So I have been playing around with a some used PIRs and I think I have learned a few things but I just want to confirm. I am working with 12V PIRs and have 12V actuators or 12 V LEDs hooked to them. First I noticed if I tried to directly hook the PIR to the actuator that the PIR triggers over...

Hey all, Kinda looking/searching into more animatronic props lately (building myself) and wanna get more into electrical and motors, etc. I created this prop this year, kinda like tombstone, built outta foam and wood. Maybe weights 20lbs or so. I was thinking of raising it up and down. So...

Here is my take on the monster in a box. The box use to be a bedroom 3 draw chest. Completely self contained. Controlled by a Four banger setup, powered by a 12v battery and a 9v for the Uno R3. Actuator is surprisingly powerful for it's size and price (£1.85)...

HOLY COW This linear actuator is so loud. Are they all like this or did I just get a unusually and ridiculously loud one?? As well I attached it to a picovolt and it goes soooo sloooow. I cannot control the speed at all. It came with it's own controller but not a power source so I used my...

From linear ball bearings, to actuators, to pinion and gear racks and more, Kyle and Jason help explain various methods for driving linear motion and when and why each one would be ideal for your build. Below are some additional helpful videos we've released related to linear motion. Stay...

Long time lurker, this is my first post. Just a few pics from this years yards display. https://photos.google.com/share/AF1QipNwCw7TkDj0JyU7LX76Gg0gPFJVaBStJZdDjQGzCVmB89T2Nnpf9GeD3QbjKu6uXQ/photo/AF1QipPuef8EUtJOKDRsfb8VKvTHdLSkELmIhNYIpa-S?key=ckRnWHBJbkpEODNuXzVIaHRVaVI3ZHg0OGJrZVRR The...

I'm curious if anyone has done a chair that rocks itself (with or without something sitting in it...)? I know this must be as ease as attaching an actuator of some kind to the back of a rocker, but has anyone done it? Would like to do something simple/cheap/quick for this year.

Hi everyone, First off, thank you so much for the wealth of information on this forum. So helpful. This is my first post and this is my first try at an actual, custom built prop. I had no idea what I was doing going into this but I knew what I wanted. I had to learn about actuators, Arduinos...

I must be an electrical idiot. So I want to activate the actuator using a wall wart and a prop controller. When I connect the wall wart power supply to the actuator it acuates but it is humming and it is easier to push down with my thumb than when I have it hooked to the battery pack. It is a...

I have an Ani Motion Frankenstein mask and would like to automate the jaw moving up and down. Has anybody done this before? I suppose I could put a small pneumatic cylinder in the mouth but would rather have it cycle it up and down with a motor (actuator?) without having to be particularly...

This is a very inexpensive project and a great intro to electronics. This build is completely based off of Bigant's Monster in a Box which he posted here. I used all the same electronics but instead of an opening box I've got a quivering corpse. Speaking of the corpse, the pvc 'skeleton'...
