Re: USB Hard Drive Permissions

Well, after eventually having success at formatting the HDD with my Pi, I still struggled with permissions, and couldn't save anything to the HDD. Messing around with My LinuxCNC PC (Ubuntu) I managed to open Nautilus Browser from Terminal as SUDO, which then allowed me to set permissions, and copy ...

Re: USB Hard Drive Permissions

Change of hardware seems to have helped! I was using a cheap caddy I bough from ebay, which relied on USB power. (I have a USB hub with 2A PSU, and the Pi is runnig from it's own 2A PSU) The HDD had 0.85A stated on it, this may have been the issue, the caddy may not have been able to supply the powe...

I've also tried making changes to FSTAB using leafpad and found that I can't save the changes.

I think I need to make the changes using SUDO and some terminal text editor??

Success! I've managed to format the external USB HDD to EXT4 using GParted! I used a different USB ->SATA caddy, and my problems went away. This drive's main purpose is to carry movies / music and play back with XBMC away from home. At home XBMC reads my media over the network from a NAS. However, I...

Re: LCD / LVDS Interface for Raspberry Pi

Very interesting board, well done!

I have one question; is there a cheaper alternative for non-touch LVDS screens?

I have just inherited a few old laptop screens, and quite like using a keyboard and mouse.. So touchscreen is not essential or desirable for me.. However, low budget is.

Re: Voltage free pins?

Galvanic Isolation is a broader term, also covering Opto-Isolation and Transformer Isolation.. Volt-Free Contact or Dry Contact are a little more Relay-specific. These are terms I've only recently started using myself! Check out Luigi Galvani http://en.wikipedia.org/wiki/Luigi_Galvani and the "Galvo...

Re: Voltage free pins?

I think he wants to use the GPIO of a Pi to remotely turn on his PC... ?

If that's the case, then a relay across the PS's front power button would be fine, but the code behind remotely controlling a GPIO pin would be another story! Across the internet perhaps?

Re: Voltage free pins?

I think he wants "volt-free contacts". You wont find any on the Raspberry Pi; you'll need to connect a FET, optoisolator or relay to the GPIO. Ah, that makes a lot more sense! If driving a relay, you'll probably need to use a transistor, as the Pi can only supply 16mA from it's GPIO pins, but not a...
