Hey ITGeek,

Wow, your fantastic hobbies are keeping you busy.  Your weather station seems like it's better than Pagasa.....he, he.  Love your drone HD coverage of your neighborhood -- very nice residential area.  

I'm also into electronics (21 years in the US navy), Qualcomm telecommunications and then bench tech at a local casino.  These days, one needs to be forewarned about pending doom and gloom, especially around the Korean peninsula.  

Well done sir!  Respectfully Jake

Bicycle seat adjustment clamp. I have also used them on tie rod ends. Is there a bicycle shop in your area?

Thought I'd give an update on my WX/webcam setup.  I was using a 20 ft length of 1" rigid galvanized steel for the mast.  I then had 'T' connector on top with (2) 1 ft, 1" sections attached perpendicular to mast.  One side had the WX station (~1kg weight), while other side had the webcam (~7kg weight).

The project was only half way completed, with lower section of mast was anchored using 7/16" concrete bolts and U-brackets into the balcony.  I also used 3/8" nylon rope tied around mid section of mast, anchoring ends of rope to corners of the balcony.  

Then a big storm storm came up before I could anchor top section of mast to side of house.  Disaster almost struck as 25-30mph wind gusts rocked the top of mast back and forth.  Couldn't do much but watch, due to lightning.  I then noticed the concrete started to crack were anchor screws were.  So I tied additional rope around bottom section to temporarily secure.  The stress eventually broke a chunk of concrete off balcony, exposing the concrete bolt insert.  Good thing I had attached additional rope during storm or whole thing would've fallen down.

So now that I know my easier solution isn't strong enough to withstand moderate winds, I will be using a 10m length "flag pole" or "small street lamp" for mast, anchored to poured concrete block on ground.  Will have local metal worker make bracket so webcam can be bolted directly to side of mast.  Weather sensor will be mounted on top of the mast.

With this setup, it'll easily hold up to anything less than CAT 4 typhoon force winds.

Sounds like a plan. Hope you don't overlook the type of fasteners you use - grade 8 galvanized or stainlesss screws. Otherwise they'll just rust away in the humid climate. A couple of thick coats of rustolium paint over them will help too. 

Also, instead of nylon rope how about using braided or twisted wire rope? Of course with the appropriate clips and turnbuckles.

Personally I would just make my own.It`s not that hard to do.
