ArduPlotter – 3D Map (CesiumJS)

So on Christmas Eve I was tracking Santa (as you do), and noticed that the NORAD tracking no longer opens up Google Earth, but instead works in browser.

Doing some digging around I found that they used Cesium. This uses WebGL to create 2D maps and 3D globes. From the start of ArduPlotter there has been a button to download a (generated) KML file of the flight which will open in Google Earth if you have it installed. Being able to view a 3D map in browser seemed like an awesome idea, so I set about making a quick prototype.

Linode DDNS and OpenWrt updater

Linode DDNS updater script

So my domain registrar doesn’t do DDNS (dynamic dns), but Linode have an API to update your DNS records that you have on their name servers, so you can do DDNS with your own domains really easily!

Eclipse, PHPUnit, xdebug, MakeGood and Ubuntu (PHP Unit testing)

Well after about 2 hours of head desking I have I got the above to all work nicely together.

This will install a bunch of stuff you will need. If you want to install from source feel free.

Arduino + LCD + Telnet = good fun

So I have been playing with my arduino with a LCD I got ages ago. First off I had to solder some pin headers to the LCD so that I can plug it into a breadboard. I could have soldered the pins straight to the LCD but I used some ribbon cable in the middle, and some veroboard (Note to self: Get a dremel for birthday, that stuff is a pain to cut though!) to add flexibility and some give if/when I drop it… Continue reading
