Ecology is a strange discipline. At its most basic, it’s the study of how living things interact with their environment. It doesn’t so much seek to explain how life works, but rather how lives work together. A guiding principle of ecology is that life finds a way to exploit niches, subregions within the larger world with a particular mix of resources and challenges. It’s actually all quite fascinating.
But what does ecology have to do with Luka Mustafa’s talk at the 2018 Hackaday Belgrade Conference? Everything, as it turns out, and not just because Luka and his colleagues put IoT tools on animals and in their environments to measure and monitor them. It’s also that Luka has found a fascinating niche of his own to exploit, one on the edge of technology and ecology. As CEO of Institute IRNAS, a non-profit technology development group in Slovenia, Luka has leveraged his MEng degree, background in ham radio, and interest in LoRaWAN and other wide-area radio networks to explore ecological niches in ways that would have been unthinkable even 10 years ago, let alone in the days when animal tracking was limited by bulky radio collars.

The Broadband Internet Service BenchMARK is an open source initiative to put tools in the hands of the common Internet user that will make measurement and analyzation of home network traffic easier. It targets LAN and WAN network utilization by measuring latency, packet loss, jitter, upstream throughput, and downstream throughput. Of course gathering data isn’t worth anything unless you have a way to present it, and to that end the Project BISMark team has been developing a web interface where you can view the usage of anyone who’s running the firmware.
The project builds on top of OpenWRT, which means that you should be able to run it on any router that’s OpenWRT compatible. This includes the ubiquitous WRT54G routers and many others. We remember when DD-WRT added bandwidth monitoring as part of the standard release, which really came in handy when the stories about ISP bandwidth capping started to hit. We’re glad to see even more functionality with this package as it can be hard to really understand what is going on in your network. After the break you’ll find a video detailing the features of BISMark.

[GuySoft] threw together a cellphone-based SMS gateway that allows him to push text messages to Twitter. Once up and running, it can be used by multiple people, either with shared or individual Twitter accounts. At its core, this setup uses the cellphone as a tethered modem on a Linux box. The open source software package, Gammu SMSD, provides hardware hooks for phones running in modem mode. The package is already in the Ubuntu repositories but it runs cross-platform and can be downloaded from the project site. This gave [GuySoft] the ability to script a framework that checks for received SMS messages, compares the incoming phone number for a match on a saved list, then pushes the message from a confirmed number to Twitter via their API.
A web interface is used to register new numbers and associate them with Twitter accounts. On the back-end, [GuySoft’s] own Python script handles the translation of the message. You can download all of the code, and get more insight on setup from the readme file, over at the GitHub repository.
[Matt Richardson] built this on-air light to indicate whether a Make streaming show is currently in progress. Despite the obvious cord leaving the bottom of the base (it’s a power cord) his creation is pulling data from the Internet wirelessly. He’s using an Xbee module along with an Arduino to pull this off.
In addition to the light itself there’s a base station that we haven’t seen before. The hardware is a Digi ConnectPort Zigbee-to-Internet Gateway. That’s a mouthful but it’s just a box that acts as an Xbee node and facilitates communication between its own Ethernet port and other Xbee devices in the network. So no, you don’t need a computer but you do need an Ethernet connection somewhere for the base station. [Matt] is running an open source software package on the ConnectPort call Xbee Internet Gateway (xig). Watch the video after the break to see the configuration for this package. It’s a snap, and if you’ve never used an Xbee module before this gives you a good idea of how easy it really is.
