Desktop CNC machines often use stepper motors, often because they do not require position feedback sensors, thus reducing system cost. But there are situations where a position feedback sensor is needed or necessary, and the power output of a stepper motor, especially at high speeds, becomes a bottleneck for those who want a better performing machine.
FossaSat-1 uses cheap LoRa modules to provide free and open source IoT communications around the world, allowing students to communicate with satellites for less than 20 euros.
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!
The MAXREFDES1247 is a miniature, 12V output, isolated power supply that can deliver up to 1A of load current.
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 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.
Design features: Bus power evaluation, quick and easy testing of different bus power filters, configurable module application for master or slave, DC blocking bus capacitors, onboard receiver/transmitter enable/disable pull-up/pull-down resistors
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 manipulator is the main tool for exchanging tools in the automatic tool changer. It is responsible for sending the tools from the tool magazine to the spindle, and then returning the used tools from the spindle to the tool magazine. The design idea is to use the movement of the manipulator to change the tool of the machining center. The rotation of the manipulator is realized by a rotary pneumatic cylinder or a rotary pneumatic cylinder, and its power is realized by the drive system. The automatic tool changer of a machining center is usually composed of a tool magazine and a manipulator. It is a symbol of the machining center and a key link to the success or failure of the machining center. Therefore, all machining center manufacturers are working hard to develop automatic tool changers with fast action and high reliability in order to achieve good results in the fierce competition. Automatic tool changers are the core content of machining centers, and each manufacturer is keeping it secret. Very little relevant information is disclosed, especially the robot part. The knife extraction and knife insertion actions of the manipulator are mostly completed by the pneumatic cylinder or the action of the pneumatic cylinder. The entire manipulator is composed of a mechanical arm telescopic mechanism, a mechanical claw opening and closing mechanism, a rotary mechanism and a linear motion mechanism for loading and unloading tools.
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.
This article briefly introduces the application example of sensorless square wave drive in "small water pump" based on MM32SPIN05TW.
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.
All flight control information is provided to buyers in the form of data packages, providing flight control development environment, various drivers, various STM32 chip information, all sensor information, flight control related knowledge information, etc., as well as anonymous flight control source code, communication Board source code, etc., the open source code is a complete set of projects, and buyers can directly compile and download it after getting it. Using our materials, you can easily get started with flight control learning and learn the structure and ideas of flight control engineering. After having a certain understanding of flight control, buyers can easily transplant the flight control program into their own system, or add the functions you need.
