Blog post to write

[Nanoseb]

Here is a list that I'll try to update of blog post that should/could be written:

• : Sunday's lake test: new checklist, gps jumps, xsens respawn, 2d map/dashboard?
• : Battery voltage monitor
• : New helming node decision
• : Journey toward GPS with i2c (see uBlox GPS with i2c sailing-robot#230)
• : Saleae logic analyser

I've written and pushed an article about the i2c gps, can you have a look over it and see it's alright?
https://github.com/Maritime-Robotics-Student-Society/blog/blob/gh-pages/_posts/articles/2018-06-08-Journey%20to%20I2C%20gps.md
I'll add a thumbnail as well

That's really good!
Just a few notes:

• On the screenshot, maybe you can circle in red the location of the clock stretching
• About the clock stretching, mention that this randomly hang the pi (that's why we came across the article btw), and the only solution after that is to reboot
• Mention at the beginning the part number of the gps, it might be helpful for people that google it, and good to know for others anyway
• 2s gps fix is not an issue with tacking (tacking failure/success is checked with the imu/heading), it is more an issue for global path planning and to see if we passed a mark for example

And I've just fixed a couple of typos. Otherwise it is very good, thanks!.
