This is my 4 digit sequential PIN system with 28 segment LCD style display...

Visit the project page here- ... e-display/

The PIN is fully programmable via a set of levers.

Each digit is "scrambled" with an "X" for added security.

Consists of 3 buttons,
- Cycle number (1,2,3,4,5,6,7,8,9,0)
- Enter (enters the current digit)
- Reset (resets the device)

The heavily over-engineered 2x3 seamless door as seen in the video is just for demonstration purposes and is another one of my mini Redstone projects. This PIN system could potentially control ANY Redstone device, or be combined with command blocks to change the weather for example.

90% complete - works perfectly but I am adding a pin decoder to allow many different pins. I will be attempting to turn this into a 20 vault bank.

ok, so this is pretty awesome. i wish it wasnt so big though. im looking to incorporate some kind of redstone display into a project of mine, but that is definitely too big.

but maybe i will find a place for it anyway, thats too awesome to pass up.

Thanks, I know it is big. I can probably shrink the system to a degree, as this is only in the "alpha stage". I still have to add the multi-pin / multi-out circuits too, so that is going to take up another 2 or 3 chunks. The main of the bulk is taken up by screen connections to the decoder.

Also it does have a slight lag between the button being pressed and the display updating, (about 2 seconds,) but again this is unavoidable due to the length of the connections to the screen.

Really this would work best in the side of a large hill, or underground.
