Let's blink an LED using the 555 timer ic. You can do all sorts of things with this chip but we'll be focusing on one of the easier projects to get started. By the end of the meetup you should have a working circuit that blinks an LED. You can use this as spooky ghost eyes, or inside a pumpkin. You can look further into the 555 IC and build alternating blinking eyes! After halloween? Use it as a fake car security system ;)

Lighting structure is separate from it's 'costume'. The lightning is then compatible with any/all festivities and we can encourage the community to decorate/make costumes for them.
The lighting system itself could be made 'intelligent'. They could sparkle as people pass by. Or if it were for halloween, they could play a 'spooky noise' as people pass by. They could be networked together, to put on simple, but coordinated light shows. The color and intensity of the light could play a role too. Think the blue gas light in Milwaukee... Blue on colder nights, Orange when it's warmer.
Ok, here is a thought that's getting out of control... Allow people to interact with the lights via the web (their phones). Each light could have a little 'dance' pattern... Or again, if it's halloween you could allow people to control what it says... as their friends walk by, they could scare them, or play something funny. Oh(!) Valentines day could get really cute with this idea.
Not thinking about the "costume" yet, the lighting

Simple HOWTO to get 5 digit year support in WordPress.
This is a cosmetic tweak only, meaning WordPress, your database and system in general will not recognize the 5 digit year as a valid year. This is fine however. With this tweak we get it where it counts; Your URLS will cite 5 digit years and your template can be adjusted to also display them. It displays where your users will see it and that will get them thinking.
-
Go to your WordPress admin panel. Under Settings -> Permalinks select
Custom Structureand add your padded zero:/0%year%/%monthnum%/%day%/%postname%/ -
Since your URL structure just changed, add rewrites for URLs citing 4 digit years (legacy support). Under Nginx add:
