Re: Power cable problems

What voltage do you get at the output of the power supply when not attached?

What amperage is the power supply?

With the power supply attached what reading do you get across TP1,2?

Have you tried a different manufacturers SD card?

Re: Tip if your HDMI doesn't seem to be working

Well yes. The power supply is sealed, and I don't feel like breaking into it just yet. It is switch mode though, so something is causing it to go out of regulation.

I've had the hub apart for a cursory glance, two hub chips and some glue components. H

Re: Trying to get an RTL8188CUS wireless USB NIC working.

I found the Fedora 14 Remix-r1  install found my RTL8192SU WiFi adapter, but Debian 6 19-04-2012 didn't.

Unfortunately I can't even attempt to do anything with Debian as it wants the root password, which I don't have.

Yes it is, the polyfuse (according to the schematic) is rated at 6v so allowing for a margin of safety I'd not want to go higher than 5v25.

It would be interesting to know the voltage at RasPi for each power supply.  For example, a higher voltage could cause RG2 to run hotter which could cause a marginal F3 to misbehave.


RG2?  What component are you referring to?
