μMoth - oh wow, oh wow!

Amazing work! https://www.openacousticdevices.info/mmoth

Clearly it is early days, but obviously so many questions pop into mind ...

- Off board Lithium ion battery, with a onboad connecter? (So you can choose any size LiOn? or LiPo? like - https://hobbyking.com/en_us/turnigy-2000mah-1s-1c-lipoly-w-2-pin-jst-ph-connector.html ?)

- Any Battery life / runtime estimates vs AM1.1?

- Cost? Double side so more expensive?

- etc, etc, etc ... Anything else to share with us yet??

We should have the first group purchase campaign for uMoth in month or so. We’re finalising some of the assembly details as it’s a bit more involved than the standard board having components on both sides.

It runs all the same firmware as the other AudioMoth models and has the same microphone as AudioMoth 1.0.0 hardware.

The energy consumption is the same as existing AudioMoth but you can pair it with any size LiPo batteries depending on the application. A small batteries like this - https://coolcomponents.co.uk/products/lithium-ion-polymer-battery-850mah - will give about 60 hours of continuous recording at 48kHz and about the same threshold recording at 384kHz.

Hello Alex, Please could you recommend a protective casing for the micro-moths?

It really depends on the application. For short deployments, a freezer bag works well. We just use ziplock bags of the weather is good and it’s a single night. There is quite a good discussion here - https://github.com/rhine3/audiomoth-guide/blob/master/guide.md

For on animal deployments our collaborators have also used shrink wrap sleeving which makes a waterproof enclosure which the sound passes through easily. Lots of bird tags are deployed in this way.

It would be great to hear some more info about the micromoth. Where are the CAD files, what is the cost, could we transfer data through another port?

Will μMoth have acoustic trigger (for bats) capability?

Any update on a release date or specifications for the μMoth. We are keen to strap audio devices onto Koalas but we will need to know the power draw of the μMoth to determine if this is our best option. The regular audiomoth has great sensitivity for recording low (even subsonic) frequencies so we are hoping that this version will also and that it is released sooner rather than later.
