I have been working on my electronics. Tonight I just got the very first reverse board to work. The train is reversing as we speak.
I got four more wall warts for power supplies.
I finished up the arc board but no arc.
This toaster project is cooking me.
One good thing this week. My son built an egg landing device from a board, three dowels, an elastic, a piece of paper, and half of a plastic Easter egg and duct tape. The egg survived the drop from the roof of the school. He said it spun down and landed. Actually 9 out of 20 survived that day.
Wonders never cease.
I forgot the pipe cleaner.
