This project includes all the software and hardware design required to develop the T12 soldering station. The PID parameters are mature and the function completion is very high.
Mega-Cube is a light cube that drives 4096 LEDs based on PL9823. The main control is Teensy4.0 based on NXP i.MXRT1060 FlexIO function and many 595 shift registers. It can control up to 32 channels, each channel 1000 LED.
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.
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.
The DS28E18 is an easy-to-use bridge integrated circuit (IC) that operates as a 1-Wire® slave device to a host controller.
The MAXREFDES1265 is a reference design showcasing the MAX7360 and MAX32625PICO with a low-cost, small-size keypad interface.
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.
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.
