Introduction

In this tutorial I will just introduce the PC Parallel Port and how to identify its address for use in home electronic projects. Mind you the whole process and learning takes time but is fairly easy too! Remember, if you are interested then keep learning and trying new things. Fill me in if you have any questions or suggestions.

The Parallel Port is the most commonly used port for interfacing usual devices like printers and scanners. It’s found commonly on the back of your PC as a D-Type 25 Pin female connector. But did you know it can even be used to make home made projects?

DETAILS:

Pooja Audio-Video To RF
Video C.D. Converter
Model V-CD 250
Made in India (Exclusively Local)

I bought this about 5 years ago in India, took me a while to find this awesome (at that time) device. Used it to connect my Playstation 2 to an old Sony TV which just had a single RF input port.

This Audio-Video to RF converter did exactly what it says. You connect your composite vid to the black connecter and one audio (no sterio) to the red and the RF output to your TV. Set at appropriate channel and fine tune with the pots at the back. Thats it.

This is the first post for my dear twit. Whats in all those awesome (or boring) electronic equipments/devices etc. I started this because of two things.

1. Inspired by Take-it-Apart.

2. Got bored back home in KSA and opened up a lot of stuff. Had to do sometihng, so documented the whole (time wasting) activity.

3. I could salvage a lot of useful electronique parts even out of old obsolete devices.

So have fun and wait for more upcoming twits

Note to enthusiastx: If anyone has time please have a look at the IC list given with each device and send in/comment how they work so others can have a good idea how the thing works.

We, and I mean all of us existing (with no intention of generalizing), have a tendency to ‘Label’; a genetic habit of trying to place something somewhere within a ‘group’. Why do we do this? As I said it’s genetic.

Not surprisingly, we have a tendency to label even the un-label-able and sometimes label the lables themself (damn those homophobes). Now I could go on about labeling the anti-labelers (antiracist? what about pro-anti-racists?)

J. J. Leonard and Hugh Durrant-Whyte, in the last decade, briefly described the general problem of mobile robot navigation by three questions: “Where am I?,” “Where am I going?,” and “How should I get there?.”

I was shocked to realize that these 3 basic questions which we, ofcourse take for granted(!) are actually immensely complex implementations in robotic systems.

What I found interesting is that to date there is no truly elegant solution even for the “Where am I?” part! A collection many partial solutions can roughly be categorized into two groups: relative and absolute position measurements. Because of the lack of a single, generally good method, developers of automated guided vehicles (AGVs), unmanned flying vehicles (UAV’s) and mobile robots usually combine two or more methods, one from each category. These two super-groups can be further divided into sub-groups as shows below.

Today’s Selection

Excellent video lectures on Op-Amps and circuits from MIT. Click here to visit the whole page or watch each video.

These are 50 minute videos (rm) are with full explanation. A good watch!

I never thought I will write a general entry to my blog. But non-technical can be as interesting as technical (N3RD alert_).

So anyway. College is fine, except a few glitches with my right hip. Because of which I get a little cranky and irritated.

Still in the making: Tilt sensor. FM bug.

www.crazyengeers.com recently interviewed Jessica Arnold (Microsoft® Outlook® Product Manager) (All because of our amazing admin Biggie_K!)

We are planning to interview a few professors of MIT too, in some time though. Since forming informative Q’s is not reallyyy easy. Moreover, they dont have much time. Last time they had Dan Kuykendal (Director Of Engineering, NTObjectives Inc., USA) – the man behind Mighty Seek Podcast, podPress, project - phpGroupWare, rpmBuilder, Qmail & podcastAlley!

Keep watching for more interviews. (/N3RD Alert_)

In short: “Listen in to the telephone conversation on your radio!”

But before that here is a disclaimer:

Lets move on.

I had taken my old Landmine Landline (wired) phone and thought of making it a cool spy device. You know like in the Bond movies, only difference being this one is a little bigger. Click on a image to enlarge it.

I dont have to explain this one. Read more »
