I’m putting together a small outdoor rack and need an electronic sensing solution that can tell me, in real time, whether something has been placed on—or removed from—each shelf. Cameras are off-limits, so I’m looking for a clean sensor-based approach that works equally well with mixed materials such as metal, plastic, or any everyday composite an item might be made from. Because the rack will sit outside, the hardware must shrug off normal weather exposure—sun, light rain, the usual seasonal swings—but it doesn’t have to survive arctic freezes or tropical monsoons. A compact, low-power design is preferred, and I’m open to ultrasonic, IR, capacitive, load-cell, or any other sensor technology you feel is best suited to the job, provided it st...

I’m building a “Gorilla Tag” monkey that behaves just like the in-game avatar when I hold two Meta Quest-style wireless controllers. The right-hand controller must drive the right arm in real time; every tilt, swing, or reach of my own hand is mirrored by the toy, and its fingers curl or extend when I press the physical buttons. The same button layout is mirrored on the left controller, with one key difference: the right joystick swivels the torso, while the left joystick pans the head. The toy has no legs or hidden wheels—it should locomote exactly as a gorilla tagger would, pushing itself along the ground with believable arm physics. Build requirements • Wireless link between controllers and toy (low-latency Bluetooth or comparable protocol)....
