Using a transistor to control a motor?

Grumpy_Mike: Have you seen this? http://www.thebox.myzen.co.uk/Tutorial/Power.html and http://www.thebox.myzen.co.uk/Tutorial/Power_Examples.html

Wait when you said work it out, what did you mean? Did you mean to convert the chip tempurture to case tempurture or did you mean to just use that chip tempurture and work it out?

Thanks! Tyler
