Re: Playing with mains, how to sense 220v input -solved- I

I wouldn't use that circuit, it could easily kill you or your Pi.
Presumably you're going to be running the Pi off a battery, and the battery will be charged from the mains? If so you've already got a safe isolated supply that you can monitor to see if the mains has gone down.

Wheezy Beta won't boot with HDMI connected

Here's a weird on for you :) As the titles says the Wheezy Beta won't boot for me with the HDMI lead connected, the power light comes on and OK flashes a couple of times and then it just sits there. If I power it up without the HDMI lead it boots fine, if I then plug the lead in, ssh in and reboot i...

Re: Problem with memory (not ram)

The image is basically a copy of a 2GB partition, so that's all you see what ever size of SD card you write it to. Follow the instructions here http://elinux.org/RPi_Resize_Flash_Partitions to resize the partition to fill your SD card.

Re: Getting VNC autoboot to start with "berry" screen

This is one way to start vncserver at boot time, this starts it as pi so you get the "berry".

Re: Poor analog audio from 3.5mm Jack in raspbmc

I've done some quick tests on the analogue audio quality. I used audacity to generate a sine wave sweep from 20Hz to 20kHz and saved that as a .wav to play on the Pi. I then played one channel through my Hifi and ran the other channel to an oscilloscope. The signal looks and sounds clean up to about...

Re: Cant install telnetd

You could try creating a blank inetd.conf before attempting to install it. That might allow you to install it, it's presumably trying to modify the file to enable telnet access. I've got no idea if it will work once installed though.

I've never used Arch, but I think you should have a file called /etc/rc.local this can be used to add any commands or scripts you want to run at boot time. If you edit the file and add this to the end it should start the vncserver, I've tried it in Debian and it works anyway. If rc.local has a line ...

Re: Failure to reach Login prompt

That error is probably related to the SD card, see if yours is in the Problem cards list here http://elinux.org/RPi_VerifiedPeripherals#SD_cards or search the forum for "Timeout waiting for hardware interrupt" that will give you some more info, I don't know if there's solution though.

Re: X windows session over ssh on Mac/Linux

Just tried this and it works on a fresh install of Debian squeeze 19-04-2012. On the local machine I had to do "xhost +" to allow the pi to connect to the x server, may or may not be needed depending on how X is set up on the local machine.

Re: Pi in BBC Micro case

Yeah that's the one, from what I can see the keyboard matrix is the same, just different connectors so it should just be a case of working out what goes where, probably involve a bit of trial and error, but hopefully I can figure it out.

Re: Only shipping to commercial customers in certain countries

In the UK to order from RS you just pretend you're a trade customer, make up a company name, fill in the relevant boxes and that's it, they don't know you're not a business and don't care in any case.

Can't you do the same when ordering from abroad?

Re: Official image and QEMU?

It gets the time using NTP, so as long as it has an interent connection or access to an NTP time server on it's local network it can set the right time. The real Pi will be able to do the same thing.

Cool, here's mine. I'll probably build a smaller, neater version once it's been tested with a Pi. It doesn't seem to actually need the heat sink but I had it lying around so I chucked it on there.
