Geospeed

An app for getting the current speed limit, wherever you are.

Overview

This is a Ruby on Rails (4.2) application with two main components:

The front-end React application. Pretty much all of that code lives in app/assets/javascripts/components. The front end app served is a basic static site with no dynamic data.
A server-side API for getting speed limit data. This is a simple wrapper around the Overpass API. Most of this code lives in app/models/overpass.rb.

Shows the road where the currently displayed speed limit is relevant to. This is useful when geolocation information is slightly inaccurate.
Show current speed and speed limit.
"HUD Mode" where text is mirrored, so you can reflect the screen off of your windshield and use the app as a HUD.
A color picker to change the color scheme.

This is a relatively straightforward Rails application to install and hack on:

git clone https://github.com/hstove/geospeed.git
cd geospeed
bundle install -j4
bundle exec bin/rake db:setup
bundle exec guard

Running guard will startup the server and setup LiveReload and guard-rspec.

You can self host this app with the click of a button:
