Small world @aeva . I am also into vintage electronics and have been thinking about how I will use the Glowforge to make something really ornate.
Here is my simple triode-pentode amp I built many years back using much less high tech methods. I was just listening to it yesterday thinking about all the options that will be opened up for making V 2.0.
One of my current CAD projects in planning for the Glowforge is an art deco stereo console. The majority of the structure will be conventional construction, but I plan to do lots of embellishments that are laser cut.
I have also been thinking how I can use the Glowforge to build a new set of electrostatic speakers. I decided when my kids were born it was a good idea to get rid of my existing set as the way I built them it would have been really hard to make them safe for (high voltage) small fingers. The Glowforge should be great for cutting curved acrylic spacers to make something along the lines of the Martian Logan design.
