Hi all,
I've got one of these..... http://www.dealextreme.com/details.dx/sku.14450
I've ascertained that if I upgrade the led to an XRE R2 the existing resistor should work... it has no driver, however somehow whilst fiddling around around with a soldering iron - I've blown the resistor. Can anyone tell what I need to replace it with? Looking at the colour bands, and using an iphone app. - I've unconfidently concluded that it was a 0.21 ohm resistor - but my local electronics store didn't have any. Does that sound about right? This is all very new to me....
Still not quite sure how I blew the thing in the first place...
Thanks for your help.
