I have finally been able to complete a final prototype for my bike light come laser bubble projector!
The prototype would attach to the seat stays, where it would be suspended above the rear wheel. Being in this position, it would be clearly visible to other road users as well as allowing the laser beam to project on to the road clearly!
I have designed a lockable hinge to hold the arms at different angles. The user would move the device to the correct angle and then tighten the hinge with a simple thumb screw.
The problems I have been identifying are mainly the problem of the hinges holding the arms have a tendency to slip and then the device falls onto the wheel, but this is something I hope could be fixed quite easily…
