Just in time for Christmas!

This would make a wicked geocache. I could see all the old people crying. LOL LOL :)

Cant you just, replace the atmegas main code, to set high every pin?

Cool hack! There’s a minor bug though…the vault_passwd_list array needs to be terminated with a NULL, similar to what you’re doing with the vault_cmd_set array (you can’t really rely on the compiler to do it for you).

Can’t wait till my kid’s old enough to do fun stuff like this with him :)

He should wire up the keypad, and add a set of 4 leds, and turn the front into a game of genius. 10 tries max, with a random password every 10 tries, or every successful try atleast. That way you can play with the vault without a computer. As a geo-cache, the old folks will still be able to use it too.

Since I can’t find a link for genius online, its a game where you have to find an unknown password, within x number of tries. You key in 4 numbers, and leds will light up, letting you know if you got a number right, and if you got it in the right spot.

“TinyCore allows you to start with a very basic graphical Linux Desktop with a terminal client and download just the packages you need from its online repository. Once downloaded those packages will be available whenever you boot it again. I won’t go into detail because it is quite straightforward,”

Yes, now THAT’s consumer friendly. I’m sure they’ll sell like hotcakes.

I think its called mastermind

Very fun project, I want to play!
I like to weld and have access to a CNC mill, wonder if I could come up with a hammer-proof version of this.

I just uploaded this to a spare arduino and having a hoon. Up to level 3, just trying to figure out the pin number.

@Whatnot
NO FUN ALLOWED!!

this project totally rocks! can’t wait to do it myself when i have the time
