Hi,
I'm trying to build my own dub siren.
Im workin with 2 ne555 timers and 12v after the schematics of the DIY tutorial from www.rdh-hifi.fr/docs/Tuto_Siren_RDG.PDF
Now, as you will see in the attached pictures, i have assembled everything but it doesn't work. I need help troubleshooting this ting.. first my 220uf capacitor exploded then i noticed it was the wrong way around.. but now thats fixed, i am not sure how to test it. I have 3 lights.. but none of them work and switching some knobs doesn't change anything. Ive got my multimeter and can test for anything but not sure how to.
Any help would be much appreciated.
Btw i'm not a complete beginner, i have build a mic and some arduino projects but i am completely stuck here...
Any help would be appreciated.
Thanks & greetings,
Vale
