@dawnlighthours, I have a question.
I'm busy with my own projects at the moment, but I wonder if you would be able to design a motor and steering system for devices such as mobility scooters and electric wheelchairs. The wheelchair steering would need to use a toggle.
Bringing back these types of equipment is, in my opinion, a priority. Sure, we have standard wheelchairs, but not everyone can self-propell in them, especially those who lost limbs due to the stone eroding and cracking. We need to give back freedom.
If it's possible to make these systems reasonably straightforward to make, please do. That way we can produce a large amount of them.
