Summary: The Blue LED shine through the small holes punched out from a quart size tin paint can. It is neat how the bright LED light shines the punched out pattern on the ground around it.
Draw inspiration from the pictures and the idea to get your creative juices flowing in what you can do with this unique technique in LED lighting. Enjoy
Step 1: Design and Materials
1. Tin can with lid. Quart size is good
2. Printed out paper pattern or design
5. Awl or Ice pick (smaller tips work the best)
6. Wire for tin can handle (metal hanger or 16 gauge or type wire)
7. LED light circuit with batteries for illumination
8. Cotton towel (keeps can from rolling while punching holes)
10. Freezer (prevents the tin can from denting during hole punching)
Step 2: Punching Holes in Tin Can
Fill the tin can with cold tap water leaving about 1/4 inch from the top and put in the freezer for 24 hours.
With the tin can frozen you can punch-out the pattern.
Lay down a towel on a hard surface like concrete will work the best in punching the holes in the tin can. If the paper is getting to wet due to condensation then put the tin can back in the freezer for refreezing.
Punching the holes with an awl or ice pick rather than drilling is best. Drilling make the holes all uniform in diameter but punching the holes makes light different hole diameters thus give the tin can a more unique way it lights up. The LED will shine through the holes in the lantern.
The handle for hanging your LED tin can lantern can be made from a metal hanger or 18-16 gauge solid type wire. Punch two holes in the tin can for support. See the picture for reference.
Step 3: LED Light
The LED is mounted to the inside top of the lid with plastic screws and nuts.
