Inspired by this Instructables post, a friend of mine decided to create something similar for his wedding.
The bases were a bit more advanced than the suggestion, and all were created by a friend of the groom. They consist of a block of wood, a battery holder and 3 red LEDs.
The plates were etched & cut on our laser over a period of about 15 hours. It was about one hour per plate, 12 of which we used, 3 were used to perfect the process. This video shows a time lapse of the process. We had some trouble initially with clouding on the plate, especially around the letter “o”. We fixed this by adjusting the power and speed of the laser and refining our post etching cleaning process.
After the plates were etched and cut they were soaked in water & simple green for about 30 seconds, then wiped off with a microfiber cloth.
The cards were then set up at the reception hall prior to the wedding, and remained lit throughout the evening.
The Bride & Groom were pleased with the results as were we. While it was a lot of work, the project resulted in a unique keepsake for each wedding guest and the wedding party.
