Styrene R2-D2 dome hinge with servo

Servos! I have 90 degree servos. Not 180! With Arduino control i can get more range. But for easier setup i will use a servo tester, so it needs to be within the 90. By adjusting the offset of the servo from the hinge the section of servo range is easily adjusted to allow for the difference in the cog positions of the servos.
Really pleased with Mk2 proper. :) So much stronger, more solid and running well. Just need to make 3 more of these and then redo for the lowers and do 5 of them! It never ends. :D

Looks really good.

Hey I’m working on a project something like that maybe u can help me with it? Using a servo or dc motor.

Hi Brad, this looks really great. I'm wondering, how do you build these things? I want to build some things with servos but I'm not sure how to build parts. Is the hinge/arm made from ABS plastic? Do you use a laser cutter or 3d printer? How is the servo attached to the styrene?

[@I8U2Astromech]

It is 3mm styrene cut on a small CNC machine. Servo is stuck into a holder with servo tape. :)

Are you providing the stl files for printing 3D or selling them somewhere. I'm putting my dome together now and need hinges. I have a 3d printer and have printed a couple hinge designs and not happy so far.

[@I8U2Astromech]

Sorry dude, no files for these, lost them. :(

[@rknill1]

I would like to use your hinge design on my dome. Can you make your plans available?
Excellent work.

[@I8U2Astromech]

Sorry, i lost the drive with the files. Im going to redo them for the Hydro domes next. :)

[@rknill1]

Thanks for getting back to me. I will be waiting. I was not aware you can cut styrene on cnc. That would make an interesting video when do the next batch.

[@peten6445]

Great work!! Any spec for the club?

[@I8U2Astromech]

Thanks. I will share the plans when all installed and proven. :)

[@peten6445]

Brad,
Did you 3d print them?

[@I8U2Astromech]

No, these are CNC cut styrene. Check Astromech dot net, there are a few 3D designs now

[@CrisMadla]

What do you use to make the pivot joints, what do you to connect the links to the servo horn?

[@I8U2Astromech]

Just M3 hardware. Nothing fancy. :/

[@CrisMadla]

@@I8U2Astromech what's kind of thing do I search tho? I've been trying to find a part to youse for hours for my own project lol. It would be greatly appreciated.

[@I8U2Astromech]

Just bolts, nuts and washers, in M3 size. Not even a shoulder bolt. ;)

[@CrisMadla]

Brad Oakley oh ok thank you! I thought there was something you could buy haha. Cool mechanism btw!

[@I8U2Astromech]

There are lots, I didn't find the need for this set. For my carbon hinges I used bearings. ;)
