Thanks Jasem, yes it is a vast improvement from the first one.
Paul, I didn't use any velour, wood panels painted black only.
@Magnus, I will contact you via pm regarding the weather station.
So for the new box I have spend many hours thinking about the new design. I know my first box had inspired quite a few out there. Magnus was too I believe (correct me if I'm wrong there), I saw his box and pinched the idea of having the linear actuators further apart from each other.
My first box had many flaws, for example the camera would hit one linear actuator, I had a leaky lid, the wood side panels did shrunk, the micro switches for the lid were inadequate. It had too many screws, too much wood, too many angle brackets.
I watch quite a lot of youTube videos about wood tenons, cutting wood, gluing wood etc...
The frame is wood, properly cut square, minimum amount of screws (I used probably a 10th if not less than the old box), wood glue was also used (damn this glue is super strong once fully dry). The inside panels are plywood, probably 4 mm or so, they are not structural.
The outer ones are aluminium composite panels, SUPER strong and SUPER lights.
Each panels are secure by 6 screws only at the bottom (3 each corners) and only 4 screws at the top. It takes 10 min max to dissemble the box.
The alu panels are actually stuck to the wooden frame using 3M vhb tape, go watch some videos about this tape, got to see to believe it really.
I had to design it with constraints in mind: had to "fit" the allowed/allocated space on the balcony of the in-laws, it HAD to fit 100% flat packed in the boot of my car (it fits with 5 mm to spare (witdh), no kidding.
I've relocated the solar vent/fan to the front where the sun would hit it more than when it was in the back. The wiring has been improved too.
I guess the only flaw in my design that I can think off is that I could have build it 5 cm longer (it's not quite a square, about 105cm/95cm)
