20x20mm fans

[JamieLee2k]

Went to Maplins to find an alternative power supply.
I eneded up buying a resistor to bring the 9V to 5V.
Soldered in-line on the live to/from the battery.
The pictures show the components;
Fan=17mm x 17mm A25GU@£4.99.
Battery box=L90AN@ £1.29.
Resistor=M51R@£0.15(worked out as a 50 ohm which they don't stock,51 is ok).
Of course you need solder,heat shrink,cable ties(2.5mm),drill bit 2.5mm.
I'll do step by step pictoral breakdown later in the week(after I've finished nights),it is very easy.

Fan,box and resistor.
Resistor.....

This is the way to go, now I have seen a picture of the size of the fan I now know this is the correct one, I will get my bits when I get paid end of month

Cheers mate!
I was just involved in searching for exactly the same stuff (After seeing a graphics card fan for sale as a mask fan on shebay)
Just used your order numbers and placed me an order!

Fan and battery box ready to be fitted.
The resistor is just out of the picture about 2" from the battery box.
Fitted.
You can see the resistor.
Fan close-up,held with 2.5mm cable ties.
