This is a wonderful story - and one that I managed to miss until reading it in EETimes. Such public displays open up conversations that otherwise would not occur. I'm also impressed by the advances in skywriting freom what I'd previously known.  The ability to make a message quickly is essential to achieve legibility.

355/113 is another good fraction that is accurate to the 6th decimal place.

It's very cool. I wonder when artist will start using Drone to paint art in the sky.

Apart from smoke generator, airplane need fuel to drive thier engine. 100LL aviation gasoline (AVGAS) still contains lead (LL is short for "Low Lead") - not exactly eco-friendly :-( It has been long argument when / how do we transision from AVGAS to something else, and what is that "something else". Automobile gasoline, methanol, diesel has been proposed but not widely adopted yet (FAA certification is costly and time-consuming).

It is interesting to hear other "Integer substitution of Pi", 22/7 and 201/64. I will put them in my toolbox. Slide rule and 8-bit CPU days are fading, but I may need them someday, just in case :-)

Just imagine how many vegetables were used to produce this vegetable oil.

I wonder how much this cost. Pretty clever --  a lot of coordination must have gone into this.

Agreed!  The more I hear about the necisity of adding a fashion component to wearables (and fashion can be art!), the more I think about STEAM v. STEM.

If you're dealing with a simple processor and integer math, 201/64 can use bit shifts for divisions. You can use Num * 201 >> 6 (divide by 64)  or Num * 201 << 2 (multiply by 4) and drop the low byte.

 There is also 3217>>10 but you will need to have large enough variables to handle the 3217 multiply.

Totally, totally cool. I wonder how many people knew what they were seeing when they looked up at it?

NEXT UPCOMING BROADCAST

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
