Crack The Code - purim

Overview

Mishloach Manot (English term: "sending of portions") are gifts of food or drink that are sent to family, friends and others on Purim Jewish Holiday.

What we have here is a unique treasure box based on the famous game Mastermind. To crack the code (or reach the "treasure" :-)), there are two options:

A. Solve a logic puzzle related to Purim.

B. Play an electronic Mastermind game.

I have redesigned https://www.the-diy-life.com/crack-the-code-game-built-into-a-diy-safe-puzzle-box/ (Michael Klements), Created Puzzle Box Mishloach Manot with the following changes:

• Extended the box size and split the wiring to a different compartment.
• Use ESP32 processor instead Arduino.
• Add symbols related to Purim - purchased in ShutterStock.
• The box can be cracked by like Mastermind like, or by Purim related riddle which yields a numerical answer.

Humorist video I made with my kids on the usage (in for now Hebrew, sorry).

Project description

Solution paths

A.A logic puzzle related to Purim

"Good and bad, at their core, may share similar traits and origins. But that's just what appears to be true at first glance"

Note: The solution is numerical, and requires some knowledge in Hebrew and Jewish culture, so you can optionally skip to the 2nd method of solving

B.Mastermind game

At the beginning of the game, each player chooses a number of several digits, when it is customary to choose a four-digit number, repetitions of digits are prohibited. For example, 1234 is a valid number ('0' is also considered a valid digit).

The game is conducted by a series of guesses, after the guess the ESP32 processor reveals to the player with red LEDs, the number of correct digits and location, and green LEDs, the number of correct digits (the LEDs do not reveal the position of the digits).

Green LED - a situation where one of the digits in the guessed number is the same as the digit in the original number, and is placed correctly.

Red LED - a situation where one of the digits in the guessed number is the same as the digit in the original number, but is located in a different position.

Operating Instructions

• Connect the socket to the plug (how is it possible without??)
• Move the power switch on the right side up.
• After the opening screen and the LED display appear, enter a number
• Changing the number by turning the dial.
• Confirm the selection by clicking on the dial.
• Repeat until 4 digits are complete.
• Wait for Red/Green LEDs indication.
• If the 4 green LEDs lit, the internal lock will open and show number of rounds till completion.
• Another push will lock the box again.

Laser Cutting

Note: Unfortunately I cannot enclose all the dxf files of the laser cut as they include purchased ShutterStock images but the raw box was created with the following web tool: https://en.makercase.com/

Attached thought, *.dxf files I can legally attach.

Summary

It was really fun creating this project, and I particularly enjoyed the process of adapting it to the ESP32. I would like to take this opportunity to thank Michael Klements from DIY for allowing me to share the modifications I made here.

Some people may question the combination of spirituality and technology, but it's just a part of who I am. I'm eager to connect, share, and discuss with others who share similar perspectives.
