Yes, I agree with Panji......make sure you have notes of where you put them and remember that photos of trees without leaves look completely different 6 months later......not that I would ever make that mistake.........well not again......especially after spending 2 days trying to find 3 ARU's.

We suggest and use Python Locks for urban areas here in Australia. Can also screw the Mini 2 to a tree or phone post with the python lock.

We've deployed passive acoustic monitors in various urban environments without any issues of theft, even in locations where camera traps and other technology has been historically taken or vandalised. I think acoustic sensors generally look less valuable than other technology, and I would recommend removing or covering any stickers or labels on devices that would otherwise make them more appealing! Placing them in hedgerows or on trees with some (but not too much!) foliage will help keep them well hidden too.

Welcome, Have you considered participating in any of the AI for Good challenges. I find it is good way to build a nice portfolio of work. Also contributing to existing open source ML projects such as megadetector or to upstream libraries such as PyTorch is good way to getting hired.

We could always use more contributors in open source projects. In most open source companies Red Hat, Anaconda, Red Hat and Mozilla, people often ended up getting hired largely due to their contributions on open source projects. These contributions were both technical such as writing computer code and non-technical such as writing documentation and translating tools in their local language.

Hi Tim, I just discovered your great little device and about to use it for the first time this weekend. Would love to be directly in touch since we are testing it out as an option to recommend to our clients :) Love that it includes Australian birds! Cheers Debbie

Hi @timbirdweather I've now got them up and running and winding how I can provide feedback on species ID to improve the accuracy over time. It would be really powerful to have a confirmation capability when looking at the soundscape options to confirm which of the potential species it actually is or confirm it is neither to help develop the algorithms.

Also, is it possible to connect the PUC to a mobile hotspot to gather data for device that isn't close to wifi? And have it so that it can detect either wifi or hotspot when in range? Thanks!

Thanks for sharing Kim.

We're using <1 mA while processing, equating to ~9 Ah running for a year. The battery is a Tadiran TL-5920 C 3.6V Lithium, providing 8.6 Ah, plus we will a small (optional) solar panel. We also plan to implement a threshold system, in which the system is asleep until noise level crosses a certain threshold and wakes up.

The low-power MCU we are using is https://ambiq.com/apollo4/ which has a built-in low power listening capability.

<1 mA certainly sounds like a breakthrough for this kind of device. I hope you are able to report back  with some real world performance information about your project @jcturn3 . Sounds very promising. Will the device run directly off the optional solar cell or will you include a capacitor since you cannot recharge the lithium thionyl chloride cell. I had trouble obtaining the Tadarian TL-5920 cells in Australia (they would send me old SL-2770s though) so I took a gamble on a couple of brands of Chinese cells (EVE and FANSO) which seemed to perform the same job without a hitch. Maybe in the USA you can get Israeli cells more easily than Chinese ones? 

Message me if you think some feeding sounds, snoring, grooming and heart sounds of koalas would be any use for your model training.

Really interesting project. Interesting chip set you found. With up to around 2mb sram that’s quite a high memory for a  ultra low power soc I think.

It might also be interesting while doing your research thinking about if there are any other requirements people could have for such a platform with a view towards more mass usage later. Thanks for sharing.

I am sure Simon can chime in with exact specifications. I do not have it with me now. The centre distance between the attachment holes at each in end is 20mm wich will fit the standard holes in a collar from Vectronics Aerospace. 



Simon posted images of the logger attached to a collar on a spotted Hyeana here: https://twitter.com/chamaillejammes/status/1441657479612542990

We are studying muskoxen which are exposed to a polar night of between 3-4 month where the sun does not come over the horizon. On the other hand it also means that it will be continously OVER the horizon during the 3-4 summer months.

We are keeping an eye out for kinetic energy harvesting and there has been some interesting progress recently:

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0285930

@M_Stanton , you provide a nice list of uses of animal borne audio. We could add environmental sounds both abiotic and biotic.

We would LOVE to use audio more for ground truthing behavioural states and we would LOVE if the audio recordings could be GPS time synced...

@jared , it sounds interesting with the mentioned increased capabilities of the Iridium system. Can you link to any references for that?

Cheers, 

Lars

ISPA: A New System for Transcribing Animal Sounds

Alex Rood

8 February 2024 7:17pm

These researchers are introduce the ISPA (Inter-Species Phonetic Alphabet) as a new way to precisely interpret and transcribe animal sounds. By using text to represent sounds, existing human language machine learning models could be used more successfully in field research.
