Just ordered some parts to prototype an experimental tactile interface for "feeling" visual textures.
I ordered a piezoelectric actuator, some through hole op-amps to drive it, a breadboard, some prototyping wire, some 1/8" prototyping jacks, an assortment of through hole resistors, and a big box of small plastic drawers to organize my parts.
I'm gonna drive the piezoelectric actuator by driving the op-amp with the audio out from my sound card on my PC. I'm planning to prototype a tiny MCU and tiny camera separately.
I'm so excited for this project.
