Raspberry pi USB reset

[techyteach-s]

Hi Hugh,

I'm not sure if the issue you mention here is the same problem that I was having, but if you have a look in the Shmile on the Raspberry Pi Wiki I've resolved a problem I had, what would happen is that after say, 2 photos the script would fail. I managed to resolve the issue by modifying the image_compositor.coffee

From the wiki:
Issue that causes program to only take 1 or 2 Photos

I found when I initially got the Raspberry Pi running that it had issues only taking 1 photo at a time. After much frustration I found that the new version of imagemagik had a new argument, instead of -size it needed -resize. In line 61 of the code for image_compositor.coffee -size needed to be changed to -resize, once this was complete it worked without any issues. Furthermore I also found that the SLR connected needed to be setup to take photos in only JPEG, not RAW, this also causes some issues.

An edited version of image_compositor.coffee can be downloaded from: https://github.com/techyteach-s/shmile-Raspberry-Pi-fix

simply download, and substitute it for the file in the 'lib' folder of shmile.

Let me know how this goes for you.

I had the photobooth going using a raspberry pi and ipad mini for my wedding on the weekend and it worked great, only issue I can find presently is that there seems to be a memory leak and the script/pi (depending on setup) has to be restarted every 20 uses or so.

Hope this helps - Simon
