Hello, this project is technically achievable and aligns well with ultra-low-power embedded design. I will design a nano-power architecture using a supercapacitor energy store and an efficient boost regulator such as TPS61291 to maintain a stable 3.3V rail. For the <1µA standby target, I will use ultra-low-power components like TPL5110 and TLV3691. The FSR will be implemented with dual comparator thresholds to trigger the green (>50g) and red (>300g) LED alerts. I will simulate the timer cycle and pressure thresholds before finalizing the schematic in EasyEDA Pro. The PCB will be a compact ≤15 mm strip and fully compatible with the JLCPCB/LCSC SMT library. You will receive schematic, simulation results, Gerber, BOM, CPL, and a clear power-consumption report for verification.

Hi, Your Kinetic Pulse PCBA concept is a very interesting ultra-low-power design challenge, especially with the constraint of using only a supercapacitor (no batteries) and maintaining <1 µA standby consumption. I have experience designing nano-power embedded circuits and energy-harvesting systems, including supercapacitor-based power management and ultra-low-leakage sensing interfaces. I can design a compact EasyEDA Pro schematic and PCB optimized for JLCPCB SMT assembly, while ensuring all components are available in the LCSC library. For this project, my approach would include: 1. Energy Harvesting & Regulation • Rectification and protection stage for the induction coil input • Ultra-low-IQ boost converter capable of operating from ~0.7 V • Efficient supercapacitor charging and controlled discharge to maintain a stable 3.3 V rail 2. Nano-Power Control Logic • Sub-µA timer architecture for the 40-second alert cycle • 100 ms buzzer activation with minimal energy overhead • Careful component selection to maintain total idle current <1 µA 3. Pressure Detection System • Precision comparator circuit for the FSR dual-threshold detection • Green LED trigger (>50 g) and Red LED trigger (>300 g) • Low-leakage biasing network to preserve stored energy 4. Compact PCB Implementation • ≤15 mm width PCB strip layout • Optimized routing and ground strategy for stable sensing • Full Gerber, BOM, and CPL package ready for JLCPCB SMT Looking forward to collaborating on this project.

The specification combines energy harvesting, ultra-low power design (<1 µA standby), boost conversion from 0.7 V, supercapacitor-only storage, timed audio output, dual-threshold sensing, and strict PCB constraints, all for a fully simulated and production-ready design. I can technically design this type of nano-power architecture. However, the proposed budget of $100 total is not realistic for the engineering depth required. This project involves: • Ultra-low leakage component selection (true nano-power comparators, timers, boost converter with sub-µA quiescent current) • Cold-start boost topology capable of 0.7 V input • Supercapacitor discharge modeling • Leakage budget calculation at PCB level • Functional simulation (timer + dual-threshold analog logic) • EasyEDA schematic + constrained 15 mm PCB layout • Full JLCPCB manufacturing package • Power runtime modeling Even selecting a boost IC that can cold-start below 1 V and maintain <1 µA system leakage is non-trivial. Most “nano-power” datasheets hide real leakage paths that must be carefully evaluated. Realistic engineering cost for this scope: $900 – $1,500 If you must stay near $100, I can offer: • Component selection guidance • High-level architecture recommendation • Leakage budget outline But not full simulation + production-ready PCB. If you would like to proceed with a properly engineered ultra-low-power design, I can outline a technically sound architecture and adjusted milestone structure.
