Introduction: Mind Gear Lighted Wall Fixture
Hello Instructables Lovers :-),
Recently I had to get my wrist watch repaired as it fell down from stairs. Guess what, it was a small misalignment of a watch gear, so the watch guy repaired it in front of me. He used a a small lamp to see details inside the watch and while I was watching it with curiosity, I noticed how cool all those gears were looking as the light was peeking from gear teeth. There my friend sparked an idea of making something like what I call as Mind Gear Lighted Wall Fixture.
If you Google watch gears, you will know how i got the idea.
Luckily I had enough cardboard left after I made this Lamp. So I decided to use that. Initially my idea was to only make something that shows gears but as I progressed,the idea of making it Mind Gear evolved.
So lets get started.
Step 1: Required Stuff
- 2 big cardboard sheets (Mine is 45x25 inches), you have to decide this size by yourself as it depends on the size of the fixture you want to make. Luckily I had a Triple wall sheet of that size.
- A heavy duty cutter.
- Some glue like Elmer's or Fevicol.
- 2 Toilet roll cardboard rolls.
- Acrylic colors metallic shades of Black(Keep 2 bottles of 15g at least), Silver, Gold and Copper.
- Acrylic medium for color density.
- A big geometrical compass or engineering compass, luckily I got a wooden one from the store which was big enough for me.
- OPTIONAL: Hot glue gun and sticks (I chose this to speed up gluing otherwise normal glue is sufficient).
- LED strip lights (about a 3-4 feet).
- Some electric wire
- Soldering Iron and other related stuff like wire and flux. (If you can get the soldering done at a local electrical store, you may not need it)
- Some painting brushes (I used size 6 and 12).
- OPTIONAL : A drill and hole saw (If you can cut good holes in cardboard, you can leave it. I found it useful).
- A Pencil.
- An insulated tape.
- Some very basic drawing skill (I am not really very good at drawing).
- Our best friend patience for all time support :-)
- Lots of drinking water to keep our mind gears hydrated ;-)
- Some green tea, chai or coffee would be a plus :-)
Step 2: Making the Gears
- 1 Circle of radius 6.5 inches (The bigger)
- 2 Circle of radius 5.5 inches (The medium)
- 1 Circle of radius 4.5 inches (The smaller)
- 1 Circle of radius 2.5 inches
Once the circles are cut using our heavy duty cutter, lets play geometry:
- Draw an inner circle of radius 5.5 inches inside bigger circle.
- Draw an inner circle of radius 4.5 inches inside medium circle.
- Draw an inner circle of 3.5 inches inside the smaller circle.
- Draw lines as shown in Image 1, see details in Image 2
- Cut the teeths (Image 3)
- Repeat this for medium and smaller circle
- End result is shown in Image 4. The circles smaller in size relative to each of three circles are just placed to show how we will be using them.
I could not find or think of any better ways to cut the gears using some geometrical formula, if you have a better method, please share in comments.
Now do as follows :
WARNING: When you are drilling a hole in cardboard using holesaw. Do not do it on floor, put a thick scrap wooden piece right below the cardboard where you need a hole. Failure to do so may break the drill bilt and may cause an injury as well.
- Using hole saw drill a hole in the center of all the 6 circles large enough to fit the toilet cardboard roll. (Image 5). I think it create a very neat hole.
- Also drill three holes in the bigger gear as shown in Image 7.
- If you cut the cardboard the way I had explained you, you will find that many small pieces of different sizes and shapes as byproduct. Glue 3 pieces on medium gear as shown in Image 6.
- Paint the gears as Bigger (copper), Medium (gold) and smaller (silver). Let the arrangement dry. The outcome should look like Image 6.
- Once paint dry glue the circles we cut for padding at the back of each gear and let them dry. Make sure to match the hole in the middle.
Lets make small rotary gears (I don't know what else to call them:) ) in next step. Now is also the good time to grab some tea or coffee :).
Step 3: Making the Small Rotary Gears
- Take two toilet roll cardboard.
- Cut them into half (Image 1)
- Take some scrap cardboard and cut 24 strips of size 1 inch (Image 2)
- Glue the arrangement as shown in Image 3.
- Make 3 such arrangements (Image 4). Let the glue dry.
- Paint them using Metallic Black (Image 5)
- The final result should be like Image 6.
Step 4: Making the Head
Take big cardboard sheet and draw an outline of the face. (Try it its not difficult, I am not good at drawing either, and I do admit that the head looks like human looking aliens in the movie Prometheus.. ha ha, lets call it modern art:))
Cut the drawing nicely (Yes, this is the test of your hand skills) and paint it using using metallic black.
My sheet has many wounds :),but once they are painted, I think it added to the design.
See the image above for the outcome.
While the head is getting dried, lets make some arrangements to light up our gears in the next step.
Step 5: Adding Some Lights to the Gears
- Cut the LED strip into 3 pieces. Cut them such that they can stick around the circle we used as padding for each gear respectively. (Image 1)
- Cut electric wire into 4 pieces of about 10 inch() and solder them with LED strip pieces to complete the circuit. We are doing this so that we can have an evenly looking light effect for all gears (Image 2). You should solder the wire starting from the longest strip to shortest. I realized after soldering that my wires were too long and created a mess. If soldering is too much for you, get it done at a local electrical store.
- Remove the sticker of LED strip and stick it behind the copper colored gear (Image 3).
- Similarly stick the strip in other two gears.
- Test to ensure that they are lighting up.
- Heat your hot glue gun (or use glue if can wait for the glue to dry) and cut a small cardboard strip and join the copper and silver gears. Join the gears as shown in Image 4. (Sorry forgot to take picture of the strip used for join).
- Using some insulated tape, organize the wire mess (Who cares if they are hidden nicely :-) ) behind the gears (You can avoid this by using small wires) Image 5.
- Using hot glue stick the golden gear on top of copper gear so that it covers one of its three holes.
Step 6: Giving the Head Some Gears. Finally :)
- Insert the small rotary gears(we created in step 3) in each of the gear, if the hole in the center is perfect then you don't need to glue it.
- Cut small piece of wire (about 10 inch), put it inside the gap where copper and golden gear overlaps, then insert both ends of the wire in the cardboard head (See image). Pull the wire from behind and bend so that it does not get loose.
- Also make a hole using some pointed object in the cardboard head right behind the gears to pass electric wire (See Image)
- Also create a wire loop and insert in the cardboard head. So that you can hang the head using it (Sorry no picture:( )..
- Hang it on the wall and light up.
