water.

Here’s a photo of my modification

FFMpeg based FLV to 3gp batch converter scripts

A friend from #fakap asks me to create a dead simple FLV to 3gp batch converter for him to port youtube clips to mobile phone.

As a result I complied, and created flvto3gp bash script for the job.

Usage
Using it is simple, just run this script inside a directory full of FLV (or any video files supported by ffmpeg) and execute it using this command :

sh flvto3gp.sh *

The script will convert all video files to 3gp file format one by one. The script requires
ffmpeg in order to run.

Ubuntu users might have to refer to this post before using this utility : Enable mp3 and amr support in ffmpeg ( Ubuntu )
