Writing the firmware will take a bit of time, writing code is not a particularly enjoyable task for me.

The next steps will be:

• Routing a PCB with a single sided load
• Routing a custom metal core PCB
• Ordering these boards from a board manufacturer
• Redesigning the button mechanism
• Adding the temperature feedback to both LED and Battery
• Overhauling the design of the whole body
• Writing a proper firmware
• Experimenting with reflow soldering the board
