[Robotgroup] Project Hand-Off

[brooksdesign]

I need the work but I'm stuck out here. I have a ruff design for a buzzer sewn into a seat pad that just drops into place and the cable drops down the side with either a connector or strung light christmas lights. Makes for a quick setup. Does that sound doable?
