Terra Tuesday: Collecting data from butterfly tags!

Quick Facts

It's Casey again, with another Terra Tuesday update. Yes, I know its Wednesday, but I wanted to wait another day so I could show you something cool. We have successfully collected 1 million pings from various Blu Morpho tags (the ones that are used on Monarch Butterfies) over the past 13 days! 

But sadly, there are no actual butterflies. Just lots of test Blu Morpho tags either being tested by engineers, or waiting to be delivered to many different customers around the world.  

The above test is the equivalent of 2,000 Terras receiving 500 tag beeps each in that 2 week period, which would be considered an extreme amount of activity. 

To those keen observers seeing the day and night pattern: the tag requires sunlight to operate, we don't see (many) at night. There are some since there are a few under artificial lighting. 

The above is our current database size in item count (the number of tags collected), the actual size, and the item size (the size of each record). We collect various meta data from the tag, such as signal strength, exact time of reception, and what Terra it is associated to, etc.

Our DynamoDB didn't break a sweat and even kept within AWS's "free tier"! While eventually we will have to pay cloud costs to support Terra, it is nice to see our tests incurred $0.

We will be using this same type of database for our 434MHz Motus receiver, as well as other aspects of Terra. 

Talk to you next week!

Terra Tuesday: Windscreens ahoy!

We've been working on getting together all the parts and accessories for shipping, and it's all coming together. Two big rolls of material are going to a sewing contractor to make 4000 windscreens (!) that will go into each end of the devices. We also are expecting a small but very heavy shipment of magnets, which will connect the Terra to it's support without compromising the integrity of the housing. Last but not least, the final enclosures are being worked up, and we can't wait to put it all together!

Terra Tuesday: Motus tags to the cloud!

Casey again with Tuesday's update! We are a bit delayed getting this out due to a Kickstarter technical issue regarding update posting. Above is the 434MHz helix antenna that we are using to receive Motus tags on the Terra. This is the standard antenna that will ship which each unit, unless you requested one with an external antenna. This antenna, while looking small, is actually quite powerful. Our range tests show a 500 meter radius within a neighborhood with some trees and houses. This means that Terra can pick up tags from all of your neighbor's bird feeders, including your own, depending on your specific environment!  As a stress test, we are running this receiver at CTT headquarters.
