Make Your Own Custom Glowing Etches

Step 1: Materials

1. Some 1/4 inch(or thicker but 1/4" is best) plexi glass. You will only need 1.5"/1.5" pieces
2. LEDs. Small 1/8" ones. Any color.
3. A sharp pointy object
4. A paint stirrer or other piece of wood/plastic 1/8" thick.
5. some conductive tape. Aluminum foil and glue should work.
6. 1/8" drill bit and drill
7. Power supply right for the LEDs you have. I used a 4.5v wall transformer and a 100 ohm resistor.

Step 2: Make the Stand

1. Put some conductive tape on either side of the paint stick/other object. (going across the long way on the biggest sides towards one medium sized side of the stick/other object.)

2. PARTY!

3. clean up.

4. Find a way to make it stand up with the taped edge up. For now I'm using a vice.

5. Hook up a power supply to the two pieces of tape. (+) to one side and (-) to the other.

Step 3: Carve the Plexi Glass

Use the sharp pointy tool to carve your design into the plexi glass. It doesn't have to be deep. I have a few tips for this process.

  • To separate the paper from the plexi glass easier, soak them in citri-solve for a minute or so.
  • Put a picture under the glass.
  • Have only one light on when you are carving.
  • line up the shadow of the tip of the carving tool with the line on the paper you want to carve.

Step 5: Enjoy!

Put the LED into the hole in the plexi glass and put the whole thing on the stand. Enjoy!

  • Try different colored LEDs
  • Take pictures of your designs and post them in comments!
