I took some pictures for you guys to see: http://i1135.photobucket.com/albums/m638/BazsoDombiAndras/Components/TempSensor_Front_01_zps1a1eef67.jpg http://i1135.photobucket.com/albums/m638/BazsoDombiAndras/Components/TempSensor_Back_01_zpse9ceaa8c.jpg While processing the images, I noticed that on t...
Just to show what I was saying, attached is the port forwarding section of my router Have you given your RPi a fixed IP address and used that in the router? You can't rely on DHCP always handing out the same address when the lease expires. Have you used dyndns or no-ip or http://freedns.org to give...
I don't expose my RPi to the public internet (because my Ubuntu server is doing that and I can use it as a gateway to my RPi). On Ubuntu I got UFW installed as part of the basic software. It's definitely the easiest way to fiddle with the kernel ip tables. sudo apt-get update sudo-apt-get install uf...
Are you using a wired connection (eth0) or a USB WiFi dongle (wlan0)? If using a WiFi dongle try pulling it out of the USB socket and re-inserting it (my Edimax dongle winks a blue LED when it's working). Have you configured your WiFi SSID and password? If using a wired connection do you get the gre...
If a file is in the wrong place it's probably better to create a symbolic link to the original rather than copying. That way when you install a package that replaces the original file then the alternative destination gets the new copy rather than the stale copy. Read the syntax and options with a `m...
The choice of language depends on a number of criteria. Speed Ease of programming Ease of maintenance Processor and operating system Interpreted or compiled or compiled to interpreted byte code Procedural or object oriented For speed of running but slow development I'd choose assembler every time (I...
I was looking for some docs on the Python programming language (for a friend with a RPi, yesterday). Hopefully these two should be a good starting point for the BSA merit badge. This is the University of Cambridge education material http://downloads.raspberrypi.org/Raspberry_Pi_Education_Manual.pdf ...
I think your SD Card is less than healthy. It's not broken because you can reboot. Have you updated your RPi to the latest kernel image? What does `uname -a` show? root@pi ~ # uname -a Linux pi 3.6.11+ #538 PREEMPT Fri Aug 30 20:42:08 BST 2013 armv6l GNU/Linux root@pi ~ # If you're on an earlier ker...
Device (179,2) is the second partition /dev/mmcblk0p2 on your SD Card. The kernel is looking for a root filesystem on that partition (because that's what you've got in /boot/cmdline.txt). This is what I've got on my Raspbian SD Card dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ex...
The dns-nameservers statement relates to the iface stanza that comes before it. That means you can have different specifications depending on which interface is connected.
Download this ZIP and extract it on your Windows machine http://downloads.raspberrypi.org/NOOBS_latest Download this SD formatting tool https://www.sdcard.org/downloads/formatter_4/eula_windows/SDFormatterv4.zip Unzip that file and install the program on Windows Watch this video (seven minutes long)...
If you don't shutdown normally then you could corrupt the filesystem. To fix it you need to use `fsck` for ext4 on a Linux system. I'm surprised that XBMC isn't configured to do that automatically. If there isn't a forced fsck defined in /etc/fstab then you'll need to boot your RPi from another SD c...
You can't just use nano (or vi) on /etc/resolv.conf. That will be overwritten every time you disconnect, reconnect, shutdown or reboot. Resolv.conf is updated by the ifup/ifdown process based on what's in your /etc/network/interfaces definitions. Edit /etc/network/interfaces and add your preferred n...
The yellow socket on the RPi is composite video (in my case it's a PAL signal). Use a lead with two RCA plugs to hook it up to the composite input on your monitor. You may need to update /boot/config.txt framebuffer_width=www framebuffer_height=hhh to set the width and height to get the picture to f...
Hai everyone, maybe its a hardware issue but my laptop wont write to the sd card,using open suse 12,1 dd command dd bs=1M if=/home/harrydevries/Downloads/NOOBS_v1_2_1 of=/dev/sdb1 what did i forget? appreciate your tips and tricks kind regard Harry.. You don't want to write NOOBS to partition 1 (/d...
I want my RPi to have a fixed IP address and my home network is 10.1.1.0/24 (netmask 255.255.255.0). Your network is probably 192.168.0.1/24 (so you'll need to change things as appropriate). I set it up like this: /etc/network/interfaces auto lo auto wlan0 iface lo inet loopback iface eth0 inet dhcp...
Update your program running raspistill to have the -exif flag. Install ImageMagick with sudo apt-get install imagemagick Try this shell script: #!/bin/bash for file in *.jpg ; do convert "$file" -font arial.ttf \ -pointsize 72 -fill white -annotate +100+100 \ %[exif:DateTimeOriginal] "new-${file}" d...
does the motor control relay board have addressing to be able to differentiate between each other if a number are installed in series at the same time on a backplane? If you use a board with a MCP23017 it's addressed using I2C and you can daisy chain up to eight of them. That would give 128 uniquel...
I think this is a very bad idea. My webserver and sshd gets requests from all over the world that are constantly trying to breach my security. So I'm doing lots of stuff to prevent PHP from accessing anything important or anything that isn't transient or carefully contained in a MySQL database. I'm ...
I'm a brand new user. I have a Pi with Raspbian and I installed an RPi edimax EW-7811 wifi dongle. I ran the wifi config program. The pi sees the network, but I can't connect to it. What am I doing wrong? I'll assume that you can access your WiFi network from a smartphone, Windows laptop or Mac and...
