Ejector Arm

A project log for Interactive Mario Mushroom Block

Ever want to punch a mario block and get a mushroom to come out? Me too, so I'm building it.

Still waiting on the mario mushroom plush to arrive in the mail, but figured I'd build up the ejector servo. Using more brass tubing, I fashioned a armature capable of ejecting a small item.

Things are starting to get busy in there. Oh, and did you notice the new speaker? I accidentally drilled through it when adding in the white slider rails to the block. Whoops.

I made a new opening arm that took up less space. There is a problem with using two servos though, the library I used could only run one servo at a time. After the lid would open, I would switch over to the ejector, and the lid would fall shut as power was removed from it temporarily. I was able to easily solve this with a strip of duct tape for extra grip on the roof of the block tin.

And here is the demo. Getting very close to finishing this bad boy off.
