Errors

If you get a Error: listen EADDRINUSE :::80 when trying to start node laps.js it means you already have a web server using port 80. Will make this a command line option to set different port at some point. Note port 80 is the default port for web servers.

Config Options

---

transponders.json:

• by default it is filled with all transponder IDs included with the RC HourGlass project

• edit the name field to have a name show up and not just the ID

• I may add a way to edit this in the web app

• This is not required for laps to work

Project status

---

Right now this is a "personal" type lap software. You can not see everybody elses laps times at the same you you are looking at yours. I dunno if it will ever be a full race type program.

It may look ugly to you and I don't care. It works for what I want. The css, html files are changeable.

I removed the limit of one connection per transponder page.
