      Also on Twitter https://twitter.com/ThereminHero/status/1189721638419472384   The Goal Back in September I set out to build an LED cube made out of LED matrix panels. What I eventually ended up with is a battery powered / raspberry pi driven interactive cube, able to (among other things) play emulated NES and gameboy games while dealing with all the intricacies of wrapping a 2D game around the outside of a cube. Oh, and I threw in a lazy susan to make single playe ...
For halloween this year, I made two pairs of robotic DEAL WITH IT glasses. It uses a continuous micro servo on a 3D-printed linear actuator mount that I designed. I documented the whole project here, in a new channel called I WANT TO MAKE:   ...

Crabby Skullduggery

Posted by dougw Top Member Oct 31, 2019
I have been having a devil of a time trying to design and build an animated head for my animated crab chassis. My CAD software refused to make stl files of some of the parts, my slicer refused to properly slice some of the parts into a 3D print file, my big printer couldn't get a bad roll of PLA to print properly - it just wouldn't stick to itself. I printed off 14 parts successfully with white PLA but the big orange prints just kept failing. With Halloween fast approaching, I decided to change ...
Built using some scrap acrylic, blue book-covering, a scrap outdoor gas heater from the neighbour's throw-out, 2 range hood exhaust fan units from the junk pile of the local kitchen renovation business, some thrown out plumbing tubing from the junk pile of a building site and 8 takeaway bowls sprayed yellow, a shoebox and carton tubes from some posters sprayed red, red tubing from a broken vacuum cleaner someone threw out, parts from a broken pedestal fan someone threw out. Plus a lot of hours o ...
In most good horror movies there is a mad scientist (or mad engineer?) who needs to turn on his equipment for bringing a monster to life or other such thing. Typically there are big sparks as the switch makes contact as it does not have suitable suppression circuitry. I loved the idea of having such a switch but did not fancy having live electricity exposed to the users and real sparks are fun but also not that safe.   So I built my own knife switch. The first step was to model it in CA ...
For the past few years I have been building Animatronics controller boards for a client that builds really cool skulls (https://www.halloweenskulls.com/ ).  This client had posted a job, to replace an existing controller board with a lower cost product.  This has been a really fun project that continues to grow.   The three boards (from left to right) are as follows:   First Generation - 12 servo channels, 3 dimming LED channels (with common strobing channel), jumpers for ...

Scaredy Ghost

Posted by cozytom Oct 23, 2019
The Scaredy Ghost is designed to be scared by the spooky trick or treaters.     The arms are open to look like a normal ghost. When the scary trick or treater gets close, the ghost covers it's eyes because it is scared.   It uses a PIR sensor to detect the trick or treater, fed into an Arduino nano. There are two servos, one in each arm to open and close the arms. When the closed up ghost detects no motion, it will carefully open one arm to "look" if the trick or treater i ...
https://www.youtube.com/watch?v=UNyW8ooY1g8     The robot helmet/mask is made of common parts found at a hardware store....a cheap grinder faceshield, a bucket, and cardboard. The electronic parts are hobby store type parts,: an Arduino Nano, WS2812 strips, a LipO battery, 2 gearmotors, 2 DC buck power supplies., a pushbutton.  The type of scanning LED eyes on the robot are selected by pushbutton: cylon red, cylon blue, cylon green on white, police lights mode, flux capacitor ...
current revision video https://youtu.be/t-4IWkrXu9E   Protect the Universe with an Arduino Nano, qty 84 WS2812 NeoPixel LEDs, a DFPlayer module, and recycled household junk. The repulsor is powered with an 800mAHr LiPO battery. Always fuse the main circuit, and branch protect multiple module projects for ease of troubleshooting later.   A 15W audio amp and a repurposed iHome player (only reused the enclosure and speakers) adds some kick to the sound effects. ...
Inspired by the Indian Jones film "The Temple of Doom", I teamed up with "The Kuriologist" to make a skull bowl with jewelled eyes. The electronics are pretty simple. The "brain" is an Adafruit Gemma, some LEDs and a piece of audio wire screening to act as a sensor for the capacitive touch sensors.   The skull was made from scrunched up tape rolls, newspaper boxes and paper mache, the gemma was housed in a small cardboard box. The Kuriologist based the design on an ape skull and covered ...

The Eyes Have it

Posted by adamsoileau1 Oct 17, 2019
  This project took me a few weeks to complete mostly because of the minor learning curve for the IR transmitter and receiver on an Arduino. I used three IR sensors to track where a object was and then turned the two micro servos (with eyes attached) in that direction. I need to add that in the video, I accidentally referred to the batteries as lithium-Ion batteries when really they were lithium-polymer batteries.   I completed this using:   Arduino MKR ZERO Arduino MKR ZERO ...

Dark ride

Posted by lschmidt Oct 17, 2019
I created this dark ride for my son's halloween party and is based his ideas and ideas from other places on the internet.  It utilizes multiple Arduinos to trigger jump props including car horn/lights.  The track is made from 1/4" OSB plywood and 1" PEX tubing for the car to follow.  The PEX is very flexible and worked very well for the curves.  As the car goes around the track, it goes through multiple areas separated by black sheet plastic.  It was the easiest way to c ...
Hello, i want to take part to the challenge also with this video showing a pumpkin singing hologram. To make it i have used an iphone to record a small part of the video from youtube and converted in hologram with holapex app choosing the function to make video compressed, i have positioned at the center of the screen a hologram mini smartphone display and recodered it with an Android phone!   Enjoy it's a little black but remember it's scary!!!!!! ...
This project was done in a maker group a few years ago. My daughter & I resurrected it to share it with the wider audience and to develop STEM interests in kids. It contains an IR sensor, 2x LEDs and speaker connected to Arduino. When the sensor detects someone in the proximity, Arduino will blink LEDs and turn on a nasty audio sound. It is good enough to startle the little ghosts who come to get candy, but not to scare them.   Replicate the project with kids to teach them the basic pri ...
For this project I created two 2 cm x 8 cm PC boards each with 6 green LEDs.  I drive the LEDs with an Arduino so that the jack o'lantern eyes appear to move. ...
In my project, I convert my face into a glowing menacing ghoul.  I use yellow florescent face paint in an air brush to give my face an overall glow.  I then use more florescent paint to indicate veins and arteries.   I put on a custom made gorget that includes three ultraviolet LEDs in 3-D printed projectors bases.  These are wired to a AA battery holder built into the underside of the gorget.  The ultraviolet LED provide the illumination to make me glow in the dark. ...
Hello! I want to take part to this Halloween "Party" Challenge yep! With this design i have made of a Raspberry pi B4 Case similar to a Desktop Computer Black as Death and red as Vampires suching blood!!!! Remember this is Miles far away from Raspberry pi standards i made it by eyes and hands with a mouse.   Bye       Toolkitman     This is  a more Halloween like Version:   Made by hands is not perfection but you can have an idea!
