I printed danman's Halloween Crow at 98% to fit my PRUSA printer, added LED eyes and made a custom base for it.

Base and cover is printed in Hatchbox Wood Filled PLA

Pololu addressable LEDs for eyes

Controlled by an ATTiny85 powered by a 9V Battery
Arduino code ZIP file has links and URL information for parts programming etc.

FreeCAD native CAD Files and ATTiny85 / Arduino code attached.

I used a micro rocker switch - you'll have to modify the CAD file or STL for a switch of your choice. Since there are 1000's of switches out there I will ignore & delete requests for a specific switch.

This is just a base, you can get the crow from here:


Halloween Crow

Thanks so much for making your files available. Based upon my own experience, I think many would agree that "documenting" is harder, and perhaps less enjoyable, than designing the actual project. The bird printout was amazingly very smooth with NO support. But, I had some trouble removing it from my TAZ 5 PEI print bed (not your fault!). A problem to be worked with 3D printers is how to get the print to stick, but, no so much (somewhat a function of the size of the base of the print) that you destroy the PEI upon removal, which I did to some extent.

I wasn't aware of the LEDs that you actually used although I regularly use the WS2801 bulbs for my outdoor displays. They can be cut apart. Polulo was out of the LEDs else I would have ordered some for possible future use. If using just a few, like you did, interconnection is not that hard. I often use a dozen or so and I would go crazy if I had to interconnect them all.

Somewhere, someone, and I'll have to find it again, used this design to also make the head movable via a servo motor. I can do servos and would like to use both the eye changing and the servo drive AND add a motion detection sensor (relatively easy). The idea would be to "swivel" the head if someone approaches or swivel every "X" seconds just for affect.

Afterthought engineering is always easier than coming up with the original design. So, thanks for doing that.

Hi. Did you by chance ever stumble across the page that talked about someone used a servo to turn the head? I'm considering doing that this year, but why reinvent the wheel if someone else has already done it. :-)

I did a quick Google search, and this turned up, which I thought was interesting :


This is really a work of art (doing it out of paper!). Very impressive. I also like how the tail moves as well.


Of course, as soon as I posted the previous message, I came across this :


The trick is getting the head to swivel and getting the beak to open & close...

Very cool on both links!!
Thank you for sharing - maybe mine will need a few upgrades by this Halloween??

You are welcome!
I too thought about a servo for the head. I ran out of time before last Halloween and it would have been more mechanically involved than I had time to complete.
If you get it working - please be sure to post!
