It is time for our Halloween project round-up! I wanted to give a mention to every project submitted so we can all appreciate everyone's hard work.
There have been so many fantastic submissions this year, a big thank you to everyone who shared their spooky projects, Halloween plans, and took part in the seasonal celebrations. If you have not yet seen every project, then this is your chance! Click through and take a look.
Halloween Motion-Activated Scare System
veluv01 created an automated scare system for Halloween. They used an ESP32-CAM compact camera module to stream video to a Raspberry Pi. The Raspberry Pi then used computer vision to detect victims and triggers terrifying sounds from a hidden Bluetooth speaker for a perfectly timed fright.
Ghost Projector
misaz created a Halloween trick for anyone entering a dark room using a microcontroller, motion, 4 addressable RGB LEDs, a LEGO brick box on a slight angle, and a sheet of paper. When it detects movement, the motion sensor triggers the four LEDs inside the LEGO box which take it in turn to light up and shine through the ghost pattern cut in the sheet of paper. This creates the illusion of the ghost moving, despite the project box staying in a fixed position. A great project with a great use of kit.
Haunting Eyes
meera_hussien added an ESP32-S3 microcontroller and two round GC9A01A displays to a 3D-printed skull – with a gesture sensor hidden in the nose – to create a spooky head with scary red eyes that follow movement and reacts with eerie sound effects.
The Vessel
Using an ESP32-S3 microcontroller, a 3.2-inch ILI9341 TFT display, and an HC-SR04 ultrasonic motion sensor, Hacktech created a motion-triggered haunted box which reacts to trick-or-treaters with warning messages, fog releasing from hidden vents, eerie noises, a servo-driven lid that shakes and bangs, plus suitably spooky lighting effects.
Automated Trick-or-Treating
foxbat built a ‘trick or treat’ machine with lights and sounds that trick-or-treaters can use to press play, choose whether they want a trick or a treat, and then either candy is dispensed or they receive a startling (but not lawsuit-inducing) trick. Check out this submission for its photos, videos, diagrams, plus an 18-page write-up attached covering all the details of the project.
Whispers of the Web
Donatus created a browser-based psychological horror experience, with whispers made to sound like they are coming from different directions and the player is prompted to type what they hear.
Haunted Mailbox
dougw made a mailbox look like it was haunted by adding high resolution TFT displays showing animated eyes that look around. A lawn art black cat was given red LED eyes that turned on when a PIR sensor detected someone approaching. Check out the full write-up for a video, a glowing pumpkin and @dougw’s work party costume.
Screaming Halloween Scary Mask
rsc added round Seeed Studio XIAO TFT displays with spooky eyes to a very scary mask. A motion sensor from a night light and a Raspberry Pi triggers a scary witch’s laugh which is well worth hearing, super spooky!
Halloween Crabby Crabapple Tree
With a build featuring an Arduino Nano, PIR sensor, ISD1820 voice recorder module, and LM386 audio amp, robogary brought a crabapple tree to life. The tree has plenty of attitude as it tells passersby and trick-or-treaters to stop treading on its roots.
Basement Dragons
Using four computer monitors, 3B+ Raspberry Pi’s, and dark garbage bags, colporteur was able to have two pairs of huge animated eyes peer out of his basement windows. Here be dragons!
SoulCage
vishalsoniindia created a wearable pendant which – using a Waveshare ESP32-S3 Round Display and a 3D-printed case – appears to have an animated soul trapped inside it and trying to escape. Their write-up contains plenty of detail and links to all the components for anyone inspired to make one themselves.
The Third Eye
me_Cris created a mysterious, animated eye using an 8x8 LED matrix, a head lamp housing, and an ATtiny85 microcontroller. The eye really comes to life in the dark and you can watch the eye look around its surroundings in photos and a video.
Great projects all round! With our round-up complete, it only remains for me to announce the winners on November 16th, so there is not long to wait now :)
If there are any updates on your project and you would like me to add anything to the description above, then just let me know.
