These are the new Rotacaster wheels that arrived Monday morning. The one with the orange hub has dark grey, soft, very grippy rollers; the wheel with the dark grey hub  has slightly harder, orange rollers. These are the latest prototypes and they have undergone some great improvements; the rollers roll more freely and the hubs grip the axels in a ...

After seeing the video posted on Mauro Brunato’s website, I got all sorts of ideas in my head for other cool things to do with it. With a little help from my friend SC, I managed to get my hands on one of these Kinect sensors as well. It wasn’t easy to get it working, though but with the help ...

Dexter Industries have been very busy with their latest creation: a WiFi sensor for your NXT! I have one of them en-route to me as I write this, so as soon as I get my hands on it, I will let you know what it’s like.  I already have some pretty cool ideas for it in mind. I don’t know ...

Please keep in mind a few things: Do this at your own risk This won’t work with sensors that require 9V to operate This won’t work with analogue sensors Do this at your own risk You will need the following: ...

The VEX Cortex is a nice platform made by VEX Robotics. It is supported in two programming environments, one of which is ROBOTC. Much to my dismay, the master firmware does not support I2C, which is why ROBOTC does not support it. I don’t really like it when someone tells me I can’t do something, so I went ahead and ...

After more than 2.5 years, I’ve decided to change the old theme for a new one. It took a while before I found one that agreed with me.  This one is not too busy and has a nice high contrast.
