I have a bunch of 8mm film reels I want to digitize.
Any good methods for that? I don't mind if it involves building something. I tried capturing off a screen, but the results sucked.
Some howtos use cameras to photograph each frame, but afaik that kills the shutter soon.
Others point to a flatbet scanner project, but that's only for 35mm I think.

There's a very good method an old friend told me about. See, back in the day, there were those so called "labs" that scan your film professionally using special equipment. Some of these are still available, so you should be able to exchange money for this service.

Labs charge you through the ass for it though. I had a lab quote me 60e starting price, 24e for handling, and 3.45e per minute not including soundtrack.

You already determined it's difficult to do well. You either need special equipment or a whole lot of time and spare shutters. You expect labs to do that for free for you and the six other people in the world who want to digitize 8mm film?
There's probably a commercial grade film scanner that will handle 8mm reels, just find one and decide whether you'd rather pay that price or pay a lab to do it.

When I use the price quites from >>2961430 as some sort of reference, I'm in a range where I consider a diy solution.
I don't mind if need a couple of stepper motors and maybe a raspberry plus camera module which takes 3-4s per frame.
The films are decades old, I don't care if the scanner runs without much attention for a few weeks to create eg 960x720 image sequences. These thousands of images I can convert with ffmpeg.
My problem is, how to get the optics right without spending a few thousands?

I'm not arguing that it's overpriced, I'm just saying that it's expensive as fuck, so unless you really, REALLY want those old videos digitized at high quality, a lab job probably isn't worth what it costs. Rigging a DIY system if you're skilled enough or finding an old projector and recording off a screen are the only practical solutions that don't cost a fortune.

screen, white wall or large piece of paper, is going to be your best option.
The problem is going to be frame rates, 8mm and super 8 run at 18fps and video typically runs at 30, 24, or 48fps, the off set will give you flicker.
my school had a projector that had a slider that could bring the frame rate from 18 down to 12 and gave pretty good results. I was thinking of trying this by plugging my projector into a dimmer switch. it might work.
then just run the camera at a matched or higher frame rate than the projector, ie 12-24fps / or 15-30fps.
your motion will be slower but it will correct the pulsing of light and dark. some editing programs will let you fix the speed.

tried that, but the resutlts were... far from acceptable. that's why I'm thinking about a frame-by-frame solution
OP you're going to end up getting them scanned or leaving them to rot.

The first result I found charges between €0.80 (for >180 minutes) and €0.99 (for < 90 minutes) per minute.
Plus €15.00 for each DVD (max 90 minutes per DVD).
So that's €74.40 for 1 hour.
Quite reasonable IMO.
Only kinda shitty they don't let you download the result instead of putting it on a DVD in 2016.
