I need a working prototype of a compact pool-cleaning robot designed, built, and shipped to Pune by 20 March. Its two core tasks are debris collection across the pool floor and reliable wall-climbing so it can scrub and vacuum vertical surfaces as well. The unit must run on a rechargeable battery pack—no cords in the water—and be steered with a simple handheld RF remote (forward, reverse, left, right, start/stop). A smartphone app or timer isn’t necessary; keeping the hardware lean is key because the entire build, plus packing and freight, must stay within an 18 k INR ceiling. I’m open to clever use of 3-D printed housings, sealed brushed or BLDC thrusters, and readily available filters to hit that cost target while ensuring waterproof integrity. Good buoyancy cont...

I need a compact, single-fire line smart light switch designed around the ESP32-C3, strictly for residential use and housed in a PC-V0 enclosure. Because there is no neutral wire available the power stage has to ride on the leakage current, so I am counting on a proven AC-DC buck such as the Hi-Link HLK-PM01 (or similarly tiny module) and a reliable bypass-capacitor network that keeps the MCU alive even with very light loads attached. Switching must be silent and fast: think BTA16 (or comparable TRIAC) driven through an opto-isolated MOC3041 gate. Absolutely no mechanical relays are allowed. Behind the faceplate, the board should hide an HLK-LD2410 microwave radar sensor; its trigger will be combined with a capacitive interface that recognises multiple touch points on the glass front. Sp...
