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:

All information provided in this post is for educational perposes only. I do not support nor encourage this monkey business. If you choose to make this device; you, and only you will be responsible for the consequences. Happy building!

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 »

Really damn bored…and too lazy to write anything, just look:

I had an old Genious G Shot D211 lying arround, and it was pretty much useless because of many small reasons, which Im too lazy to state.

After reading a lot of tutorials on making IR cameras, I thought ill do one myself. Making one is not exactly ‘making’ it, rather modifying or hacking an existing camera. It can be done to any model, but remember every model has a different type of IR filter in it. Some can be removed easily, some have to be broken like mine. Some are transparent paint like a nailpolish or a solid glass with IR on one side and UV on the other, like mine.

Some usefull links have been provided at your disposal to check other mods/hacks etc.

If I get a good response, ill be uploading more pictures for you to check out.

This picture was taken outside with no filter at all. That means UV, IR and Visible spectrum, all get into the camera. This kinda makes the picture look weird. So remember if you have removed your IR filter permamanently then you’re probabily stuck with an IR camera. ONLY

The picture with a fully exposed piece of negetive. This blocks Visible light. There is not much of UV that a cmos camera can detect (more on this later). So, its just IR with whites meaning IR, blacks meaning no-IR.

Lifestyle Next_

Comfort is our primary need. We have strived for ages to make our lives comfortable. From fire which keeps us warm and have great food, to shelter and work to keep us busy.

The new times are making us more comfortable and ‘content’ but with a price. Couch potato is a familiar term and we all know it affect us with increasing ease of technology. I am really afraid to predict the future where we have personal robots, automated homes and human-machine interface. Maybe we will just lie down and live our lives (If it’s ok to call it a “life”). Visit office from home; get food by robots, open windows/doors with the mind, brush teeth, automated flirting algorithms, and more scary automated ’stuff’! Anyway, let’s be optimistic.
