sparky/gadget whizzes.. little help pls?

[bugjuice]

Can I help you? I'm Beanman!! so no.. however...
sorry, I read that title, and that's all I can think of at the moment..

anyway, on-topic - gots me an idea. But I'm not quite in the right mindset about a few bits (cos my mind is filled with other stuff).

What I want is a push button. That runs a wee tiny motor (what's the strongest smallest motor available? without spending my annual salary), for a set period of say, 5 seconds (time will depend on how fast the motor spins etc)..?

any clues on how I can do it?? I have an idea for something, but I just want to see if the electrics are easy enough to sus before I start fabricating stuff (and by 'fabricating', I mean bodging)

ta all, love ya work

The servos used to adjust the shocks on jap import cars are smallish, about 60 mm diameter and 10 mm thick.
Going to 'adjust' your number plate remotely?

You want to change something from one position to the next?

If it were to move a plate like device from one pos to another then you could use a servo from a modelcrafts shop ie like a remote control plane...

It'll be no problem to make a push button trip a relay for a set period of time (eg 5 secs) using a 555 timer.

I had a dog, and it's name was...........



I have fabricated a design in mind which should look quite 'trick' when it's finished, that's if I can finalise it in my nuggin, then in a template. Should be good. Just need the electrics to work right.

Had thought about a servo from a radio set (having played with stuff like that before), but I don't know if it'd have the length/range I need, and strength for it's size. Might..

The motor bit isn't the biggest problem. It's the timing of it (relay?), and making it go one way with a push, then the other way with another push

[skelstar]

What about a solenoid? Just apply 12VDC to it and it moves in. Unless you want a 'trick' sci-fi movie like feature a plain old cetral locking mechanism would be good. hide it away under the seat with an arm coming out to the 'thing you want to move'...

[bugjuice]

solenoid? how big are they? (brain fart, please excuse)
I'm wanting to keep it tiny, neat, small, light and tidy, and most importantly - avoid the option of cutting into the tail to fit stuff.. So it's ideally gonna be fairly small. It'll be housed too, but damp could be an issue

You need to give more info bug if you want to the do some lift and hold thing then maybe you should have the motor lift it and once it gets to the top a magnet pulls a hook towards the lets say plate which then turn the power off to the motor and when you turn the swith to the off position it lets go of the magnet which then lets go of the plate.

the motor is going to just wind the plate back. Mechanically, it'll fold and hold (set it, and forget it!!!)
the motor won't have too much to strain about (hopefully)

[enigma51]

Just a note but im sure you have though about it already. You want it to swing backwards so that the number are showing up. The wind will help the motor out ie less work for the motor.

What about the motor and setup out of a car with pop-up headlights? Could be pretty cheap from a wreckers out of an old integra or something similar.... not sure of the size tho.

what he said, they are fairly simple to use as well which is always handy and cost bugger all

yeah, that's the idea. It's more out of design than force-help for the motor. It's just a bonus. And, it won't be swinging

pop-up headlight mechanics are often huge. Way bigger than what I've got in mind, and can be a little heavy for some. Plus, it'd mean either a fair bit of cutting around the tail (really not doing that) or some big ugle thing under the tail (ain't gonna be pretty), so altho it'd be a logical approach, it doesn't serve what I'm after.. thanx for the input tho

Take a look here, this might be usefull. Not sure though...

what about making it go one way, then go the other on the next push?
