More Info, how to and  in detail pictures coming soon!  ( Yeah I know i am terrible with how to s sorry :( ) 

Heltec T114 Variant also coming soon!

 

The Node can house a Faketec DIY node  or a Heltec T114 ( Later will be released after the faketec) 

The node utilizes a water drainage system away from the antenna base.

Only run it in client mode! even as it acts as a repeater / range extender for TAK use! 

As ATAK does a lot of sending receiving it could be necessary to override duty cycle in the settings to keep it going!

Waterproof tape for main power switch and reset button: ( to make it 100% watertight even so the switch itself is closed off  but still could oxidate when exposed to humidity/ rain)

Main part, Top and Crown all feature a  small notch on the outer edge  that has to line up  when put together.

Water tight stripe of tape goes over the reset button hole and power switch on the side once its turned on to prevent water to enter the case.

TPU Sealants ( printed in red on the pictures) go on the outer three screws on the TOP cap, the hexagonal goes in the SMA connector pass through on the inside of the top cap, the big triangle TPU seal goes  in between of course where top and main part meet.

Heat resistant silicone  to glue the solar panels on the case. ( make sure you put a closed ring of silicone around the cable openings in the case to prevent water to enter that creeps in behind the panels!!)

superglue to glue the antenna base on top

Thin wire to hook up the main power switch  and reset button,  faketec/ heltec to the battery protection PCB.

2 component epoxy to fix the main power switch and reset button into the  case. (test fit right after with 18650 cell to make sure it does still go in smoothly as it sits right behind it, its also effective to shave off the excessive epoxy putty as long it is soft)
