Hi All.

Ever had an idea pop into your head and you can't stop thinking about it?  Well my idea was to have a tiny plane spinning inside a light bulb, activated by a sensor!  Yes I know - not much of an idea but there it is. 

First I prowled the internet trying to find the right type of sensor and I came across the PIR sensor.  These are really ingenious and work by sensing infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted.

I purchased a couple from Ebay and started to try and hack them by using a relay.  After much frustration I decided to give this up and try another avenue.  I found a heap of articles using arduino but I wanted to keep it simple.  In the end I decided to use a 8 LED Light PIR Motion Sensor .  The sensor had everything I needed to enable me to hack away with ease.

So here's my idea come to life - kind of.  After much breaking of light bulbs I finally managed to complete the project.

Hope you Enjoy.

Step 1: Things to get

Parts List

1. 3v geared motor. You can get these here. this one has 15 revolutions every minute - nice and slow.

2. 2 X 5mm LED's. I used yellow ones.  They can be purchased here on Ebay

3. Plastic diffusers for the LED's.  I used some from a set of solar LED's.  You don't have to do this but it makes the LED light softer.

4. Small peice of dowel wood.

5. PIR sensor light - you can buy these here

6.  PIR sensor (just the sensor).  Buy these here

7. Copper wire - I used 2 types, 1 thin and 1 a little thicker.  These can be purchased from your local hobby shop.

8. various coloured wire

9. Various brass attachments.  i purchased these from my loacl hardware store. 

10. Samll square peice of wood for base

11. Battery holders.  The voltage I used was 7.5v so I used a 3v and a 4.5v battery holder.  These can be purchased from your local electronic shop

12. Tiny plane! I used this one


1. Phillips head screwdriver

2. Hot glue

3. Soldering iron

4. Dremmel

5. Drill

6.  Pliers

this is by far my favorite ible
Thanks! I was thinking of re-visiting this ible' again soon to make a different version of it.
<p>mega !</p>
Nice,it gives me some other good ideas.
Very cool!
Thanks dude
Thanks dude
Good work. I love the simplicity and the overall look.
Hello! Nice project! I was wondering why you cut off the light's PIR sensor only to add one back on? Was it because the you wanted to be able to move it around?
Howdy<br>You don't have to do this step if you don't want to - it all depends on where you want the sensor. I did it so I could move the pir sensor to where I wanted it.
This is a very cool lamp!! All your links to the materials is wonderful. Thank you for posting! <br>
This is one of the coolest little hacks I've seen, nice work!
What an astoundingly simple and excellent flying model lamp. Beautiful. Thanks for showing us and may I ask what is that superb music that played when the video of the lamp was being shown?
Thanks. <br>The song is: &quot;Music For A Found Harmonium&quot; from the Cafe Del Mar The Best Of album
I think this is very cool project. I have small grandchildren so in the next year or so, I will start making these for Christmas &quot;stocking stuffers&quot; for them. Should be an instant hit. Thanks so much for freely sharing this with me!
Anytime - glad you liked it
This is a great idea, really very neat looking, perfect for a cabinet of curiosities. <br> <br>I'd like to do something similar, except try to use some planetary gears to create our solar system, with the LED in the center as the sun.
Love the idea of sticking a solar system in one. If you get around to making one post a picture so i can check it out!
This is so cool, I love it!
Cheers - love your work too! <br>Good luck in the light and lamp contest : )
Thanks, good luck to you too!
Awesome idea. I suspect you could sell a tonne of these, you should go into production;) <br>
Very cool honestly! <br>Only thing I have to say, is that I hope people use old burnt out light bulbs to do this project instead of ruining perfectly good ones.
especially since there Edison bulbs and those may not be around for much longer.
Really cute, I like it! I too was reminded of the old Paramount intro. <br> <br>I assume the sensor isn't binary on/off? It would be a even slicker if the brightness/speed was proportional to the distance of the viewer. I'm definitely adding this one to my 'potential projects' list.
Arduino + ultrasonic sensor will do that in a jiffy. And won't cost you an arm and a leg, just the arm. :) Worth it!
GREAT! I really like this project... unique, interesting, well documented and worth a try!
Nah, no plane, want old school zeppelin or modern space shuttle. :)
This is awesome. Very nice steampunk feel :)
This is so fantastic! I hope you win!
Looks interesting this is ideal to give to your wife/lover/husband who has everything
This is awesome! My 9 year old daughter is already thinking fairies, dragons, etc... Because I really needed another project. LOL!
lovely!!!nice job done
Good job, very well done and really inspiring.....
Cheers dude
@lonesoulsurfer; Hi! I could not resist your Intractable (favorite spelling) title and watched and Liked and Tweeted your video... &quot;it's a tiny airplane in a lightbulb; that's all I'm sayin'&quot; Cheers! : ) Site <br>
Thanks for checking it out. It's good to see that i'm not the only one who digs planes in light bulbs ; )
This has to be one of the neatest instructables ever! I've been reading these since they started and this one has really got me going on trying to &quot;MAKE &quot;one! Thanks for a great project and very well done video.
Thanks mate - have fun making one!
Most excellent!!
Now, That's Bad ASS!
I just received a commercial bulb. Now I know what to do with it. Thanks so much for the instructable. <br>ps. your link does not work under modding a globe.
Thanks for the heads-up. All sorted now
Very nice work! I like it a lot. I may have to make something similar now. Thanks for putting this up.
Cheers - If you do make something similar post a picture so i can check it out!
I think this is a great project....reminds me a bit of the old universal films where they had the plane circling the earth...good work. You said that to remove frosting from inside the bulb use salt. How does that work? Do you just shake the salt around inside the bulb? Or........? Thanks.
Thanks mate. <br>If you put some table salt into the globe and swish it around for a bit the frosting inside comes away really easily. Once it was removed, I pushed a smakl peice of rag into the bulb and swished that around for a bit to clean-up any left over residue.
Can you please link to all the Stuff you used.
