You won't be able to power the RasPi via your computer with it offers 700ma+ over usb, which very few motherboards offer.Dazaster wrote:I have tried 2 or 3 different ways of supplying power via a computer which is on and two different power adapters giving out the required volatage and amperage.

I wouldn't, unless you know what you're doing. Random chemicals, especially general tap water, really are not a good idea. Pure Isopropyl alcohol may be ok (it's generally used in the factory for cleaning flux off).JoeDaStudd wrote: you could try cleaning it with rubbing alcohol and water (alcohol first then water to remove the alcohol).
There's lots of different silkscreen variations http://www.raspberrypi.org/phpBB3/viewt ... =63&t=5889Leo Rest wrote:Just for interest the silk screen looks more like the Farnell board i have eg the wrong font and badly spaced CE mark vs the RS board which only has a CE label stuck to the bottom side.
I know nobody will believe me, but as someone who has spent the better part of 20 years working in exactly the type of electronics assembly factory that'll be building these, I'm quite confident that's no clean flux residue. Not tissue paper, not chalk, just flux.TheCrazyInventor wrote:In my opinion, that doesn't look like flux residue.
I defiantly agree its "no clean flux" but while the residue "shouldn't" cause a problem in itself it is likely to trap moisture which will. Note the dudishous use of quotes!selsinork wrote:I know nobody will believe me...TheCrazyInventor wrote:In my opinion, that doesn't look like flux residue.
I've seen an earlier post saying they are in different assembly lines but has anyone confirmed that they are in different factories?rmm200 wrote:With RS and Farnell running different assembly lines in different factories
