running a camera and wireless station from batteries

Im thinking of setting up cameras away from my house and need advice on the power. basically they will be mounted on poles down fields from the house. what i plan on having is a network camera setup with the Ubiquiti wireless points (https://www.ubnt.com/airmax/nanostationm/). these will form a bridge of 2 or 3 cameras and the cameras will be connected to each, with one of the wireless points mounted on the top of the house to connect to.  what i cant figure out is the power. i would like to run a power cable down the field sometime but this will be costly and i want to try this out to make sure it works. i know deep cycle batteries would be best but i cant join the rest together. i know there will be a POE connecting into the wireless box and this will be split, so how would i join this to the battery, as would a converter be needed or any other suggestions would help. thanks!

Arduino over Ethernet: Microcontroller Noob

So I have an Arduino R3 with PoE and I'm trying to find a way to make it perform basic tasks by calling the tasks from a webpage. The problem is, I don't know anything about microcontrollers apart from Op-Amps and FF. Also, I can't web code. But I'm a fast learner and I hope someone can show me where to begin. Thank you.

Convert battery power to low voltage?

Is there an easy way to convert a security system sensor from battery (2 3V lithium batteries) to a wired low voltage line? I have pulled the cover off the sensor (image attached) and it doesn't look too complicated. Other options would be to convert it to POE or USB. Don't know if that's doable or practical. I'm building a house and have an opportunity to never have to replace those batteries, which are not on my "be nice to the environment" list. I have plenty of low-voltage in the house already. There is also built-in solar backup for 12-15 hours for power outages. Thanks for the help.

Pen that uses blood for its ink

This massive custom pen uses blood for ink. Stick the syringe in your arm, draw some blood, and load it up to start writing your Poe-inspired masterpiece.I've gotten much better at having blood drawn and it doesn't bother me now, but I don't know if I could take some of my own. I'd love to feel how well it writes, though.Only the first minute of this video is worth watching. The rest is just more writing.Note: This is not me and since there's no proof that's blood (watch the editing), I think this is more of a concept and is using red ink. via Core77

Spa Controller Modification utilising Microcontroller Remote Station

Hi All, I'm looking at modifying our existing Spa controls with a Touch screen system that combines the functionality of the radio remote for the Spa controller & the remote control panel for the Spa heater. I also want it to be able to run the Sonos software and possibly do lighting control down the track. I would like to leave the existing water proof remote operational if possible but that assumes I can get the new 434MHz module in the microcontroller talking to the existing Rx in the Spa Controller and dont have to replace it. Im interested in any comments particularly as which mini computer to use. Price is a concern of course by function is more important. I havent worked out how to power it yet as there is no easy solution without nearby power points or network ports for PoE. I may perhaps go solar but not sure yet. It may be easier to run a cable for somewhere. Any insights much appreciated...

Crows and Ravens in Mythology.

Crows n RavensFor centuries the corvids, ravens and crows in particular (corvus corax is the Latin name for the common raven and corvus corone for the carrion and hooded crows), have had a special place in the mythology of various cultures. In modern times this fascination has barely diminished. From Edgar Allen Poe's literary classic to the film of James O'Barr's cult graphic novel "The Crow", these birds still exert a powerful hold over the psyche of a significant fraction of the population. The Goths who paint their faces with white make-up and the weekend warriors who expect Raven to take them to the Otherworld to meet the dead do not see the same animal as the farmers who set up decoys in order to shoot large numbers of them every year in late spring. This is, however, typical of a creature that presents a paradox wherever one looks.Corvids are sociable birds. They tend to form social groups, and this can be seen particularly in the case of rooks, which stay in their flocks all year round. Ravens, the largest of the family, reaching as much as 3 feet from beak to tail, form groups as juveniles, pairing off into lifelong monogamous and extremely territorial relationships at around the age of three. The courtship can involve such fun and games as synchronised snow sliding, and, of course, the synchronised flight test. The corvids can be found all over the world, and are the largest of the passeriformae, or songbirds. The common raven is widely distributed throughout the Northern hemisphere, and the adaptability and intelligence of this family have made it extremely successful.As far as the mythology goes, the first confusion arises over the distinction between Crow and Raven, at least on the European side of the Atlantic. The two appear, in many instances, to be interchangeable, and the appearance of one or the other in a story depends as much on which author is transcribing it as it does on story itself. Whereas John Matthews 1 gives Bran the raven almost exclusively, Miranda Jane Green 2 ascribes to the God's companion animal either the crow or the raven, much as both authors do for the Morrigan. The confusion on the American side of the Atlantic is not so profound. There is a distinct geographical trend in the likelihood of Raven appearing in a story, and so we will start our examination there.
