Amazing work, and so inspiring! The size difference compared to the G9ii made it all worth it! Lately I've been converting a few old 5k iMac's to work as external displays, and I had a thought about making my own housing for the display instead of using the iMac chassis. This gives me some motivation to look into it further!

Care to share what driver board you have used?

Sure. The exact seller I purchased from doesn't have the product, but in AliExpress if you search...

"For iMac A1419 A2115 5K LCD Screen Driver Board LM270QQ1 LM270QQ2 Retinal Control Motherboard 5120*2880 QQHD HDMI DP Type-c"

...it will come up with what I have used in the last few conversions.

Though I have seen Quinn Nelson (Snazzy Labs on YouTube) released a video recently that shows his process which is a bit more involved, but better. Apparently his method is better to remove risks of power surges from the controller board (I haven't experienced it yet...!), but his method also retains the speakers, and relocates the I/O inputs to be more accessible.

Earlier quoted context omitted.

The volume for physical cameras is low and shrinking. The companies can't justify putting nearly the same investment as smartphone companies selling 100x the units can.

The volume for cameras like this was always low. Even in the days before you had a camera on your smartphone, people were buying Polaroids, compact cameras with a small lens built in, or disposable cameras. They weren't buying something more complicated unless they were hobbyist photographers.

Those compact cameras with a built in lens still funded the R&D for the expensive cameras. They can all run the same OS and software, etc. Smartphones have continuously chipped away at the bottom tier of cameras to the point where even hobbyist photographers use smartphones. And only the absolute top tier of very expensive cameras still exist.

> the Lumix lenses are crippled on Olympus bodies Are they?

A lot of the Leica-branded lenses have an aperture ring that doesn't work on Olympus bodies. Besides that, both brands have proprietary lens + body stabilization that only work if the lenses and bodies match.

Don't they have adapters for all that now?

The haters will hate, but tap guides are great (e.g. https://biggatortools.com/v-tapguide-faqs , but even a block of hard wood with a clearance hole drilled in it works fine). Unless you're tapping something super tough (306?), Amazon taps are fine for hand tapping. Go in straight, use a good lubricant.

I've got two of those tap guides, one for US and one for metric. They're great. Also for drilling since I don't have a drill press at home. I've examined cheap taps under a microscope. Maybe they are of varying quality, but the ones I got had burrs all along the cutting edges. A tap that I borrowed from a machine shop was flawless in comparison. So maybe the middle ground is caveat emptor . Another trick for tapping…

All good advice above. I’ve tapped 1000’s of holes and haven’t broken a tap in 50 years, and I have nothing to add to the above. Berkeley Physics Dept. student machine shop training.
