Still need to get to the individual for some user testing, likely will have an iteration or two infront of us.
Had a couple Gr 10/11 Mechatronic students with me, so they took it on as a project. They have actually done a ton of work for me getting prep done for 4 events in 5 days, so yay and cheers to fun smart kids looking for meaningful work experience. They will be helping me at a build event today and the big one on Tuesday to boot.
