I only decided to do Halloween 2015 about half way through October.
Some items were bits I bought in 2014 when they went on sale after Halloween.
The original white LEDs were replaced with colour changing types.
I joined them together, added a resistor and zener diode for 12V operation.
A couple of people asked where I bought them from.
They now run from 12V and a central power supply.
A few bits of recycled timber (pallets) made a quick frame.
The headstone was from a Big W pack.
Some dead tree leaves filled up the frame.
One of my cheap LED spotlights highlights the scene.
I also used a couple of 10W RGB floods under the trees set to static colours.
A car door lock actuator bumps the lid randomly when someone walks past.
The chains rattle with the lid banging.
A string of RGB LED modules were thrown inside to change colour when it activates.
I ran out of time to add some stenciled text to it.
Next year I hope to add some monster sounds.
It’s mounted on a spike in the garden just before the crate.
I’ll describe how to make this from eBay parts in due course.
The skeleton dog was from an eBay seller.
I removed the battery / speaker box from his head and added a cable for the eye LEDs.
A control board now powers the original electronics and interfaces to a sensor.
The speaker output of the original board was wired to a larger speaker that sits at the rear of the box.
A future version of this prop may see the jaw animated with a small servo.
This sensor has a limited range (~ 80cm) so I had to position it close to the visitor’s path.
The foam didn’t expand very well at all so I wiped most of it off.
So I went up to the park at the end of my street and grabbed some sticks.
I wanted to add green LEDs under the water but ran out of time on the day.
Next year I’ll add a little more background illumination, especially near the patio step.
