This is the overall image with the highly modified leaf blower, the autotransformer, and the sheller box.
Seeds are dropped into a hole in the (now) top of the blower and are blown into the sheller box at high speed, I am figuring about 120 mph, and the shell cracks on a slam board inside the box. The meats fall to the bottom, and the hulls blow out (everyfrigginwhere).

This is the inside of the sheller box, with the back of the angled slam board on the right side of the picture. The plenum top has been removed for the picture.
After the seeds hit the slam board and fracture along the seam, the meat falls to the bottom and most of the hulls blow out the open left side of the box.
In this picture, you can see some meats and a few unbroken seeds at the bottom of the box.
This is still a work in progress, and adjustments to slam speed and airflow through the box are on-going.
