Creative Clock – A Large Digital Clock Made from 24 Clocks and 48 Stepper Motors

This project was made by maker @joshr120 on reddit, inspired by ClockClock, but he didn’t want to spend a high price, so he decided to DIY one. This clock consists of 24 small clock faces, each controlled by two stepper motors, totaling 48 stepper motors. Although readability may be affected at certain moments (like 11:11), overall this design is very unique and attractive.

The highlight is creatively transforming the display of an analog clock into a digital clock-like visual effect, and it only requires a microcontroller and some shift registers to control all the drivers, costing about $200 to $300.

Despite a bit of noise when working every hour, this clock has been running continuously for over 6 months, and the author says he hasn’t grown tired of the noise.This creative clock is not just a time display, but a piece of art filled with creativity and technology.

Arduino Remote-Controlled Underwater Robot (ROV) Made from Food Containers

Imagine how exciting it would be to explore the depths of the underwater world! This project makes that dream possible – DIY a remote-controlled underwater robot (ROV).

This small ROV can be tested in bathtubs, pools, or nearby water bodies. Using Arduino, you will create a simple ROV with two motors, controlled remotely for left and right steering.

The highlight is that you can add various instruments or payloads as needed, such as installing a camera to capture precious underwater moments. But don’t forget, this project requires some experience with Arduino and preparation of certain materials and budget. In the end, when your ROV sails freely underwater, all the effort will be worth it!

A complete parts list, circuit diagram, and example code can be found on the Science Buddies website. This project is perfect for hands-on and exploratory friends; you can even use it to revive an old GoPro camera that has been gathering dust in your cabinet!

Beach Cleaning Robot

The beach cleaning robot is a maker project designed by students from the University of Colorado Boulder, aimed at providing ocean enthusiasts with a technical yet affordable DIY solution. This robot can operate autonomously or be controlled remotely, has over 15 hours of battery life, and costs less than $450.

It is not only fun to use, but also allows users to further modify and customize it according to their needs. More importantly, the 3D printing materials used in this project, PLA and TPU, are biodegradable and environmentally friendly.

The entire project focuses on education and affordability, providing a detailed materials list and assembly steps, allowing anyone interested in electronics and robotics to try making their own beach cleaning robot.

Transform Your Phone into a Mobile Arcade

Want to play retro arcade games at home? Now you can DIY your very own mini arcade! This project will teach you how to use MAME4Droid and your phone to create a mini arcade cabinet.

First, you need to print all the parts, then solder the controller and buttons, assemble the model, and connect the circuits. Additionally, the highlight of this project is programming the Arduino as xinput commands, perfectly compatible with the MAME emulator on your phone.

Finally, print beautiful arcade artwork on sticker paper and stick it on your mini arcade to make it look more realistic.

DIY your personalized arcade and relive those classic games!

LEGO-Compatible 3D Printed Macro Keypad

This project perfectly combines LEGO toys and keyboards to create a fun and practical three-key macro keypad. This keypad is made using 3D printing technology and is compatible with LEGO bricks. Moreover, it can secure the key switches without the need for a PCB (printed circuit board). Even more interesting, this project plans to use LEGO bricks as keycaps, by 3D printing a small adapter to connect the key switch stems to the bottom of the LEGO bricks. This creatively designed macro keypad is aimed at special needs, such as custom keyboards for people with disabilities, showcasing the charm of personalized and creative design.
