The MPC8272ADS board is designed to aid hardware and software developers of the PowerQUICC II family by providing an evaluation platform for MPC8272/48 derivatives in the 516-pin PBGA (ZQ/VR) package.
The MAX5953A provides a simple and inexpensive, yet complete, nonisolated power solution for a powered device (PD) in a Power-over-Ethernet (PoE) system. The circuit provides the PD with detection and classification signatures in compliance with the IEEESM 802.3af standard, plus programmable inrush-current control, an integrated power switch, a PWM controller, and integrated high- and low-side switches. The buck step-down converter is capable of > 80% conversion efficiency while delivering 12V at 0.85A.
This video records the entire process of the author and his team building a low-cost ornithopter. The video explains in detail the mechanical structure design, power transmission, wing flapping angle control, electronic system design and selection of the ornithopter. At the same time, the author has open sourced all design-related schematics, PCB, source code and other materials for reference by interested enthusiasts.
Intel has open sourced a car with a total parts price of less than 50 US dollars, which costs about 350 yuan in total. With a mobile phone, it becomes a self-driving car.
Reliable health monitoring has traditionally required us to tether ourselves to machines that record our vital signs around the clock. However, outside of clinical settings this is rarely practical. We developed HealthyPi v4 in part to address this challenge. Building on its predecessor, HealthyPi v4 is a fully open source standalone vital signs monitor with wireless and wearable capabilities.
Label-free pose estimation from user-defined features via deep learning for all animals
Arduino® Nicla Vision is a ready-to-use standalone camera for analyzing and processing images at the edge. It's suitable for asset tracking, object recognition and predictive maintenance thanks to its 2MP color camera, smart 6-axis motion sensor, integrated microphone and distance sensor. Quickly implement sensor nodes that send collected data to the Arduino® Cloud (or third-party vendor service) via integrated WiFi/BLE connectivity.
Wigl can hear the notes of any instrument and respond with movements, lights and special dances! Wigl helps motivate children and adults to practice their instruments. By sequencing the notes, you can program special dance moves for your Wigl. This combination of right-brain creativity and left-brain logic makes it a unique robot for any home. How does WIG work? Wigl has a microphone, a microcontroller (brain) and some motors for movement. Wigl is always listening for notes, and through some complex math it can hear individual notes.
The MAXREFDES1247 is a miniature, 12V output, isolated power supply that can deliver up to 1A of load current.
The MAXREFDES1213 is a reference design showcasing the MAX32630FTHR and MAX11311, as well as several other Maxim products, that demonstrates a small size, low-cost, portable electronic load (E-load) for testing power converters and PMICs.
Built-in gyroscope, buzzer, supports multiple fast charging protocols, 128x64 OLED screen, standard T12 fixed bayonet. Regarding the problem of grounding the soldering iron, you can use the PD power supply of Mac and prepare a triangle extension cable to solve the problem perfectly. Or using a power bank directly is not a big problem.
Suitable for long distance RS-485 networks. The design provides transient protection from the effects of ESD, EFT and surge transients as specified in the IEC 61000 transient immunity standard.
The project is a small desktop-level robot tool that can be used to help you control your computer, etc. Its functions can be defined by you. The inspiration for the appearance design is EVE in WALL-E~ The robot has a USB communication display screen function, has 6 degrees of freedom (one roll and pitch for the hand, one for the neck, and one for the waist), and uses its own modified special servo to support the joints Angle return.
This document details the Oceanside (MAXREFDES9#) subsystem reference design, a 3.3V to 15V input, ±15V (±12V) output, isolated power supply. The Oceanside design includes a high-efficiency step-up controller, a 36V H-bridge transformer driver for isolated supplies, a wide input range, and a pair of adjustable output low dropout (LDO) linear regulator. Test results and hardware files are included.
APM (ArduPilotMega) is a flight control product launched by the DIY Drones community in 2007. It is the most mature open source hardware project today.
This is a fun electronic toy car that features power-ups! The author uses color sensors and magnetic switches to trigger fun tricks like acceleration, deceleration, and rotation. It draws a lot of inspiration from Mario Kart.
After a failed Kickstarter campaign, the author has now open-sourced the software, hardware, and mechanics.
This open source has a complete host computer, slave computer and schematic diagram, as well as a detailed design paper.
Zhihui Jun designed and produced a portable pocket monitor (& power bank) to solve personal pain points. There is no room for improvement in terms of appearance~
