If you were at Snap!Con21 (or watched the recordings afterwards) you might have noticed my Mayflower MAS400 tracking project
Since then, I've been working on it quite a lot to improve the UI and I'm quite pleased at how its gone 
ProjectName=Mayflower_MAS400_SnapCon21
Requires JS enabling
Information
Enable JS (Press red top just in case things went wrong 1st time) and then press Green flag
It takes quite a while to set itself up
At the moment, its best to leave the MQTT option on replay/status as the craft is currently being re-fitted with a new generator back in Plymouth but hopefully it'll be out and about in the next few weeks again
You can use the dropdown menus to select different looking maps - sometimes these take while to load - patience is required
You can use the pan arrows to move the map around but if your in tracking mode - the map will auto-centre again on next data update
To zoom in and out you can either use the buttons or the dropdown
The dropdowns can be a bit slow (depending upon your hardware) as they are all just coded up in Snap!
Once Snap! 7 gets released, I aim to hopefully make my custom costumes reporters into JS extensions that should run a lot faster
This is what you made custom variable watchers for!
It's one of them
?
How do you get data from the MAS400?
It is supplying data using a protocol called MQTT.
It sends the data over a satellite radio link.
The concept behind MQTT is that you have a program running on a central server somewhere (which is called a broker) and a program running on what's called a client (such as the Mayflower) sending (what is called publishing) messages to it that get stored on the broker.
So its like a simple database in that respect
The clever bit is that a another program (such as my Snap! program) can ask to be updated anytime a new message is received by the broker. This is called subscribing.
Normally a program would have to keep checking the central database to see if records have been updated - in this case, the broker keeps track of who is interested in what information and automatically sends any changes out
Is that allowed?
Not only is it allowed - it is encouraged by the IBM team behind it
The data is freely available to anyone who wants to use or look at it
Hopefully, later on today, the team are hoping to add the data they collected on detecting sea creatures and I'll be able to popup little graphics of whales and dolphins etc
What is an IBM team?
If I'm not mistaken, it's the people who work at IBM.
Link plz.
Wdym? A link to IBM?
No, a link to where
I don't have a link, ask cymplecy.
I can understand them.
There's no link to any licence so let's keep it our little secret for the moment
Here is link to their own dashboard and tracking (currenlty offline while repairs continue)
1st draft of showing detected boats on the replay journey
[edit - turns out most of these boat sighting were of a support vessel that was following Mayflower.
It stopped following a little further out
