> But nobody seems interested in making this stuff. I guess the community that uses Framework laptops isn't really capable of that level of hardware engineering (me included) and the companies in China doing hardware haven't caught onto making stuff for Framework.
I relate to your sentiment of wanting tons of modules, but I'm going to disagree on the skills of the community.
For some of these options (4k/eink screens for eg), you need such a panel to be available (panelook to search -> aliexpress/ebay to buy). SDRs, IMUs & sensors could be doable relatively "easily" if they interface via USB/PCIE.
There are lots of hardware tinkerers in youtube, hackaday and of course even here on HN. I'm a mechanical engineer with some electrical/electronics knowledge, and I could likely make a half-decent module if I had the time/money/reason/ethusiasm for it. There's a guy who's turned an iPad screen into the FW13 display (on the framework community). There are probably dozens of people who may read this comment who are far more skilled than I am.
If you are very keen to do this yourself, you might want to start with learning 3d modelling and building up from that (from a mechanical side). 3d printing metals with something like SLS is commercially (relatively) easy and (imo) accessible compared to say 10-20 years back.
