03 – The Side Table

Once I cut through the block of pine that I had used for my shape optimization tests. I think I got in the groove where I wanted to make more tables. In the last two weeks before my departure for home, I built a small side table with a walnut top and pine legs.

It is a simple design inspired from the form of a temple gate or torana. Lightweight and portable, it can be placed in a corner or along a wall and can find use as a nightstand or as a surface on which prayer items could be placed, or even just as a decorative piece by itself.

I decided that this handcrafted piece would make a great gift for my friend who would be getting married by the time I reached India. The table fit perfectly in my luggage in between the rolls of clothes and safely completed its journey of a bus ride and two international flights. I am glad that it was received well and now occupies a corner as one of the first furniture pieces in their new home.

Post-Sensory

They have managed to nail computer vision, and the abilities of machines discern sounds and create speech are better than ever. Presently, the focus has been on the sense of touch – and the interfaces are focusing on the tactile, trying to refine it and give it the quantity (and at times quality) so that a machine may experience it the same way. But taste is what I want them to define next to a machine.

Computer Taste. Taste Recognition. As absurd as it sounds.

Vision and sound have probably been the easiest of sensory experiences for us to mechanize and digitize.  Taste, I feel, shall probably be the last and the most difficult of all senses to replicate. Even with the most refined of present sensor-tech we have created that can detect and quantify a change in the natural world, taste is something at a higher level, it is a combination of the other senses. It is where the touch, smell and vision come into play together. Even with combinations of individual sensor-values affecting brain activity for each item tasted, what we would be able to create further from a model trained on this would only give us the brain activity equivalent, and it would not be replicating the sensation itself.

But maybe it will be possible one day, when the total sensory input gets strong enough to surpass taste, where taste is not necessary as a more powerful sensory dimension would exist in its place and be much more useful to an artificial super-intelligence. It would be like tasting one’s food by just by the sight or smell of it, like how we do countless times in passing.

That sensory dimension sounds a lot like desire.

It must,

This glacial pain of the mountains

Must melt,

An outpour Gangetic,

Something pure and holy.

 

They must,

These walls, these concrete curtains

Must tremble,

Behind them we yearned

for quakes, not storms

 

It must,

In streets, alleys, cities and hamlets

Must march,

Every corpse, as the living

A dance fervorous.

 

They must,

These times

Must change,

In this influence,

My only offence.

 

But she must,

In our hearts

Must burn,

This fire

If not in mine, then in yours.

New Light On Dancing Shiva Symbol

This is a review written by my father which was published in The National Herald on 08/06/1996.

[Dancing Shiva in the Ecological Age: By Henryk Skolimowski, Publisher: Dr. Henryk Skolimowski, International Center for Eco-Philosophy and Indian Institute of Ecology & Environment New Delhi. Paperback. Pages: 214, 1995, Price: Not Written]

The collection of articles by the learned author who is a Professor of Philosophy in the Programme in Humanities, College of Engineering, University of Michigan, USA, is an attempt at giving a new meaning to the dancing Shiva symbol so commonly available in the Hindu temples, Hindu households, museums of arts etc. Although in the Hindu religious mythology, Shiva is one of the Trinity responsible for destruction preceding a rejuvenation, the author tries to cull out the basic essence of Hindu philosophy in which destruction is never final and creation is never complete in the sense that they are all part of the same cycle in which there is no beginning or end.

2. The author has quoted profusely not only from Upanishads, Buddhist literature, Christian theology but also from the present day savants such as Andre Malaraux and T.S. Eliot. The vastness of the range and the depth of the author’s learning is also evident in his mastery of language and ability to use the words as instruments of revelation.

3. Although the volume contains 15 articles each of which can be read independently yet there is a common theme running through all of them. The theme is that man’s relationship with nature should be that of reverence, love, devotion and not otherwise. According to the author, participation at the deepest level is the true essence of life.  there is an interesting article on structures, symbols and evolution. The author describes in some detail what the dancing Shiva symbol of Hinduism means to him.

It is a symbol of continuous metamorphosis, a ceaseless beginning of life, a symbol of fluidity and essentially undefinable character of life. There is something fascinating and mysterious in the conception of universe conceived in the image of dancing Shiva. It is this conception that some of the Western thinkers (such as F.Capre) have evoked to replace the petrified conception of the universe in the image of the Neutonian clock.

4. an abstruse book which could be understood only by a person having reasonable proficiency in philosophy and metaphysics, it seeks to emphasise the wholeness of the universe and oneness of life manifest in plants, animals and human beings.

The author seems to be a votary of Hindu view of life which underplays differences and divisions and accentuates oneness and wholeness. The author feels that the dancing Shiva symbol enjoins upon mankind to feel responsible for the nature and the universe, the responsibility of which will result in the rehabilitation and protection of everything that is good in the world and in turning good of whatever is not.

One could disagree with the author but one can not help feeling moved by the sense of urgency that drips from every paragraph of the book. The author feels that we had better get together our acts including our pursuits of ‘scientific knowledge’ otherwise it will be too late.

Seat Frame: Shape Optimization Test

I wanted to put Autodesk Fusion360‘s Simulation feature to work. I decided to create a block that supports the three legs of a stool and ran the space optimization study over it. Using a plastic like ABS in the simulation and MDF for the legs, I could get an estimate of the stress-contours (best among woods and plastics). I used these as templates to remove excess material and decided to 3D print a piece, a slide in joint/frame for my seat.

Now this is the step which is not the right way to go about testing a part for strength – since plastic has a non-linear Young’s modulus and 3D printed parts are neither really solid nor with uniformity among the layers, FDM is definitely not the way to obtain a test piece (however SLA printed parts fare better in this). But I did it anyway, to see how much this shape could take with a ten percent infill just with the defining walls on the outside making up this part – would anyway be a good indicator.

Surprisingly, everything fit well and the seat was able to take my weight, but because of the lack of joinery, it would wobble and slide out of the fixtures with any movement. So, as a way to keep this piece serving some purpose, I just applied some wood glue to the dowels and jammed them between the legs and the top.

For future, this frame could incorporate a clever locking mechanism for the legs and maybe have a smoother, more organic surface without the very much visible fillets.

Quick Build: Piezo-Pickup Casing

Months ago, when my roommate managed to buy a sweet Fender acoustic guitar from a student who was moving out, I mentioned that he get a piezo-electric pickup. We found the cheapest one on Amazon for about ten dollars, and after receiving it, we realized that we had no way to secure it to the guitar maybe apart from drilling a hole through its body for the output jack. So, the project lay dormant until yesterday. I love small projects like these where excess material can find some purpose.

Sunday – just pulled out a block of pine from my box of materials and took some measurements of the pickup’s components.

 

Monday – managed to cut a casing with just those measurements (without the pickup as the reference) only to return home and find that some of my estimates were way off.

Tuesday – tried to make this casing again from scratch, having the pickup with me for reference helped cut down the time considerably. Upon coming home, I attached the casing on the guitar with velcro and then decided to utilize the previously failed piece as an extension to it (so that it has more area to stick to and is easier to remove and attach). I plugged in the pickup to my processor and it sounded pretty damn good across most patches. Also reinforced the original wire by wrapping it with really loud “Chenille Stems”.

Wednesday – Glued the previously failed piece to the new casing, sanded down the faces and put some wax to make it shine. Invited my friends to try it out on Friday.

 

Departures

September 2013

The Ganges roars, a wind above it in this night, dragged along with the torrent that made the hills echo only a few hours back. Nothing to be seen beyond what the floodlights show of this concrete bank, this ghat is like a train station drifting through the night. The platform where the last goodbyes are said. With a vessel in my hand, I step into the cold water – coldest thing to be out there in this summer, my bare feet are pierced by sharp rocks. There is a clinker that can be heard through as my feet drag through the steps. Bones. Thousands of pieces accumulated. The ticket stubs left by countless who left from this spot. I think of them, try to fit all their lives within a moment of closed eyes before I offer the remains to the river. The river swallows them readily into the grander offering which is the garland of bones under these muddy waters.

Of Dogs & Mountains

Whenever I have hiked in any part of the Himalayas, there has always been a dog that tagged along. And this is something everyone experiences – anyone who has taken a trail leaving a village or a town. The reasons will not be known as to why these mountain dogs accompany travelers in their treks from one village to another, only to mysteriously disappear and reappear again. Maybe they do it as a duty or with the hope of getting some food; or for their own sense of security, to have a human to walk along with through these isolated paths that might harbor some danger. These dogs are the much-mentioned, often-photographed but seldom-discussed aspects of everyone’s Himalayan journey. Their stamina will surely surpass yours and they could do the same trek several times in a day, both ways – your challenge is their neighborhood and one should never forget that. Their friendliness comes from seeing this world right from their doorstep – these are wise beings that must be treated with respect.

Climbing right now, my legs hurt and these urban lungs gasp for the very cool air that makes my ears hurt, and I slump down on a rock to rest. If I climbed too fast, the four-legged friend will come trailing along, I ask him whether it was the flower in bloom that slowed him down or if it were the bones in the grass I had quickly glanced over; if I climbed too slow, he will be up there ahead of me, gazing from some vantage point waiting for me to start again.

In the towering silence of the mountains, away from humans, I become aware of this other being’s presence and the trust and familiarity we have in this short duration of knowing each other. Briefly, I understand what Yudhishthira might have felt when asked to let go of the dog at the end of his climb to the heaven. And maybe the dogs that climbed with me (and you) were indeed Yama in disguise – who knows? But anyway, a part of this story about the final test of a demigod repeats in each and every such climb; staying alive as long as there are dogs, mountains and men.

Flood Protection For Automobiles

The changing global climate shows up every year with its stronger than ever hurricanes and floods. A major section of the world population resides along the coasts or such major water bodies, and it is common to see a flood happening somewhere in the world at any given time of the year. What I saw among that property damage were the perfectly good vehicles, sometimes new ones still in the dealership lot, that have been ruined and will probably end up in a scrap sale or clearance auction.

This is a design for protection of vehicles against floodwaters. It is an inflatable device which is first spread under the vehicle like a mat and then is inflated to keep the automobile above the water level. Material must be chosen to make it last the longest duration of floods. These floating devices are ribbed under the surface to provide protection and strength. Other than their primary use, they can also be used as boats to transport goods, people and rescue material. There could even be a mechanism which inflates these via the car’s exhaust system. As it can be deflated and stored in the trunk or in the garage – it is an easy to store and quick to deploy system.
