DDL: A Maker project with Mike McCaffrey

# October 2026: A Maker project with Mike McCaffrey

We have a special guest this month from the far north (Michigan): Mike McCaffrey!
Mike wowed the attendees at PyOhio 2026 with his Maker project, a beautifully-crafted display of dynamic lights, much wiring, single-board computers, and of course Python. He’s continued working on the project and is bringing it to us so we can experience it personally, and learn how he did it. He promises

> A hopefully entertaining overview of challenges faced and lessons learned during the first two years working on my first big maker project. With code snippets, photos and short demos, discuss problems overcome while developing new features and integrating new devices into my humble animated sign, which now includes color LED lights, new sound and input devices, various interactivity, and some surprises.

DDL is dedicated to discussion of technology and techniques related to dynamic programming languages: Python, Perl, Ruby, PHP, JavaScript, and sometimes something more exotic! These languages are fun and easy to get started with, yet powerful enough for all manner of professional use, and our members span the full range of experience with them.

We always leave time for general conversation and questions. Come try one of the most interactive groups around!

The Dayton Dynamic Languages User Group meets the 2nd Wednesday of each month from 7 to 9 PM, online and at Dayton's Innovation Hub (part of the renovated Arcade conmples). Use the General voice channel at discord.gg/9SgTh3T

We are a Special Interest Group (SIG) of the Dayton Microcomputer Association. http://d8ndl.org
