[Jenny] and I were talking about [Bitluni]’s experiment in scale, where he will take 65,536 cheap microcontrollers, network them all together, and give each one an RGB pixel. From there, antics will surely ensue. Right now, he’s only got 8,192 of them up and running, and already the novel problems and opportunities are rearing their heads.
We all know it from our own hacking. In theory, doing something ten times is ten times doing it once. But then in practice, entirely new phenomena appear as you scale up that were simply not there in the small. Maybe it happens when you repeat it one hundred times, or a thousand.
Viewed positively, this is the property of emergence: how the whole can be more than the sum of its parts, and how biology isn’t just chemistry multiplied by a few million interactions. In our blinky world, a massive wall of LEDs is a display, not just a bunch of pixels.
On the flip side, going from one microcontroller with a 10 mA current draw to 64 Ki controllers, with 655 A, is more than just a difference in scale. You need to learn a new skill set to handle the problem. Making a single prototype is a different problem from making a run of badges for a conference of 5,000 – you’ll need a team, and won’t be able to just hack it alone – not to even mention the parts sourcing woes.
So I loved watching [Bitluni] going through the upscaling. He certainly had an idea of what he was getting himself into, but as with the emerging properties of a big system, there are often emerging problems, and those you can’t always see ahead of time. Have you gotten into a project that scaled itself into something qualitatively different? Tell us about it.
