OpenEarable aims to enable ear-based sensing applications by providing a flexible open source hardware platform. It integrates a range of sensors, including a 9-axis inertial measurement unit, ear canal pressure and temperature sensors, inward-facing ultrasound microphone, speakers, buttons and controllable RGB LEDs. With these capabilities, OpenEarable provides researchers and developers with the ability to explore a variety of application scenarios.
OpenEarable controls and transmits sensor data via BLE (Bluetooth Low Energy). Audio is played from or recorded to the internal SD card. OpenEarable is compatible with the provided dashboard and Edge-ml.
A programmable resistor is an electronic device whose resistance can be adjusted, usually through a digital signal. Programmable resistors come in the form of integrated circuits (often called digital potentiometers) as well as stand-alone devices/expansion cards. There are many different applications, each with its own set of requirements.
Range 1Ω - 999.999KΩ.
Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability.
The basic functions of USB-C are supported, such as high-speed communication and charging functions. Then this design solves the problem of painless switching between one host and multiple devices, or one device and multiple hosts.
The analyzer host computer directly uses Wireshark. The hardware is implemented using Cypress CY7C68013A MCU + Lattice LCMXO2 FPGA + Microchip USB3343 USB PHY
2 Layers PCB 10 x 18 mm FR-4, 1 mm, 1, HASL with lead, White Solder Mask, Black silkscreen;Cofigurable RS485 TX-RX transceiver for long range serial LED strip communication
2-layer PCB 38.7 x 49.5 mm FR-4, 1.6 mm, 1, with wire spray tin, red solder mask, white silkscreen; lightning detector.
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.
A simple USB switch so I can swap a keyboard or mouse between two computers.
It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.
PCB for clipping onto Guillemot MAXI Gamer 3D Voodoo graphics accelerator. The common memory size for these cards is 4 MB. With the help of PCB you can get Voodoo up to 8 MB.
The basic Escornabot can be programmed to perform a series of actions using the robot's buttons. From this point of view, imagination is the only limit on possibility.
