Want simple strobe circuit

M

Guest
Good Folk,

I'm looking for a simple strobe circuit for a fairly high powered strobe
light to flash once or twice a second to be used as a beacon. I can find a
number of circuits, but they all use mains input, and I want to run this one
from a 12V car battery.

Any pointers much appreciated.

Mike.

In case you decide you can use less than a "fairly high powered" strobe,
<www.allelectronics.com>
They have complete, ready to run, 12vdc 150 ms strobes for $8.95
120 flashes/minute
Your choice of red, green, blue,amber, or clear lens
 
Thanks very much, I had a look, and the unit looks interesting - in fact,
being waterproof (weatherproof) makes it something especially to consider. I
think I'll get one and see, but I really did want something bright, so if
anybody else has further information on a more powerful unit, it would be
most appreciated.

The same shop is selling a variable flash rate unit, but they say from evert
two to three seconds, and there again, I wanted a faster rate. Do you know
what power light it uses? The description doesn't say.

Thanks again,

Mike.

Sorry. All I know about those strobes is what I posted, taken from the
catalog. Coincidentaly I was looking at the catalog early this week,
remembered seeing the strobes when I read your post. Even a tiny strobe
is eye-catching in the dark, even from a mile or more away. I had
first-hand experience with USAF survival strobes many years ago, and the
tubes in those are small. Maybe you don't actually need a huge tube?

I'm thinking about getting one of the All ELectronics strobes (clear
lens). If it's not blindingly bright I'll put it on the front of my
bicycle.
 
Thanks again, Michael,

As I said, I'll get one and have a look. If it isn't bright enough for what
I want (visibility from around 10 miles), then I won't have lost enough to
cry over. Worth a shot!

Regards,

Mike.

How 'bout giving us a review after you've torn into it?
 
Well, I tried to order the strobe, but it didn't work because I was ordering
it from England, and the only countries they mail to are the USA, Mexico and
Canada. What a bum rap!

I'll repost the request for a circuit and see what interest I can raise.

Thanks for your help, though,

Mike.

Here is one circuit example:
http://www.epanorama.net/circuits/strobo_12v.html

In the highest setting it could just do 2 flashes per second
at highest power setting that was as brigt as one flash
made by the flash unit of those disposable cameras.
Actually the circuit uses parts from such camera
(flash tube, main capacitor and trigger transformer).

This circuit is triggered from some external triggering source
(so you send pulses to trigger input at the rate you want this
to flash).


Other links that coul be useful are:

Stroboscope controller (works with above circuit)
http://www.epanorama.net/circuits/strobocontrol.html

Thanks very much, Michael.

In fact, I think I have found what I was looking for. I'm busy building it.

There is a pretty good 12 volt strobe project on my site that may be
useful for you.
A lot of these cheap strobes, for sale on the web are just that.
"CHEAP, made with surplus parts"!

Anyway if your interested, have a look at:
