Affordable ESP32 CYD Touchscreen: A Fun Lockbox for Under $30
In the realm of technology, innovation often comes with a hefty price tag. However, a recent project by Chad Kapper, as reported by Hackaday, demonstrates that you can create a fun, interactive, and affordable lockbox using an ESP32 CYD touchscreen. This lockbox, perfect for escape room props or tabletop role-playing games (TTRPG), costs less than $30, making it an attractive option for creators on a budget.
The ESP32 CYD Touchscreen: An Imperfect Gem
The ESP32 CYD touchscreen, also known as the "Cheap Yellow Display," is a low-cost development board that comes with a 240x320 touchscreen, WiFi, a speaker output, and various other features. Despite its incomplete documentation and minor imperfections, the CYD is a popular choice among makers due to its low cost, functionality, and creative potential.
Creating a Numpad and Beyond
For this project, Chad Kapper used the ESP32 CYD touchscreen to create a functional lockbox for an escape room puzzle. The full-screen touch controls allowed for the easy creation of a numpad, enabling the design of an escape room that involves finding a four-digit code to access its contents. However, the touchscreen's versatility allows for much more creativity, as users can create codes based on shapes or design simple sliding tile puzzles to open the chest.
A Cost-Effective Solution for Creators in North East India
This affordable ESP32 project offers an exciting opportunity for creators in North East India who are looking to add an interactive element to their escape room props or TTRPG adventures without breaking the bank. The region's growing interest in technology and DIY projects makes this project particularly relevant, as it provides an accessible and cost-effective solution for local creators.
Looking Forward: The Future of Affordable DIY Projects
The ESP32 CYD touchscreen project showcases the potential of low-cost technology in creating engaging, interactive experiences. As more affordable and versatile development boards become available, we can expect to see an increase in creative DIY projects that cater to a wider audience, including those in North East India.
