I used one to build a photobooth for my wedding. The raspberry pi controls a DSLR camera to take 4 photos, stitches them into a 4x6, prints the photo and uploads everything to a Google Photos album which was displayed live on a projector.

Very cool. What were you using for your Google Photos uploader on Linux?

The photobooth application was written in Python and I was able to get picasawebsync (https://github.com/leocrawford/picasawebsync) working. Even though the documentation says it's probably no longer working, I can verify that it was working for me as of September 2016 which is after the Picasa deprecation. I had to edit the source a little so that I could call it from my app instead of the command line.

Another challenge was that I couldn't find a good application to display the Google photos album. Nothing I found would display any new photos added to the album after the slideshow had begun while also displaying everything in a continuous loop. I ended up writing a second small Python app also using picasawebsync to periodically sync the photos to a second Raspberry Pi which was hooked up to a projector and display them looped in a random order.

We've built a whole business on top of the Raspberry Pi. The company/project is called Screenly[1], which is a digital signage solution for the Raspberry Pi and we have over 10,000 devices running it. We really gained a lot of momentum early on with our open source version[2].

Although not strictly a Raspberry Pi project, I have a couple C.H.I.P. boards[1] scattered throughout my apartment collecting temperature and humidity readings (using a HIH8120 sensor[2]) and feeding it to my Raspberry Pi which runs InfluxDB and Chronograf[3] to store and display a simple dashboard. The end result looks like this: http://i.imgur.com/cIrhSUq.png [1]: https://getchip.com/ [2]: https://sensing.honeywell…

Interesting... But what do you do with this data?

This is really cool! I've been thinking about a similar idea lately and this seems like a great way of doing it. Do you by chance have any material on how you got the honeywell sensor working with the C.H.I.P. board? (This would be my first electronics project)

I'm the co-founder of https://snips.ai , we are building a 100% on-device Voice AI platform to respect people privacy! We would love to see what you can do with what we are building and to feature you on our website !

I have been searching for something like this and this looks amazing! Looking forward to trying this out.

As others said, I'd feel more comfortable with an open codebase.

Built a working prototype of a LAN based discovery and routing device for Evercam.io. Not very sophisticated but it worked and it was deployed to several locations successfully in a pilot program, allowing them to route to Cameras that were otherwise inaccessible.

Actual code didn't rely on rPi (Elixir/OTP on Linux). But we shipped them on Pis. Other options considered had been Galileo and also an SoC called (I think) Quark (also from Intel).
