This is a simple output capacitor bank for use in signal powered or dual supply headphone amplifiers. The output capacitor bank protects the headphones from DC current.
LED Indoor Wall Thermometer with Power Adapter
Powerful 1km 6-10 channel remote control, suitable for DIY projects such as drones and cars.
This is a 100w mono audio amplifier board. This project can easily play speakers up to 100w. I used two 2SC5200 transistors and a 30-0-30 transformer in this project
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
In theory, it could connect to Google Calendar and show today's events while still being ongoing. Also on the list of features to be implemented is a switch or sensor that changes mode when the pen is removed, and buttons or touch controls for the user interface.
MiniQ is a mini quadcopter that is open source from hardware design to control algorithm. The algorithm used for the Altitude Heading Reference System (AHRS) is the DCM complementary filter. The system calculates the height and controls the output PWM of the four motors 1600 times per second. It can be controlled remotely via Bluetooth (Bluetooth Serial Port Profile).
Author Lennert Wouters demonstrated how to execute arbitrary code on Starlink user terminals via a custom modchip injected with voltage faults, and notified Starlink of these vulnerabilities.
Although the details are open source, the author does not sell the finished product, nor does he provide details of the modified endpoint firmware and fault injection used in the attack.
The transformation is to use a Raspberry Pi microcontroller
The power supply has a stable symmetrical +/- 40 V to ensure optimal performance.
Maximum power (THD 1%) approaches 100 W into 8 Ω load and 190 W into 4 Ω load (see measurements). All parts are through-hole, making it easy to build the amplifier. The design is completely symmetrical.
Every house has a doorbell. When a visitor arrives at a home, he looks for the doorbell switch and rings it to let us know his presence. What if a person coming to your home cannot find the doorbell, or the person is too short to reach the doorbell? The object detection circuit installation below is for reference. The circuit will automatically sense the presence of a person and ring the doorbell.
The LPCXpresso family provides a powerful and flexible development system for NXP Cortex-M microcontrollers. The LPCXpresso43S67 board was developed by NXP to enable evaluation and prototyping of the LPC4300 series MCUs, featuring the LPC43S67 in a 100-pin BGA package. LPCXpresso™ is a low-cost development platform provided by NXP that supports NXP's Arm-based microcontrollers. The platform includes a simplified Eclipse-based IDE and low-cost target boards with a JTAG debugger. LPCXpresso is an end-to-end solution that supports embedded engineers developing applications from initial evaluation to final production.
