Hi,

if you could stay to english, the thread creator might be able to help us :wink:

I also tried to build this siren without success… it makes some noise - but not what I’ve expected >.<’’
A few month ago, I wrote to the thread creator on twitter and he said he would have a look… no replay so far…
Would be so cool if the schematic would just work… I think he might be confused by the strange Transistors in this circuit… so was I… never expected that the base isn’t in the middle ::quest:
