If it's just a simple vending machine, I'd say Arduino is more suitable. However, if you want to get fancy, say like pool table that accepts bitcoins, then Raspberry Pi would be great. I don't think you need to worry about SD card failures, unless it's in vibration heavy environment. Then you need t...

I had a lot of trouble running motion as a service. One bad permission, and the whole thing came tumbling down in unexpected ways. I end up running it via cron macro @reboot, instead. Much easier to do. Check that you set your ports correctly. webcam port and control port are two different ports, an...

This may not be what you want to hear but if indeed you want 40 different displays, wouldn't it be easier to just set up a Master-Slave network configuration and attach a Raspberry Pi to each displays? Even something simple like an intranet web server should work fine, and trivial to set up.

The automatic threshold_tune should work just fine. There's also noise level that you can use. If you look at the Conversion Specifier, you'll see various flags. Some of these can be useful debugging variables. %D Number of Pixel detected as motion %i,%J width, height of rectangle containing motion ...

First, learn the shell completely. I use the book The Linux Command Line by William E. Shotts, Jr, but there are other books out there available. Second, don't give up. Your current understanding may not be enough for audio streaming, but streaming server is actually one of most difficult thing to d...

Backing up is a very difficult subject. I actually spent a week learning how to do it! That said, here's what I came up with: 1. dd . Clone your SD card to another one. 2. Next time you want to back up, use rsync 3. If you want to keep running copies, use tar with -z option. Reducing SD image is to ...

I hope someone will make SmallBASIC available in RaspbianRepository, it should be trivial since the debianisation work is already done. Cheers, Chris I would like to see SmallBASIC be available in Raspbian Repository also. I've tried BBC Basic (too old), TinyBasic (too tiny), BASIC256 (Rough around...

The very definition of Hacker. I salute you. Too risky for me, though. I'll stick with Micro adapter instead, even though I have Dremel I can use for the project.

I believe this is just me, but I think an enabler device is not enough without proper instruction. So I suggest adding a few books to the package. Raspberry Pi for Beginners bookazine www.imaginebookshop.co.uk is a great introduction. If your son knows what he's doing, he may already source all that...

That's great calculations, but wouldn't it be easier to set up expandable system instead? Set up some solar charging system to battery that powers the Pi. Keep adding panels until the battery lasts all winter.

Yes you can leave off monitor and keyboard. That's how I set up mine. Note that once you install motion via apt-get, you may need to install ffmpeg and avcon as well. I also suggest that if you want to run it headless, to have the program running at boot. With USB camera, you can easily just pull th...

In the end, I "formatted" the SD card using sfdisk fed with text data. Like this: echo "# partition table of /dev/sda unit: sectors /dev/sda1 : start= 16384, size= 7684096, Id= b /dev/sda2 : start= 0, size= 0, Id= 0 /dev/sda3 : start= 0, size= 0, Id= 0 /dev/sda4 : start= 0, size= 0, Id= 0 " | sudo f...

I did use the Write option on cfdisk. That's what I don't understand. The man pages are describing the issues in general terms. Which means I can't be specific. But the question boils down to "How do I format SD card in various sizes, in various file system?" It's a common question, one that I thoug...

It's usually much better to start-small and work your way up, than to start with a "full Raspbian" and try stripping bits out. :? There should be an "official" smaller image coming soon http://www.raspberrypi.org/archives/4959#comment-255606 Usually, yes. Not in Raspberry Pi case. Most people would...

I'm having trouble using fdisk, cfdisk, and parted to format my SD card. I researched some topics in the forum, but most of the messages specifies Windows, Mac, or digital camera solution. Not at all what I'm looking for. I'm totally baffled with fdisk interface with sectors, cylinder and what not. ...

I've been using it as desktop replacement from the get-go. Midori is certainly preferable to the alternative. Mind you, this is because YouTube decided to force feed autoplay their videos. In a forum where multiple youtube videos are posted, not only it was confusing, it drained my monthly bandwidth...

Ha ha. Yeah, disabling screen saver can be a pain. That's why I added that capability on my Noob Tools script. Just do "noob noblank" to disable screen saver. "noob blank" to enable it. It only works on GUI, though. I didn't make it for terminal. Add gpicview program, and you have a full screen slid...

These are fantastic, and I'd love to have one! I'm trying to make one with wood, but I think 3D printed would be the way to go. PiBow version would be nice. I suggest that you use tall switches plugged with button caps, so that you don't have to do cut outs just to access the buttons. I think Adafru...

I have been working on a script called "noob", which is basically a collection of shell commands in one big easy-to-use script called noob . This is still work in progress, but I did manage to finish clone command. So, I figure to throw this out here, and see if there's any feedback for the work so ...

I connected mine to powered USB hub. By switching off the hub, I shut off the Pi. After I did a "sudo halt", of course.

Or you can cheat and use a wireless keyboard instead. That way, you don't have to mess around with keyboard wires at all!

changing the directory on motion should not cause a change on the web server. Was it working before you change the directory? If not, then look for webcam_localhost and control_localhost config option. If yes, then I suspect permission problem. I had to change the permission to 666 to enable read/wr...

Can you drop some names? I've been looking for one and has been unable to find an affordable one without being attached to their "easy-to-use" graphical web builder, when all I'm looking for is a simple ftp option. Also, I forget where I found it, but I believe that there is at least one company who...

Camera module $40. Cheap USB camera $10. No contest. Besides, mine works just fine.

I use "motion" software on mine. Works great. Tend to be resource hog, though, so you may not be able to multi-task with it. I have yet to try Camera Module. Lack of proper case, and an already functioning webcam puts it into low priority.
