Singapore Mini Maker Faire Part 1

I went to the mini Maker Faire at the Singapore Science Centre.

In the video, there’s a device that measures distances using ultrasonic waves, and based on that, turns a light on or off. It took me a while before I finally understood the concept. I thought it was directional, because she explained the device by pointing it up and down for light-on and light-off. Then I asked if it could be programmed to understand sideways directions…

Basically, if you block the emitting device (ultrasonic waves) within a certain distance, the light switches on. That’s why pointing to the ceiling switches it off, because the distance between the device and the ceiling exceeds the programmed distance limit.

In this issue of Singularity, you’ll read my interview with Dave Doolin, who writes at Website In A Weekend. We talked about the US economy, the prospects of being a generalist in Singapore and WordPress. He’s also on Twitter @websiteweekend.

And if you haven’t watched it, I also explain the maths concept of Cantor sets in a video. Harry Potter references and special yellow screen effects. Watch it. Now.

You’ll also read about the second part of my visit to the Singapore Science Centre. There’s a special section on optical illusions. See if you’re stumped.
