Here is working fine. I tried it out in real but was not working :-( ***(updated)*** :-)
##Please if you'll try it in real and find the fine best values of caps and resistors to make it work please leave a comment or sent me the link of yours.##
-------------------------------------
3/apr/18 update:
Now is working in real. Check the values. The gate is a common 7400 quad nand. The value of the 100nF cap is not critical you can use any value from 10nF
