Today’s summary plot shows we have been successful getting data from the mountain over a period of two years. This is the simple on-board temperature but it shows that the network is ready for deployments with more real-world sensors!
This plot of the state-of-charge for the Lochan node shows that the charging is working very well – with a high average. It will be interesting to see the onset of autumn later.
in summer 2017 we imaged several areas to produce Digital Elevation Models (DEM) to investigate their use in repeat surveys. The 3D Robotics Solo was equiped with a Mapir camera:

On the mountain we could run Ed’s new code to sniff the 6LowPAN radio traffic and plot it – this gave us a much easier way to see what had linked up:
We managed to update the processors so we have more RAM/Flash while keeping the same sensors deployed in 2015. Sebastian’s solar powered lithium battery packs were installed in many nodes too!
The team have been very busy making new PCBs for the final deployment in two weeks! The MS2 boards were even helped along by ECS’s new pick-and-place machine – but incredibly the Munjtac processor boards were all hand-built!
in 2016 we are testing small solar panels to charge the batteries until the snow covers them. I have just sealed them using a silicone rubber:
they also get a good MIL-spec-connector and new cable.
Our “muntjac” processor/radio board is now being tested on the original ms1 interface board. It uses a CC2538 and CC1200 as its radio and has flash storage for readings. Here you can see it sitting on top of the board – which is possible as it has the same connections as the z1.
The Muntjac is very much a shortcut for us to use an ARM core – we don’t actually use the 2.4GHz radio for example.
