Sorry for the bad quality.
My grandfather had this in his office. He worked as a computer engineer so I initally thought it was a zoomed-in picture of a computer chip or something, but maybe it is something large.
He’s not alive anymore so I can’t ask him. If somebody can help me out, that would be great.
Not sure why people think this might be huge. You can clearly see solder spots in the lower right and standardized holes in the upper left that are probably small screw sized. I’d guess all those rods are standard computer pins, just really long. I think it looks like some sort of pre-breadboard breadboard project to me.
It looks to me like something big ontop of other big things.
Those “screw holes” in the top left look like crane hook points for moving the big things underneath.
There is a picture elsewhere on the post that shows similar divert-holes with a person standing through it.
And it looks like a pile of junk near the top of the photo.
There are odd diverts on the left and right sides.
I bet they are ladder/access points, which would match the scale of a person standing through the hexagonal diverts, and would match the crane hook points.
Regardless of scale, its certainly a heat exchanger and not anything IC or circuit related
