3D printed eyes for a new puppet

[@OakLaneCemetery]

That's so cool. I've been thinking of making the eyes in my witch move the next time I rebuild her head, but I'm just going to do a simple side to side animation that gets mechanically moved when the head turns. Less to figure out! lol

Well done. Best wishes for the summer.

[@intocoasters]

Thank you! Hope y'all are doing well too.

Very cool, but wow is that an elaborate way to do the servos! :) I have been working on a board with a couple of friends that is based on the "Jawduino" but controls a bunch more. It's basically an arduino nano and an mp3 player that will sync the jaw servo with anything that is on the mp3 SD card, it also operates 4 other servos to do random movements at different speeds and operates LEDs etc. Hopefully, I'll have a video of it up soon. I really love the look of that pumpkin head man!

Looks awesome. I like the new character. The Servos to potentiometer seems like a clunky way to do that, too bad there isn't a better way to interface the board. If it's PWM, could you charge a capacitor to build up a DC level... hmmm... maybe it's not as responsive. That's a tough one to think about, but I like the character

[@intocoasters]

Yes indeed it is clunky... and has a lag. But I am not any good at altering arduino code to read the LOR servo outputs instead of the joystick. My first attempt was to control the joystick directly with servos - that was a disaster. This iteration is much more compact and reliable. But I am sure it could be tighter with a direct connection between the LOR controller and the arduino uno. I just don't know what to rewrite to make it happen. And thank you! This guy has been a blast to build! I can't wait to show off the entire puppet when complete!

@@intocoasters don't all servos already have pots? I thought that's what made them servos and not just motors.

[@intocoasters]

@@ge2719 you are correct! The pot in the servo tells the motor when it has reached the target position. That's internal feedback for the motor itself. The pots outside, like in a joystick or a radio controler, those tell the servo motor what the target is. When you move the joystick you're turning a potentiometer to a certain position between 0 and 100% of its value (this will affect a PWM signal that is sent to the servo) The servo motor then moves to try to match that value. That's kind of an oversimplified version of how it works.

Wow. Looks great. Coming along nicely. Appreciate you sharing.

[@intocoasters]

​@@allthingscoolandcommon5161 Thank you very much! These kind of builds are always fun to share. I'm hoping this guy turns out like the vision I have of him in my head. Should be an amusing addition to the existing trio.

Where did you get the Pumpkin head from? I've been looking for one like that for a project

[@intocoasters]

@@cmpenney this was one half of a set from home Depot. I greatly modified one of the characters to work with the 3D printed eye mechanisms. www.homedepot.com/p/Home-Accents-Holiday-3-ft-Halloween-Animated-LED-Pumpkin-Twins-21PA36156/315534297
