Description:

markdown

Intended to be an entertaining overview of challenges faced and lessons learned working on my first big maker project. Using code snippets, pictures and short demos, I will discuss problems overcome while developing new features and integrating new devices into my humble animated sign, which includes lights along with rhythmic and melodic components. I promise not to dance; no one wants to see that.

The intended audience is anyone interested in maker projects. I will also be touching on introductory-level topics in type hinting; the standard library modules abc, dataclasses, signal, and threading; and the 3rd-party modules aiohttp, gpiozero, and requests.

`Note on Photosensitivity:`  
Based on [this epilepsy.com article](https://www.epilepsy.com/stories/shedding-light-photosensitivity-one-epilepsys-most-complex-conditions), this presentation should be safe for any photosensitive audience member. I will include this information in a slide at the beginning of the presentation, and give anyone in the audience the chance to leave or ask questions before proceeding.

* The sign project uses standard 60 watt incandescent bulbs, which are not capable of producing a strobe effect.
* For further safety, during the presentation, bulbs will not cycle on and off more than 3 times per second.
* Additionally, the room’s lighting will not be darkened more than usual for a standard presentation.
