[Spark Project - Bounty Track] MINI Heating Platform - AtomHeat

MINI Heating Platform - AtomHeat
Project Introduction:


This project is a small heating platform based on the LCSC Skystar development board - GD32F407VET6 - Youth Edition.


It supports power supply via Type-C interface and 5.5*2.5 DC interface. The Type-C interface supports up to 100W PD protocol, and the DC interface supports 16.5V-25.5V voltage.


Quick Link:


LCSC


Open Source Hardware Platform.


Function Description:


Powered by either Type-C or DC interface. Theoretically operating voltage is 16.5V-25.5V, compatible with 5-6 series lithium batteries. Actual testing only used 100W PD power supply.


Built-in accelerometer and buzzer; heating stops and an alarm sounds when the platform is tilted.


Five touch buttons and a rotary encoder allow for setting time-sharing and segmented heating. Five quick temperature presets can be stored.


A 1.8-inch TFT LCD displays heating power, current temperature, and heating curve. The hardware architecture project BOM


(Bill of
Materials ) is located under `/production_doc`, and includes: `BOM_Board1_V0.3_Schematic1_V0.3_2024-08-13.xlsx` and `BOM_Board2_V0.2_Schematic2_V0.2_2024-08-13.xlsx` . 3D printing shell files are located under `/production_doc/3d_print`. CNC manufacturing files are under `/production_doc/cnc`. Panel manufacturing files are under `/production_doc/panel`. PCB manufacturing files are under `/production_doc/pcb`. Other hardware is detailed in `/production_doc/other.xlsx`, which provides information on purchasing options. The software architecture is developed using EIDE, and the source code is located under `/embed`. A detailed software description is available in the `readme` file in this directory. The compiled firmware has been uploaded as an attachment. There are multiple ways to flash the firmware; please refer to the LCSC development board documentation for detailed instructions. Safety Warning: The Type-C and DC interfaces do not have backflow prevention design. Do not use both the Type-C and DC interfaces simultaneously for power supply; otherwise, you will be responsible for the consequences. Please be careful when the heating platform is operating. Note: Heating control uses PWM to control the average power; the instantaneous power is approximately 120W or more. Even with the power limiting function, low-power chargers may still overload and restart (e.g., using a 67W charger with the maximum power limited to 60W). When the temperature reaches above 300 degrees Celsius, the heat dissipation power is close to the heating power, and the temperature rises very slowly. To meet the low-voltage and high-temperature requirements of the project, CNC machining was used, resulting in higher replication costs. Demo Video Links: 1.
