| felix_ | Bertl_oO: is there anything i still need to do regarding the axoim photonsdi hardware design? today and tomorrow i'd have a bit of spare time to do some stuff if needed | 15:05 |
|---|---|---|
| se6astian | is the bom complete and the component placement decided? | 15:06 |
| felix_ | hm, i don't know hot the component placement gets exported to be used with the pick and place machine | 15:15 |
| felix_ | the bom should be complete; if you'd like to have that, i could look up the digikey order numbers | 15:16 |
| se6astian | we are not using the pick and place machine for prototypes | 15:17 |
| felix_ | ok, sounds reasonable | 15:18 |
| se6astian | for boms we use octopart, very convenient | 15:18 |
| felix_ | ok, i'll look into that | 15:20 |
| felix_ | which option should i use if a component order number is different for the chip packaged in a tube or on a reel? | 15:32 |
| se6astian | whatever you prefer | 15:33 |
| felix_ | uh, when i build a prototype i usually order the chips in a tube, but for small series using a reel might be the better option. i never did a (small) series on my own; only had people taking a design i made and getting it somehow into production without me looking at what they exactly did there | 15:38 |
| felix_ | ordering chips on a reel adds a bit to the cost when you don't order a full reel | 15:39 |
| se6astian | right, then tubes sound like the better option | 15:43 |
| felix_ | ok, if that works with the pick and place machine, i'll use the tube version | 15:44 |
| felix_ | hm, i'm not sure if the other version will be a reel or cut tape | 15:46 |
| felix_ | uh, oh, bad news: the TPS82085 is currently out of stock :( last time i looked they were still in stock (some other modules from the same series were out of stock though) | 15:54 |
| felix_ | hope that you still have some spare ones of that chip; iirc you used those on the new revision of the power supply board... | 16:00 |
| felix_ | have you any preferred resistor/capacitor/led manufacturers? | 16:01 |
| felix_ | hmm, i probably should have a look again at the google spreadsheet inventory thing. can you send me the url to that page again? | 16:02 |
| se6astian | multicomp mainly | 16:02 |
| se6astian | this is our mainboard bom: https://octopart.com/bom-tool/KFuQ0Ext | 16:03 |
| se6astian | inventory: https://docs.google.com/spreadsheets/d/1x48-cnjVwFRppDpS9nMnWvQw4nn58A94JXBJd5nqmbQ/edit?usp=sharing | 16:03 |
| tpb | Title: Inventory - Google Sheets (at docs.google.com) | 16:03 |
| felix_ | thx | 16:03 |

| felix_ | https://octopart.com/bom-tool/qme05BU4 will add the passives and leds either later today or tomorrow; had to do some customer support in the meantime and now it's time for some sport | 17:04 |
| Bertl_oO | no worries, the parts have already been ordered a few days ago ;) | 17:21 |
| Bertl_oO | I made some assumptions on the ferrite beads and capacitors but otherwise it should be what you had in your BOM a week ago | 17:21 |

| felix_ | ah, ok; so i don't continue with the bom | 20:09 |
| felix_ | yeah, i was quite busy last week. osfc and ibc were wirth the visit though | 20:10 |
| felix_ | *worth | 20:11 |
| felix_ | at ibc i talked with some companies making caxial connectors; apart from samtec and amphenol there are also https://www.cambridgeelectronics.com/ and http://www.coax-connectors.com/ | 20:12 |
| tpb | Title: Home - COAX Connectors (at www.coax-connectors.com) | 20:12 |
| felix_ | might also be worth a look for the hdbnc-bnc cables | 20:12 |
| felix_ | oh and i found it interesting that some company has a sdi card that's not based on an fpga, but an asic. didn't think that the volume of chips needed was high enough so that an asic is cheaper | 20:14 |
| Kjetil_ | I guess ASIC have become a lot cheaper | 20:18 |
| felix_ | oh and for the axiom remote it might be worth looking into the tasters used in commercial professional audio and video consoles. sure they are rather expensive (maybe 8-12 euro per piece), but those are really good | 20:19 |
| felix_ | hm, yeah, if you don't need the newest process, things might have gotten more affordable than i remembered | 20:19 |
| se6astian | "worth looking into the tasters used in commercial professional audio and video consoles" which are those? | 20:21 |
| felix_ | i'll have a look when i'm back home; haven't brought the stack of paper i got at the ibc to my office yet | 20:23 |
| * felix_ writes that on his todo list | 20:23 | |
| se6astian | thanks | 20:25 |
