Re: solder a LAN socket to model a pi

That would depend on if the model A has a networking chip. You cant just attach a port and expect it to work.

Re: NAS drive

Are you trying to write things as a normal user or as root? It sounds like it wants root permission when you initiate the file transfer.

Re: Changing resolution

1. Open the /boot/config.txt and find the lines "framebuffer_width" and "framebuffer_height". Set them to your resolution. If you are using a monitor, then no overscan should be necessary, otherwise you may need to adjust it and restart a few times. 2. Yes, you can expect to have to remake the SD ca...

Re: School robot team help

Limiting costs means losing features. Break down all the components of your current idea, and see what you need vs what you want. Obviously you need a stuffed bear and a Pi, but the wireless communication and recording things isn't an absolute necessity. Im not sure how appropriate this would be for...

Re: Newbie Crashes System on Second Try

Yeah, the only reason the system would shut down completely like that is because of a lack of power. I read a thread a while ago about someone plugging in a USB keyboard and this happened, and it boiled down to the keyboard trying to charge its capacitors which drew too much causing the Pi to quit. ...

Re: Adding extra Ethernet Port.

You will need a USB to ethernet converter or two. There is no PCi slot on the Raspi. Might be easier just to connect to a 2 port hub. edit: Something like this http://www.amazon.co.uk/Tenda-S105-5-Port-Mini-Switch/dp/B0029M7TJC/ref=sr_1_8?ie=UTF8&qid=1385025856&sr=8-8&keywords=4+port+ethernet+hub o...

Repurposing a computer powersuply?

I recently pulled out the power supply from an old Dell Optiplex 260. It is a 160W PSU, and I was wondering if it would be suitable/safe to repurpose to power a Raspberry, and eventually a screen. I know a PSU has red and yellow wires, with red being the 5V lines and yellow being the 12V lines. Woul...

Re: Cannot use full capacity on SD card

Linux uses ext4 file format, which windows can not read. You may have formatted it with FAT, but that was hanged once you put the image on there. The only remaining FAT partition is that 60MB boot partition which the Pi reads to start up.

I need to run a script at 6am, and I figured I could use the at command, as I want to avoid cron at all costs. The script being run launches a browser (chromium) in full screen mode, and periodically, with the help of xdotool, is refreshed. And it does this more or less, forever. The issue I am havi...

No you don't, you just need better then the CPU on a Pi to run it. Minecraft doesn't use multiple CPUs, so more then 1 would be a waste for it.
