As my dome finally is getting closer to delivery, hopefully in a few weeks, i'm starting to think about maybe doing dedicated 12v wiring at least, though perhaps i dont need it at least right off the start here.
In my build thread you can see that i basically have a 12x12 deck, permanent pvc 10" pier in the middle and nexdome to go around that. I created a just a bit bigger than a shoebox area under the deck for power bricks for now. Drilled a hole to allow air and wires through from the pier.
My mount is the cem120 but i also have a 7 port USB that i was using.
Here is a shot of the mount panels The central ones are input. And the one can take 12v 10amp on the center (dont have this supply). The bottom one has the brick it came with, 12v5amp. My thinking was i could attach the 7 port hub off the usb 3.0 port at the top, whereas the usb 3.0 on the bottom would go to my mini pc (19v mini pc btw).
So for right now i had ordered this basic brick off amazon:
Xenocam AC to DC converter, 12v 10amp $20 That would just power that secondary port in the middle for now and use the brick that came with the mount for the main power.
On that top right panel on the front is 5v1amp, sides have dual 12v1amp options and then on the left side there is 12v5amp on each max (2 of them).
What i definitely have to connect around the mount perhaps is the following:
Main power brick (OEM came with it) 12v5amp
Scope secondary power as mentioned 12v10amp (maybe the amazon brick for now).
Then coming off the usb 7 port ill have these:
USB power 12v3amp
Asi294 USB 3.0 + power 12v3amp
ASI 224 USB 3.0 (never at same time as 294 but 3.0 needed)
ASI 290mm mini USB 2.0
USB 2.0 to focuser
USB 2.0 on the mount for control (from mount to usb 7 port)
So if i plug the 7 port usb into the usb 3.0 i can attach it somewhere and just plug all usb's like i have been into the 7 port (or some usb 2.0 on the mount itself and all usb 3.0 on the 7 port, kinda a waste either way).
*****Now the 12v alternative wiring options:
So far i dont have any 5v needs but maybe i would one day?
I was thinking something like this power supply would do the job + wiring?
I'm not completely up on how these wire together, but its my thought that i could use an 8 port anderson power pole board like this for a mere $56 and just run a positive and negative from the 12v regulated power supply to the pier somewhere?
Then create or buy prefab dc 2.1mm? connectors to wire into this anderson board and send to where they are needed?
Then theres the whole debate of whether i just send power to all the devices from this thing or just feed a single 10amp12v to the middle panel on the cem120 and use the ports on the cem120.
I guess i have multiple options here, i'm hoping short term there is no harm in using the simple 10amp brick off amazon.
The other concern is where i'd put something like that regulated power supply in the dome itself, i guess create a small open ended plywood (1/2?) box and put it on the "wall" of the box, near the main power panel in the dome.
I'd also need to figure out the right type of wire (gauge etc) off amazon or similar to buy for the run from the reg. power supply to pier area (10 foot, so maybe 16 gauge, unsure)
Any thoughts/input here?
Thanks in advance
