Looking for some sort of actuator...

[northwind]

Not really sure what would fit the bill here... It's got to be fairly small and light- couple of fag packets at most- 12V, and able to pull a cable about an inch, either with a lateral pull or a rotation. Doesn't need to be particularily strong, though. Cheap is good ;) Someone suggested an EXUP actuator but I think that might be too big?

look at stepper motors that you find in RC cars etc..

[Sid Squid]

Or an RC model servo, very torquey, very small, throw depends on lever geometry, you'd get an inch pull easily

[BILLY]

Are you making a flip up number plate :twisted:

[Reckless Rat]

Not sure what sort of actuation you need, but wouldn't something from a car central locking system do? Door or boot release....

Thanks folks, looks like a stepper might be the simplest option... Servos look like more trouble to control? And bear in mind who you're talking to here, simple is the number one goal ;)

[CoolGirl]

um, I have no idea what you're talking about. *glazes over in a cazza-like fashion*

I'll go and busy myself elsewhere.... :oops:

Then probably a servo is better from an RC car than a stepper motor which needs some logic control i think.

I've got an brand new exhaust valve actuator from a GSXR600K6.

It's about the size of a fag packet. Comes with the necessary push and pull cables as well.

Make me an offer.

Maplin do central locking motors.. move about an inch? Cost a tenner for a 5watt.

That's on the right lines actually. I might pop into Maplins and see how that'd work. It's certainly closer to the intender purpose anyway ;) Dones't need a brain either, that I can see.

Thanks again folks.

[Warren]

so what you need it for ?

im intrigued.

[northwind]

It is a Sekrit I never say what I'm doing unless I know it's going to work ;)

[John Burt]

I know what it is - your going to use the actuator to depress the centre pin in acan of butane straight into the exhaust -flames on demand




DO NOT TRY THIS AT HOME :wink:

[northwind]

Yes, I am, now :) Make that 2 central locking motors :)

He's putting a rear spoiler on his bike which rises when he reaches 70mph... Porche like... :wink:
