Etapa 1: Recolección y Almacenamiento de Energía Entrada: tus cactus en serie (ej. 15 cactus × 0.5 V = 7.5 V). Componente clave: Supercapacitor o batería recargable de baja capacidad (Li-ion o LiFePO4, 3.7V-7.4V). Diodo Schottky entre los cactus y el capacitor para evitar descarga inversa. 🛠 Ejemplo de componentes: Supercapacitor de 5–10 F, 5.5 V o batería de 3.7 V (tipo 18650). Diodo Schottky 1N5819. Módulo cargador TP4056 (si usas batería). Etapa 2: Aumento de Voltaje (Boost Converter) Conversión de 3.7 V / 7.5 V DC a 110 V AC. Necesitas: Boost Converter (DC-DC Step-up) de hasta 300 V DC. Inversor DC-AC (pequeño, tipo mini inverter para LEDs) que convierta ese voltaje a 110 V AC. NOTA: Algunos focos LED pueden funcionar con 110 V DC directamente, si quieres evitar el inversor. Etapa 3: Detección de Noche Sensor LDR (resistor dependiente de luz) conectado a un comparador (ej. LM393) o a un microcontrolador (como un ATtiny o ESP8266 si quieres funciones extra). Al bajar la luz solar: El comparador activa un MOSFET o un relé que conecta la energía almacenada al foco.

A buck boost converter that can be power from a LI-Ion battery and output 3.3V @500 mA. Powered by thr TPS63051YFFR and in the same package as a standard adafruit buck converter Imput Voltage: 2.5 V to 5.5V

This design is a power supply system that converts 240V AC (60Hz) into three regulated DC outputs. The architecture includes an AC rectifier and filter to form a DC bus, followed by a boost converter (MT3608) that steps up the voltage to 5V. From the boosted output, three voltage regulators provide different outputs: a 5V rail directly from the boost converter, a 3.3V rail using the AP7333-33 buck converter, and a 1.8V rail using the AP7333-18 buck converter. Protection components such as Schottky diodes and stability capacitors are incorporated, along with LED indicators for charging and power status. #PowerSupply #VoltageRegulation #ACDCConversion #BoostConverter #BuckConverter #CircuitDesign #PowerSystemArchitecture
