Giant Etch a Sketch Interactive exhibit designer Mechanical engineer—XY gantry

Standing Large etch a sketch type interactive art project showing the mechanical hardware that is controlled by the user with the knobs. It should show all the wire and rods in the back ground and the art should be drawn on a white board or some better canvas idea. Must wipe clean easily from the front so no one has to approach it and use an eraser on the board. must light up at night. Chat GPT describes it as An approximately 7-foot-wide × 6-foot-tall red enclosure. Two oversized physical knobs. Knobs connected to rotary encoders. An enclosed screen or drawing surface controlled by a rugged XY mechanism. A large physical “shake/reset” lever—or a reset button disguised as shaking. Sealed bearings and electronics. Wide, stable base engineered for wind. Modular sections that fit your and can be carried by a small crew. Low-voltage LED edge lighting so bicycles do not hit it at night. One thought is A digital system will survive better and allow a convincing “shake to erase” animation. A belt-driven physical stylus behind polycarbonate would feel more authentic, but it will be considerably harder to keep operating in alkaline dust.
