That moment when you know you’re gonna win…
…and you do your little victory dance…
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.
Check the video for a demo:
I’ve never actually been that much into cars but I have a general curiosity on how most things work and this includes the inner workings of vehicles. This golden-oldie video depicts the simple, yet effective, mechanism of differential steering, so if, like me, you didn’t know how this worked…well, now you know.

I know this is old news1, but I guess it’s worth the consideration: asteroid 2011 AG5, an asteroid roughly the size of a football stadium, is thought to be in a (albeit improbable) collision course to Earth.
What happens when you want to start a band and you can’t find just the right partners to play the other instruments? Well, you can use Legos NXT Mindstorms:[youtube http://youtu.be/QwGM-DxJwTg]
I can watch dogs running over a rainbow backdrop.
I can be hypnotized by the hypnotoad.
I can paint virtual nails.
I can see a website that is sometimes blue and sometimes red.
I can check if my computer is on.
I can meet the watermelon duck.
I can turn a light on or off.
I can even go to the end of the Internet.
But I cannot watch some video because some idiot decided that it should not be made available in my country.

However, the use of the Web Audio API (I didn’t want to use MP3 or WAV) for this end proved somehow useless mainly because the sounds it generates are only comparable to those of the good old days of dial-up connections. Moreover, the API is only available (for now) in Google Chrome and Mac OS X’s Safari’s latest version.
Perhaps, in the future, I’ll change it once there’s some more interesting way of doing that and that works across more browsers.
So, for now, enjoy only the visual aspect of the game.
