A client came to me and asked if it was possible to build a kiosk app that runs on screens in several stores.
What I would do is make the app that runs on a Raspberry Pi. But more like a Raspberry Zero kind of thing. It would be connected to the HDMI connector of a display. Most displays have a USB port that could provide power to the Raspberry. It would help if the Raspberry has WiFi, to update the content to be shown on the display.
I have seen some videos on making Raspberry Pi’s work as a web browser. I just want to be able to use the display whenever there is no internet connection.
Of course, a store has to be able to assign a store ID to the Raspberry. Maybe an iOS (or even a desktop) companion app could help out. I’ll figure that out as I go.
But I read (somewhere) that Xojo isn’t compatible with the Zero. Does anybody know a tiny Raspberry that is compatible with Xojo?
Why, seriously why? You are already going to be humping a lot of hardware around the place in any case, so a standard Raspberry PI is not going to make any difference. By going with the tried and tested you reduce a project risks, which helps ensure your success.
