Dub Siren, the Build - 555 Timer Project
Вставка
- Опубліковано 10 вер 2024
- This is my 2nd go at building a dub siren. This version users a custom PCB that I designed based on the 555 timer and 741 op amp. I've also included a reverb and echo and audio amp modules, all powered from a mobile battery.
The case is an old intercom In found in the dump.
This is the longer build video of this build. I've also published a short, demo version of the build which can be found in the link below.
I've also published a step by step build guide on my Instructables page

The schematic, board and gerber files for the dub siren can be found in the link below.

Man this is the COOLEST. I can't wait to build one! My friend Aisha does a modulation pedal in that same enclosure, and I sent her one that I found in a thrift store. Great build! I subbed brother, looking forward to more tinkering.
Bless!
Fantastic build. The echo really takes it to another level
Cheers!. Yeah the echo gives it a great sound. Makes it a lot more fun to play as well.
Great build video, I becoming more and more envious. A great idea to recycle phone batteries as a power source also, Im still going through a ton of 9v batteries! Cheers!
Cheers! I was also burning through 9v batteries in my builds. Mobile phone batteries have worked a treat and I've been getting them for free from those phone recycle bins.
Absolutely fantastic build and video, thanks for sharing. Having studied electronics in college and built basic sound modules (a looooong time ago) this project really interests me - especially because I love reggae and always wanted a dub siren.
Question if you don't mind me asking, to test the dub siren module by itself do all of the components for 90° connectors need to be connected? I am waiting for my wires to arrive so thought I might be able to connect the speaker to the dub siren output that goes to the echo/reverb module and get audio, but I don't.
This is great. How could I add a power source (wall plug) and rca out to connect with my dj mixer?
You can easily add mains power by swapping out the battery and connecting a 9v DC adapter to positive and ground.
You can connect an RCA as well - you just need to connect it to where the jack out goes instead of adding the audio socket for a 3.5mm jack. Note though that it won't be in stereo
Sorry, this is my first time building something like this. Would 12v work as well for power supply? And am I right that I don’t need the little board connected to the battery if I use an external power supply? Thanks 🙏
@@lonesoulsurfer When you say "an rca" will there only be sound from one channel? So it wont be mono either?
@@lonesoulsurfer Sorry, I have more questions. If I add the RCA to the outputs from the small amp, will the signal be too "hot" for my DJ mixer? If I take the output from the Dub Siren PCB... I won't get the delay effect right? Is there a way to wire the thing so I get sound in my RCA both left and right channel?
@@madsappeal You will get sound out of both channels but will need to connect left and right together on the PCB. it just won't be in stereo - only mono. You need to take the output from the echo/reverb module to be able to get that effect.
Would this be possible on a breadboard (without soldering), because I can't access my Uni facilities in lockdown.
You can easily make this on a breadboard. I did it when It when I first designed the schematic to test it
I build one using the chips. 4093 and 4046 but the reverb don’t seem seems to have all that effects
Try disconnecting the echo module from power and reconnecting it again. Did you also remove the R27 resistor? You need to do this for the echo to work
Thanks for your replie I did that it’s working maybe I was just looking for more , thanks
Do you think the audio quality would suffer if you used an Arduino/Atmel for this type of project? thanks
I don’t think you’d have any real noticeable difference in sound. However, as the one I built is analogue it prob does have some nuances that give it the sound it does
It sounds great! thanks so much for helping me understand how it works with the detailed schematics and videos. (I'm still learning)
Walter Blackledge good luck with it. It’s a pretty straight forward build if you have the PCB printed up
thanks. I want to try putting it on a breadboard and giving it a 1/4 jack to run into a mixer, which means not having the speaker attached or battery / charger either. I'm a software guy so hardware is something new for me. thanks!
thanks fort his, ive ordered parts and am starting this project. Your link sends me to ebay to order 50k 8 pin pots, do i really need 8 pin pots or a 3 pin pots fine?
all the pots should only be 3 pin.
Good luck with the build!
@@lonesoulsurfer thanks man, finally - how important is it to use op amp sockets, i could not see them in your component list?
@@dramaone891 You don't really need them but I like to add them so if any of the IC's don't work I can swap them out easily.
For some reason I can't reply to your last comment re. only getting a faint sound out of the dub siren. I think you might have the momentary/always on switch wired wrong. The faint sound you are hearing usually happens when the momentary button has been turned on. You can just hear the siren still on and then when you hit the momentary switch it plays at full volume.
Actually, scrap that. I put another together yesterday and found that I was having the same issue. It seems that there is an issue with the audio socket soldered onto the board. Use the header pins instead and it'll work fine.
It was a bit of a mess (one of the first boards I designed!) so I have cleaned it up and added to my Google Drive. Link in the description
Thanks for the project. Why first siren didn't work with one 9V battery and this one does?
Because I was a noob back then and didn't know what I was really doing.
@@lonesoulsurfer Haha. But whta exactly was a cause?
@@LeniFromMemento For some reason when the circuit I built and the modules were all connected to the same power I was getting some weird feedback effect. I assumed it was due to the circuits sharing a common ground so I used a different power source for each and it did the trick. For this build I didn't have the same issue
Does this work off batteries ?
Also how much would you sell one for ?
Yeah it works off a 9v battery.
I’m not selling them at the moment but will possibly in the future
lonesoulsurfer how much would one cost if you sold this type ?
Are you selling these yet ??
Very nice where can I get your pcb ?
There's a link in the description to the gerber file, schematic etc
Belive you linked to wrong "pew" files. Thanks for this
Mmm... checked them and they look good to me.
@@lonesoulsurfer I insist in thankig you for this but I get linked to a folder named "Ray gun sound effects", I mean the link in the video description to the drive folder. Anyway the link in the instructables tut is fine, I believe
