Upload NJD DUB SIREN CLONE Schematic&Diagram
It is Real NJD CLONE Schematic
Can make easy and low cost, under us$30 for circuit plus Enclosure
Have Fun Loud SIREN
Diagram has been updated 2/26 ver1.2

THX a lot for sharing!

Yo! ahahaha someone finally shared the most secret schematics of sound system culture!!! hey Yasuhiro! becarefuul some would kill ya for this!!! (kidding of course bro!)
any way, you directly cloned an original NJD? say so because i cloned the tubby’s and another french one who is supposed to be an exact clone, and it’s not the same shematics… it’s closed but not the same…
Peace.
Thanks!
I made a thousand or more units in 30 years
I was bored monkey SOUND SYSTEM business
And I think should be shared knowledge
A circuit diagram was cloned from NJD that had been owned by the old days
Other NJD clone are also almost same circuit
This circuit is very simple flip-flop Transistor circuit
I think that there is no copyright because it is a simple circuit, such as listed in electrical textbook
Please create a new siren based on this Schematic&Diagram
yes Bro,
i fully understand and agree when you say « monkey sound system byzness »…
and be sure that when i have a little time i’ll build yours to hear if there is a diference 
i send ya also an MP…
Peace&DIY
Manu.
Yasuhiro,
I probably will never build one (because I am very bad at soldering), but I would like to thank you for sharing the schematics 
Gwaaan !
Thanks for sharing…
But this schematic can’t actually be working…
There must be a mistake around the LFO (PNP astable)
It can’t oscillates wired as specified In that schematic.
Respect
Thanks,OK update soon
Diagram Is correct
Need somebody’s help to be complete shematics
Please report me after checking
Somebody can rewrite schematic from Diagram?
hmmm…for me the PNP part seems correct except the upper left ground wired to switch and diode that should not exist here…
Now Updating Schematic
temporary file is here
siren-machine.com/NJD/NJD%20TEMP.png
sorry very ugly Schematic, check some one please!
Diagram is Correct, It works If you make as Diagram
Thank you very much Yasuhiro!
I’m trying to build it from your diagram.
But I have one missunderstanding.
–>On page 5, the rotary switch for the Rate:
The A tip has to be linked with to 18.
Where is 18 on the PCB please?
yo mac, le 18 est relié a la masse…
merci!
J’attends plus que le facteur pour les transistors 2SA1015 que je n’avais pas et je croise les doigts pour que ça marche!
tien au jus des que tu as fini macgyver
Au pire si ca marche pas tu trouvera une solution haha
Bon courage
I have a mistake diagram
Rate to18 mistake to12 is Correctly
updated diagram please download again
Thanks
12/18 &6 are the 3 common points of the 3 poles of the rotary switch… on your wiring diagram shematic you just have to write « to ground » instead of « to 12 »…
Yes that’s right
Updated Ver1.2file somebody Check Please
I need your help to share diagram
Hola!
Quelqu’un a-t-il réalisé la siren avec les schémas de Yasuhiro?
Il y a beaucoup de différences entre la première et la deuxième version de son schéma, les transistors et les switchs ne sont pas câblés de la même manière, et il y a des incohérences entre le câblage du switch Mode (NJD05.pdf) et les deux versions de son schéma structurel.
1ere version:
2ème version:
J’ai envoyé un message à Yasuhiro sans réponse jusqu’à présent, si quelqu’un a plus d’infos merci d’avance
je suppose qu’il a reçu des mails de menace alors il brouille les pistes…
en tout cas pour un gars qui pretend construire des sirenes depuis je sais pas combien d’années y’a un truc bizarre dans sa demarche et ces plans effectivement…
j’ai pas encore construit sa version…je pourrais vraiment la debugger a ce moment là…
