Interestingly, your typing video sounds very different compared to the other supposedly same keyboard.

This one i mean.
Any idea whats the cause?
Not having the top case can affect the sound.
Indeed. Also, it seems like that in the video OldIsNew did not bottom out the switches. So we can only hear the leaf spring sound.
Just an assumption. Nothing certain.

Last night I was trying to figure out how to integrate the speaker and volume knob into this project. The circuit is a bit over my head. Anyone out there feel like dropping some knowledge on me? I tried to make a schematic of what I see on the PCB.

By the way, this speaker is LOUD. Even on the lowest volume it's pretty loud, but crank it up and your neighbors will think you're testing your fire alarm. At least that's what my girlfriend thought I was doing.
