discordant yet musical whistles

My house in Delhi has a guard that walks around and whistles all night to keep the thieves away. I am still amused by the fact how the entire street comes together and contributes and hires the guard, instead of complaining and waiting for the Govt. to solve their issues, which is slow as heck.

Its like a citizen contributed and distributed parallel police with evolving protocol, when the systems don't work well. Atleast it keeps the societal interaction intact and neighbors talk, which i believe is a good thing- communities being vocal about their issues.

writing this at 3AM while everyone sleeps and guard is awake. 

Word of the day- pokayoke


Poka-yoke (ポカヨケ?) [poka yoke] is a Japanese term that means "mistake-proofing". A poka-yoke is any mechanism in a lean manufacturing process that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.The concept was formalised, and the term adopted, by Shigeo Shingo as part of the Toyota Production System.It was originally described as baka-yoke, but as this means "fool-proofing" (or "idiot-proofing") the name was changed to the milder poka-yoke.

dead or alive? dead after all

the missing airplane shows that whatever futuristic things we might develop, its important to be in the present(+3 seconds to avoid maybe a dangerous cat to attack you).

we propose technologies that 'would touch lives' 50 years ahead, and forget to live in/for the present. either we're too much altruistic or just too busy the rat race of inventing a future that we don't know what will be good for. after all these inventions and industries, has world become a happier place? Not sure. Yes, we definitely have gotten many superhuman powers now, but the fact everyone has those powers keeps us pushing for inventing even more.

--- pause---

for a moment, lets be in the moment, and thank nature at times for it has conspired till this very moment-that we are.

I can't even begin to count the number of sensors/technologies, that plane had one in all, so many lives, so many stories. All have become one with the nature now. In split second.

At times have you wondered, that outside that .5 feet plastic wall is pure destruction- juxtaposed to our belief/realisation- as the beautiful airhostness asks us which wine we'd fancy and we're complaining how low resolution the LCDs are.

Right beyond that half a feet of platic/metal lies a dance of death, that'll freeze your blood, in 5 seconds. Realize?

I dont want to scare you, or myself, so I'll stop. I'll drink some green-tea now and leave for my lab. I have those inventions to do.

RIP all victims of Flight 370.  


According to the accredited mechanical flying rules
the bumble-bee can't fly,
because of its shape and its weight
compared with its wing surface.
But the bumble-bee doesn't know about that
and does fly nonetheless.

Magic is inspiring. For it can light up the eyes of the sad, make the logical person believe in things he wouldn't otherwise. Any piece of art, music, work that inspires others to me seems like magic. For its so simple yet none of us could make it, other than the creator. Like Naqvi

Ink harvester progress 1

That's the version 0.1 of the ink-harvester box design. I ended up designing my own enclosure, instead of using Altoids box, though they're the same size.

-The suction exhaust pulls the air containing soot particles from the surroundings.
-A syringe with 1 way valve is being used as the pump which will push the ink into the cartridge.

Next phase,

- Design the carbon separator using capacitive plates. The air comes in with a lot of dust most of which dust and other particles. The powdery black soot separated from rest is what we're interested in.
This principle is used in Chimneys to reduce the carbon particles injected into the atmosphere.

- Interfacing a small sachet that mixes Isopropyl Alcohol and Gum arabic to the powder. I am going to use this DIY pump design for the constant flow of powder to the system
