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.
