Hey, I’m Copilot, your AI design assistant. I can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:

@copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?

@copilot How would I connect these parts to make the LED flash at 1kHz?

@copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.

Chat with me by tagging @copilot on comments or in the chat.

Battery Capacity: 1250 mAh • Wattage Range: 3.70 Wh • Resistance: 1.5 ohms • Chassis Material: polypropylene (PP) (if ABS (Acrylonitrile Butadiene Styrene) is required by the manufacturing process or supplier, we are open to using ABS as an alternative material for the chassis.) • Charging: none • Operation: The user inhales and triggers the air flow sensor which triggers the coil to fire, while the coil is firing, the hit timer will start from 20 seconds and count down only while the coil is firing. Once the hit timer equals zero the device will then start a two-hour countdown and if the user tries to inhale through the device while the two-hour countdown is going then the LED indicator will only blink and the coil will not fire. Once the two-hour timer reaches zero then the hit timer will reset to 20 seconds and the process will cycle like this until the battery dies. • LCD screen display: The LCD screen will constantly display the juice amount left in the corner and the main part of the screen will display the hit timer until the hit timer equals zero then it will display the two-hour countdown. Once the two-hour countdown reaches zero, the main display will change back to the hit timer. The Screen will only turn on once hit and only remain on for 5 seconds after the device is hit. • Pod Series: none

From your description, it sounds like you're designing a vape device with specific operational parameters and features. Let's break down your requirements and how they might be achieved with electronic components:

Key Components and Considerations

Battery Management:
- Battery Capacity: 1250 mAh
- Battery should have protection circuitry to prevent over-discharge, short circuits, etc.
- Charging: No charging is needed as per your design, so the battery should be connected through a removable mechanism for easy replacement.

Coil Firing:
- Resistance: 1.5 ohms
- You’ll need a MOSFET or a relay capable of handling the current to activate the coil.
- A control circuit to handle signals from the air flow sensor and control the MOSFET/relay.

User Interface:
- Air flow sensor: To detect user inhales and start the process.
- Hit Timer and Countdown Timer: This logic can be handled by a microcontroller (MCU). You might consider using a low-power MCU to manage power consumption.
- LCD Screen Display: A small LCD or OLED screen can display the timer and juice left. Perhaps consider an I2C or SPI interface for the display.

LED Indicator:
- Consider using an RGB LED to indicate different statuses: ready, countdown, etc.

Chassis Material:
- PP or ABS plastic are both viable materials. Ensure your design considers the heat produced by the coil and any safety regulations.

Power Consumption:
- Since this device relies on battery power, optimizing for low power consumption is crucial. Ensure components like MCUs, sensors, and displays are low power and include sleep modes where applicable.

Suggested Circuit Connections

Here is a generic outline of how components could be connected:

Power Supply
- Connect BAT1:POSITIVE to the power input of your MCU and coil circuit.
- Connect BAT1:NEGATIVE to ground.

Coil Activation
- Connect air flow sensor output to an MCU pin configured to detect state changes.
- MCU: Output a signal to control the gate/source of a MOSFET that activates the coil.

LCD Display
- Connect the LCD via I2C or SPI to the MCU. Use dedicated SDA and SCL lines if using I2C.

LED Indicators
- Use MCU GPIOs to drive the RGB LED.

Hit Timer and Countdown
- Implement the timer logic in firmware, using MCU timers.

Enclosure Considerations
- Ensure the design allows airflow for proper sensor operation without exposing internal components.

If you need specific components or further clarification on parts or connections, feel free to ask!
