Dome

Very nice!.

At the moment you need to put a link to the video - Google changed something and the plug-in is not working correctly - working on fixing this.

Thanks! I edited the post putting just the link as you suggested.

I really like the design of your lift system, especially using the center of the dome as the mount point.

Maybe you could try putting a second attach point on the jack screw adjacent to the servo to keep your lift perpendicular. Or a second set of guides on the rails. That way it would not sag backwards. I guess I want you to work out the bugs so I can use your design in my droid (hehe). Excellent work!

Oh, where did you get the lens for the periscope?

I tried several different solutions, but this is the only one that really satisfied me. My only concern is if it will be strong enough when attached to the top of the dome to keep the weight of all the parts...

I solved by adding a couple of contraints for every bar. Sag is now almost disappeared from the life scanner. I still have to test the periscope as it's much heavier...

This is a screenshot from Blender (the only software I use):

The constraints I'm talking of are the red parts.

I designed the lenses by myself and printed them using transparent abs. Of course the result is just translucent and not transparent, but this is exactly the effect I searched for. You can find them here: https://www.thingiverse.com/thing:2834270

Well the lenses looks great in your photo. Also, are you using a continuous rotation servo for the lift? I want to try and rig a GoPro or similar camera to go in the periscope, I am not sure I can pull this off and make the camera hidden but functional. I think it would make an awesome "candid camera." (If anyone is old enough to remember that TV show). I think it would be better than behind the radar eye as the periscopes movement will draw attention and people will be looking right at it.

Yes, I'm using the FS90R micro servo. They are quite good and small and can be driven like any other servo (just one pin from the controller instead of two of a standard motor).

GoPro are quite light (I also have one Wink ), so it could work. Putting it behind the radar eye would be a nice option, but you should have a good eye for that. Using domes from cheap fake surveillance cameras for example would be a bad idea as they have tons of defects that will degrade the acquisition (I tried it using the small camera from a Raspberry Pi). Also it should be a dark lens or the GoPro will be seen too easily and also the R2 style would also be compromised (this last is just my point of view)...

Looks excellent to me.

For the radar eye, I got this from Amazon.com.  It fits perfectly and looks great.  I painted mine black on the back.

At last I tried my lift system with the periscope. Not completely stable, but of course it's still to be fixed to the dome. I just wished to check if the servo has enough power to also lift the periscope and it seems to work...



You can also see the clips I'm using to keep the guides from bending too much (four red clips and four white clips). They work fine for the life scanner, but give just small help for the periscope, but that's ok. Maybe in the future I could add some more clip to the periscope guides to make them more rigid...

Because of the weight of the periscope, this time I need to use the full speed of the servo to move it, when for the life scanner I went much slower.

You can find the models on thingiverse. Link is on my post fo models: https://www.3dprinteddroids.net/thread-195.html
