Hi.
Sorry for my horrible english.
I need some solenoids, but seems impossible to buy one... I just can't find it.
Where can I find solenoids? What kind of equipment have this?

electronicgoldmine.com had some a while back , check if they still have solenoids
what do you plan to use the solenoids for?

Hi.
In Brazil we don't have shops like solenoidcity.com, so... I need find something in old equipments.
I need one for a small cd changer project. I need to push/pull a small piece to force a pick to 'capture' one CD.
Here's a video of my needed: http://www.nautae.eti.br/solenoid_arm.wmv
Any better sugestion is welcome.
In fact, I really need a better idea...
I made two versions of a cd changer, but both using stepper motor to pick a CD. It's very heavy and turn unstable all the mechanical system.
Now I'm working on a new version, small and more simple.
Here's my OLD first version:

And here's a focus on the OLD pick:

just put a mini servo on it and have the arm of the servo turn and push down

Sorry, I didn't understand.
Is there some example?
Keep in mind that the arm is too small and must do a precise job.
Other, I can't use two motors at the same time (is a project problem). In other words, if I use the left/right movement (rotation motor), I must release the electricity of the pick motor, and it's must still given some 'pressure' on CD (using a coil or something like this).
