i like your approach a lot!
the super8 idea ist great, especially for artists and hobbyists who want to get in touch with AXIOM.
Also this has the opportunity to get people on board because it is a low threshold first contact to the project.

christophvarga added a comment to T736: Battery System.

Using 4 cells with a single pcb on top, forming a unit of battery.
This unit can be stacked to form the size of battery you want, in 4, 8, 12, 16 cells and so.

that sounds good.

From the electronics perspective there is no major change between the two. You can desing different cases that hold the amount of cells each camera needs.
I think tho, that we need to find a common connector and holding for all the batteries. So you can interchange them between different models of cameras.

agree.

What i see a little tricky is the hot swappable battery.

What about having a dual battery mount (two smaller batteries (8cells each) instead of one 16 cell battery)? would it be hot swappable then if you exchange one after another?

@Menga yesterday we worked on the design of the more mature and ergonomic camera body for the beta. a few questions popped up: is it possible to cover a smaller battery (8 cells) and big (16cells) with the same electronic design?
please evaluate if the outer measurements of the battery could change to something more flat like: 130 x 80 x 40 mm

christophvarga added a comment to T736: Battery System.

@Menga i like your design approach. does the hight and width (-the space for the hdmi/sdi connectors) match exactly to the backside of the beta enclosure? what about separating the cells in two groups and have one or two screws in the middle instead of having them on the sides. in that case we could also allow the package to be mounted under the camera and still be abel to mount it on a tripod. does 21700 cells also fit inside?

Does it need a 'PIC' to have status LED's directly on the battery? that is something which is really useful (checking batteries when they are somewhere in the pocket..)
What are the extra costs going for the more complex battery design? We can have different battery capacities so that you won't need to own more than two batteries.

NO! that is a mistake, if you are using rods, than you put them ON the rods behind the camera.. usually..
and if there are no rods it is good to attach it to the body of the camera directly to make one sturdy body.
don't you think so?

hi, what about such a hot swap- double battery design which fits under the camera or somewhere on the rig?
for 4A it is also good to have two batteries so that (the cheap ones) don't get hot too much.

I searched arround a while for sunlight readable displays and the best which comes up are transreflective-monochrome ones. Just now i held my audio recorder with it's monochrome LCD in my Hand and i am impressed by it's readability.

direct behind that button there should be an easy to understand explanation of the communication structure and the actual topics i think. this explanation should happen through clear and good design as through words. it should show an overview of the vivid community i think.
