- Being a Dad
- Being a Geek
- Doing exercise (cycling, running, swimming and general physical jerks).
I created a LAMP webserver on my RasPi (using this guide) and proceeded to muck about with various bits of HTML (basic made up pages), PHP, CSS and Javascript. This enabled me to create a simple home intranet that cycled through various pages of "interesting" information:
...but what I really wanted was some new and interesting data to process and present on my intranet.
For a recent major birthday I got a present that's useful for my third hobby. It's a Garmin Forerunner 910XT, a GPS multi-sports watch allowing me to log and track runs, bike rides and swims. In it's own right it's a cool gadget for a geek; for example allowing you to track open water swims by logging GPS points as and when your wrist pops put the water. Here's one I did earlier that was an accurate record of a short lake swim I did:
I upload all my exercise logs to Strava and whilst browsing around the site I came across details of the Strava API. This enables you to build your own custom web pages and applications based upon exercise data you have logged on Strava. First you need to go to the Strava developer site to log your application and get an API key. Then you can call the API using URLs like this (which just lists all activities):
https://www.strava.com/api/v3/activities?access_token=<your token here>&per_page=200
This yields a JSON response which you can parse; for example picking out particular activities and looking at them in detail:
So:
https://www.strava.com/api/v3/activities/188107339?access_token=<your token here>&per_page=200
...gives:
{"id":188107339,"resource_state":3,"external_id":"activity_579805014.tcx","upload_id":208194475,"athlete":{"id":43095234,"resource_state":1},"name":"Dutch Lake Swim","distance":195.3,"moving_time":59,"elapsed_time":484,"total_elevation_gain":0.0,"type":"Swim","start_date":"2014-08-22T15:51:31Z","start_date_local":"2014-08-22T08:51:31Z","timezone":"(GMT-08:00) America/Vancouver","start_latlng":[51.65,-120.06],"end_latlng":[51.65,-120.06],"location_city":null,"location_state":"British Columbia","location_country":"Canada","start_latitude":51.65,"start_longitude":-120.06,"achievement_count":0,"kudos_count":0,"comment_count":0,"athlete_count":1,"photo_count":0,"map":{"id":"a188102339","polyline":"ofgzH|jx{U@wBKCYtBf@F","resource_state":3,"summary_polyline":"ofgzH|jx{UI{BL|B"},"trainer":false,"commute":false,"manual":false,"private":false,"flagged":false,"gear_id":"g397875","average_speed":3.31,"max_speed":0.6,"truncated":null,"has_kudoed":false,"description":"Garmin Accurate on Course and Distance","calories":0,"segment_efforts":[],"gear":{"id":"g397875","primary":true,"name":"Brooks blue ones","resource_state":2,"distance":135654.0}}
So with some PHP jiggery-pokery I created this intranet page to summarise my Strava activities in a new and interesting way:
All the PHP and HTML is listed below. Note I'm a novice in this area so 0 marks for style I know...
