Will test the Windows installation too, but wasn't able to do it, yet.

I will report back! The cooling is the integrated heatsink with a fan slapped on it.

Hi... I'm a long time forum reader but this is my first post. I've read through this thread a few times, but it's not clear how I can order one or two of these interposers? Who is selling them- feipoa?
Thank you!

I will be making extra interposers at some point, but time keeps getting the better of me. As noted earlier, I'm not selling the interposer units, but rather, am giving them away in exchange for direct charitable donations to a registered charity (preferably one of my choosing). Can talk after I have extras in hand. Making one-off's is way too time consuming.

For anyone else wanting a pre-assembled unit, please wait until I have a batch of these assembled (probably November). One member made such a large donation [to a charity I selected], I felt more compelled to assemble a one-off. The problem with this is the doubling of time required. For the one-off, this is what my tracked time looked like this:

1.5 hrs: prep, e.g. pulling parts and cutting & sanding down pin strips
7.5 hrs: soldering socket, pins, and filtering caps
2 hrs: all other soldering + flux cleanup
1 hr: setup a testbed, run scope measurements, take photos, and disassemble the testbed.

Total: 12 hours.

I hope to get this down to 4-6 hours each unit in a batch, but its hard to say. Soldering the pins and socket takes the most time. The amount of exposed conductor on the PCB is quite small and makes heating more difficult. I needed to use a finer tip, which is OK until you reach a GND or VCC pin. Bent tips for the corners are best.

Unfortunately, the guy selling the narrow PGA168 sockets is now asking about $6 each (shipped). They used to be about $1.50.
