Battery Battery powered Rotating Beacon

[dquake]

Hello
Hope everyone is well and thanks for creating this forum.

I'm looking for some help for a project I'm doing.
It's a Short Film where I would like a red rotating beacon to cast its light on a solider running in a bunker's corridor.

I found a rotating beacon that comes with a car plug


How can I convert this to battery powered (like AA or similar maybe? or a small lead battery?) and hang it off a wall without having it to look like it's extruding too much due to the battery size?

Thanks a lot for any advice

Was it @davesparks who worked on the Dr Who time machine room thingy-me-bob? (sorrrrry to Dr Who fans, I should know the name of that, I don't watch it though!)

That has a million flashing lights and things. He might even have some left over?

Hey @Dan

I think I will be able to share a private link to the video as festival not always requires a "single-use" screening. Not commissioned (I wish!), just a hobby

Hope I can get it done though!


I had a look a look around. The housing for 8x AA batteries only have two cables, red and black. I'm thinking to cut the beacon's car plug and see the wiring inside or buy a converter from car-female to red+black (actually used to jump start the cars)

Not sure about voltage/watts though. I'll try to get the beacon's manual

@Zerax never too safe, thanks for the warnings. I go as far as fitting a PSU in a PC so any help is appreciated

Connect the red wire from the battery pack to the wire that goes to the centre pin of the car dc plug. And the black wire to the other one.

I'm not guilty of that one, all my entertainment industrt work has been in theatre and live events rather than any film or TV work.

And its a TARDIS (Time And Relative Dimension In Space)

Thanks will do.

Hi everyone!

So I managed to do it, but it's rotating really slow (see video here)

It's a 8x AA to power a 12V H1 lamp.
The instruction on the beacon says I can change the internal engine belt to 24V.
If I daisy-chain the batteries packs, like 2x 8xAA, will it go faster?
Can I daisy chain 3x to feed power into it? Will the lamp blow?
(Manual says 18V to 34V for 24V fitting) Should do up to 180rpm
