Looking at the Blackmagic, I suspect that a thorough consideration for ergonomics would set us apart from them.

se6astian: I know it wasn't you, but looking at it did remind me

and it's a weird thing that blackmagic does, not having the device fit well hands/be usable without looking at the screen

true, but the specs just sell their product, even if they make it in the most akward ways ;)

sure

he does like the 3 coloumn text layout, but thinks the interruptions of videos/images are a problem

it does look quite pretty

too many breaking points in the text

do you think a solution would be to group the images and text blocks together more

what size screen are you viewing on?

resolution?

More vertical resolution definitely helps with this one

on my 1920x1200 screen the document feels like it flows better than on my 1366x768 one

damn internet connection

doe apertus.org work for you?

actually I can ping them but they dont seem to do what they are supposed to

se6astian: works for me

I guess I will just wait a bit and hope the problem solves itself

ok, please do ;)

good morning everyone!

I've uploaded two more examples, one implementing a primitive register file via gpio and another connecting the hdmi i2c for use from linux

http://vserver.13thfloor.at/Stuff/AXIOM/hdmi_i2c/

there is also an info script which shows various registers and bits

Hello!

I was hoping you could help me something stuart recommended with the PCB

parse errror, please rephrase :)

I replied: In some areas this is impossible to do, does it help if I connect ground pins together and make several vias like in this image?

and to that Stuart replied: - Better, but the top layer copper pour that's attached to ground will likely take care of alot of this. You might be able to remove the traces in favor of the lower impedance thermal ties to the ground pour. Keep in mind that you want thermal ties to ground for component pins on the top/bottom layer, NOT a completely surrounding connection. The solder process

I don't really know what that means now ;)

what are the blue dots?

I think he suggested to make one GND via for each sensor pin

*idea

you basically want as many direct connections to the ground plane as possible

but in the area as seen in the image there isnt enough space, so I wanted to know if its better to do it that way (with several vias spread around and the actual pins also connected together)

why are they so tiny?

or are the vias huge?

the socket pins are rather small SMT

well, they look like half the size of a via on that picture

they are rather tiny

not sure if they are supposed to be that small though ;)

let me check the andon datasheet

"we have over 5000 products and cannot provide a single pricelist"

hehe

rollerball socket: 0.47mm

0.026" via, 0.008" hole

hmm, yeah, 0.2mm drill and 0.66mm pad

is there no footprint available for the sockets?

you have the CMOSIS-ANDON 'data sheet' at hand, yes?

email?

the -414T4 on the right (middle of the page)

but, directly below you see how the socket is soldered

there is no chance in hell to get a reliable contact with a 0.30mm diameter footprint

not specific to any type of pins

but what happens to the spike of the pin, in the mounting options box it looks like it melted away ;)

here you see how solder, pads and pins relate in SMD

Ah I see what you mean

and stuart also refered to Thermal pads

in expresspcb that is a via option, creates a cross like non copper area in the pad

you use them to reduce heat propagation

and which diameter?

no, you don't want thermals on the sensor pads

s/not/not only/

good point

the price is the same

how do you know that the SMD parts do not interfere with the socket?

we have the size, and the pins, but beyond that, all I see is a rectangular area

the SMD parts are 0.8mm tall if I remember correctly

it could be that while the pins have 2.8mm space, the frame directly touches the pcb

after all, something is holding those pins in place

how this something looks like, I have no idea ...

I emailed it to you on June 20th

indeed, sec

now the question is, with the window marked 'optional', what does that mean?

to my understanding that there are 2 products to order (with/without window)

but you can definitely forget about soldering parts near the socket pins

at first I had most of the capacitors in the socket area on the back of the PCB, but Stuart recommended to move them to the front to reduce via inductance

true

-) change image socket pads to bigger pads

-) move caps to back side
