They need a little bit of your time…

Sometimes all they need is a split of a second. A wink of an eye, a minute of yours, a flick of the hand.

Well, a boring Saturday yet again being summer and no travel plans. Summer is a bad time in Karnataka to travel.

This post was actually inspired by the book ‘Blink’ by Malcolm Gladwell. I bought this book on the roadside pirated book stall who manages to give you the one at 1/5th the market price. Recession times leads to low cost solutions :-)

The author describes the main subject of his book as "thin-slicing": our ability to gauge what is really important from a very narrow period of experience. Here are links for a bit more description of the book from Wikipedia.

The book put me thinking on slightly different lines.. About people just like about ‘blink’ instances.

I’ve had a few experiences personally and have seen quite a few, when someone can do wonders with a flick. All people need is a spark, an ignition or a word of comfort sometimes. The first instance I can recall was a couple of years back when I was diagnosed with malaria and lay on the bed entangled in the drip pipes for 3 days. Every day the doc used to attend me twice. It was nothing that he did, but just speak a few words and check the temp scale. But those two visits game me real inspiration that I was doing well. The body used to cool own, eyes used to lighten up, some energy used to encompass for about an hour. It is no surprise, as each of us would have felt in a similar way. I could narrate a few more of similar or better ones but a little bit enthusiastic to get into the crux of the matter.


Sometimes it so happens for people that they get into situations or problems or happy things that they need to share. It happens so, that they want a pair of ears to listen and a pair of eyes to look at for expressing themselves. Very much like machines, which when oiled and greased at the right time works fine for years else it breaks down . The ability to thin slice such situations will remarkably make a difference for those who need it.

Btw, here is another incident which happened in college, when a friend of mine was totally depressed for a personal reason, which I ended up discovering was a breakup. He was totally down for a week, and incidentally we had invited him for a trip the nearest weekend. Our intention of invite was out of the blue as another guy who had to join us backed out, and college experiences say that trips are more financially viable if there are more people. Now, we spoke about everything like breakups, college rumours, how-i-will-be-a-few-years-later and many more things during the trip. It was an enjoyable trip as always, and a couple of days later this guy invites us all for a treat in an expensive restaurant and explains us the whole story about his breakup, what we spoke fitted into his life and how he understood a lot of things from the conversation. He was a happy man that day! So were we, with sumptuous food for free :-P. Incidentally we never knew that we were with him at the right time when he needed it. It just happened, unknowingly and that made a big difference to him. He is a successful guy and doing his PHd in the US now.

There are some people who might come and ask directly and some maybe pale white shy and express their concern in indirect ways. Parsing such situations to understand what they want is completely onto our abilities and thinking processes and is a challenge. The paradigm shift is what some people do to determine their situations and reasons, in short, reading between lines. There are some of us who believe that “If you have a problem, tell me I’ll solve it”. For some it does not work that way. People might always not need a solution for a problem. The problem, a lot of times is a solution in itself. If everyone were straightforward… psychiatrists, counselors, negotiators would be jobless. I’ve read that such people are highly paid by governments to determine the behavior and character of captured fugitives or their own soldiers, to read between lines and to predict the behavior or counsel them. That’s not much in the purview of this topic.

Sometimes it happens that because of our visual shadowing of people’s personality model, the cognitive abilities get masked.
But the fact, that the difference the time slice can make is immeasurable. There have been instances where kids took extreme measures as their parents were busy and did not spend ‘quality’ time with them or mafia gang leaders quitting and leading a normal life just because they could speak with someone and ended up finding out what he had done so far was wrong.

We all are wired differently, so it’s extremely tough to predict behaviors. But it is proved fact that there are definitive patterns that can determine what a person has got to say. .....For the time spent well at the right time can be more rewarding for either sides than we could all imagine.

I would be glad to know what you all feel or think about this ‘perception’ of giving your time..

A Do-It-Yourself Solar Powered Laptop Cooler

May 1st week and Bangalore was hot. More so with we being used to AC's all day in office, it was pretty perspiring to sit at home. On the weekend, with so much of temperature, it was not a good idea for me to go out driving in the burning sun I thought, and took towards a favorite pastime.
Yeah, scrapping and facebooking and Gtalking. Its been hours since I began and still had my laptop with me all heated up. It wasn't a good idea to use a laptop as a laptop but rather found out that the name 'notebook' suits more. Probably someone who was intelligent enough that laptops cant be used for long on laps renamed it as 'notebook'
I thought I'l go buy a laptop cooler, and checked the price online. It was a cool 1700/- a one from Belkin with a 9v power adapter.

Being a boring friday noon, (1st may and a long weekend) I happened to spot the Solar Panel that was gifted by my company NSN as an annual gift as a part of the Go-Green initiative. Unfortunately the lamp ceased to work, thanks to the not-so-good battery provided inside.
So here I was with a project to build a Solar powered Laptop cooler.

All you need is some raw materials and some time :-)
The nearby computershop guy was happy to provide me a 12v 100mA CPU casing fan for a cool 70/- and I bought this writing pad made from cardboard that we used in school for 20/- at a nearby stationery shop. The project was to cut a hole in the pad, and fix the fan onto it and connect the DC fan to the solar panel.

How to:
  • Cut through the pad with a hacksaw with the fan sweep as the diameter. Selecting a slightly offset point on the cardboard would help, as the laptop heating points are not at the middle but somwhere between the middle and the topleft corner. It would help if the area you cut is made slightly wet as cardboard gives way easily at those areas. Now drill 2 holes into the pad and affix the fan with a pair of screw and nut provided alongwith the fan.
  • Now connect the panel power cable (its assumed to have pretty long about 10-15m) to the fan. Check the direction of the airflow before drilling or fixing the fan as the fan does not reverse direction if you connect it the other way round thanks to the internal circuitboard within the fan coil

The panel I used gave me an open circuit voltage of 10.09V 500mA. perfect for the fan of 12V to make it run at 80% of the speed. The fan running at full speed will not give as much airflow as 80% of the speed.

The device is working great for me. I first place it on my lap with the air exit towards my face, and place my laptop on top. The temp under the laptop has reduced by 8-10 degrees which is about 30% improvement. All at a cost of 100/-
In case you dont have a solar panel, you could use an old power adapter of 12v ~350mA for instance like the one I am using is from an old cordless phone. Buying one will cost 150/-
You can also use the power from USB of your laptop. In that case you need to buy a USB port male pin and a 5V fan instead of 12V. You can get the USB configuration here http://en.wikipedia.org/wiki/Universal_Serial_Bus

All in all, its a very generic design and you can customise it with 3 or more fans, add more LED's to make it look like a UFO, put 4 rubber bushes on all sides to make it a tabletop laptop cooler etc etc...
It was a fun afternoon and the results were satisfying. And yeah, I managed to save 1500/- during the recession time :-)
