I spent a significant part of college tearing toys apart. When I got to Singapore, my 3rd auntie hinted that she could probably use my help in modifying some toys so that her clients (disabled children and elderly folks) could play with them. As it turns out, most of the toys that get them really excited have flashing lights and 1 motor attached to many gearboxes, and they only have an on-off switch. The issue is that for most of these disabled children, they are not able to play with these toys because they don't have the mobility to turn them on and place them on the floor. So my role was to wire an additional switch to go in parallel so that the user could control the toy from a distance (and also so that if it was a moving toy, it wouldn't run away from them).
