Open Source Solutions / Feed

This group is a place to share low-cost, open-source devices for conservation; describe how they are being used, including what needs they are addressing and how they fit in to the wider conservation tech market; identify the obstacles in advancing the capacity of these technologies; and to discuss the future of these solutions - particularly their sustainability and how best to collaborate moving forward.

New paper - Real-time alerts from AI-enabled camera traps using the Iridium satellite network: A case-study in Gabon, Central Africa

Sending real-time alerts from ecological sensors such as camera traps in areas with poor data connectivity is complex and involves integrating a large number of potentially complex hardware and software components. Our results demonstrate that these components can be successfully integrated to achieve reliable, near real-time alerts from camera traps under challenging field conditions.

Global shortage of Raspberry Pis - What are the alternatives

So, there is a global shortage of Raspberry Pis, the open source micro-computer that has been popular amongst open hardware designers and hobbyists alike. Like...

Hi @tom_august this is a very important topic given the global shortages we are seeing. I tend to use really low power micros rather than Pis for my stuff if I can, but I'd be very interested to hear about alternatives. I take it you are doing some reasonably heavy processing given the need for 4Bs? I have a few old 3s you are welcome to. A great list from @PshemekZ there. I don't know much about these: 

But didn't see them in the list. 

 @Freaklabs will likey have some ideas too. Looking forward to hearing more.

Cheers,

Rob

Unfortunately not much to add. I think there was an assumption that Raspberry Pi's would always be available and it's turning out that it's unfortunately not the case. I'm guilty of this for standard chips. I didn't think there'd be such a huge shortage that spread across so many chip families which left us scrambling.  I'm sure the supply crunch will ease up soon so the RasPi shortage should ease. It should be considered thought that should something happen to the Raspberry Pi Foundation, there's a possibility that the production could end. Since Raspberry Pi's are not open source, this would be devastating to many projects that rely on them. 

As for porting to another platform, I guess the question would be which platform to bet on for the Raspberry Pi alternate and possibly eventual successor. It would probably need to be open source, widely available, and have enough community around it to support itself. Nothing immediately comes to mind (Jetson possibly but not open source and subject to whims of nVidia).

And perhaps this could turn into a community project to come up with an open platform that conservation communities can standardize on where availability could also be guaranteed. There's a lot of exciting things happening with the RISC-V architecture, which could be a good candiate.

As an update from us, we are playing around with two alternatives:

  • Banana PI BPI-M5 M5 4GB 4 x 2GHz 
  • Radxa Rock 4 SE 

I'll update once we have results!

Picking up signal of GPS tag

Hi all! Has anyone been able to collect any ID information from a GPS tag, by circling above with a drone? Thinking about FAD detection at sea.Thanks!

5 0

Thanks Carly! I've been in awe of what Wildlife Drones is doing, but as you say my work at the moment is focussed on existing GPS units rather than telemetry for tracking. I'll still reach out & ask though. Thanks for your help! :)

Hi Kim! Thanks for sharing, this is really interesting! I'll check out the website & see what I can find out about the mechanics of the device. Thanks again!

Hey Sol, 

The only way for you to collect information from a GPS tag attached to a FAD is if that tag transmits that data to the drone. Unfortunately most receiver packages are a bit too large for hobbyist-style drones (from what I've seen). 

Depending on the range/distance from shore, you might be able to have a shore-based receiver system?

Software to aid acoustic sound files visualization/labelling + Software to syncronize video/acoustic sonograms

Hi everybody!I am currently trying to figure out if there is any open-source software that could improve our citizen science project on bat monitoring in Europe (and potentially...

I would also recommend Arbimon. It is well set up to handle Audiomoth recordings. Being cloud based, you will need a good internet connection for sound file upload. I'm just starting to investigate its use for Song Scope recordings. Setting up the call recognisers will be a slow process, but they can be made available to all users once done.

You could try using a video editor like DaVinci for looking at your video and audio together. I don't think DaVinci displays sonograms by default (just waveform) but I think it will open your selected audio in an external editor which would allow you to see the sonograms and make measurements with something like Audacity or Kaleidoscope.

The open-source program Audacity can show the spectrograms and histograms and has quite a lot of other useful features, e.g. playing ultrasound calls slower, so it can be heard by people.

How can open source tools make conservation tech more sustainable and accessible?

Open source tools help our community think of creative solutions, share resources, and make conservation tech tools more affordable and accessible for everyone. All of that...

1 1

I've been working with a current visiting scholar who's from China and has been interested in getting started with some acoustic monitoring studies when he goes back to China later this year. I've been working with him to try to figure out some options (with some help from folks met through Wildlabs!) but the name-brand stuff from Wildlife Acoustics is more than double what it would be in the states once customs and imports and exchange rates are taken into account. Open-source solutions that can be manufactured on the ground in countries where we're trying to do work can avoid many of those costs, support local economies, and even be good for the environment to the extent that you're avoiding the (minimal but non-zero) emissions of shipping stuff all over the place.

Hello Aadithya,

Excited to hear about your marine acoustics outreach. I am interested to explore the possibilities of collaborative work on this line.

One of my doctoral scholars is about to submit his thesis on terrestrial acoustic studies. Please respond to [email protected] (as I may likely miss responses if any, send to this group). 

Regards

Jaishanker

Hi Jaishanker, I just reached out to over email, apologies for the delay. We are interested in working with underwater hydrophones and this might be of use in your specific case study. Bristlemouth's timeline is still being created, but we're hoping to have devkits ready closer to the end of this year. I'm happy to chat more to learn about the specific research you are doing and how we can best help!

If you're looking to identify collaborators - probably lots of organizations listed in the Conservation Tech Directory would be interested (quick prelim search yields orgs like Echospace, European Tracking Network, FACT network, IMOS, IOOS, other tracking networks like that, USA's NEON, eOceans, Oceans+)! Also org's like Blue Ventures, Save our Seas (run acoustic tracking array), MBON (run Biotrack) come to mind.
