Hello, I'm experiencing problems with external mics on a AM v1.2.0 (sw 1.6.0). They worked well a few months ago, like the SPM0204UD5 (see previous post from Edwin) and Animal sound Labs ME4-em. But now I don't get any recordings with external mic, no reaction at all. I barely used the device so wear is not the cause. Am I overlooking something or is there a possible software or hardware issue? I tried several cables, even directly, but no difference. No problems with the mics neither, they work just fine. One thing puzzles me: I used the mics with the previous sw-version when I tested them the first time, now I have 1.6.0. Could this be related? Is there anyone who is using the same mics with sw 1.6.0? Thanks for thinking with me. All the best, David.

Hello all. For those who are looking for some inspiration: I found a cheap yet practical shock-/waterproof case. Available in three colours (beige, black orange) in the Geek/Wish store. With some minor adaptations it’s ideal for the AudioMoth. The inner lining consists of foam in which the shape of the AudioMoth can be easily cut out. For the fixation of the membrane I was inspired by the Aurita design and used a PVC shoulder washer. After drilling a hole just above the mic I enlarged it until the washer fits tightly. Since the materials (plastic vs PVC) are difficult to glue I used butyl tape to attach the shoulder washer. The membrane, standard cling film (10 micron), is mounted on top of the washer. In order to prevent damage by the sharp edges there there is an O-ring on top. The second O-ring stretches the membrane over the first one and provides extra protection against water ingress. I also provide a silicagel packet to prevent condensation on the membrane and as extra safety in case of the membrane is compromised. It is advised to check the membrane after each battery change because the cling film degrades due to weather conditions. Also the O-rings suffer from UV-degradation after a time so be sure to check their condition as well. The box has two ‘eyelets’, very convenient to attach the box. The box costs 2€ and together with the other stuff you have an excellent enclosure for less than 5€ and 15 minutes crafting.

Hello all. When I want to program the recording schedule from, let's say, 22:00 to 06:00 (see image) the Audiomoth only starts recording from 0:00h to 01:59u the same night. So just two hours. What could be the issue here? Thanks.
