WiFi-enabled Banjo

Toby bought a banjo and it has suffered feature creep. We are adding a WiFi hotspot and a website.

Client Net Mode

• banjo NodeMCU operates as WiFi client
• NodeJS server to accept (preferably persistent) connection from banjo - WebSockets?
• we want snappy control of banjo from a globally available website - URL available as QRcode or tinyurl from handy page
• website shows if banjo is online or not - might provide location map too
• many people can connect to the website as visitors and authenticate in some manner (Facebook Auth is easy-ish)
• Performer asks crowd to do something on the website to authenticate - shares a time limited secret
• queue of visitors who want to control something on the banjo
• Performer has administrative interface and can see who wants to do what
• authenticated visitors can leave a message on the chat window
• banjo can indicate how many visitors there are
• this admin interface can be all sorts of things but a nice tablet might be best
