    Jun 16, 2012 - Budget R2-D2 (W.I.P.) #1

    Hey everyone!

    First off,.. everyone is so awesome on this site, I hesitated posting my build for a long time.

    This build is not meant to be screen accurate. I am having a Star Wars party at the end of July and got it in my head that a real life R2D2 would be awesome.

    I found a build on Instructables - Make, How To, and DIY and the R2 Foam Build from familyman on this forum.

    After a few weeks of research, I dove in.

    GOAL: 1:1 Scale R2D2 with spinning dome and sound.

    I've already been at it for several weeks,.. so... here are the pix.

    Remember,.. this is a BUDGET BUILD!!!

    So,.. I just moved into this place and had a ton of cardboard boxes. So thats what I started with. I also had some chicken wire and wrapped it so that the joint compound would have something to stick to.



    I decided to create his eye using the botom of a red plastic cup and some other things I had lying around.



    I wish I could have it alternate from Red to Blue,.. but oh well.

    Trying out eye placement and seeing if it'll work.



    Once I get the wiring figured out, I added a battery pack from an old digital camera I had that was broken.



    [/url]

    Looking back,... I should have put the eye lower,.. but I can't do anything about that now.

    I thought I'd have a hard time at the joints.... so I bought fiberglass joint tape and went to town on the joints.



    I figured I would make the dome removable, which meant I had to have an on/off switch on the dome for the eye. So I took apart an old light I had and used the switch.



    Once all the wiring and wire mesh was done,... Joint Compound time.
    Why did I use joint compound? Well,... cause its all I had in my garage. And since I'm on a major budget, thats what I used.

    First Attempt Fail:


    I ended up having to wrap the whole thing with the fiberglass tape.
    [/url]

    The tape kept popping up, so I used a blow dryer to soften it and have it stick to the wire mesh. Was actually surprised it worked.

    Second Attempt Win:




    After a few coats of joint compound,.. I came to the realization that the base was twisted. This was really bad because I decided I was going to try to make the dome spin.

    I ended up having to go buy some particle board and recut a base and attached it to the bottom.

    This made the dome a little longer, and unfortunately makes the eye seam a little higher.

    Here is where I am at the moment with the dome.





    And just today added the first coats of primer.



    I am currently working on the body and Legs and will post my progress on those next.

    My first few posts seemed to lose pics as well. Edit your post and add them back in.

    Success!!!!

    Well,.. first time post problem I guess!

    Here are some pictures of the body!

    I started off with the top base. I found a remote control car from the thrift store and used the motor. I know it doesn't seam strong enough, but I rigged up and it actually turns.

    [/url]

    I had an old broken plotter in my garage, so I took it apart and found some gears and stuff I could use.



    I had to go by some 1x1 wood pieces at Hobby Lobby and used those to frame the body.



    From the plotter,.. I took the spindle that the paper went on and used that as an axle support for the dome.



    The bottom base piece is so that my axle stays in place.



    I'm going to copy familyman's build on this site and do the body and legs in foam.



    Will post more on the legs in which I am currently working on.

    Ya it is! I went through two tubs of joint compound. I think I ended up doing 8 layers before I got it to where it is now. Its still not perfect, but I'm running out of time on this.

    This Friday I'm picking up more primer and some silver paint for the dome.

    Thank you so much everyone for the comments!

    Maybe I can get some help with a sound problem I am having.

    I bought this Remote Control MP3 Player for $15 on amazon.



    I hooked it up to my battery pack witch is running 5 AA batteries. The MP3 player requires 5v, so its fine.

    I get sound out of it, but it is so low you can barely hear it. I think I need an amp.

    I found this from the same place I got the MP3 player,...

    Dayton Audio DTA-2 Class T Digital Audio Amplifier Module 300-385

    Has anyone used anything like this?

    Usually if its so low you can't hear it, it means a speaker wire is crossed. You might want to double check your wires to make sure everything his hooked up 100% right. I've used one of those before, but never for an R2 Build. They are quiet, but not super quiet. Its as loud as say a small ipod dock...

    Edit: I have used the sound board, not needed an amp as of yet. Its not the loudest thing ever.

    I hear it,.. but it sounds more like its for a headphone as opposed to a speaker.

    There are only 3 wires for the speakers. Left, Right and ground.



    Could it be my speaker is to big? I took apart an old boom box and took the speaker out of it.

    I just got this response from the Parts Express tech advisor,....

    "The output is at best a headphone level, which is not really enough to drive a speaker. I would say a small amplifier like one of the board amps would solve your problem. "


    Looks like I'm ordering the amp on Friday!

    Sweet!

    That might be good for me. And I'll save a few bucks on shipping!2 cents

    I just checked online and my local RS has one in stock. I'll go by there this week and check it out.

    Thought I would show you how the motor works.

    I need to add some axle grease to make it quieter.

    I'll go check them out. I sized the frame for the EVA foam I am going to use, but if I can wrap the foam with the plastic board, maybe that will be easier to finish.

    Or I scrap the foam alltogether and just use the plastic boards. I'll look into it.

    I don't ever remember which lens is considered the "eye" on R2, but if this one you mention is the one getting the blue box and lens over it I think it looks fine.

    If instead this is the round light that is next to the protruding "tube" lens then sure, too high, but if it's high enough to bug you I'll bet you can fix it somewhat easily - back the light off toward the inside a little, angle it slightly downward and cut a new hole/patch the old one - since the "face" of the light is frosted anyhow it shouldn't matter if the light is a little bit farther away from the surface.
