12:56 | plusieurs | Bertl, S3bastian : hi, I'm the E.E who contacted you yesterday
| |
12:56 | S3bastian | Hey there
| |
12:56 | plusieurs | fine ?
| |
12:57 | S3bastian | Stephane, right?
| |
12:57 | plusieurs | yup
| |
12:57 | S3bastian | perfect
| |
12:57 | S3bastian | how are you?
| |
12:57 | plusieurs | fine, struggling with DBs
| |
12:57 | plusieurs | so, what can I do for you ?
| |
13:01 | S3bastian | we can definitely use another electronics engineer
| |
13:01 | S3bastian | but what exactly the next task could be Bertl will know best
| |
13:02 | S3bastian | as you probably heard we finished the hardware of the alpha hardware
| |
13:02 | S3bastian | that is a image sensor to FMC adatper
| |
13:02 | S3bastian | *adapter
| |
13:02 | S3bastian | now Herbert is working on the software (and hardware if you define FPGA code as hardware)
| |
13:02 | S3bastian | do you haev FPGA experience as well (VHDL, etc.)?
| |
13:02 | Bertl | morning everyone!
| |
13:03 | plusieurs | not a lot in FPGA
| |
13:04 | S3bastian | ok
| |
13:05 | Bertl | welcome plusieurs!
| |
13:05 | S3bastian | ah perfect timing, hi Bertl
| |
13:05 | Bertl | plusieurs: I've seen snootlab.com, are that your designs there?
| |
13:05 | Bertl | (or some of them :)
| |
13:06 | Bertl | S3bastian: timing is everything :)
| |
13:07 | plusieurs | Small part of them. That's a company that I help friends to build during 2 years, on openhardware. I was more on the B2B projects side (snootlab.net or goggle "AMS-IX + snootlab" for the pdf at RIPE)
| |
13:07 | plusieurs | biggest projects, biggest technical specs
| |
13:08 | Bertl | okay, can you point me to some urls, my french is really terrible :)
| |
13:08 | plusieurs | http://more-ip-event.net/presentations/2012/MoreIP_May2012_Arien.pdf
| |
13:08 | Bertl | just want to get a feeling what kind of projects you already worked on
| |
13:09 | plusieurs | this one was my latest big project (big = >4months)
| |
13:10 | Bertl | the schematic and board design was done by you, yes?
| |
13:10 | plusieurs | http://www.thalesgroup.com/Portfolio/Documents/Brochure_Compact_Airborne_Threat_Surveyor_CATS_Helicopter_05-10/
| |
13:11 | plusieurs | yup. That was fun to do that project. First commercial product doing 100GELR4 over 40km, and we put 8bit uC inside for the lulz :)
| |
13:12 | Bertl | nice, what tools do you use for schematic input and board design?
| |
13:12 | plusieurs | kicad :)
| |
13:12 | Bertl | excellent choice! do you know your way with eagle as well?
| |
13:13 | plusieurs | not a lot, but CAD tools are mostly the same, just tools, so it's just a matter of time to be efficient on it
| |
13:14 | Bertl | I've been trying to get away from eagle to using kicad but I haven't really managed to make the transition yet, although I'm still optimistic
| |
13:14 | Bertl | did you happen to have a look at the adapter board we designed for the axiom alpha prototype?
| |
13:15 | plusieurs | look this pres @ ohm2013
| |
13:15 | plusieurs | https://program.ohm2013.org/event/296.html
| |
13:16 | plusieurs | Bertl: not yet
| |
13:16 | Bertl | nice
| |
13:17 | Bertl | well, maybe that would be a good start then. I always appreciate input, despite the fact that we already have the hardware (PCB by OSHpark and assembled at home)
| |
13:17 | plusieurs | nut kicad is really pain in th ass for managing libraries/creating new models+footprints etc
| |
13:17 | plusieurs | in this way, it seems that eagle is better
| |
13:18 | Bertl | back when I started with PCB design, there was no real alternative for Linux
| |
13:18 | plusieurs | ha, I started on ISIS/ARES when I was 15. god that was crap !
| |
13:19 | Bertl | but since cern is actively interested in kicad, they are making quite some progress in all areas
| |
13:19 | plusieurs | right
| |
13:23 | Bertl | so, maybe check out the adapter first and let me know what potential issues, problems, bugs, etc you find (please do not hold back, we are trying to improve stuff here :)
| |
13:24 | Bertl | because it might be that we actually want to build a few more prototype adapter boards in the future
| |
13:25 | plusieurs | all right. Schemas, docs, specs on your website ?
| |
13:26 | Bertl | sec
| |
13:27 | Bertl | http://vserver.13thfloor.at/Stuff/AXIOM/cmv12k-adapter-v1.0.*
| |
13:27 | Bertl | the .sch and .brd are eagle schematic and board files
| |
13:27 | Bertl | (you can use the free eagle version for mac/windows/linux to view)
| |
13:28 | Bertl | the .tar.xz and .zip are the layers as PDFs
| |
13:28 | Bertl | the .pdf is the schematic as PDF
| |
13:29 | Bertl | axiom_alpha_*.png are images of the board being assembled
| |
13:30 | plusieurs | ok
| |
13:30 | plusieurs | specs ?
| |
13:31 | Bertl | well, we have a datasheet from cmosis (for the sensor), the open documentation (schematic, layout, etc) from the ZedBoard and a number of inofficial datasheets from the FMC connector
| |
13:31 | Bertl | the FMC spec itself is not available for free
| |
13:31 | plusieurs | ok
| |
13:31 | Bertl | S3bastian will point you to the documentation we have
| |
13:31 | plusieurs | thx
| |
13:32 | plusieurs | do you actually have trouble with this adapter ?
| |
13:32 | plusieurs | or dindn't tested yet ?
| |
13:33 | Bertl | the basic problem was to connect half of the LVDS data lines (for dual side readout) and all the necessary control lines of the sensor with the zedboard
| |
13:33 | Bertl | so far everything went smoothly with the hardware, we had two minor issues with the board but they could be worked around
| |
13:34 | S3bastian | datasheets: https://github.com/apertus-open-source-cinema/alpha-hardware/tree/master/Datasheets
| |
13:34 | Bertl | ah, maybe add the zedboard stuff there as well?
| |
13:34 | S3bastian | https://github.com/apertus-open-source-cinema/alpha-hardware/tree/master/Zedboard-Files
| |
13:35 | S3bastian | and more information about the zedboard processes in our wiki: https://wiki.apertus.org/index.php?title=Axiom_Alpha_Prototype
| |
13:36 | plusieurs | ok. I will follow that : <Bertl> so, maybe check out the adapter first and let me know what potential issues, problems, bugs, etc you find (please do not hold back, we are trying to improve stuff here :)
| |
13:39 | Bertl | excellent! feel free to hang around on the channel and just ask if something is unclear
| |
13:39 | plusieurs | will do
| |
13:40 | plusieurs | 'll start by read and understand then go
| |
13:42 | Bertl | good! just don't waste time trying to figure something out when it's simpler to ask ... there will be a delay on IRC as not everybody is around all the time, so you still got enough time to figure it out on your own :)
| |
13:42 | Bertl | no problem with pasting a question and then answering it yourself
| |
13:43 | S3bastian | many thanks! let us know if anything is unclear as Bertl said!
| |
13:45 | plusieurs | thx guys
| |
13:46 | Bertl | and welcome to axiom alpha! \o/
| |
13:47 | plusieurs | hahaha, wait my first contribution before saying that :)
| |
13:47 | plusieurs | are you all from europe ?
| |
13:48 | S3bastian | yes
| |
13:48 | S3bastian | Austria
| |
13:48 | Bertl | well, actually no, there are folks from the US as well
| |
13:49 | Bertl | but S3bastian and I are from Austria and the majority is from somewhere in Europe
| |
13:49 | S3bastian | Sasha_C is from Australia for example
| |
13:51 | S3bastian | ok gotta go for a bit

16:04 | S3bastian | hey!
| |
16:04 | S3bastian | lets start by just entering all positions we can come up with in the spreadsheet
| |
16:04 | S3bastian | camera head only for now, no modules
| |
16:04 | S3bastian | no NRE
| |
16:04 | S3bastian | only per unit positions
| |
16:05 | Bertl | hey philippej! how's going?
| |
16:06 | philippej | Hello Bertl doing fine!
| |
16:06 | philippej | and you ?
| |
16:06 | philippej | (lot of work curently, but it will be quieter in a few weeks)
| |
16:06 | Bertl | great! thanks! I got the first sensor data in the morning
| |
16:07 | philippej | hohoo !
| |
16:07 | Bertl | LVDS test patterns but data after all
| |
16:07 | philippej | the sensor can provide test data ?
| |
16:08 | Bertl | yes, there is a trainings pattern for the LVDS channels (which is required to adjust the delay and bit order)
| |
16:08 | Bertl | it's not what you consider a test pattern, I presume
| |
16:09 | philippej | great, so you already managed to get this data at the furious speed the sensor runs at ?
| |
16:09 | Bertl | i.e. it is a well known bit sequence (up to 12 bits) which is transmitted on each LVDS channel
| |
16:09 | philippej | I see
| |
16:09 | Bertl | yes, receiving it at 300MHz
| |
16:09 | philippej | great news!
| |
16:09 | philippej | it means the electrical connections can cope with the speed
| |
16:10 | Bertl | looks like, and all channels are there :)
| |
16:10 | philippej | congratulations!
| |
16:10 | philippej | on the first board run
| |
16:46 | philippej | left the channel | |
16:53 | S3bastian | ok, I think we are thought
| |
16:53 | S3bastian | just in time
| |
16:53 | S3bastian | many thnaks
| |
16:53 | S3bastian | this will be a good thing to add to the business plan
| |
16:54 | Bertl | just remember to multiply everything by 2
| |
16:54 | Bertl | (or at least two :)
| |
16:55 | S3bastian | for the retail price, sure, more than 2 :)
| |
16:56 | Bertl | no, for a realistic calculation which holds in case not everything goes as expected :)
