|
| 05:58 | Bertl | morning folks!
|
| 05:58 | Bertl | hey sab_123!
|
| 05:59 | sab_123 | hello
|
| 06:05 | sab_123 | you guys are based out of Vienna?
|
| 06:11 | Bertl | se6astian is in Vienna, I'm nearby, other folks are spread all over the world
|
| 06:13 | sab_123 | Bertl, cool
|
| 06:13 | sab_123 | Bertl, sent you a pic of the board
|
| 06:15 | Bertl | I presume you're the new intern then :)
|
| 06:15 | sab_123 | yep
|
| 06:15 | sab_123 | thats correct
|
| 06:16 | Bertl | looks nice! what clock rates do you use un U4 and U15?
|
| 06:17 | sab_123 | It is configurable
|
| 06:17 | sab_123 | depends on the camera I2C conf
|
| 06:17 | Bertl | maximum
|
| 06:17 | sab_123 | right now using parallel mode
|
| 06:18 | Bertl | i.e. what I want to know is: for what maximum speed/clock/data rate is the board designed?
|
| 06:19 | sab_123 | i/p
|
| 06:19 | sab_123 | between 6 and 27Mhz
|
| 06:20 | sab_123 | o/p - It is supposed to do 98Mp/s
|
| 06:20 | sab_123 | so you see the length matching
|
| 06:20 | sab_123 | It is 4 layer
|
| 06:20 | sab_123 | Signal
|
| 06:20 | sab_123 | VCC
|
| 06:20 | sab_123 | GND
|
| 06:20 | sab_123 | Signal
|
| 06:20 | sab_123 | got some help for the board though
|
| 06:20 | sab_123 | FPC 0.5mm connector
|
| 06:21 | Bertl | yeah, I was wondering about the (excessive) length matching
|
| 06:24 | sab_123 | done in kicad
|
| 06:26 | Bertl | so you're now going to assemble and test it?
|
| 06:27 | sab_123 | thats going to be hard now
|
| 06:27 | sab_123 | I have to find some way to assembled this
|
| 06:27 | sab_123 | I dont have a stencil
|
| 06:28 | sab_123 | So I will have to get someone to do it for me
|
| 06:28 | Bertl | doesn't look too complicated, i.e. should be fine for hand soldering
|
| 06:28 | sab_123 | never soldered stuff
|
| 06:28 | sab_123 | especially SMD
|
| 06:28 | Bertl | are there parts on the backside?
|
| 06:28 | sab_123 | yes
|
| 06:28 | sab_123 | lots
|
| 06:28 | sab_123 | of decouling caps
|
| 06:28 | sab_123 | AMS1117
|
| 06:29 | Bertl | okay, so nothing really problematic there either?
|
| 06:29 | Bertl | like QFN or BGA or so
|
| 06:30 | sab_123 | no BGA
|
| 06:30 | sab_123 | TQFP 144
|
| 06:30 | sab_123 | Spartan 6
|
| 06:30 | sab_123 | i have to probably go to a mobile repair shop
|
| 06:31 | sab_123 | Those guys help me out
|
| 06:31 | Bertl | https://wiki.apertus.org/index.php/AXIOM_Beta
|
| 06:31 | Bertl | the blue boards were all hand soldered at some point
|
| 06:31 | Bertl | s/blue/purple (of course)
|
| 06:32 | sab_123 | how do you do it?
|
| 06:32 | Bertl | first, you need to know how to hold your soldering iron :)
|
| 06:33 | Bertl | okay, seriously, it is not that hard if you know a few tricks
|
| 06:33 | Bertl | but you should practice on a spare board with cheap components first
|
| 06:34 | sab_123 | if you have a stencil
|
| 06:34 | sab_123 | reflow is easy
|
| 06:34 | sab_123 | with hot air
|
| 06:34 | sab_123 | but dont have a stencil for this
|
| 06:34 | Bertl | well, yeah, but stencils are overrated for prototyping
|
| 06:34 | sab_123 | let me share an interesting SOC with you
|
| 06:35 | sab_123 | whats your email
|
| 06:35 | Bertl | the important thing for hand soldering is to know that liquid solder is a liquid with high surface tension
|
| 06:36 | Bertl | so you can do all the stuff you would do with any other liquid, like 'wetting' pads or pins, and 'sucking' it 'dry' with some fabric
|
| 06:36 | sab_123 | Bertl, are you:
|
| 06:37 | sab_123 | *email address removed*
|
| 06:37 | Bertl | obviously I am
|
| 06:37 | sab_123 | Well
|
| 06:37 | sab_123 | I didnt know
|
| 06:37 | sab_123 | Bertl vs herbert
|
| 06:37 | sab_123 | close
|
| 06:37 | sab_123 | but just wanted to make sure I dont send documents to the wrong person
|
| 06:37 | Bertl | you should read your email more carefully then :)
|
| 06:39 | Bertl | and I don't mind much, but usually it's not a good idea to paste email addresses in a publicly logged channel, because it will for sure get picked up by a spam bot sooner or later
|
| 06:41 | sab_123 | ah
|
| 06:41 | sab_123 | okay
|
| 06:41 | sab_123 | sorry
|
| 06:41 | sab_123 | :-)
|
| 06:44 | sab_123 | yes
|
| 06:44 | sab_123 | read the email now
|
| 06:44 | sab_123 | did you take a look at that chip
|
| 06:45 | sab_123 | the chip is about 3-5USD depdning on type
|
| 06:46 | sab_123 | (1Gb vs 512Mb)
|
| 06:46 | sab_123 | RAM is built in
|
| 06:52 | Bertl | yes, I've seen the chip (GM8136)
|
| 06:52 | sab_123 | ah
|
| 06:52 | sab_123 | okay
|
| 06:52 | Bertl | but I haven't found publicly available documentation yet
|
| 06:52 | sab_123 | i sent it to you
|
| 06:52 | sab_123 | right now
|
| 06:52 | sab_123 | didnt you get it
|
| 06:53 | Bertl | you have an url for the documentation?
|
| 06:54 | sab_123 | i sent the whole SDK to you now
|
| 06:55 | sab_123 | dont have something public,
|
| 06:55 | Bertl | so how did you get it?
|
| 06:55 | Bertl | (the documentation)
|
| 06:56 | sab_123 | do you have gmail account
|
| 06:56 | sab_123 | I would prefer to discuss it there
|
| 06:57 | sab_123 | or SKype

| 08:54 | John_K | hi Bertl
|
| 08:58 | Bertl | hey John_K! how's going?
|
| 08:59 | John_K | not bad, got our custom adapter boards back
|
| 08:59 | John_K | uploading a few photos now
|
| 09:07 | John_K | https://kelley.ca/temp/Mavrx/
|
| 09:07 | John_K | basically just RFE + PIC from Main board and no Dummy Interface board
|
| 09:08 | John_K | Z was getting too high for our enclosure with the Dummy IF and we needed the 90 degree sensor rotation
|
| 09:08 | Bertl | yes, I see, nice
|
| 09:09 | Bertl | I presume the image data is processed in system?
|
| 09:10 | John_K | captured and sent over ethernet to an ODROID XU4 with a USB3.0 attached Compact Flash card
|
| 09:10 | John_K | 3 Beta cameras to one ODROID
|
| 09:10 | John_K | each capturing at around 1FPS at the moment
|
| 09:10 | Bertl | I see, the gigabit ehternet is fast enough for you?
|
| 09:10 | John_K | only because our application doesn't need higher frame rate
|
| 09:10 | John_K | yes
|
| 09:12 | Bertl | nice to see the first real adaptation of the AXIOM Beta!
|
| 09:12 | John_K | :)
|
| 09:12 | John_K | after validation on it is complete we'll get the design files posted
|
| 09:14 | Bertl | excellent! would be nice to have an article about it as well, if possible
|
| 09:14 | John_K | that sounds good to me, will run it by the team
|
| 09:28 | Bertl | great! thanks!
|
| 09:32 | John_K | so you recently had a meeting about Gamma?
|
| 09:42 | Bertl | yes, we had an intermediate review from the EU
|
| 09:45 | John_K | financial / progress review? or some sort of design review?
|
| 09:45 | Bertl | progress and financial
|
| 09:46 | Bertl | went very well
|
| 09:46 | John_K | glad to hear!
|
| 09:47 | Bertl | I think an article about that is in the works
|
| 09:47 | John_K | from what little I've seen of it, gamma seems like a more complicated beast than beta?
|
| 09:47 | John_K | ah, nice
|
| 09:47 | Bertl | definitely
|
| 09:49 | John_K | alright, time for bed here. Good night
