    ThirstIQ Cap

    High-level recreation of the ThirstIQ Cap wiring diagram using an ESP32-WROOM-32 with AMS1117-3.3 regulated battery input, inline ON/OFF switch, four touch input headers on IO32/IO33/IO25/IO26, shared I2C OLED and RTC on IO21/IO22, UART debug/programming header on TXD0/RXD0, BOOT and RESET pushbuttons on IO0 and EN, buzzer on IO4, common 3V3/GND distribution, and PCB preparation for a 160 mm x 100 mm 4-layer layout. Layout intent includes clean 3.3 V power distribution, local decoupling for regulator and ESP32, accessible external headers/buttons, short clean BOOT/EN traces, shared I2C routing, touch-signal separation from noisy power and buzzer traces, and ESP32 antenna keepout.

  • Fast Silver Flubber

    Fast Silver Flubber

    Create a schematic diagram of an electric fence controller using the NE556 dual timer IC. The circuit must include all components with clear electronic symbols (resistors, capacitors, transistors, diode, relay) connected by lines as in a real circuit diagram. Specifications: 1. Power supply: - Vcc = +12V connected to pin 14 of the NE556. - Pin 1 of the NE556 to ground. 2. Timer A (active 10 seconds): - Pin 2 (Trigger A) receives a pulse from transistor Q2 (contact detector). - Pin 6 (Threshold A) connected to Pin 7 (Discharge A). - R1 = 1 MΩ between Pin 7 and +12V. - C1 = 10 µF between Pin 6 and ground. - Pin 3 (Out A) goes through a 4.7 kΩ resistor to the base of Q1 (BC547 NPN transistor). - Pin 3 also connected via a 100 nF capacitor to Pin 13 (Trigger B of Timer B). 3. Timer B (rest 10 seconds): - Pin 9 (Discharge B) and Pin 8 (Threshold B) connected together. - R2 = 1 MΩ between Pin 9 and +12V. - C2 = 10 µF between Pin 8 and ground. - Pin 12 (Out B) can be optionally used to block retrigger of Timer A. 4. Relay driver stage: - Q1 = BC547 NPN transistor. - Base connected through 4.7 kΩ resistor to Pin 3 (Out A). - Emitter to ground. - Collector connected to one side of the relay coil. - Other side of relay coil connected to +12V. - A diode 1N4007 placed in parallel with the relay coil (cathode to +12V, anode to collector of Q1). - Relay contacts switch the +12V supply to the electric fence energizer. 5. Contact detector: - Shunt resistor ≈0.1 Ω placed in series with the fence output. - Q2 = BC547 NPN transistor, base connected to the shunt, emitter to ground, collector to Pin 2 (Trigger A). - When current flows through the shunt, Q2 provides a trigger pulse to Timer A. Please draw the schematic in a standard style with components connected by straight lines, not in block diagrams. Show clear pin numbers of the NE556 and all external components.

  • LW18-S

    LW18-S

    I2C to dual PWM controller. The LED-Warrior18, manufactured by Code Mercenaries, is an I2C to dual channel PWM LED driver specifically designed to provide seamless brightness control for LED applications. This component, available in SOIC8 package (LW18-S) and as a ready-to-use module (LW18-01MOD), offers dual 16-bit PWM outputs with a dimming range from 0.001% to 100% and operates at a PWM frequency of 730 Hz. It supports programmable period lengths for higher-frequency or lower-resolution operation and includes an 8-bit data to logarithmic mapping feature for smoother dimming operations with just 256 steps. The LED-Warrior18 is engineered for minimal external circuitry with a 5V power supply requirement, offering ease of use in various lighting applications. It also features a sync mode for synchronized control of multiple units and customizable power-on status settings, making it highly versatile for standalone operations or integrated systems. Additionally, custom variants of both the chip and module are available, catering to specific application needs. The module version, LW18-01MOD, simplifies integration by including terminal blocks and supporting up to 4A load sink current for each output. The LED-Warrior18 stands out for its straightforward interface and operational flexibility, providing a comprehensive solution for advanced LED dimming and control projects.

  • Multiple Fan Board

    Multiple Fan Board

    Attach multiple fans from the output of a board that turns on and off one fan. The original fan output is used as a signal to turn a MOSFET on and off to turn on 5 fans from the same original logic. An external power supply powers all the fans.
