I’ve never been a petrolhead and engines, in general, have always been a mystery to me. Then I found this beautiful set of animations that explains the whole thing.

Fully recommended!

I thought about creating different ways to control a toy car in a race track, instead of the typical handheld joystick-like device. One of those ideas was based on the use of a sonar (that measures distance to an object) as the controller for the car – the closer the hand to the sonar, the highest the acceleration.

However, considering that the sonar works through eco-location and that the track makes an infernal sound, the sonar accuracy is affected by the sound of the track, thus rendering this approach useless.

Any alternative ideas? I will try the best one (as long as it is not cost-prohibitive) 🙂

When I was a kid, I used to do these spinning paintings using a small motor (salvaged from a broken toy car) connected a 9V battery with a piece of paper on top. The effect was mesmerizing and I had fun for hours.

Last week, given the amount of hardware I gutted for parts (for a digital fabrication workshop), I ended up with a bunch of different motors and that brought back those memories. So, I decided to do the same setup again, this time using an arduino (to easily control the speed given to the motor) to see if my son would find it as amusing as I did.

And so an era ends.

RIP Google Reader

I’ve been using Feedly as an alternative because the mobile apps are quite good and the website is a “prettier” google reader. And they actually listen to the users and implement requested features. Also, it seems my Mac RSS app of choice, Reeder, will soon have support for it, so I probably won’t miss Google Reader that much.

What happens when you leave 16 autonomous AI bots alone to play Quake 3 Arena against each other for 4 years? Apparently, they play the ultimate Cold War game and achieve “world peace”.

I don’t know if this story is true or not, but it actually makes sense from a purely logical self-preservation point of view. The bots were programmed to study which strategies were more efficient in guaranteeing their survival. After a few years, they probably realized that the best strategy is actually to not engage each other and they all win.
