Step 1: Step 1 - Required Materials
- Metal bowl - this will be your planetarium dome
- Base, I used a microwave splatter guard (*note that the bowl and the base should be a good fit together (see photo below)
- A few nails
- A metal file
- Wooden block
- Soldering equipment
- High Power LED
- Toggle Switch
- Wall Adapter Power Supply
- Hook-up Wire
Step 2: Step 2 - Punching Holes in the Dome
If you want to create constellations, print out a sheet that has the constellations and place the sheet over the bowl as you drive a nail through it.
Step 3: Step 3 - Prepare LED
Step 4: Step 4 - Connect Switch and Assembly
Next I soldered the wire to the switch, attached it to the base and connected it to the power supply. I cut the end off of the Wall Adapter Power Supply so that I could connect one end to the switch and the other to the LED. For the best effect, it is important to make sure light doesn't escape from your enclosure except through the designated holes in the dome, so I covered my base with black paper.
Step 5: Add Dome
Make sure the LED isn't shorting on the enclosure's base.
Check to be sure your soldering is secure on terminal and switch.
Check for damaged components.
