#apertus IRC Channel Logs

reason is simple, because of inheritance the structs were marked as not initilaized, have checked it, but had no solution after several tries, when data is uninitialized then it is stored in the .bss section of the PIC32, but it's not big and i didn't want to mess around with it, especially when i expect the icons to be data blobs and nothing else

BAndiT1983: thank you, will check that out :)

it's an incredibly tiny subset of the lcsc catalog

good morning

Spirit532: interesting, can you tell us more about your experience?

They took care of everything - I emailed them the BOM, they asked some questions, gave me a pretty transparent price list and substituted some sources(genuine parts, cheaper)

interesting, pcbway is on our list of potential pcb manufacturers

morning folks!

Spirit532: yeah I know

There aren't that many parts left after passives, about 30 I think, so thats manageable

I think around 15-20 usd on top of the order

around 5% I think

so they don't overcharge

because pcbway is a lot more realistic than jlc

I haven't heard anything about low quality, but yes being limited to certain parts is suboptimal, but also what makes it so cheap. And for this board I am ok with populating the ~30 parts jlc doesn't do myself, if I don't have to care about the 500 passives that jlc can do

and then hook it up via a axi lite to axi full bridge to the ps7 block of the zynq

but ours is rather... unfinished ;)

anuejn/vup do you have any screenshot from the layouting or any preview of the Micro R3?

right, well maybe in a day or two :)

vup/anuejn how do you plan the mechanical side of r3 currently? in particular the lens mount ?

r2 was a bit difficult to attach to a tripod though

nope

well I could design one or more parts for you

is the image sensor still envisioned to be on a separate pcb?

what information do you need?

height of sensor above PCB plane

and where holes are located there

so the zturn lite dimensions can be found here: http://www.myirtech.com/soft.asp?id=847 and http://www.myirtech.com/soft.asp?id=945

bc. there might be different sensors

we need some way to account for that

I will think about the variable sensor height, could be an issue

but that will make the assembly a bit more complicated and requires more parts

and the same hole pattern?

se6ast1an: probably the same hole pattern, but bigger

washers can raise the mount above the sensor indeed but you create a gap for light to enter there then...

(extending beyond the short side of the zturn lite in equal parts

the washer would have to be a complete circle / rectangle around the optical path

that can be extendet in height

ah, one large washer, I see, thought one for each screw so 4

ah probably both

a 3d printed ring around the optical path

se6ast1an: the distance between the the mainboard and the sensor board is 6mm

(see https://github.com/apertus-open-source-cinema/axiom-micro-mechanical)

the pcb's are all 1.6mm thickness

so we have to atleast accomodate those two

and somewhere we have to fit the shield aswell, probably on the same side as the sensor pcb

also the sensor pcb size is something we need to think about

I think I have the rough setup done: https://cad.onshape.com/documents/119d4253b556f8944095c5ad/w/8cba5fbf62e83d916df2c99f/e/af78801fa9663719e0120078

<vup> I think for the sensor pcb, to a certain extend, the bigger the better, there are not a lot of advantages to keeping it small <- yes if you make it zturnlite sized you can use the holes for <vup> we also need to think about the mechanical attachment of the sensor pcb

ah, nice

self made

hold by the connectors and some sandwich force

ah found it: https://github.com/apertus-open-source-cinema/axiom-micro-mechanical/blob/master/pcbs/z-turn-lite.fcstd

se6ast1an: in our current mechanical setup this is not the case?!

off for a bit

back

in R2 the lens mount was screwed to the mainboard right?

but I wouldnt say its optimal as this puts all the mechanical stress on the pcb then

like with the emount adapter on the beta

off for now ... have fun!

where exactly is the / are the shields positioned at the front?

se6ast1an: yeah we thought about doing it similar to the the beta

and the ethernet on the zturn is pointing upwards?

ok

ah

yeah, currently the etheinet on the zturn is pointing upwards

the c mount to m4/3 adapter metal part, are you happy with that one so far?

off for today

good night
