I am currently downloading a web application onto a Rasperry Pi in the hope that it will work. The idea is to use dropbox to sync a web directory when the device loads up which will then be accessed by a touchscreen interface. All files are held and referenced locally so if the internet goes down there is no downtime for people in the gallery.
The system is up and running already on a Mini-mac, and working well. Our problem is that only one Mini-mac in the gallery has an operating system that can run a modern browser such as chrome, which is needed to run the gallery app.
If and once the app works – the test will be one of perfomance and whether any css effects run too slow to make this a feasable replacement for the Mini-macs.*
Watch this space….
