On the electronics side, we noticed that the voltage varies when using a battery since it does not have a voltage regulator. We tried to use the voltage regulator from the boost converter but found it problematic, so we used a voltage regulator from a powerbank instead. We found that the powerbank and mains worked well thanks to the voltage regulator. 

We also noticed that the driverboard has already been adjusted to control the atomisers by modifying the voltage supplied to them, hence there was no need for manual button pressing. 

We considered what type of switch we required for fan speed settings. We decided not to do three-way switches for different fan speed settings and instead just have one ON/OFF switch with speed control for simplicity.

We plan to do a round of crocodile clipping, before proceeding to solder the electronic components together. We will also test out the latest 3D printed bottle, and redesign it based on new changes required.
