This week we continue to develop the prototype we have for Project 2
We experiment with using the laser cutter to engrave the pattern of the circuit board on the bioplastic (gelatin)
The preset data for the leather engraving works but the best effect is changing the number of the power to 30% (and using the thickness mode)
In addition, we downloaded the paper pattern for the collar and tried to cut the current bioplastic we have based on the pattern
We also experimented with growing crystals on the PCB board. We tested the recipes of the alum powder and borax power. We find that the crystals formed by the alum solution are closer to an opaque white color, while the crystals formed by the borax solution are transparent
We also tested the recipe for growing crystals on the LED.

We have found that crystals from reused (heated again after crystals have formed from the solution) borax solutions also tend to form opaque white crystals.
In addition to the circuit board, we also tested how the borax would grow on the fabric, and we found that the shape of the crystal would be almost the same as the container that we put the fabric in.
