Mobile internet allows cameras to become live broadcast studios anywhere there is coverage so while not a primary cinematography application definitely a TV camera application :)

"... the cool thing about the mushroom is that it can multiplex.

Could it be spam? As i don't see any purpose for 3G/4G in a camera.

Do you have foto-documentation of the build process online? And/or footage?
I would love to see your 3d prints and early assembly's :)

look at this A7sii Mod: http://www.centralds.net/cam/?p=7911

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.

Some updates on this front:
Last ccc @vup @leftshift and me decided to build a cheap development version of the Beta.
We wanted to have a cheap camera to be able to develop soft- and hardware for the Beta without the need to invest a lot of money.
Research was done, the cheapest Zynq FPGA development board was found, the cheapest suitable CMOS with okayish documentation was picked and we designed a first Interface PCB to connect the sensor to the FPGA dev board. We build FPGA designs and wrote some software and in the end we had the first still images. The first prototype of the AXIOM micro was built.
However, the initial PCB was quite rough and had major problems (we were doing serious PCB design for the first time in our lives).
This led us to the creation of a second revision, which now is able to shoot moving images, has a proper lens mount and some case.

We found this.

@Gookfilm how do you want to connect the handle to the body electronically?

Awesome, that's perfect!

Scrolling back, I noticed you said ‘cool idea’ about the extra bottom hole a while back. It didn’t make it into the current revision though.

Snap, totally forgot about the Compact Shell! Which is kind of a cage, I guess. And cages are... You need to buy a cage or extra rails for more mounting points with every new camera you buy these days. It would be great if cameras had all the mounting points themselves. Saves both weight and money.

Hi Iwan.

And maybe add an extra 1/4” hole on the bottom end of the camera, right underneath the 1/4” hole on the right hand side while you’re at it. A rail there could allow my wooden side handle to be attached.

Thanks guys. For the camera to work without a cage, I really need at least two 1/4” holes on either side, vertically aligned. So the right hand side has got that covered, the left hand side doesn’t. One extra hole down below would allow a Nato rail to be attached and then we’d be home free.

More details: UP 2 Squared with Intel Pentium Quad Core up to 2.5Ghz N4200 with USB3 OTG, 1x SATA, 1x mPCI-e and 1x M.2 2230 E-key starting at around 320$ excl. taxes.
Dimensions: 85.6 x 90mm

another interesting candidate: http://www.up-board.org/ai-edge/up-core-plus/
no price or details on the expansion modules (SATA, PCIe) yet though

Added those to the doc. Any other questions let me know and I'll ask all together during next contact.

Is the foam ESD safe?
Is it conductive?

Looks good!

Dimensions: W11" x L10" x H7"

Yeah, well of course this is something that the industry wants you to do. Considering the number of Betas out there, maybe just write up a simple declaration for each country where the product has been tested with a super official looking checklist, get it signed by the "tester" and someone from the organization.

i like it..

hey cool :)

This is the first sketch of the pcb that i made. it's 18x72mm, to fit atop of 4 18650 cells.

Here's a page for the build - https://wiki.apertus.org/index.php/AXIOM_Beta/Plugin_slots

agreed, lets do that

Another interesting bit here, however I am aware is not what we're after...

Thanks DanBetaMan for the finds. We need some kind of high speed storage interface (SATAIII, M.2, etc.). The Renegade doesn't seem to offer that.

Thanks for posting it RexOr

Great finds!

Great finds, raymond.lutz, thanks!

Eh just passing by... (was surfing the net for the Numato Opsis: FPGA-based open video platform

Sounds great! Way to go!

Welcome to the boards.

From Wiki for posterity:

spring loaded individual 18650 cells. would that be an option to avoid DIY and legal issues? is it secure enough without soldering?

Maybe soon: https://www.theregister.co.uk/2017/05/24/intel_thunderbolt_3forall/ :)

No nothing ! You don't have to be "association member" to have datasheet and licensing ?
They released the information in february, but this is all i know !

Do you have any documentation about the UHS-III physical layer?

Given that better stick with a Sony, Anton Bauer, Panasonic, or other manufacturer solution.

Another point I mentioned already but feel need to put emphasis on now: If we here collectively develop a new battery solution the result will very likely remain an open source DIY kit for tinkeres and people interested in building their own experimental battery assemblies. Due to the regulations and certificates requires for bringing new battery products to the market we will most likely not be able to afford making it a real retail product..

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?

Hi everybody,
I asked to steadxp if they can say to us which component they use. No answer yet but i will tell you if i have one !

is it possible to cover a smaller battery (8 cells) and big (16cells) with the same electronic design?

Yes and no. The way i throught the design was in modules of 4 cells.

I think the following needs a bit of context:

would you like to design the battery exclusively for the axiom beta (box shaped) enclosure or also to fit on the bigger (and more power hungry) ergonomic enclosure version as well?
do you think it make sense to combine it?

@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

What about future UHS-III ? write up to 624 mo/s, better than Cfast2.0...
No card/slot on the market for now (maybe i'm wrong)
But still a good solution if it will be backward compatible with UHS-II.
Probably SD association can give more informations ?

:O it's not open source!

Note that we are using Eagle 7.7.0 which is basically the last offline/old-license version before Autodesk took over.
Also note that our long term plan includes switching to KiCad which has made great progress since it gets the CERN treatment.

What software do you use at Axiom to design the PCBs?

I finally made the Eagle work on my computer, i have to say, is almost unusable compared to older version of Eagle.

Fenix sells individual batteries and also chargers.

@Menga i would opt for the 'less waste' and cheaper cells option ;)
do you think that using 16 cells instead of 8 would be also possible with the same pcb?
