I made several other simple props. One of which
@stienman helped me out with over at stack exchange. This mess is 8 pairs of lights designed to trigger in slow sequence and then fade out. Partly a turn signal circuit design and partly stuff I made up together myself. Part count got kind of high for something so simple but what can you do. There's a 555, a 741, an optocoupler (the fading needs higher V than the 555 can handle, and I couldn't put in another transistor without saturating the caps and losing the fade effect), a regulator, and a homemade IR proximity detector (which uses the 741 as a comparator--thanks Instructables). It's staying on a breadboard until after Halloween, because I want all those parts back.
Anyway, I'll be distributing them through bushes and ivy as eyes that light up when triggered.
On the plus side, between all these projects, I finally found a use for 150' of telephone wire I've been carting through 3 moves now...
