Hoiktronics: Programmable Passcode-Protected Door + Video Tutorial

[DicemanX]

My latest hoiktronics build is a programmable passcode-protected door. The passcode is a 3-digit number that gets displayed on screen when entered into the keypad. The passcode can also be removed from memory, and a different passcode can be entered into memory - quite a feat compared to the previous passcode mechanism I designed! The mechanism repeatedly makes use of ZeroGravitas reset mechanism posted here:

The first 8 minutes of the video below showcase the passcode-protected door, and the next 50 minutes go into a lot of detail about hoiktronics in general and how the components of the passcode mechanism function.

Wiring:

Protocols:

Enter 3 numbers into the keypad. If the correct passcode is input, the door will open and a green light will turn on. If the wrong passcode is entered the door will remain closed and a red light will turn on. The C(lear) lever clears the input number and closes the door if opened.

To reset the passcode, first the R(eset) lever is pulled, and then the current passcode is input. This removes that passcode from memory. To input a new passcode into memory, the R(eset) lever is pulled again, and a new 3-digit number is input.

To reach the passcode-protected door, enter B9 in the teleporter hub.The current passcode is set to 993.

Safe to say that your wiring has reached new levels of 'totally bananas'. And a 1 hour long hoiktronics lecture too! I'll totally embed that video in the "What is Hoiktronics" guide, unless you add it to your reply first :

Reserved for commentary.

Probably better to just add it to the main post if you'd like, since it's not necessarily the case that players wishing to learn about hoiktronics will read through the subsequent replies. The opening post will keep them busy as it is .

The next guide I was planning to do is one for the ALU+converter. There are tons of small mechanisms to explain, and the logic of how the pieces fit together needs to be clarified.
