Brief: To create a handheld device for an underserved target group
We created a device for London Underground drivers that charges via stretching to produce a light for their journey. Check out my video detailing our design process and DayLite's use:
In this group project, I was in charge of:
- Research and performance requirements (test rig set up)
- Organising meetings with TFL staff
- Electronics design and manufacture with Arduino coding
- Filming and video editing

The test jig was an early prototype to test out the basic functions of mechanics and electronics. Here I used workshop materials and equipment to build up the jig to collect the approximate generated power from a measured amount of pulling force.

DayLite really stretched me in a lot of different subject areas whether electronics design, manufacturing or sourcing research participants. I am glad to have received the constructive user feedback throughout the project as this is what makes the design worth it. Also I will not forget shooting videos on the night tube at 3 am with my team mate.
