remote actuator to move lens

[kgveteran]

I've assembled a Constant Image Height front projection system and need help finishing the last part of the project.

I have a prism based lens that expands a verticlly stretched image for this system.The lens is mounted to a sled that slides the lens into the path of the light and slides back if not needed. I have found some actuators on line and need some help on assembling a remote control actuator that will move the lens back and forth via IR commands or triggers. The weight of the lens is minimal as it is supported by the sled. It will only move about 6" to be out of the way of the light path.

I'm not sure where to start.Thanx

KG, have you thought of using the IR control system out of an old CD player that would have the eject and close feature? Everything you need would be there to control the start and stop, you would just need to tell it when it needs to stop by micro switches or a timing device.

after a little thought, you may be able to skip the actuator all together and just use the motor assm from the transport mechanism.....

I like it ! Do you think it would be hard to single out the circuit that controls the drawer.This is very exciting.

So, the circuit would reverse the polarity on the little DC motor that drives the drawer.Icould use relays to bump up the ability to handle higher voltage and current.

Now, i need a junk CD player....hehehehe :B ...with a good drawer circuit

I dont think that it would be hard to take the circuit out, if you can find and older Rotel, like a 955AX, they have mechs that are built like tanks and are made of metal.

KG,

You ever get that project going? would like to see some pics if you have them.
