The Super-Chuffer Revisited aka the Super-Chuffer II

The Super-Chuffer has been around since 2014, and has proven to be quite popular.  However, there are a couple of things that I've always wanted to do, so I thought it was a good time to revisit the design and see if I could do some tweaks.  There were three things that I identified right off the bat that I'd like to change, and one unused feature that I decided to remove.

  • Make the footprint smaller.  Even at it's current small size, I have issues at times stuffing it into some upgrades.
  • Fix the light sensing so it works with all versions of the R2LC as well as the earlier LCRU and LCRU2 packages.
  • Monitor the smoke unit power to cut all power to the smoke fan if the smoke unit isn't energized.
  • Remove the opto-isolated chuff output as the way this unit is used, that's never been useful.

After a little time at the computer and workbench, enter the next version of the Super-Chuffer, the Super-Chuffer II.  I'm happy to say, all the original design goals were able to be realized.  The new version will be more than 30% smaller in footprint and about 15% thinner than the existing board.  It now supports the additional features I mentioned, and you'll notice that HD2 has been removed as it's no longer needed.
