Drop Arm Question

Hey I have a question about how to make a certain drop arm. What I would like to have happen is to emit something onto a platform made of two rectangular blocks. Once the object is emitted onto this platform, I'd like the two blocks to rotate inward "the left block going clockwise and the right going counter clockwise" so that the emitted object falls through the platform. Then I'd like for the two blocks to reset so that this can happen over and over again. How is this done?

well you can either synchronize the emitter and the chute so that lets say it emits a box every 4 seconds and the chute opens every 4 seconds, set the wobble bolts global synch to half (2.0) this way once the box is emitted the chute will open 2 seconds later and close right after, this will only work if your looking for a consistent flow of emitted objects like on factory line. If the emitting will triggered threw player action you will have to put either A: connect the trigger to the emitter AND a delay switch and connect that to the chute or B: put a mag key on the emitted object and a switch on the chute, make a delay switch so that once the chute senses the emitted object on it, it will have a short delay and then drop it.2010-06-16 22:12:00

If you have a magnetic key switch set to direction, and connected to the wobble bolts on the "blocks" / "arms", and then put a matching key on the object that will be emitted. When they key is in range of the key switch, the arms will rotate in the way you set them. Then, the block will drop through the arms, therefore putting the key out of the key switch's range - therefore causing the wobble bolts to return to their original states.

EDIT: I just ran your diagram through photoshop to try and explain what I mean...

Mag Key on the emitted object. Mag Switch near the center of the opening (perhaps at the end of one of the rectangular blocks). Wobble Bolts on the outer end of each of the doors. The Mag Switch is set to One-Shot and wired to an off-camera timer (use a block of DM [dark matter] connected via piston to a block of cardboard - Mag Key on one block, Mag Switch on the other [set to Directional] - piston set to Flipper-Out, with the Timing set to whatever time it takes to open the doors and close them). The timer's Mag Switch is connected to the Wobble Bolts. Now... either the object's emitter can be set to re-emit on a cycle based off the timing of this whole series of events, or another One-Shot Mag Switch can be triggered below the doors, as the object falls past.

Hope that made sense. All of it will have to be tweaked to your liking for the proper timing. And perhaps better brains will come and give a simpler solution, but that's how I'd do it.


EDIT: DayneOram's solution is much easier and does not require the use of the one-shot timer. You should probably go that way. I always over think stuff too much.

You could just use sprung bolts instead of wobble bolts. Use light materials for the doors and tweak the sprung bolts that they allow the doors to open when the emitted object falls through but can pull the doors closed afterwards. No need to use keyswitches this way.2010-06-16 22:33:00
