this is a sample or trial layout for most of the items to be secured onto the circular microcontroller,
motor driver, etc. board that will be visible under the dome (not including some additional "shields"
that will be stacked over the one in the middle there).
It's not intended to go under water (as cool as that would be), I was just impressed enough with the dome
being of almost that kind of undistorted clarity for such a reasonable price..
I will be cutting away some underlying yellow/green board material (used to be a high-vis archery polo shirt of mine before
the glass and resin haha) to provide ventilation, as structural integrity allows in between the pcb's.
It wasn't perfectly logical to have some of the heat sinks to not be aligned vertically, but I'm trying to have this project
move along suitably and that's how much or what I had; it didn't fit and/or line up no matter what I did so I turned them
90 deg. and suddenly I had just enough aluminum fins to fit, some shorter I can act
like was because of the arc of the dome, lol.
Some of the wasted-looking vertical space will be filled with the additional shields stacked onto the Arduino and the top one will be
a UART WiFi module with a wee antenna poking up in the center nearly reaching the apex. I could fit it externally but I'd have
to send off for an antenna cable patch and for all I know there'd be loss (?)..
...but so yeah it just seems nice to me to get some ventillation in there since I'm on dry land, and esp. with what I've done with the horizontal
red anodized sink fins. I've got few couple more randomly scavenged scrap electronics to pull apart to see if I can cannibalize a wee
high performance fan or two that are maybe 1/3 the size of the once that cool my PC tower, for example.
