Oh ok. This a preview video of SD Premium. Voltage, a transistor and resistors or the key words here. As you can see the voltage sensing circuit is actually connected to the base of the transistor. Just under 1 volts the voltage sensing circuit turns on the transistor base and so now the 5v ref can pass through the 1K Ohm resistor instead of the 10K Ohm.

It's better to post this in the 'ScannerDanner book and lecture video questions' Inge. Not trying to be annoying here. On the new forums we'll be able to move threads ;-) It'll be easier.

A few weeks away Dylan! Unfortunately none of this is coming with us, so at this point it really doesn't matter. Thanks bro
