MK126 simulated car alarm

Hi,
is it possible to change the flash rate from 4 flashes to just one flash -
for instance by changing the value of C2?

if so, which value for C2 do I need?

what I would like to achieve is one flash; off (no flash) for anything between 1 and 4 seconds.

thank you

Tolerance of a cap can be up to 40%, so you will need to experiment for best results.

I am not very good with electronic circuits but can assemble a kit with instructions.
The MK126 produces 4 quick flashes every 3 or 4 seconds.

If possible, I would like to change this to 1 flash (instead of 4)

What I would need to know is:
what do I need to change ?

  • change C2 from 1uF to 2uF ? (or other value?)
  • and/or change any of the resistors? (to what value?)

I would be grateful for any help
perhaps someone has done this before?

Thanks
GM

You could try reducing the value of R13.
Sorry, no values, please experiment.
There is no risk in harming the circuit.

Bonjour
Suis possesseur de ce kit qui fonctionne bien et suis interessé par ce post.
J’ai pas bien compris faut-il changer le C2 et la resistance R13 ou uniquement la résistance ?
D’avance merci pour votre réponse…

Bonjour,
Doit-on uniquement remplacer la résistance R13 ??
Merci de votre réponse…

You could start experimenting with R13 only.
