Pin-Hole Planetarium

• There are many different ways to make your dome. I used a nail and hammer. I had an extra hand help me with this step as I hammered a nail through the bowl into a wooden block — simple, yet effective. These holes should be relatively small since you want your projections to look like the actual night sky.
• Make sure to file down the dome. The punched holes are sharp. 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.

Prepare the high power LED by soldering wire to its terminals.

• Connect switch and assembly. 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.
• It is important to make sure light doesn't escape from your enclosure except through the holes in the dome. In order to ensure this I covered the base with black paper.
• Secure the LED on top of the base with glue or double-sided tape. Warning: LED is extremely bright.

• Place the dome on top, turn off the lights and enjoy!
• Troubleshooting Issues: Make sure the LED isn't shorting on the enclosure's base. Check to be sure your soldering is secure on terminal and switch.
