If you don't know what a Raspberry Pi is (an ARM/Linux computer for $25), visit this link for an intro.
Here it is, ready to be connected-up to my TV, ethernet hub, and USB mouse/keyboard (shown beside a $10 bill to show the scale!):
...and here's how you connect it up (image courtesy of RaspberryPi.org):
When you power it on, you get the unix (linux) command-prompt:
The whole point of the Raspberry Pi is to provide a sensible "bare-bones" platform for teaching kids how to write software, uncluttered by all the fancy stuff that comes pre-packaged with a modern consumer-oriented device such as a Windows or Mac desktop, Android tablet/phone, iPad/iPhone or other such tablet/smartphone.
In terms of programming languages, the Raspberry Pi comes with Python pre-installed, so this is the natural starting point for code-development. However, I will leave that for another day. Instead, for now I'll simply fire-up the Chromium web-browser to test out the iNavCalc web-app interface. Note: Chromium (basically a flavour of Google Chrome which is suitable for the Raspberry Pi) doesn't come pre-installed out-of-the-box on the Raspberry Pi, but it is easy to install. I first tried the Midori browser which does come pre-installed, but the GoogleMaps (used by iNavCalc) didn't seem to load correctly...
Here, then, is the iNavCalc web-app successfully rendered on Chromium on the Raspberry Pi showing a simple straight-line sample route from EGNS (Isle of Man) to EGPF (Glasgow):
...and here is the corresponding "Get detailed PLOG" pop-up...
...and here is the response email (via Gmail, also rendered in Chromium on the Raspberry Pi)...
...demonstrating the full functionality of the iNavCalc web-app, just like on a Windows PC or iPad, etc.
Of course, this only demonstrates that the Raspberry Pi browser works as desired when rendering the FlyLogical website. But it's a start: and it gives me yet another device to use for flight-planning when all the "real" computers in the house are taken-up (for games and shopping, etc.)
On a more serious note: since I've written the iNavCalc software suite to make extensive use of web-services from the ground-up, it represents a fun and feasible challenge to build a client app (e.g., using Python) to "consume" these web-services on the Raspberry Pi. I'll leave that for another day...and hopefully convince my 11 year-old to help me.
