Whack a mole

Forum topic
By kavikakid

March 3, 2009

I'm requesting ideas on how to create a moving part.

 

How would I create the same mechanism that the game Whack A Mole would use to RAISE and LOWER the moles.

 

Any suggestions would be greatly appreciated.

 

Also, if you know a great website for moving parts in general it would be helpful.

 

Thank in advanced!

The solenoid(s) described above can be obtained wicked cheap if you can use 12v... Go to any auto junk yard, they are used for power door locks.

*Update*

 

I think I have found exactly what I'm looking for.  the pneumatic actuators led me in the right direction.  However, since I require something small, my efforts have been focused on using magnetic actuators.

 

Here's my idea.  A magnet, copper coil, and a power source can be used together to create a horizontal movement of the magnet.  On the magnet is a CAM like solid piece that will create a vertical motion.  

 

I'm thinking magnets are the smallest way to go here.  Correct me if I'm wrong.

Hi, what about this...They are small 1.5 to 6 v solenoid actuators, some sprins and bars... maybe do the job.

Hi,

I am new here but I have a related question about solenoids.  If I have a set of solenoid actuators and I want to independently control each of their movements what kind of hard ware do I need?  Is this easily scalable as well?

 

Hope you can help.

My suggestion is to make a new thread in the forums to ask this. Give us as much detail as possible. You'll get more responces that way, as opposed to here in this cluttered old thread =)

Whacka.jpgTo imitate a pneumatic ram then possibly a cam shaft with a small suspension spring from a model car could work.
