Some interesting things I found recently that I think others might be interested in:
- A video of a cool 6 bit adder made from wood and marbles — I think this will be really useful for explaining binary maths to my kids when they show an interest. (More detail).
- A wooden combination lock. There is also a page describing the build of the lock.
- A repeatable morticing jig for a table saw, with full build instructions. He also built a cool box joint jig with plans available.
- A pistol for playing jenga with an unfair advantage, that’s my kind of cheating.
You’ll notice all of these videos are from Matthias Wandel. He has a YouTube channel and seems like my sort of geek. I am sure there will be more links from him as I work through his 7 years (!) of videos.
