Re: Shutting down

I use sudo shutdown -hP now Off course on the Pi this will not remove the power but it safely shuts down the system. I have the text in a file called off in /usr/local/bin [email protected]:~$ cat /usr/local/bin/off #!/bin/bash sudo shutdown -hP now [email protected]:~$ To make the file executable you need to sud...

Can you just switch off motion detection in motion? I had a feeling you could but it's years since I've used the package.

Re: What can I do with it?

First of all type your IP address in another machines browser and see if anything happens. Probably nothing. e.g. pic-1.png If nothing then install a web-server on your Pi. From your Pi issue the commands sudo apt-get install apache2 Wait 5 minutes or so for the software to download and install and ...

Re: Dealing with the Memory Limit

Banked memory was common with early 8/16 bit processors. Not sure if there was any kernel/operating system support as such. I seem to remember ad hoc hardware/software solutions depending on the engineering needs.

Re: SD Card Partitions

When you write the image to the sd card a number of partitions will be automatically created (the image write is done at a low, also called raw, level). When Raspbian starts it will offer to resize the partitions to make full use of the sd card. This resize will be done during the next boot, which w...

Re: wireless solar nature/security camera

I'm not sure if you'll be able to power the Pi via the usb ports, the polyfuses will get in the way. You should be able to power the Pi by bunging 5V on the gpio 5V pin (gpio pin 2) and connecting 0V to GND (gpio pin 6). I'm powering my Pi with 8 NiMh cells feeding a 5V UBEC which in turn feeds the ...

Re: I have no idea what I'm doing

I wouldn't have thought the machine would have been suitable for that application. I doubt the CPU or network subsystems are fast enough.

Why not just stream from your primary PC?

Re: Firmware Update Troubles

I use rpi-update to update the firmware (I'm using Debian, I understand Raspbian updates it automagically without rpi-update now). It regularly corrupts my boot partition. I take the card out, bung it in a Linux machine, unmount it, and run sudo dosfsck -r /dev/sdb1 (or whatever device your sd card ...

Keep an eye on the leds next to the power led. The green led should flicker as you apply power (it indicates sd card access).

Re: Any 3d CAD software for Pi?

Searching through the Debian packages for 3D CAD brings up opencascade-wok. You could try

sudo apt-get install opencascade-wok

It may work but it also may well be a frustrating user experience.
