The ultimate tool for warm-hearted men: a sister product to the DC heating station "Warm-hearted Cup Holder".

The ultimate "warm guy" product!!! Give "her" a warm guy, and whether he can handle her is another story...

Due to the prolonged lockdown caused by the pandemic, several projects were progressing slowly, and unfortunately, I was unable to participate in the Spark Program. Although I cannot participate, I will continue to add projects later.
 
When migrating or modifying projects, please retain the source, logo, and platform information. For learning and communication purposes only, commercial use in any form is prohibited.
 
This project was  created out of  
the initial impulse: as the weather got colder, I was worried my wife wouldn't be able to drink water promptly at work, so I quickly modified it to pretend I'm a warm-hearted man ^_-
 
Technical exchange group: 754881030   
 
Disclaimer: High temperature danger! Electrical danger! Welding danger! Please wear a helmet when operating. Non-professionals should not attempt to clone or manufacture this product to avoid causing other dangers. Lichuang and I assume no responsibility for any physical injuries caused by any actions...

1. Mode switching (cooling or heating) Cooling mode is being adjusted.
2. Temperature setting (adjust setting temperature). 3.


Temperature calibration (correct temperature deviation).


4. Water drinking reminder (timed water drinking reminder).


5. Lighting setting (adjust mood).








6. Buzzer (reminder sound).
7. Restore default (restore default parameters).
8. IoT APP remote control (loading).
 

Button functions: (same as encoder)
1. Double-click the middle button to activate the menu, adjust left and right, click to save.
2. On the main page, click heating (cooling), click again to stop.
3. Long press, short press .
 
Update log for subsequent function additions:
December 8, 2022 1.1b
1. Added cup press limit switch (to determine if the cup has left or returned to its original position).
2. Changed the external temperature and humidity sensor from separate to independent .
3. The buzzer can be fitted with a vibrator.
4. Modified PCB appearance + adapted 3D shell. The appearance is more aggressive.
5. Adjusted to use a cheaper gate driver.
6. Maximum temperature limit 105℃; top screws changed to nylon + countersunk holes.
7. Reduced heating plate diameter; compatible housing.
 
Update Log:
November 25, 2022 1.1a
1. Fixed the issue of the water reminder not working.
2. Corrected the water reminder sound. Long tone changed to an alarm clock beep.
3. Added middle button to cancel and reset the water reminder.
4. Added water reminder.
 
 
Other details will be updated gradually.
 
Firmware download software can be found by referring to the heating platform (the only difference is choosing 8266 for burning).
Note: Since the PCB was drawn first and the schematic was drawn later, please leave a message if you find any problems. XX~~~~

sterilization and disinfection

Applications of UVA+UVC dual-band sterilization flashlights: disinfection, banknote verification, anti-counterfeiting, curing, jade inspection, etc.

The recurring mask shortage is disrupting normal life, leading to a renewed increase in demand for everyday epidemic prevention supplies like masks and alcohol. To control costs, a multi-functional, all-in-one sterilization flashlight has been invented.
 
Hazards: Never point it at any part of the human body or other living organisms, as UVC is very harmful. Short-term exposure can burn the skin, and prolonged or high-intensity exposure can cause skin cancer. Ultraviolet germicidal lamps use short-wave ultraviolet light; please use with caution. Lichuang and I are not responsible for any damage or loss caused by improper use.
 
 
 
Features:
1. Touch to turn on or off
2. Switch between UVA and UVC modes
3. Long touch for stepless dimming, linear brightness adjustment from 20% to 100%
4. Comprehensive charging and protection (red when fully charged, green when fully charged).

#7th LCSC Electronics Contest# MiniDSO (Simple Digital Storage Oscilloscope)

This is a project from the 2022 JLCPCB Summer Training Camp, a mini oscilloscope (MiniDSO) built using the National Technology N32G430C8L7 MCU.

Note: * Required fields,
please fill them in during the registration phase ↓
 
* 1. Project Function Introduction
This is a mini oscilloscope based on the National Technology N32G430C8L7 MCU. Key features include: small size, low cost, and simple operation, suitable for applications where size and cost are critical and signal measurement accuracy is not critical. Examples include: electronics DIY, student dormitories, and inspection and repair of outdoor electronic equipment.
The oscilloscope includes two signal input channels that can acquire and display two signals on an LCD screen for easy observation and comparison.
It also includes one signal output channel capable of generating sine waves, square waves, sawtooth waves, and triangle waves.
The oscilloscope uses pin headers to bring out power pins, which can be used to power other devices or as a breadboard power supply when needed. (The oscilloscope does not have a battery and requires USB power. A battery-powered version will be released later.)
 
*2. Project Attributes This is
a 2022 JLCPCB Summer Training Camp project, first release.
 
* 3. Open Source License:
MIT.
 
Please fill in the relevant information during the competition stage. ↓
 
* 4. Hardware:
MCU connects to power supply, crystal oscillator, LCD, user buttons, potentiometer, BOOT button, reset button, debug interface, and signal input/output interface.
The MCU collects and stores input signals, then displays them on the LCD screen.
Users can control the MCU's operating status using independent buttons and a dial potentiometer.
Detailed circuit diagrams can be found in the schematic.
A simplified circuit diagram is shown below:
The actual circuit diagram is shown below:
* 5. Software:
GUI section is shown below:
