In the open source electromyography project shared here, the author used this product to create a computer game control effect.
The Sensor Watch is unlike most smartwatches.
Little Bee is an affordable, high-performance current probe and magnetic field probe that allows you to debug and analyze electronic devices more efficiently.
The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.
All information is fully open, and there is also a mobile APP, and the algorithm is also made public.
The goal of PSLab is to create an open source hardware device (with all resources fully open) that can be used by electronics enthusiasts to do experiments. And offers a range of sensors for engineering experiments, including oscilloscopes, waveform generators, frequency counters, programmable voltage, current sources and data loggers.
STMBL is an open source servo driver designed for CNC machine tools and robot modifications. It supports industrial AC and DC servos up to 320V and 2kW.
Hardware configuration: Dialog Semiconductor DA14683 for master control, with BLE5.0
The schematic diagram is open source, you can see if there is anything worth learning from. This baseboard is designed for their previously launched H7 core board.
Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
The product design is open source and very cool and beautiful.
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.
ST has previously launched a board with a static current measurement range of 1nA - 100mA and a dynamic current measurement range of 100nA - 50mA, but it is not open source. This time it’s open source.
The very early model was a bit crude.
The schematic is in the appendix at the end of the document.
The most interesting part is the problem of energy collection without batteries. Currently, it provides energy collection by clicking buttons and solar energy collection. Ambiq Apollo3 for main control.
Hardware design is difficult, but Nordic is all open source, and PCB, BOM, Gerber, schematics, etc. are all provided. The schematic is also annotated.
