12V Fan off 230v power supply ?

[irving2008]

if you want a cheap design you can make yourself then thats easy too, see diagram...but it'll prob cost a little more than the ebay option... doesn't need a circuit board. transformer and rectifier bolt down and capacitor can be soldered directly to rectifier leads and input and output wires just need restraining with some cable clips. Will power 4 - 5 small fans, or 3 large ones
