yes. So a few weird issues.

  1. image height at 72, 30, 10 all look the same, taking up I’d say 90% of the blade, and centered top to bottom. Emitter and tip are dark.
  2. Tried image at HEIGHT=144. Well, that’s causing the board to crash after boot.wav plays. Even got a squee-of-death once of the 4 tries. Board doesn’t come back unless BOOT+RESET each time.
  3. Went back to HEIGHT=10 and works fine, although again almost full blade.
  4. When it does work, the blade shows spots of the image WHILE off, when clashed or even on its own sitting idle.
    So we broke something maybe, or it’s something buggy we’re just finding now or ¯_(ツ)_/¯.

I don’t see why altering wiper would do anything. It seems we just double scale it, unless I see this wrong, but the recipe calls for wiper first, then pnmscale via netpbm. THAT’s the spot we’re setting the $HEIGHT, then onto hex creation last.
So wiper makes it 800x144, then pnmscale takes it down to something like10 from my example.
