Fails to take all 4 pictures on raspberry pi linux (raspbian/debian)

Hey @danrue, what is the result of running:

$ gphoto2 --capture-image-and-download

repeatedly from the command line with your camera plugged in? Can you reliably get the camera to take photos?

[danrue]

Hi @andrewhao - I'll try to do that this weekend. I'll have to re-image my pi to get it set up again.

You may be interested in an article I wrote about my experience with shmile at http://therub.org/2014/10/29/diy-digital-photo-booth/

@danrue, what a great writeup. I'm glad it worked out for you guys!

I fully agree that reliability is a top concern. I just ran the booth at a Halloween community event last night and it still crashes once or twice a night.

I will caution against rebooting the app in a while true; do; .. loop -- you need to pick the right time to reboot the server and the client simultaneously.

Anything by way of documentation or help that I could make more clear?

@danrue, @andrewhao
I've recently had a play with the porkbuns/shmile photobooth app.
I noticed the issue that you talk about here and had a bit of a play and managed to get it working in a more stable manner on my raspberry pi.

The issue is in gphoto2. In the version that downloads automatically via apt-get install there is an error which causes gphoto2 not to work with the raspberry pi and take the photos.

I had a hunt and was able to update gphoto2 via this shell script:

https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/gphoto2-updater.sh

after updating (and with a charged battery, whoops!) shmile worked well. I still have some more extended testing to do with iPad / WiFi and using and iPad's adhoc portable hotspot, but it looks good for it too work on a Raspberry Pi. I also plan to give it a try with the latest Raspberry Pi 2 with the hope that it will run a little smoother on the iPad screen etc. I think it'll work great for a Wedding photobooth!

Fantastic, @techyteach-s. Would you be willing to create a wiki page for us documenting how to set this up on Raspberry Pi?

[techyteach-s]

Absolutely, I've never made one, and I'm sure there is still some more
things to iron out, but as I have time I'll do a write up and edit it as I
find issues or enhancements.

I have written a step by step wiki on how to setup the photobooth on the raspberry pi. It's in the wiki pages for shmile. I still need to figure out an auto boot to the app/auto restart if it crashes, but it seems to be working quite well from my tests. Let me know what you think @andrewhao, hopefully some people will get some joy out of using it this way!

[danrue]

Found your write-up at https://github.com/porkbuns/shmile/wiki/Shmile-on-the-Raspberry-Pi. I will give it a shot in a few weeks when I have to do my next photo booth. Hopefully I'll have my Pi 2 by then. Thanks for contributing!

I'm going to go ahead and close this issue out.

Hey,

i've been searching since january for a possible photobooth solution for my wedding this august. Now I followed @techyteach-s instructions on github and installed shimle on my raspberry pi model B+, my setup: Canon 1000D, gphoto2 2.5.8, npm 2.13.1, node v0.12.6

Unfortunately, I still getting an error and hope that you can help me.

If you click Start on the frontend ui the countdown begins, shmile takes a photo and download it to the correct path. After this no further action continues, except of sending heartbeats, the server gives me the following messages:

....

If I run the gulp test, i am getting the error that mocha cant get an instance of ImageCompositor. Imagemagick is installed.

Does somebody have any ideas, pls?

Thx

@stowel: do you have another camera you can use to try out a different approach?

Additionally, can you try running this on a different system (one other than a Raspberry)?

[techyteach-s]

@stowel: It's been a while since I've been on, as I'm about to use the photobooth at a friends wedding I thought I'd have a look at whats going on here again. One issue I had when I first got it going was that when the camera was set to raw images it would not take the photo's properly, also, I found an error in code when using it on the raspberry pi, a solution is posted here: #33

@stowel: here's a link to the edited file that should sort out the issue, simply download and swap for the original in the 'lib' folder of shmile
