Put on your safety gear before you begin. Mix 0.30 grams of polyvinyl alcohol and 10ml into your glass beaker. Wrap plastic wrap on the top of the beaker and heat the beaker for 15 seconds. Check the solution to see if it is dissolved.
Heat the solution in 15-second intervals until the solution is dissolved. Avoid boiling the solution by waiting 10 seconds between each heating. Mix 0.035g of Ru(bpy)3(BF4)2 with your mixture with a spoon until it completely dissolves.
Turn on your ohmmeter and place the diodes on one side of your glass. Find the conducting side by finding the side that reads 20 to 30 ohms. Place a piece of double-sided tape on the other side of the glass.
Stick the glass to the center of the fan. Dip your cotton swabs in the chemical mixture you made earlier and apply it to the center of the glass piece. Put up your splatter guard and turn the fan on at 2,500 RPM for about 30 seconds.
Remove the splatter guard and apply another coat of mixture. Repeat this process four times and remove the piece of glass from the fan. Remove the piece of double-sided tape and throw it away.
Cut out a piece of tin foil that is large enough to fit over top of your glass piece. Punch a hole with your metal punch through the tin foil.
Remove moisture from your glass and your template by running them underneath your hair dryer for two minutes. Lay your template on top of the piece of glass on the conductive side.
Apply a dot of liquid metal electrode through the template and onto the glass. Let it dry for several hours. Place the positive end of the power supply onto the nonconductive side of the glass. Place the negative end on the metal electrode to light your OLED.
