  • On one similar display I was able to inverse image simply by taking it apart and flipping over the polarizer. On another similar display it didn't quite work that way because the polarizer wasn't cut at 90 degrees but some odd angle, so I had to get a piece of polarizing film I cut myself, rotated to get the best image.

  • The flux is what has a shelf-life, the metal in the solder lasts nearly forever. For instance, the bars they use for wave solder won't have an expiration date but the flux does and is often refrigerated to last longer.

No public wish lists :(
