Hi, is there anybody out there who knows where <BR>i could get schematics to build a siren (i've done <BR>it once with my guitar distortion and it worked out pretty well)... <BR>Jah !

try craig andertons book ' electronic projects for musicians' , it might have something , but its been a while since i read it...

actually i'll just contradict myself , seeing as a siren is a basic synth and not an fx processor it probably wont be in that book , but if you know a bit about soldering etc it shouldnt be too hard to make. its a typical VCO>VCA + LFO set up , and isnt too hard to make , but given that you could build a decent synth with not a lot more you're probably better off doing so , unless of course you want siren sounds only .

I was recently thinking about building a siren myself. I searched the net for instructions but didn't find anything you could use "as is". There are quite a lot of sites around with schematics for synthesizers. But I think these schematics are oversophisticated as they feature temperature compensation which is not necessary for a dub siren. (A siren doesn't have to be in tune..) <BR>I came across some basic schematics which may be useful as a starting point for experiments: <BR> <BR>- <A HREF="http://www.interruptor.ch/images/oscillator.jpg">basic
audio frequency oscillator</A> <BR> <BR>The next two schematics are taken from a electronics experimentation kit for kids <BR>("Tonhohe" means pitch or frequency, "Lautstärke" means Volume, The "NF-Modul" is a amplifier module that can be used to connect the circuit directly to a speaker. You don't need this since you already have a sound system I guess ;-) <BR> <BR>- <A HREF="http://www.interruptor.ch/images/Tunable.jpg">tunable
oscillator</A> <BR> <BR>- <A HREF="http://www.interruptor.ch/images/siren.jpg">simple
siren</A> - press and release the interrupter "Ta" to let the siren pitch increase and decrease. <BR> <BR>I ended up buying a second hand dj-sampler which allows me to use some dancehall-style samples too. So my investigations on how to build a siren ended after that... <BR> <BR>If you decide to build your own siren it would be very interesting to know about the circuit you are using for publishing it here. <BR> <BR>hope to hear from you again! <BR> <BR>Big Up <BR>Daniel aka The Interruptor

i'll take the notes here and try to do something about them - thanks for the time being .... <BR>I'll report when (and if) i succeed :-)

hi, <BR> <BR><A HREF="http://www.interruptor.ch/sirenschematic.doc
" TARGET="_blank">this is a circuit diagram for a siren.</A> <BR>explications are in french. <BR> <BR>there is potentiometers for tone, frequency of oscillation and range of oscillation. <BR>you can modify it to change frequency of oscillation and tone. to do it, change c1 and (or) c2. <BR>you can add a switch selector to put different capacitors, so you will have different possibilities of frequencies. <BR> <BR>I just received this circuit, and I'm going to build it as soon as I can. actually in august, most of electronic shops are closed, so I wait september. <BR>I don't have any idea if it sounds goods, but it seems... <BR> <BR>munky lee

HI all ! <BR>i've built the Siren, it works very well, <BR>especially whn you run it through a massive <BR>delay... i'm gonna set up the soundsystem <BR>next friday afternoon on the beach and have <BR>the box with me, jah bless. <BR>If anyone here lives in Israel (which i guess you <BR>don't) contact me via e-mail for more details. <BR> <BR>BTW, anyone has more effect schematics ? <BR>Toby

Congratulations Toby! Did you use the schematic <BR>supplied by Munky Lee? It would be great if you <BR>could write a small documentation of your siren <BR>(maybe even with pics and realaudio-file). <BR>This would be a big help for other likeminded <BR>people! <BR> <BR>BigUp <BR>Daniel aka The Interruptor

Hi, <BR>Thanks for the encouragement... <BR>after the gig on the beach next <BR>friday i might sit down, write a few <BR>words, and might even add in some stuff for <BR>you to see/hear. <BR> <BR>much respect for Munky Lee & Daniel

so tobby, <BR>do you have some pictures, maybe mp3 of my siren I've never built???!!! <BR>the reason why : I actually save some money to buy the russ d. one. lucky me... <BR> <BR>mat (aka munky lee)
Posted: Thu Oct 25, 2001 10:12 am
Toby sent me a report/article about his <BR>siren and an mp3 file some days ago. <BR>I'll publish it here on this site as soon as I <BR>get the pictures he is preparing right now..

OK. Toby's report with mp3 file and pictures <BR>is now online at <BR><A HREF="http://www.interruptor.ch/dub_diysiren.shtml
> <BR> <BR>enjoy!

Hi all, <BR>first of all big up 2 Daniel for setting up this joint , a pretty unique place indeed <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif
" ALT=":)"> <BR> <BR>then I'd like 2 know your opinions on this small idea I've had: a square wave with adjustable frequency (say 0-or-so-to-300 Hz) , to trigger on & off the sounds from your deck ( from only one aux possibly , not the main out
) , which is again fed into maybe an echo unit.. <BR>The problem is that I'm not that sure on actually how to build this thing... vco>transistor ? <BR> <BR>I'll post again here (I'm planning 2 build the siren - thanks Mat for posting it <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif
" ALT=":)"> ),in the meanwhile shoutz go out to all the true dubheads.. <BR> <BR>Bless

y'all, <BR> <BR>i was curious what a "dub siren" was, but it turns out i had already made one on the cheap out of a "magical musical stick", one of those dollar store keyboard sticks. take it apart, pull out the small circuit, snip the pitch resistor and solder in a 500k-ohm potentiometer in series with it, for siren sounds you can pitch down to a fat rumble. solder a switch between the 2 membrane contacts, and you've got a siren. maybe costs about $10, and would take about an hour to make and recase. <BR> <BR>i've got mine wired into one of those halloween voicechanger toys, for tone variation. nice, cheap 'n dirty.

Greetings, i wanna know if somebody can give me a schematicpln like this. <BR><A HREF="http://www.interruptor.ch/images/siren.jpg
> <BR> <BR>For the dub sirene from munky lee? <BR>It would be very nice, me have a little pit problems to read his schematic plan. <BR>It would it be nice if you can send me thi with a list of all Pieces that im need. <BR>Can some body do that please? <BR>Me overstand english an the german language. <BR> <BR> <BR>Give thanks foryour help <BR> <BR>Ras Nibru <BR> <BR>Jah Love

I was just wondering how low that siren can be tuned...?

I have just constructed a dubsiren from the circuit posted on this site. <BR> <BR>It works fine, except if you keep your finger on the button for more than about 20 seconds the signal breaks up and gets nastily, speaker rippingly loud. <BR> <BR>Any suggestions to what is going on. I am running it from a 9v battery.

Yo yo <BR> <BR>There is a new manufacture of dub sirens. <BR>You should check out this link - <A HREF="http://www.no1derland.com/Sounds/Sounds.htm
> <BR>They have also bunch of other stuff like theramines etc.
