The Ecto-1 Siren physical unit is real. However, the sound is not. This was 100% Synthesized. There used to be a You Tube video of them actually creating the sound with a Guitar and Keyboard. Then guys spending time actually adjusting the pitches. I have yet to find a really high quality recording (the original would be best). I want to play it through my Code 3 Mastercom 100W Siren. :)

The siren from the original Ecto 1 was produced by Federal Signal for a few years. Unfortunately it is very hard to come by.

I believe that the Ecto-1 siren never was real - it was added afterwards, purely as an effect, and not possible with a "normal" siren. Wire up an mp3 player to a bull-horn, though...

So, are you saying that using a 555, we would have difficulty (at best) recreating it? Lots of different noises can be coaxed from that little ic :-)

Not a clue. I was quoting from memory one of the sites I looked at when I was looking for that clip. Do you have an image of the circuit you can use? I think I have a 555 lurking in the shed.

I am still "cleaning up"....half my diagrams are missing. I will add that to the list of those I am looking for..... And I promise it will not look like a Bob Pease breadboard (Bob Pease was a "distant" mentor in a sense as I was growing up):

In case the name was obscure:

Bob Pease of National SemiConductor

And

Bob Pease of Electronic Design ( of Pease Porridge fame)

Pease started work in the early 1960s at George A. Philbrick Researches (GAP-R). GAP-R pioneered the first reasonable-cost, mass-produced op amp: the K2-W. At GAP-R, Pease developed many high-performance op amps, built with discrete solid-state components.

He is the author of eight books. Here it the link and article concerning the Breadboard picture

His now famous image below:

Yikes, I thought it was a deliberate mess, purely for the photo! Imagine the mind that can follow that maze to look for the one dry joint or threaded solder...

Yeah, I learned a lot from his articles, one of those things was NOT how to be organized. There was a story that his boss once asked him to clean up his office, which had stacks and stacks of manuals and papers everywhere. When Bob asked what the boss had actually come for, the boss asked for a certain file....Bob paused a moment then reached into the pile and pulled it out. The boss never bothered him about his "organizational methods" again :-)

Either of these two should handle it.

You can change the values of the left hand side resistors and capacitor to make dufferent pulse lengths.

I saw that (or a similar reproduction) parked outside Wembley Arena for the play.com games expo.. I'm annoyed I didn't get a photo now but they said no cameras were allowed so I didn't take mine :( but I believe a friend I went with has a picture of himself standing next to it :)
