__anton__: Basically all FIZ gak needs those rods, as well as matte box etc.

__anton__: So not only the bottom, but also that aspect. Then there is top plate for accessories and, more importantly, underslung plates for Steadi etc.

troy_s: so you'd say modelling everything on Arri Alexa is a safe bet?

__anton__: That hole system is virtually universal.

__anton__: Look up Ronford Baker quick release plates.

God.

Rebelj12a: Right. I will bite because I am feeling energetic. So you are saying that an independent filmmaker has enough money to buy a matte box kit, filter glass, follows and FIZ units, and custom quick release plates.

Yes, not FIZ units, I dont have those.

I have custom quick release plates for the DJI ronin and Redrock Micro.

__anton__: I said Alexa simply because they offer specs

troy_s: and that was very useful, thx

__anton__: You will find the exact same holes for mounting rod plates and such on every other camera.

troy_s: I understand

troy_s: is 6x6 also a filter size?

I dont doubt they exist

Rebelj12a: just googling Redrock, they sound expensive :)

Tiffin and Mitchell make them.

Not the most satisfied with the shoulder/studio rig

Redrock is pretty indie.

Yeah I could have had the whole shoulder rig for the RED for alot less than the RedrockMicro

Yes. Most folks with RR buy the gak.

(Rental house depending of course.)

Hence the need for compatible rod placement mount points etc; the most important aspect is the other gak that makes a camera actually useful for cinema.

Either way I took the advice of a friend of mine whom I no longer take advice from so.

Sadly, most of the vendors out there are trying to sell crap.

Indeed, especially one whos disabled, Which the shoulder mount was supposed to help. So much for that.

Houses on the other hand, generally always have a few peeps with their feet in the indie scene and really want to help.

Most shoulder kits on set are... A piece of foam.

A good matte box and a piece of foam work tremendously well.

I can honestly tell you theres only one other active video company in the state, that advertises online (i.e. doesnt already have corporate contracts). Who has better equipment than I do. Which is pretty sad to be honest.

Rebelj12a: What state?

I'm in Wisconsin

they got cranes and stuff. Otherwise everyone is pretty closed doors so I assume they have corporate contracts.

and quite a few production houses

Hey if you have time could you send me some links or names. Id like to check them out.

In any case, I didnt have any support then where I am so. In any case, looking back id definitely get a lighter rig. More versatile and probably less expensive than redrock.

__anton__: And yes, that is the locator pin hole.

__anton__: That doc would probably be valuable on the Wiki or Phabricator, as it has the correct distance to lens from plate.

troy_s: yes, I'll link the doc from wiki of phabricator.. just figuring out the best place.. wiki has changed a bit today :)

Yeah and ive turned to fabricating my own cables as well to save.

Rebelj12a: NAC is pretty cool and probably willing to let to you come in and play with the gear to get comfortable with it. When we rented for our school we got to go in and get a little workshop and play with the gear

Thats cool wescotte if I can ever get in the area id definitely be up for that.

Ask troy, i just google searched it lol

Throwing that in the wiki for sure.

As it is im just trying to get used to the DJI Ronin, although I think mine is defective.

i.e. sensor board <- header -> interface board <- cable -> beta board

the 'cable' needs to transport 36 LVDS pairs and about 16 CMOS I/Os

I mean microzed?

yes, the microzed connects directly to the beta board

I will have a schematic with hard values soon

some round some flat

but I guess the cables can only be easily terminated with IDC headers

Bertl: Jerk. Like every second word out of you is jargon too.

We just come from different jargon junk piles.

__anton__: That doc is hugely good for measurements though. If there is a like F65 or other cine camera PDF it would be great. This measurements should match though.

probably the best approach would be a flex PCB with the very same connectors soldered on

(AKS is actually "all kinds of s*it")

It is all expensive really. Even the most useless crap is expensive, and more expensive if you don't have it.

a screenshot from youtube

__anton__: Sony tends to be more conservative with their information, hence why I suggested Arri originally.

Pretty sure the distance on those two 3/8ths is the same as the Arri.

__anton__: No clue. But the housing's design will need to accommodate that existing gear.

if they were IDC then the interface board could be replaced by a couple of cables directly

the purpose of the interface board is to preprocess the sensor data

so replacing that is not the best idea :)

could these be two long IDC connectors?

I mean two connectors, 64 pin each

and yes, you could probably put cables there as well, but they would need to have a lot of wires and reasonable shielding/impedance

the currently planned connectors have 144 pins each

36 LVDS + 16 I/O = 94 pins?

first, that's the interface board to beta board LVDS count

and finally, you need to get power to the boards as well

one of the main purposes of the interface board is to allow having different connections between interface board and beta board

so if you want to put a cable somewhere, then there is the best place

http://solutions.3m.com/wps/portal/!ut/p/c1/04_SB8K8xLLM9MSSzPy8xBz94NS8-NBg_Qj9KLP4IC8Py1BTI2MDf3NjFwPPYD83SydjZ-NgIwP9ggxHRQAhtIRH/?PC_Z7_RJH9U5230O73D0ISNF9B3C3SI1000000_nid=30BSKT7WBKit6Z44P5GPWMglMX7WG02RWSbl

precisely

lowest IO count, and both sides are completely under our control

what frequency are those cables designed for?

distance is 20 cm max

but the cable can not be shorter than 22cm

22cm is the length of the twisted section

you can only attach the connector to the non-twisted section

but there's no shielding between the pairs

the missing shielding and the round cable makes me a uneasy

a flat cable with shielding wires would probably be much better suited

you just won't be able to use the full bandwidth

non-round cables exist, though they are pretty wide 67mm for 25 pairs

Bert: thx for advising me on that

even worse, the original plan was to put the sensor on the beta board

hi there

Do I need to register to the wiki to participate?

And is there a way to see the Screws in the PCBs so that one could actually do a drawing?

or you can look at them in this interactive viewer

"3D View"

http://lab.apertus.org

http://lab.apertus.org/T66

any ideas/opinions/thoughts are welcome

I saw the different needs from people eg devs and photographers. So my Idea would be to mount the electronics on a tray that is screwd dircetly to the back of of the lensmount. So it possible to change the style of the housing really quickly all you need is a lens mount somewhere.

great

currently its not planned to have adjustable back focus

we just make sure the lens mounts have perfect FFD

always keep in mind you need a more accurate measurement device than the actual tolerance you want to achieve. so you would need to have a 0,005 exact device to make sure that your +-0,01 is ok. this means most of the times 20C° in the lab and so on.

Yeah I'm just waiting for the e-mail... and found out that you are using inventor.

2013 I think

should arrive instantly actually

great :)

thank you is this by mail?

updated

morning folks!

back

please help research CNC mill products

I've sent email to microproto twice, they haven't replied yet, maybe they are out of business or simply not interested in selling a mill :)

added

would it make sense to get a 5 axis lathe/mill combination?

http://www.pocketnc.com/products/

the 5 axis means it can move in three axis and rotate in two?

http://www.youtube.com/watch?v=qLvMFH7wknw 4:21 is interesting

please add anything you find to the wiki page

http://gizmodo.com/compact-ssds-that-outperform-the-fastest-usb-flash-driv-1649957047

updated: https://wiki.apertus.org/index.php?title=Cooling

toxitobi: a little restructuring and beautification would be nice

If USB drives exist though they should exist at that size as a part separate from USB controller.

btw, 'My solution' is not that self explanatory as one might think :)

yeah, use proper lists, etc, wiki is rather simple

Added pictures to my public album. Lens circuit board from a 28-80 canon EF lens

Plus lens gearing mechanism

do you get an error message?

No way (that is clear) to get a browser window

please file a bug report with a short description

Okie

yes, it should be

Phabricator navigation is awful

hello

evening daFred!

or potentially also production parts later on

the http://www.pocketnc.com/products/ looks ideal from the concept

they are preparing a crowdfunding campaign :)

yes the pocketnc looks good but they show carving pinewood...

the body looks massive, but the rotary axis with a timing belt? I dont know!?

I was quite impressed by the tormach website

bcallebaut|2 said he has a "semi professional CNC" maybe he can post his opinion when he reads this.

2nd hand is also fine

yes

without 4th axis :)

the PC is the least of my worries :)

great

http://karner-dechow.at/ufItemInfo.aspx?a_id=502&i_id=62103&s_id=0

tempting though :)

agreed

only stuff that would require lots of work :)

Although I'd rather have a 3d printer and do cast forging but for smaller pieces that's less than ideal.

cast forging and 3d printer? tell us about it

maybe you should designe a test object and calculate the cost of manufacture with various techniques

Are you guys planning on going touchscreen on the LCDs?

touchscreen is not planned but might happen

I assume you guys want something light weight for the UI toolkit?

err I mean do you think you need something lighter than gtk/qt?

no X either?

SDL or something directly on top of OpenGL?

huh?

I don't follow... What does does the LCD have to do with OpenGL?

good night

wescotte: who would do the OpenGL then?

what GPU?

maybe I was wrong

if you want to run MesaGL on that, it will probably end up being _very_ slow

Yeah do you need openGL?

se6astian|away: You have a broken link on the website. The banner on top that changes... When it displays the Alpha/Beta/Gamma with Developemnt/Goal/Image Sensor/Resolution/Output... it's a broken link to https://axiom/

Rebelj12a: I think the resources for any HTML5 browser might require a powerful UI widget lib too.

Would it? I mean alot of websites and mobile are turning to webm so im not so sure about that. They are using it because of the low overhead on mobile apps

most mobile browsers are GPU backed these days I think

hmm
