I have heard that you are able to get speed information from a DC motor 
without using encoders. Here is an article that tells how to do it.  I have 
not tried it, but what he says makes sense.

You can not use this for precise position, because he says the pulses are 
not even around the motor.  But there is a consistent number per revolution.
