Remote pole raiser? Answered

Need to raise a 10 lbs, 30" pole from horizontal to vertical with one click and back with click. Very basic one direction car wiper or human elbow movement. It does not matter the mechanism used: motors, gears, springs and mechanical or electric locks as long as it is reliable and cheap. The mechanism plus transmitter, battery and charger cannot exceed $90. Used to raise and lower a sign.

You can get a linear actuator and a controller strong enough and in your price zone at Amazon.

Linear actuators the best but expensive for $90 total budget incl remote, receiver, battery, charger. Lowered weight using 30" 1"D PVC or Alum. Counterweight ideal might be helped by film of heavy oil in tube that would flow to bottom when being raised. Pending issue:activation. If motor, how do I determine specs? If springs, how to change from raise and lower remotely. Maybe I could use an electric protruding lock. When going out it slides over the round pipe and makes it move up. When retracting it goes down. It might no even need gears to controlmovement

Make one - Threaded rod and a motor - How hard can it be.

Use a spindle motor shaft and string with click pins to steady the final position..

Oops 30" not 30 feet that puts it into the realm of LEGO so very easy to do a few gears and some rubber bands....

I assume this is a school or collage project. 30 inches sounds like a model so:

1. Counterweight to compensate for the pole weight.

2. Car wiper motor with up and down limit switches.

3. your not really giving all of the information - or enough. You talk of transmitter?

Is this to be radio controlled? What is the distance?

The illustration shows how to drive a DC motor up and down using relays in an H bridge setup

Now you need to do some work as well.

Calculate the force required to tilt the sign and go from there.
But I doubt you can do it at a budget unless you have most parts already at hand.

A counterbalance, as used on lifting barriers, would dramatically reduce the power / force requirements.
