🤣🤣Silly Ass Ave I am DEAF. Love the idea
Not a bad idea, especially since hardness is usually relative anyways, I just want to know which of my knives are harder I don’t need to know exactly the hrc, may have to make one of these.
thats cool ..
Genius idea about dropping a bollock
I don't care if it's been done before! I'm going to make an open source version of this, code and all! That sounds fun! 😎
Could you use an old gramophone diamond tipped stylus cartridge as a sensor….less than £10 on Ebay…
An Uncle Bumblefuck beanie with a propeller?? Shut up and take my money!
2020 I want to order 10 rulers…. if only you'd make em again
Und den….
Great freakin idea, and the size really makes it handy, cause the circuit components and a small batter added to that would be nothing! Get these done partner, I would love to have one! Don't forget to include a holder for the ball bearing while not in use.
Did this ever get followed up on? This was a great idea!
