Unless you have an incredibly well-stocked parts bin, it’s probably too late to build these spooky animated eyes to scare off the neighborhood kiddies this year. But next year…
It’s pretty clear that Halloween decorating has gone over the top recently. It may not be as extreme as some Christmas displays, but plenty of folks like to up the scare-factor, and [wermy] seems to number himself among those with the spirit of the season. Like Christmas lights, these eyes are deployed as a string, but rather than just blink lights, they blink creepy eyes from various kinds of creatures. The eyes are displayed on individual backlit TFT-LCD displays housed in 3D-printed enclosures. Two pairs of eyes can be driven by the SPI interface of one ItsyBitsy M0 Express; driving more displays works, but the frame rate drops to an unacceptable level if you stretch it too far. Strung together on scraps of black ethernet cable, the peepers can live in the shrubs next to the front door or lining the walk, and with surprisingly modest power needs, you’ll get a full night of frights from a USB battery bank.
We like the look of these, and maybe we’ll do something about it next year. If you’re still in the mood to scare and don’t have the time for animated eyes this year, try these simple Arduino blinky eyes for a quick hit.
Thanks to [baldpower] for the treat. No tricks.
