Looking for someone in India, Delhi NCR Region. Thanks

I’m developing a dedicated handheld that will operate offline. No Wi-Fi, Bluetooth, cellular, or any other radio is required, so the entire design has to function in isolation. Because of that restriction I’m open to whichever operating system keeps the footprint light and the boot time quick, whether that’s a stripped-down Android build with networking stacks removed or a fully custom OS. but more likely just on/off. then a button to run. Your task is to take the idea from concept to a working prototype. I’ll need the electronic design (schematic, PCB layout, and component selection), a daylight-readable display, a rechargeable battery able to power at least eight hours of continuous use.. Low power consumption, immediate on/off and rock-solid stability. Deli...

I already have a universal BLDC ceiling-fan driver PCB running perfectly from mains power; what it lacks is an Arduino brain. My goal is to plug an Arduino (Uno, Nano, or whichever you prefer) into the existing driver so I can: • adjust fan speed across its full range, • reverse the direction on command, and • set on/off timers, all through a small set of physical push-buttons mounted near the fan. What I need from you is a clean, well-commented sketch plus a minimal wiring diagram that shows exactly where every button, resistor, and logic-level signal ties into the driver board. If any level-shifting, opto-isolation, or triac/FET gating is required, please spell that out and include the component values. Debounced button handling and non-blocking timer logic (e.g., u...

I’m building a proof-of-concept noise-reduction module destined for consumer-grade electronics. My priority is an electronic schematic that delivers two core capabilities: active noise cancellation and echo reduction. The circuit must be small enough to embed in another typical product that will be mentioned later on as the project develops. Here’s the flow I have in mind. First, we collaborate on the signal-processing topology—feed-forward, feedback, or hybrid—then translate it into a detailed schematic and PCB layout (Altium, KiCad, or your preferred EDA). Once the draft design is ready, I’ll need simulations or bench measurements that prove at least 20 dB attenuation in the 50 Hz–2 kHz band while holding latency under 10 ms; please include SPICE plot...
