Many states are uncertain how to handle trick-or-treat activities amid COVID this Halloween. But DIY-ers have plenty of good ideas!
The season of spookiness is almost here. But even after this year’s COVID-19 ridden Halloween activities are gone, these clever projects will still be around.
For now, though, all of these mostly do-it-yourself (DIY) projects are designed to either reduce the spread of the novel coronavirus or even destroy it. They will help ensure that this year’s October 31st activities do not become a super spreader event.

Ultrasonic Array Powers This Halloween Spirit Writer
https://hackaday.com/2021/10/12/ultrasonic-array-powers-this-halloween-spirit-writer/
The spooky season is upon us, and with it the race to come up with the geekiest way to scare the kids. Motion-activated jump-scare setups are always a crowd-pleaser, but kind of a cheap thrill in our opinion. So if you’re looking for something different for your Halloween scare-floor, you might consider “spirit writing” with ultrasound.
The idea that [Dan Beaven] has here is a variation on the ultrasonic levitation projects we’ve seen so many of over the last couple of years.

ESP32-Cam Makes A Dandy Motion Detector
https://hackaday.com/2021/10/23/esp32-cam-makes-a-dandy-motion-detector/
Halloween is right around the corner and just about every Halloween project needs some kind of motion sensor. Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation. You can see a video of the device and how it works below.
ESP32-CAM as a Directional Motion Sensor | Halloween Animatronic Fun!
https://www.youtube.com/watch?v=NIbiG6at01g
Today we explore the use of an ESP32-CAM (ESP32 with Camera) as a directional motion sensor. While motion sensing with an ESP32 has been available for some time, I take it to the next level using it in an animatronic Halloween project. The project uses only an ESP32-CAM as the entire motion detector and the microcontroller driving the stepper motors. The entire project is open source allowing you to use this in robotics or other projects where you need a cheap and easy motion sensor. This project is limited only by the visual range where many PIR and Ultrasonic sensors have a limited range. This works great for projects where you want to detect a cold object (not a living body) or objects far away. The base code uses a 10 degree range for its stepper movement but you can alter the code and the way the project works to fit your specific needs. I also cover how you can purchase an inexpensive IR Floodlight to enable the use of this at night or in low light situations. This worked great as a Halloween animatronic project where a spooky inflatable eye follows you around the yard.

Inside a water-ripple projector
https://www.youtube.com/watch?v=9A_REsWTznI
A look inside a typical tungsten lamp based water-ripple projector.
This is a very generic Chinese clone style unit that lacks proper optical efficiency.
It’s designed to operate with a high output 12V 100W narrow beam lamp, but the high output lamps like that have a very short lifespan of around 50 hours. Using a lower power lamp or long-life lamp results in a much longer run time between lamp changes, but at the cost of intensity.
Nowadays these projectors tend to use LED based light sources. The ripple mechanism remains very similar between larger units like this. Sometimes with a dichroic glass colour wheel that can operate independently or in conjunction with one of the ripple disks.
The visual effect that these units produce is very subtle and soothing. Like a reflection from a pool or the sea.
