Hello everyone!
For the start i want to say I had to do with Time Lapse before - it was part of my normal video projects. Im thinking about getting something "little bit longer" than couple of hours - 6 months to be exact
Sadly i won't be able to check on the camera more often than once every two weeks so I've started to think over a solution to make it care about it self as far as possible. At this point:
- DIY hermetic housing for the camera and other stuff;
- 3G/LTE router with WiFi;
- Eye-Fi Pro SD card to send RAWs on to the server;
- Intervałometer (build in or a cable one);
- backup battery in case the AC will go dead for a while;
- Camera...
And here lays my problem... every day im working with micro 4/3 lenses, i dont want to buy an expensive body for this project (for shure not something like the GH4). I was always using manual lenses for timelapses, but those old ones (m42 etc.) dont fit the idea of wide angle with 2x crop :/
Question: Is it smart to consider a compact camera for timelapse that will last 6 months (one RAW every 10 min - yes, i know that will be a lot of material to deal with). If not a compact, im thinking about entry lvl DSLR like Canon 1200D or Nikon D3200 (thats the max price im willing to pay for that body)
Maybe You could recomend any camera - best with integrated interwalometer and ofcorse with an option to plug in to AC power.

Thx for any sugestions

Get the cheapest Nikon DSLR with biuld in intervalometer (they usualy have one)
Best to deal with external power.
The biggest chalange is probably the housing and the condensation water.

For the housing I want to use a hermetic 1,5mm steel power box - of course with a sealed glas for the lense. It will stand there during the winter (it may be +5C like this year, or -20C) so I'm planning to heat up the glass with something like this:

to get rid off condensation inside, snow and water drops outside.

Im worried more for the light changes - day/night/day/night - its imposible (for me) to calculate it for 6months ahead Ill end up with aperature priority and just let it go... :/

and what do You think about Panasonic Lumix DMC-GF6K?
It has inside an invalometer and WiFi with "endless memory" option

No go for me, get a cheap Canon and use ext intervalometer, if your Nikon lose power the intervalometer needs to be re programmed, where as on a Canon once the power comes back it will carry on shooting again. Also the cheap Nikons only gives you 999 images on the internal intervalometer - resulting in going to the camera very often.

DIY can certainly be rewarding, and many photographers have gone this route. Pelican cases can be made to work, there are a few electrical housings that can do the job, etc. The difficulty is in the details. Internal camera mount. External mount that can aim the housing. Battery charger electronics, power supply electronics for the camera, the intervalometer, and the router.

Or, you could just buy it all
Photosentinel, Erdman, and of course Harbortronics all make systems that will do pretty much everything you have listed.
