Hi All,
I want to build this circuit to install in a laptop tray in order to reduce & control the heat of a rather expensive laptop which I acquired recently.
I am finding it rather difficult to source exactly a 200ohm SPST relay as required in the circuit, hence wonder if a higher value of say, a 700 ohm will suffice? The fan has a current consumption of 250mA.
My knowledge of relays is rather limited, so any further advice or tips in choosing the right value would be of great help! I have not constructed the circuit yet, so any further comments on it's merits or flaws would be most welcome
Thanks
