Re: The XKCD Book Thread

My copy of the book just showed up!

The pages are numbered in trinary!

There is also some form of cipher in the annotations. I haven't had a chance to look more closely though...

Awesome book Randall, can't wait for volume 1 :)

Re: Blackberry Cradle.

It is possible that they're using some form of induction to "sense" the cradle without needing external contacts (can it sense the cradle if you put a piece of paper between the blackberry and the cradle? If so, it's probably induction based.

Re: Graphing Calculator locked up

There is a second battery pack on the TI-83+ (And presumably on the others too). It's behind a small panel with one screw in the main battery pack and holds a coin cell. Try taking that out too.

Re: Building a Mapping Robot

I would warrant against using a single encoder on one wheel though. The reason for this is you cant really tell if you are going in a straight line, even though this is damn hard anyways. I would like to reiterate that a gyro + one encoder would work as well to tell distance and heading. The other ...

Re: Building a Mapping Robot

I would say you should add an encoder to the non-powered wheel and also add a gyroscope: The encoder will allow you measure the actual distance traveled, so you don't count "steps" that were taken with the powered wheel spinning faster than the robots actual movement (slipping). The gyrosc...

Re: CMOS Checksum Error?

The "CMOS Checksum Error" occurs because the CMOS maintains a checksum (like MD5) of itself so it can quickly check to see if the CMOS got corrupted. A checksum error means that the CMOS thinks that is was corrupt (the CMOS's current checksum doesn't match the stored one). As long as this ...

Sounds like the driver failed to start (you're running in software emulation mode). Try re-installing the drivers. If that fails, just install the old version of the driver.
