I love making art that has multiple views to it. This complexity allows for a wider range of interpretations. A prime example is some of my reactive resin artworks that look different in regular light, UV light and in the dark.
Please take care of each other.
I built myself a piezo hydrophone. The metal ring used was kept from a disassembled camera lens. I sealed around the edges to make a box before casting the whole thing into resin.
Resin Tip: If you have a lighter handy you can quickly brush the flame over the surface to pop the bubbles during initial casting to avoid the bubbles seen in the bottom photo. 😉 But in this case I did not have one handy before the resin setup. Far as I can tell keeping them does not hurt the hydrophones function since it’s active side faces outward.
