Based on the portable soldering iron open source system IronOS, download the full set of open source materials for Pinecil V1 (software, hardware, etc.)

The portable soldering iron launched by PINE64 in the early days was based on the GD32 design. This time it was upgraded to the second generation product, which was changed to the domestically produced BL706. Its feature is that it supports low-power Bluetooth. The Bluetooth OTA upgrade function will be added to IronOS later. IronOS supports a variety of portable DC, QC, and PD powered soldering irons, and supports all standard functions of smart soldering irons.

Zhihuijun's new work: Hanwen smart keyboard with FOC force feedback knob, multi-function, modular mechanical keyboard (schematic, firmware, etc.)

The keyboard uses a modular design. The multi-functional scene interaction module on the left can be replaced with various custom components. By default, a Dynamic component with an e-ink screen and FOC force feedback knob is used; the keyboard body uses a shift register method to implement the key scanning circuit; The module and keyboard body can be used alone, or they can communicate and call each other through the serial port protocol.

CANT: CAN bus simulation implementation

There are many I/O methods that simulate UART, SPI, and I2C protocols, but there are very few that simulate CAN protocols. The CANT introduced today is a CAN bus simulation implementation. The original project was demonstrated on the ST Micro Nucleo-H743ZI board. The author recently launched a C and Python package - canhack, which facilitates porting to various chips without CAN.

Implementing ultra-low-cost dual fiber optic network card 100BASE-FX based on Raspberry Pi microcontroller (open source software and hardware)

The Raspberry Pi microcontroller itself does not have an Ethernet MAC, but it can be easily implemented through the programmable IO of the Raspberry Pi. The programmable PIO of the Raspberry Pi microcontroller that costs 5 yuan a piece is indeed a miracle, with IO below 250MHz. Control everything.

Schematic PCB

Based on the 5 yuan Raspberry Pi RP2040, 24-channel 100Msps logic analyzer open source project

The hardware is independently completed by the Raspberry Pi microcontroller RP2040, which costs 5 yuan a piece. Just close a trigger design baseboard designed by KiCAD. The software is created using VSCode + GCC + Cmake. It doesn’t matter if you don’t know how to use it. The firmware is upgraded using the U disk drag-and-drop method that comes with the Raspberry Pi chip.

Wigl Kit: Create your own music-loving robot (including schematics, source code, etc.)

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.
