Towards a Better Mask – 3

An internal project under Rattl has been to try create a better mask for the (Covid) times.

While it is possible we fail to actually create an ideal one, the exercise so far has been a learning one.

This is post #3.

Post 1 listed some basic criteria and good to have features that served as guidelines/constraints and some initial sketches.

Post 2 factored in all the basic criteria and most of the ‘good-to-have’ features, in that it was transparent (though slightly off the mark) and had reasonably good circulation.

Based on the basic criteria, good-to-have features and general observation of regular folk preferring a handkerchief to a mask (walking through markets, handkerchiefs seem to be a preferred choice, especially for those needing to wear it all day), the next prototype has the following:

  • Addresses all basic features (though I didn’t have the time to cut out a section so it fits better around the nose)
  • Safety (basic criteria) is far higher than a handkerchief
  • Regarding ‘good-to-have’ features, it wasn’t transparent, but circulation was probably better than with handkerchiefs

What it is, is a section (slightly less than half) of a takeaway plastic soup bowl between the folds of a regular handkerchief.
Used a mini vice to hold the bowl in place, and cut it with a rotary tool.

Since a good number of people prefer a handkerchief (possibly due to convenience and affordability), but are probably not aware of the limited safety provided, this design simply offers a safer handkerchief.

Strings from the bowl (how about call it mask henceforth? 😁) run along the ends of the handkerchief folded in half (how people normally fold it before tying).
How it is different or safer than regular handkerchiefs, is the plastic over the nose and mouth section prevents any direct spit/particles from anyone nearby landing on the handkerchief from passing right through.

The bulge creates breathing room, something both handkerchiefs and regular masks don’t offer, and which is what causes a lot of people to slide them down or stop wearing them – the suffocation.

The small breathing space offered by the curvature of the bowl makes it more comfortable to wear, and the bottom section of the handkerchief can be partly folded into the bottom section of the mask, to allow for better ventilation while not giving direct exit to any germ from the user.

Let me know what you think!

Towards a Better Mask – 2

An internal project under Rattl has been to try create a better mask for the (Covid) times.

While it is possible we fail to actually create an ideal one, the exercise so far has been a learning one.

This is post #2.

This was part experiment, part fun. I’ve always been fascinated with the idea of using car components for things. For instance, a dream is to someday replace the sofa in the hall with car seats.

Back to the topic, affordability comes from using empty soup bowls from an earlier food delivery. 😛 

As for the funny white extensions on the sides, they are cardboard (from some box) and inside it lies the “protection” – A decent quality car air-conditioning filter. The entire AC filter comes for a few hundred bucks, and I barely used 10-15% of one. There’s a section of folded filter, and a second single layer where that white section joins the s̶o̶u̶p̶ ̶b̶o̶w̶l̶  mask via a ~1.2 cm opening [below].

So that’s double layer of protection! The plastic section wouldn’t allow the virus in. And the front is transparent to allow for better human interaction. With this particular prototype, the nose cut-out was not deep enough so the transparent section focused more on the beard, but ideally, it would give a view of the mouth and part of the nose.

If you’ve seen the criteria listed in the 1st post of this series, this one prototype addresses:

Among the basic criteria:

  • Protection
  • Affordability
  • Partly achieves ‘breathable’
  • Addresses gaps on the sides of the nose

And among Good-to-have features:

  • Transparency (almost on this one, but should be easy to fix)
  • Partly addresses good circulation (by being a few centimeters away from the mouth and nose, it allows for a more open, relaxed breathing setting as opposed to most regular masks)

Of course the air filtering packs on the sides are huge and unwieldy. General comfort too wasn’t great as I simply used the elastic bands from a used surgical mask so it was tight (to the point it almost took my eye out when the nose protection cushion slipped out and the strain of the bands pushed the jagged plastic edge in my eye as I was fumbling around trying to take a selfie with the mask on.

Anyway, till the next prototype…

Books Recommended in Books

I mostly read only ebooks since a few years now.
A lot of good non-fiction books usually mention a few more good books that the authors found relevant. However, even if you highlight them as you read, it is tough to find the names later on. Especially if you didn’t make a note of them. You’d have to go through the book or highlights to find those names again. Before you forget.
What if authors did one of the following:
  • Used a common phrase each time they referred to or recommended a book in their book. Something like ‘XYZ, a book written by ABC’
  • Or separately list out the books at the end of the book
The latter would help both physical books and ebooks. The first would help search for the specific phrase (“a book written by”) in the ebook, thus turning up results of all the books mentioned in it
Now all that needs to be done is suggest this to authors, and to remember it myself if I ever get to writing another book.

Zomato’s Vertical Slider

Zomato has a really simple but brilliant vertical filter slider.
Many sites and apps aren’t great when it comes to their filters. And oddly, most who use sliders have horizontal ones.

The problem with horizontal sliders on mobile apps, is that we are usually using our phones with one hand. And horizontal slider options are a strain on the thumb. Vertical sliders are simply easier to use. It’s odd how most other apps still use horizontal sliders.

Might not be long before others copy it; but nice work, Zomato!

College Industry Projects

College students and college staff love industry projects. They give students an opportunity to get a feeler of what life after college will be like. Barring any major screw-ups, it is relatively free of the accountability pressures that full-time employees experience. And if there’s a stipend involved, what’s better than that, right?

Consider this…College ecosystems are increasingly focused on industry. And obviously so. But given a choice, every subject project would be an industry project. Top that with b-school obsessions with finishing school type skills to ace interviews. My own MBA program that I’m not too proud of, involved mostly visiting faculty who were really good at what they did, but for many of them, the concept of teaching was something like this… Early in the sem, they’d create ‘x’ number of groups out of our class. Then they’d take the syllabus, chop it up into ‘x’ topics. Each group would present a topic during each lecture. Convenient, right? A more relevant phrase that always comes to mind is, ‘the blind leading the blind.’

So for the heck of it, if we were to plot this trend of live projects forward, colleges themselves would become redundant. Since education exists online in far more affordable, consumable and convenient forms.

So is there something that can be taught at colleges that is tough to learn elsewhere?

I’d say values. Principles. Ethics. Interdependence. Servant leadership. Etc.

My concern with live projects early in a student’s college life is that their entire concept of industry work life gets influenced or shaped by their live projects. And if their value foundations aren’t strong enough, we get the kind of mess a lot of leading business schools (think ‘bar-word’) have created. The sole focus on sales and profit at any and all costs. The global environmental crises, deforestation, corporate glass ceilings, unequal pay, workplace harassment. This about one Harvard dropout Mark Zuckaberg’s moral compass with Facebook. Soak in the irony for a moment. Facebook and Cambridge Analytica conspired to rig elections around the world. And in 2017, Harvard University, based in “Cambridge” Massachusetts, awarded Zuckaberg an honarary Doctor of “Laws” degree.

I believe the first 1-2 semesters in any college should be more about building morals leadership with an industry perspective, rather than simply taking students and tossing them into the “big bad world”. Because it isn’t so much about learning skills. Those are easy to pick up on the job. But few teach you values in the industry. Do you want to leave your student’s future to that chance?

Behavioural Law

Classic economics started off factoring psychology and behavioural trends and shortcomings (biases) into economic understanding. However, through the ages, economic concepts and policies were built on the assumption that humans are rational beings. This was like putting a blanket over our susceptibility to biases and our irrational decision-making tendencies.

It took the path-breaking decades of work by 2002 Nobel Laureate (Memorial Prize in Economic Sciences) Daniel Kahneman, Amos Tversky and a few others, to identify and document common human mistakes that spring from our heuristics and biases. This led to the importance of the field of behavioural economics which should ideally replace all economic skillsets.

Going by that logic, I did a cursory check on the LLB syllabus in India and that at Harvard Law School. I also came across research papers and articles around behavioural law at institutes like Yale, Harvard, Cambridge. However, a generic search for Indian LLB syllabus and the Harvard Law curriculum did not show up any subject dedicated to psychology, behaviour, or behavioural law. Stanford mentioned it. However Yale Law did have a fair bit of behaviour covered.

Harvard Law curriculum

While the Harvard program had some 55o study modules, and while they certainly might be including aspects of behavioural law, the subjects list did not include anything related to it or behaviour, despite the importance one might associate with it.

One would imagine that given all the business and personal collaborations and disputes that occur across the world, institutes should have at least by now made human behaviour, behavioural economics and psychology a key part of learning.

You might wonder what it might include? While I wouldn’t exactly know how, I do know that legal professionals are well trained in attack and defense, both in documentation and in fighting cases. And they are adept at understanding the opposition for defense or attack; and identifying potential risk scenarios well into the future. However, armed with behavioural knowledge, they might be able to influence collaborations and solve disputes amicably simply with a better understanding of behaviour and therefore a better choice of words and strategy perhaps. One that could benefit all related parties themselves fairly in the short term, but also steadily influence a more collaborative human race in the longer term.

Many of us have seen those videos of Providence, Rhode Island’s chief municipal judge, Francesco “Frank” Caprio, who metes out ‘human’ and ‘humane’ justice. Someone receiving a judgement from him, or someone simply being spectator to his judgement might have a very different view of humankind. One that is compassionate and optimistic. In a world itching to accuse and punish, imagine the mindset change an entire global legal fraternity might bring about, if they had the superior maturity of Judge Frank Caprio.

Matchbox Design

Matchbox design

As a kid, I used to be quite fascinated by matchboxes. From the uncertainty of being shouted at by some elder, to how many tries it took to light it. And the best, how long could you hold a lit match without burning your fingers.

Pic source: link

Back then, the SHIP matchbox was commonplace. Though I don’t remember them having the jokes at the back of each pack. This standard pack had 50 matchsticks in it. A common problem with any matchbox is running low on striking surface towards the end. It takes more attempts to successfully strike a match.

Then, HomeLites came out with a significantly bigger matchbox. These had 300 matchsticks in it. These seemed to have a bigger problem with the striking surface. Maybe it was the longer striking surface strips on each side that led one to make longer strikes. As a result, you’d have a lot of matches left, but striking a match would become increasingly difficult. You’d spot some unused section towards the edges and try striking it there.

Pic source: link

Anyway, recently I noticed a tiny design change with their matchboxes. And I think it might just solve the striking surface problem.

What they simply did, was replace the two long striking surfaces on either side of the matchbox, with a tiny dividing strip. So instead of two long striking strips, you now have a total of four smaller strips.

If you are overly disciplined, you might restrict yourself to one striking surface at a time. Then use the next one. The rest of us will randomly strike a match against any one of the four surfaces. Point being, with the shorter striking surface, we will unconsciously limit our strike action to that stretch. Am quite sure these new boxes won’t have that old problem.

Just an example of how a simple change to the matchbox design solves a problem that might have left many puzzled. A tiny break in the striking surface alters user behaviour in the right direction. And without necessitating any complex redesigning of the matchbox itself.

If you want to know more about exactly how matches work, read on…

[source of the excerpt below: link]:

The heads of safety matches are composed of a single part. They contain antimony trisulfide, potassium chlorate, sulfur, powdered glass, inert fillers, and animal glue. They may also include a water-soluble dye. Antimony trisulfide cannot be ignited by the heat of friction, even in the presence of an oxidizing agent like potassium chlorate, and it requires another source of ignition to start the combustion. That source of ignition comes from the striking surface, which is deposited on the side of the matchbox or on the back cover of the matchbook.

The striking surface contains red phosphorus, powdered glass, and an adhesive such as gum arabic or urea formaldehyde. When a safety match is rubbed against the striking surface, the friction generates enough heat to convert a trace of the red phosphorus into white phosphorus. This immediately reacts with the potassium chlorate in the match head to produce enough heat to ignite the antimony trisulfide and start the combustion.

Heard of Jane Elliott?
She’s an American schoolteacher and an anti-racism activist. She is especially famous for her truly visionary “Blue Eyes-Brown Eyes” exercise that she conducted in her classroom, 50 years ago.
Get a quick overview of her Blue Eyes-Brown Eyes exercise here. I first came across this a few months ago and thought it was exceptional.
Now, Jane recently spoke about world maps, racism, and a bit about her childhood. The stuff about maps really shakes, or at least shook my foundation about maps. Like me, you might just ask yourself what in the world is actually true, if something as fundamental as a map could be distorted that much.

What an inspiration, this woman is!

Vertical Stapler

Vertical Stapler

Image: source

Over the years, I’ve found myself wanting to staple certain paper prototypes in a particular way. The standard stapler would not allow it though.

One early need I found for a better stapler was during my venture capital days. In an effort to reduce paper wastage, whenever a draft review report needed to be printed, I’d use the book format print option available on the office printer. The printout then just needed to be folded down the centre. You then needed to open the stapler arm, put it along the fold, and press. The ends of the staple pin popping out on the other side would then need to be folded in. Having a vertical stapler (if there is such a thing) would have been so much more convenient.
Why? Because it would allow you to slide the stapler along the fold, and staple. The current design would not allow you to reach the centre fold to staple without opening the lower arm.

What’s even tougher, is when you need to staple the ends of a paper cone. A few different prototypes have had paper cones as part of it. The stapler just wouldn’t reach anywhere near the tip of the cone. Here, a vertical stapler would be very useful.

But when you think about it, the existing stapler design would not work for a vertical stapler. In the regular ones, the two ends of the pin make contact with a surface at the same time, enabling a symmetrical clip being formed.

With a vertical one, using the existing design, one end would make contact first, and this would most likely deform the pin before it is punched in.

Then I came across this interesting D-I-Y article for a vertical stapler.


One alternative would be where the mould section of the lower arm of the vertical stapler is tilted upwards a bit to enable uniform contact of the two ends of the pin. However, that too would not help with accessing tough-to-reach areas and staple them. Perhaps if the finger grip moulds at the end were gotten rid off and the arms of the stapler ended slightly more pointed, it would allow a better reach.

Seen anything even remotely similar to what I described? Or can you think of any alternate solutions for stapling tough-to-reach areas on sheets of paper?

The ENGESA Mercedes truck

I recently saw this video of a ENGESA Mercedes truck. Something obviously very fascinating about it. So I thought I’d attempt to recreate it in some way, using Lego. This is a quick, crude first attempt. I clearly don’t have enough relevant pieces.


Below was an improved variant to the earlier one. The last model was built simply to see the beauty of the multi-axle movement. But the last version hadd traction/ground clearance issues, as the wheels would hit the undercarriage at certain tilts. So I went a step further and replicated the rear multi-axle on the front too. And, the cab roof sloped up (for better aerodynamics).

And, a final variant of my idea of an ENGESA Mercedes truck, before I was done with this concept. This one has a double swivel multi-axle and a horizontal swivel link after the cab, to allow it to turn better.
