Re: RPI for professional use

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...

Re: no access to motion server

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...

Re: 40 LCDs and Raspberry pi

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.

Some of these can be useful debugging variables. %D Number of Pixel detected as motion %i,%J width, height of rectangle containing motion ...

Re: webcam on rpi

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.
