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.
Always stay secure and protect your private data and gadgets when connected via USB. USB connections transfer information and power. UsbSafe² is a device that protects USB-connected hardware from excessive voltage, current, and unauthorized data access. Unfortunately, the practice of “juicing” (accessing data from devices connected to public charging stations) has become very common. UsbSafe² offers a unique combination of anti-juicing mode and fail-power protection. With UsbSafe², you'll feel safer no matter where you are or what you plug in, your valuable gadgets are protected and secured!
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.
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.
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~
This is an open source work by netizen aziddy, based on the classic Adafruit Feather 328P development board (the MCU master is Microchip's ATmega328P) and a mini electronic game console with a 128x64 OLED screen
Arduino development, weather, clock, reading, network distribution and other functions
An ultra-mini frequency probe designed by foreign expert David Johnson. This frequency probe can help you debug the circuit by displaying frequency and voltage. It can measure periodic waveforms from 1Hz to 5MHz with an accuracy of 0.3%. Of course, it can also be used as a voltmeter. Use it to tell you the current voltage value.
Design and implementation of solar power generation simulation system based on TMS320F28335
This board is a Swiss Army Knife for IoT security researchers, developers, and enthusiasts. The board can be used with different types of software, including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack-firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even Specific software requires writing your own software.
The Sensor Watch is unlike most smartwatches.
This dice mainly consists of an ESP8285-01F, six PCBs and 54 LEDs. Its structural design is very clever, and the exquisiteness of the structure is also reflected in the production process.
Protues simulation example (8051)-stepper motor control.rar
An open source multimeter design based on STM32F1/F3, with dual-range V/I, RMS measurement, continuity, component testing and other functions. The author has made all design files open source, which is very suitable for DIY entry.
Cruelfox, a forum expert, has updated his article to share with you an experimental idea of a CNC experimental power supply. The power supply uses two domestic chips, with a 3,000-word detailed explanation. He briefly talked about the first experimental power supply he made, whose shell was an aluminum medicine box and whose knob was a toothpaste cap. He mainly talked about the ideas and principles of the current mini PCB pocket version.
