 | | Help please: I'm trying to get two outputs from one shaft —Tony Hafner
|
| | | I have one shaft that will be turned by a motor in either direction. And I want to get two different outputs, based on which direction the motor is turning.

| | | | (...) Hi Tony, Here is something I put together real fast during my lunch break: (URL) The movies are quite big (4MB a piece) but they show clearly how this thing works... Notice that it works in any position as the mechanism is balanced. An other (...) (19 years ago, 27-Sep-05, to lugnet.technic)

I was a little worried at a few stages of construction when the 1x4 brick sometimes would rotate until it wasn't engaging either gear and then sit there with the 8t gears spinning freely- but in the full (...)
