Advice needed: Car with removable top or bottom
Posted: Mon Jan 02, 2017 4:29 pm
Hey folks,
So my son's Pinewood Derby car is coming along. He got pretty excited when I showed him the 3D mockups that I wanted to recommend to him. We've gone and cut the chassis and have been testing electronics, but now we need to figure out how to put everything together.
What we'll have is the wooden chassis, a balsawood topper (hollowed out as much as possible -- also with a section removed to show the LED matrix) and a thin sheet of birch plywood as the underlayer. Somewhere inside of all of this is tungsten, the LED display, power pack, Arduino, etc...
I've attached a picture which shows a partially exploded diagram.
My question is this: How can we make it so that the car can easily be opened up to adjust components and charge the internal power pack? I think, ideally, I'd like for the underlayer to be anchored to the chassis, and the balsawood top somehow be able to detach...but perhaps this isn't terribly realistic? Another option might be to attach the components to the underlayer, and affix that to the chassis with small screws, that I could then remove as needed.
Suggestions or ideas?
