Picture of Miniature Revolving Solar System

I am not sure exactly where this idea came from. It started with a hollowed out light bulb that I had lying around and thinking that it would be neat to put a miniature solar system model inside.  Then I thought it would be even better if it actually moved. 

I became inspired when came across some images of orreries.  Orreries are mechanical planetary models that revolve at relative speeds using gears. Unfortunately in my own model the planets revolve at the same speed, but I designed it with fake gears and a plate indicating months, seasons and astrology glyphs to resemble a real orrery.

Step 1: What you will need

Materials:
  • Light weight clay
  • Lightbulb
  • Small clock
  • Brass wire
  • Bamboo skewer
  • Hard drive platter
  • Stand
Tools:
  • Glue: PVA, Super Glue, and hot glue
  • Printer and paper
  • Needle nose pliers
  • Sharpie pens, gold and copper model paint, nail polish

Step 2: Make your planets

I measured the diameter of my light bulb, as you can see I used a globe sphere which is rounder than your average bulb.  I determined how large I could make the planets and how far apart to space them. I cut eight pieces of wire making sure that they were long enough to wrap around the skewer.  I then bent up one end for placing the planet on.

Hey man !! can u tell me how do you balanced the planets with bamboo skewer

The clay I used to make the planets were really lightweight (http://www.amazon.com/Activa-Premier-Lightweight-Stone-28-Ounce/dp/B002VR0C26). I just spaced the planets out somewhat evenly around the centre and they were okay.

Do you consider Pluto a plantet, well I do
ChrysN (author)  J-Five1 year ago
Thanks! They are calling it a dwarf planet now, though I was tempted to include it in my solar system.

Hey congratulations on being a finalist in the hack it contest! Good luck to you! (I really do adore this, I am pulling for you, not that I have any power...lol)

Love it! And, as already said in the comments, it would be great to expand this with different rotational speeds and some moons... Or make one of an imaginary solar system, with freaky little planets and a double star sun :-)
ChrysN (author)  ynze1 year ago
Interesting idea making imaginary solar systems or maybe making one from the Star Wars universe or other fictional solar systems. I'm sure you'd be able to find star maps of the Star Wars one.

P.S. I voted "winner"

Thanks you! I made the paper with the months and season on my computer (my handwriting is not very neat).
Astounding! A real keeper! Perhaps I've missed this...did you free hand draw the summer /autum... paper?
I am in love with this, I would love to have it on my desk! Time for me to raid my husbands tools I believe.

Love it! I broke my light bulb so I will just have to wait until the next one burns out to try again...

I found hollowing out a light bulb to be the hardest part. Not to mention dangerous too, I got a few scratches from that.

This would be a great addition to the Mad Scientist lab, desk.... :) Good job!
ChrysN (author)  BluesBayou1 year ago
Yes, it would! Thanks.

OK, so I like corny puns :)

Great project - I like the concept of it being in a glass globe.

I wonder if drilling small holes in the skewer and inserting/gluing the free end of the wire-holding-planet into the holes would work easier than trying to wrap the wire tightly?

I also wonder if painted beads of the "right" sizes might work well for planets (with painted highlights).

Amazing concept and I really like the add on gears and other embellishments.

ChrysN (author)  lbrewer421 year ago
Thanks, the beads are a good idea, though I was worried that they might be a bit heavy, the clay I used is really light.
This makes sense!

Wow! Sort of disappointing. I thought the planets actually moved correctly like an Orrery. It is doable, inside the bulb, which is great BTW. Making it work would be non-trivial, but the gears would be for real. 

Concentric shafts is the key and construction not unlike a ship in a bottle.
ChrysN (author)  Exocetid1 year ago
Yes, that's why I didn't call it a real orrery, I don't have any experience making gears, I guess you can design it on a computer and print it out in 3d or cut them on a laser cutter.

Wicked is right.
This is great! I love orreries, they always held my interest when I was in school.

I know at this scale it would be incredibly difficult, but if the glass bulb was a little larger there may be room to put the inner planets on the seconds dial with the outer planets on the hour dial, giving to different rotational speeds.
ChrysN (author)  mikeasaurus1 year ago
I think if you make it without the light bulb you could do this easily, you could probably put Jupiter and Saturn on the minute hand and Uranus and Neptune on the hour hand. Most orreries models aren't under glass anyway.
