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.

I want make a board that trigger a green and red LED with three wire, 0V, 24V and output of proximity switch. but i want output wire remain 0V when not connected.

We're building a BEC that can be connected to input 21.0V VBAT we'll need a 5V output and a 12V output

The LTC3109 from Linear Technology is a highly integrated DC/DC converter specifically designed for energy harvesting applications. It can operate from ultra-low input voltages as low as 30mV, utilizing a unique, proprietary auto-polarity architecture to function regardless of input polarity. The component is ideal for harvesting energy from thermoelectric generators (TEGs) and thermopiles, efficiently converting this energy to power remote sensors, wireless transmitters, and low-power devices. Key features include selectable output voltages of 2.35V, 3.3V, 4.1V, or 5V, a 2.2V low-dropout (LDO) regulator, a logic-controlled output, and an energy storage system to maintain operation during power interruptions. The LTC3109 is encapsulated in a small, 20-lead (4mm × 4mm) QFN or SSOP package, making it compact and suitable for space-constrained applications in HVAC systems, building automation, and industrial wireless sensing. Additionally, the power good indicator and the ability to use compact step-up transformers further enhance its suitability for low power, energy-harvesting systems.

This Gerber file contains the necessary information for fabricating the PCB design of a Bluetooth-enabled headphone. The design includes multiple layers, showcasing the electrical connections and component placements on both the top and bottom layers. Top Layer (Copper traces and components): The top copper layer is primarily responsible for routing the signals from key components such as the ESP32 module, MAX98357A audio amplifier, and the microphone. The ESP32 module, responsible for Bluetooth communication, is positioned centrally to optimize signal flow and minimize interference. Decoupling capacitors (100nF) are placed near critical components to ensure signal stability and noise suppression. Audio signal paths, as well as power distribution, are carefully routed to prevent cross-talk and ensure high-quality sound. Bottom Layer (Copper traces): The bottom layer contains the ground plane and additional routing for power and signal connections. The charging module (TP4056) and voltage regulator (AMS1117) are placed to manage power distribution, ensuring stable battery charging and regulated output for the ESP32 and other components. Connections to external interfaces such as the MicroSD breakout and auxiliary input are routed efficiently to avoid conflicts. Additional Components: All critical components are labeled, including decoupling capacitors (100nF) and resistors where needed, as well as external interfaces like the MicroSD card breakout. Mounting holes are provided for secure installation in a headphone casing, ensuring the board can be integrated seamlessly into the final product. The PCB is designed to minimize noise, with short signal paths and proper grounding for high-fidelity audio performance. This Gerber file ensures accurate manufacturing by containing data for copper layers, silkscreen, solder mask, and drill files.

This is a 2 stage IR sensor circuit intended to be used as a ballistic speedometer/chronograph for my Coilgun. I based it off a common design for IR proximity sensors. There are 2 output pins to a microcontroller, and +/-pins for 2 IR receivers, 2 IR emitters, and 2 green LEDs to show when the stage is active. When the beam is broken the voltage on the microcontroller output pins will change, allowing me to code proper coil stage firing timing. The potentiometers are for tuning the sensitivity.

This is a diode-based VCA audio compressor that works in mono. The compressor has LED-based gain reduction metering, input gain (preamp), output gain, and a fast-attack switch akin to the SSL channel-strip compressors. The module is to be powered by a regular outlet so it has an AC-DC converter.
