Hi Florian,

I hear you on the crystal problem... You can search for 49.86MHz crystals, this is a standard frequency for old time radio control models. I've seen them on taobao in HC49s, but not in a tiny 3225 package for which 50MHz is available. But if you have to use HC49s, then if... (read more)

Hi Alasdair,

Very interesting MFC, I notice you're using 4 cells apparently in series, how do you keep the current collectors (carbon cloth) from shorting?

Thanks,

Hi, you can contact Telenax, they buil GPS-IRIDIUM-BLUETOOTH+VHF units, these are simple to configure it and to use them also. you don't need to do field work, only to retrieve the unit when you use drop off or to recapture the animal using VHF.

Freaklabs posted in Security Enclosures - Your thoughts in the Camera Traps group - 23/03/2019

I think that tracking would be an interesting way to go, but the issue is that if you do discover who takes it and the person is dangerous, how can it be handled. I guess it's more of a game of deterrents and understanding why people take the cameras. If they just think they are security cameras... (read more)

Hi Harold.

Thanks for the reply. It'd mainly be for data acquisition, ie: weather as well as possible hydrophone and other sensors to measure parameters in the ocean. There's no fixed project for it yet, but wanted to know how difficult to build one. This type of thing keeps resurfacing... (read more)
