Deceptive Dice

Overview

The "Trick Dice" (an electronic dice with a hidden cheat function)

is normally a regular electronic dice, but it has a hidden cheat function. If you roll a 1, 3, 1, 4 in sequence, and then land on the cheat number, the next roll will always be the cheat number. It can be used to fool children.

A demonstration video can be found on Bilibili.

21 Shenggong LHS-Multifunctional Power Module

A multi-functional 12V to multi-gradient adjustable amplitude power supply module built using voltage regulator chips such as LM7805, LM2596R, and AMS1117-3.3.

In this project, I redesigned a 12V to multi-gradient, adjustable voltage power supply module, referencing the design of @不想写代码的我的设计.
This module utilizes voltage regulator chips such as LM7805, LM2596R, and AMS1117-3.3 to convert the 12V signal into a multi-functional power supply module capable of outputting 5V, 3V3, and 1V~12V adjustable voltage signals. The module can be used with a battery to input a stable 12V voltage signal via a power connector. It then uses these voltage regulator chips to convert the 12V signal into an adjustable voltage signal with integrated outputs of 5V, 3V3, and 1V~12V.
This module can be used in various electronic design projects requiring multi-gradient voltage signal sources such as 3V3 and 5V.
