With a focus on safety, this portable device enables outdoor goers to actively eliminate attacking mosquitoes without employing chemicals and high voltages. When targeted, mosquitoes are guided by the generated airflow into a sticky collection chamber, which can be ejected to clean out the captured insects.

As somewhat of a hybrid between an industrial designer and design engineer, Hoyin strives to create beautiful forms and is guided by his curiosity in intricate mechanisms. With experience in designing and CAD modelling complex surfaces and production-ready parts, he is confident to take on projects that are aesthetically-focused or technical in nature. Hoyin is always eager to develop new skills in a team to advance their creative endeavours.
