Digital Pumpkin Carving
S. J. Zhang
When we were tasked to doing something fun for Halloween, we didn’t want to do another ghost with a servo motor inside. After a few meetings, our idea settled as a pumpkin drawing competition, and maybe Hey! we can later use all the data to teach a machine how to draw pumpkins.
We found the ideal 32 x 32 LED matrix for our purpose, but without a data sheet. However we managed to find a few other people on the internet that worked on similar projects and followed their processes and recommendations on the power and set up.
After we got the matrix to map what we have on screen, we started making a simple pumpkin shell for the matrix. We wanted a nice rounded corner on the exterior so we tapped the corner LEDs to prevent lights shinning through.
The last thing before setting it up at the Halloween party was giving it a nice interface. My partner Lydia was very keen on capturing my css moment.
