Hello All,

I'm no stranger to electronics design and building. I'm exploring the idea of a Stuka Siren, going into a 1.8m span aircraft. Don't fancy shelling out £120 for one... anyone made one or want to share ideas?

Someone better aquainted to this site will come along shortly and fill in the gaps in my posting, but I seem to remember that a UK kit manufacturer making one that was mentioned a couple of months ago ?

Electronically Stevo, this is no way difficult to realise. The bug is the speaker, which by definition, has to be heavy to make enough noise, and be mounted on a noisy bit in the model.

Noise maker design comes in 2 forms for us. We can record and playback the siren.

Or noise generate the siren electronically. Do not pay £120 for one as we will root out diagrams.

An actual electronic siren is only £20, and a sound generator circuit chip, about £2.50

A club mate had a large scale Stuka and he had the siren system in the fixed in position center bomb.idea

Would this work?

Some suggestions thank you

The hardest part (as has been said) is the speaker. I was thinking some Piezo transducer type, as I'm hardly looking for HiFi!

Perhaps this... Arduino as an MP3 player, playing a continousy loop of the siren. When triggered from the Tx, it then turns up the volume (from 0) to a high level over a couple of seconds. When turned off from the Tx, it then turns it down, again over about 2 seconds.

Power amp? Fed from a lipo? Stereo power amplifier in bridged mono to give the voltage swing?

Spinal Tap? Turn the volume up to twelve and get thrown off the field. cool

A shop bought piezo siren is easily switched on and off electronically and is the economic route to take.

Indeed Denis... but does it sound like a Stuka..?

Difficult question. Not many about. And you would not get me to volunteer to stand under one to find out. But in fairness, neither would your potential critics. Why not just lie to them.

It's all in the ear Donald... I've sussed the sound, WAV player, amplifier... Just sourcing the Piezo driver

Arrrrrr, Stevo, me old lad, you may have a good ear, but was your fancy WAV recorded from under the thing. Think before answering.

I did think all this before I found the sound file. Recorded from under the aircraft, (i.e. ground level) you will hear the sound compressed... rise in pitch... and when it's out of the dive, the pitch lowers... OK.. Doppler effect.

After much searching. I found a sound file that is constant in pitch... so at least it sounds realistic when it flies past!

But doesn't the siren increase in pitch as the airspeed increases - or did they have a speed regulating mechanism?

devil's advocate...

Could you not ditch the electronics and make a whistle.

I seem to remember a build article in one of the magazines where the builder used the inners from a rape alarm!
