Last crawled date: 4 years, 2 months ago

This is based on the binary marble adding machine from this web site and is based on the plans from the site: http://woodgears.ca/marbleadd/
There is also a great YouTube video explaining how to use it: http://youtu.be/GcDshWmhF4A
It's a great way of teaching binary numbers and it is also a lot of fun to watch the marbles fall!
