assembling a few more OtterCam-s3‘s today.

@janamarie@mystical.garden @evey@chaos.social @kouett@soc.kouett.net.eu.org oh! i expected around 2x as much, this is nice

[janamarie@mystical.garden]

@domi @evey @kouett I should add, they can be replaced with 0 Ohm resistors and there is an additional row beneath the receptacle to replace it with a 2.0mm pin header to move it to a second board. The pin-header also would allow for PoE, I planned for this already!

[janamarie@mystical.garden]

@domi @evey @kouett this is actually not even my original idea, the first version of the OtterCam is not the OtterCam-s3, but the OtterCam-z7, featuring a Zynq-7020 instead of the Allwinner-s3. I have had a schematic of that since 2020, started it in altium, moved to kicad, redid the schematic twice, once with a Zynq-7015, then the 7020 again with more modern parts in 2024/2025, couldn't bring myself to design the board in the end because I just couldn't afford it at the time and now here we are, the OtterCam-z7 will still happen, maybe soon even, but I kind of want to get the OtterCam-s3 to spit out an image first..

Weirdly enough, the z7 would probably have been a bit easier for me alone, I can use Vivado and write gateware, but I really am not good at doing embedded linux and V4L shenanigans

@domi @evey @kouett the OtterCam-z7 will be much more expensive :S

clearance..

[atna@eldritch.cafe]

@janamarie does it make alignment easier?

[palmandneedle@norden.social]

@janamarie ...is clearance, Clarence! If #BlondiHacks taught me anything

And dont call me Shirley

[janamarie@mystical.garden]

it boots!!! Soldering the BGA was much more trivial than anticipated, the QFN in the lower left corner was certainly worse…

next up: I think I will do at least a second board and uh, the sensor board, which contains the 'spicy BGA', the image sensor. It’s in theory as easy to solder, but it’s also a rather fragile part, one entire face must not be touched too much

[janamarie@mystical.garden]

speaking of…

this is how the image sensors were delivered. How does that make you feel?

[janamarie@mystical.garden]

@atna very! a press fit always is easier

@janamarie antistatic bubble foam

[janamarie@mystical.garden]

@nota hyperstatic foam!

@janamarie yesss

@janamarie .. hungry?

[erinrose@chaos.social]

@janamarie do you like that RJ45 socket? I’ve been looking for an SMD vertical one recently, but was put off by the all plastic ones (solely based on vibes)

(eventually settled for a mostly SMD metal option)
