The Projector

TL;DR Open https://pexmor.github.io/projector/ and scan the QR with your phone.

The code is located in docs folder here in this repo.

It uses broker.emqx.io provided for free but without any guaranties, thus you might need to setup own server (either with <www.emqx.io> or as sketched in mosquitto). To override the default MQTT broker config add #mqttCfgUrl=config.json which points to the alternative config see example in docs/config_example.json.

This project was create in order to make a proof of concept that can demonstrate modern web technologies.

The keywords or technologies include, but are not limited to:

• MQTT over websocket
• MQTT server
• QR 2-D barcodes codes

Inspired by:

• Digital Living Network Alliance (DLNA)
• UPnP aka mHTTP
• Bonjour aka mDNS
• WebRTC
• Websockets

Development

Start local web server (in docs folder):

# start server at http://localhost:8088 (with CORS)
python -mpysrv

and the open http://localhost:8088

Editor

A simple object position editor concept is included in the project.

Reachable as:

• https://pexmor.github.io/projector/editor/ from Github pages
• http://localhost:8099/ from local web server which also includes the data_point server for saving and serving the elAttrs
• to run local server: python -mpysrv.dp
