Is there any way to squelch certain threads from the spy view? Sometimes uninteresting but wildly active threads trump all over what I'd rather see. Yeah, I'd love to not see the politics threads in the spy. The only pointless bickering I want to see on Deskthority is about input device preferences...

Very cool-looking board. Shame the switches don't feel very good.

Man, they sure were stingy with the soldermask in East Germany. :lol:

Great to hear news on this project! I'm impressed to hear that it's working so reliably even in such unfavorable circumstances. Keep up the good work.

Now Apple "invented" it (or so people will say), and everyone will love it.

The Displaywriter controller has the same connector, but a different pinout for its matrix. It looks like the controller on this board is on the same PCB as the pads, which would make using an Xwhatsit controller very difficult. Just a note: the second sentence in that quote was about a completely ...

My guess is that the R stands for rheostat. Back when Alps started, that was a more common term than it is today.

If there's bare metal connecting a pad and a via, the via will wick up the pad's solder during reflow. This keeps solder away from the component, resulting in a poor connection, a tombstone, or generally something that could make boards not work. I really can't see an easy way to move that via though.

All in all, that looks like a pretty nice board layout. One note though: it's generally a bad idea to put vias in the middle of pads (except thermal pads/vias–go nuts with vias there!). They suck up solder, leaving too little for the component itself and creating a poor joint. For a component with b...

PLA has a huge problem of not dissolving easily, so solvent bonds are near impossible You must not be using the right solvent.
