As the Super-Chuffer has been installed, one issue has surfaced more than any other. It seems folks have trouble with getting the headlight working. The solution is pretty simple, but easily overlooked. Since I was having another run of boards made, I also included a small change to make getting the headlight functioning easier. You will no longer have to add a capacitor or resistor across the TMCC headlight output to use the Super-Chuffer LED headlight feature, that has been included on the Rev. 2 boards that will soon be shipping. You can identify the new version by looking on the back of the board, it will be labeled Rev. 2 if it's the new board.
The installation instructions have also been updated to reflect some installation experience. In particular, if you're using an incandescent cab light, I've modified the connection to power that from track power so you aren't loading the Super-Chuffer power supply excessively.
As always, the Super-Chuffer is available at Henning's Trains on-line store at the previous link.
I've attached a copy of the Rev. 2 Super-Chuffer instructions to this post.
