ESC is the abbreviation of Electric Speed Controller, that is, electronic speed controller, or ESC for short. The author is Benjamin Vedder, so it is called VESC. You may have heard of it, which is Benjamin ESC. This project is mainly divided into several parts, VESC firmware, bill of materials, VESC hardware, and VESC tool software. It is a very complete software and hardware project, and the supporting software is also excellent.
A low-cost PD-powered reflow soldering heating plate that uses a cermet heater (MCH) instead of a PCB heating plate for heating. It has a USB Type-C input port and can be powered by a 60W (65W) PD power supply.
The cost of the board should be less than 50RMB, and it provides a lot of information, which is very suitable for novices to use as a development board to learn Linux.
There are three boards in total, USB, FPGA and Sensor board. The FPGA board features a Lattice Crosslink NX LIFCL-40 and the required power regulator, and the USB board features a CYUSB3014 USB 3.0 SuperSpeed controller.
This open source ferry robot has unique functions such as the anti-interference standing ability of a tumbler and automatic roll-up.
SmartKnob is an open source input device with software-configurable stops and virtual locators. The brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, allowing the feel of the detent and stop to be dynamically created and adjusted.
ScopeFun is an open source all-in-one instrumentation platform. It includes oscilloscopes, arbitrary waveform generators, spectrum analyzers, logic analyzers and digital pattern generators.
Bllimpduino 2 is a very low cost open source autonomous airship. It consists of Arduino M0 airship controller board and on-board WIFI and laser sensors. Two vector differential thrusters and one lift thruster. The design is simple, yet exciting.
This 100 W reference design highlights the excellent power quality and high frequency performance of the half-bridge (HB) driver using the ICL5102 with the economical CoolMOS™ P7 series. The design takes full advantage of the applicable frequency range of the HB driver to create Highly compact LCC transformer. This transformer integrates the series inductance of the LCC resonant tank. Relying on this high power density transformer design, the high frequency operation capability can drive system cost and size reduction.

With the in-depth research of ultrasonic levitation technology by domestic and foreign scholars, ultrasonic levitation devices have developed from expensive horns and other equipment to structures composed of general-purpose commercial ultrasonic transducers. Combined with 3D model printing technology, any scientific researcher and Electronics enthusiasts can use these components to make ultrasonic levitation devices to facilitate related acoustic research. This technology was published in AIP Publishing by Asier Marzo et al. Based on its model, this design changes the main control MCU, uses the timer inside the MCU to generate accurate PWM waves, and improves the software so that the ultrasonic device can move the suspension stably during the axial suspension movement. Small objects in multiple nodes.
The author opens up the schematic diagram and supporting Raspberry Pi code. The simulation bandwidth is already 30MHz, and the frequency response is very close to the theoretical simulation, with a difference of about 0.02dB between 1kHz and 30MHz.
Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.
Ideal for running network devices such as small switches, home routers, and WLAN access points.
