phew, just returned from the fab lab ... almost another catastrophy ... but the parts for the case should be done now, unless I got something wrong with the design ...

good morning

Bertl, good to hear some progress, was the lasercutter again not calibrated?

(i.e. the watchdog circuit)

after playing that three times, I sent an useless and till now unanswered email to the only problem contact they have

fifteen minutes later, I disabled the watchdog :)

an hour or two later, I found myself in a solid cloud of sawdust

somebody had turned on the - as we now know - broken vacuum cleaner, which didn't have a filter anymore

ah before I forget, please try if the nikon ring really fits the plastic and the nikon lens, if it does I will acquire the second identical camera from the same seller for Gabe

well, it doesn't work with the aluminum lens mount, but only because the screws are different (i.e. the screw thread, not the position)

shall I test the bayonet part as well? or can we assume that this part works

says the person who told me that the lens systems work on all cameras :)

would be interesting to ask konstantin if he used the original screws or maybe replaced them with more common ones ...

morning PhilippeJ!

hi PhilippeJ

se6astian much clearer with the video

and thus allow a simplier casing

also, I'm sending you a link on a doc I'm curently working on :-)

Well, the sodimm locking mechanism cannot be accessed if it's at the bottom of the casing, wo I though some "sticks" to push them from the top might help, when you cant to remove a board. Think (a bit) like the car radio metal key antitheft system

long piece of nylon

hmm, ok I see, well requiring special tools is prone to problems

it could be done with a screw driver or a piece of wood, but we don't want people to ruin the connector board

btw, removing the locking mechanisms is not the best idea :)

digikeys has a lot of them

the key word is vertical, the right angle ones are the bad ones

20% more pins and they usually come in vertical by default

mini dimm is 82mm wide for the module so we would need to increase the size of the enclosure (not a big deal)

off to bed now ... have a good one everyone!

hi all

more information about "vita 74": http://www.vita.com/home/NewsandEvents/Events/Embedded%20Tech%20Trends/2012/Presentations/VITA%2074.pdf

very interesting!

very nice

VITA57 is around 25$ per piece

price is one thing, getting it to work (production proven) and developing the hardware the other... backplane, cases... are on the market...

the "vita 74" was just a information.... i know the connectors a costly... :-/

how many connectors are the target per modul?

btw, very interesting stuff!

it was never meant to be cycled a lot

thats a number that is pretty suitable for our purpose

thanks.... that i wanted :-)

for standard connectors

external connectors are a different story, some connectors reach up to 1500 mating cycles

Vita 74 looks lovely (http://www.vita.com/home/NewsandEvents/Events/Embedded%20Tech%20Trends/2013/PDF_Presentations/M11%20-%20VITA%2074%20Small%20Form%20Factor%20Systems.pdf )

true that

not cheap...

plus the mating part on the other side again 52$

3 modules = 300$

for 3 modules

agreed

I like the idea that the board itself can be plugged in a connector directly, like sodimm and pci, but is there an equivalent with high pin count, and not too expensive connectors ?

rated for 100 mate cycles

excactly that molex connector i have looked is <20$ :-)

ok, this is pcb to connector, not connector to connector

tyrone_, where did you find the matching price?

http://www.digikey.com/product-detail/en/0755940000/WM10252-ND/1956169

dirt, swear, dust and everyone can touch your pins

sweat even

mars_, those are meant to be inside an enclosure

its not meant to be reconfigureable in the field

the idea goes more in the direction of building a custom pc with PCI-e slots

but not on a daily basis

i missed the connector discussion... what is the price point of the system?

the pricepoint of the system where the connectors will go, I am afraid I dont understand your question

assembly of that kind can use solderless connectors from samtec

guesst do you have a link to those?

not that sorry

hey there

Yes, thaks o lot!

It was quite a big file,

indeed :)

what would you do differently

please take a critical look at everything I created

I did not look so deeply for the moment

ok

morning everyone!

hi Bertl

Did you buy the different part in shop, or did you produced them in specialised industry or in labs?

the CAD files I sent you have not been manufactured yet

ok, but you said the second prototype was ready few days ago

yes, the part of alpha proto

the nikon bayonet ring we took out of old nikon slr cameras

the rest is lasercutted PMMA and a bunch of screws and nuts

maybe because the exchange format we used is not for that purpose

Or partially et, as you know the dimension of your lens

(which is great as it is standardized)

(approximatively)

min 100, maybe more

so we will maybe not be able to continu to produce the parts by lasercutting? (first part is wrong)

the Alpha prototype is what we currently have, thats not going to be produced at all beside a few hand assembled pieces

what we plan to produce in higher volume is the Axiom camera

OK, I ask about that because as the quantity increase, we will have to produce more pieces externally

yes, to make things even more confusing ;)

Axiom camera produced externally agreed

Ben, do you have experience with aluminum molding?

drawings separated for each parts

high cost to produce mold forms, low cost for actual pieces, where is the break even point roughly?

For aluminium molding, I only studied it

Am I right expecting to require a 2 piece steel mold form that is likely to be CNC milled?

by mould

Which are the part you want to realised by molding?

probably 500+

If you plan to produce 100 pieces, you will choose a price affected to each part

More standard pieces used, cheaper is the final object

the external aspect wil not be good, but price will be OK

and for 500 if it would be cheaper

See you!

good night
