Hi, First I dont know the electronics stuff well but I can follow a shematics if this is not too complex.
I want to make a Combination lock for my car with 4 or 6 digits ,press in order to control a relay wire to an MSD 6al Ignition. I look at some shematic on internet one with a decade counter and another with a 4013 (dual flip flop) and I did some search on the forum but PIC are too complex for me. I like the 4013 its look easy :
**broken link removed**
But I dont really have an electronics store near me to buy the 4013 and I have a Box of old electronics board I did some search on part found in the box and I found a quad comparator DBL339 and 3 or 4 LM2902(that a op amp but still have to desolder them) and 3 lm324n(op amp too). I read somewhere you can use them like a flip flop and that exactly what the ic 4013 do.
I want to use the dbl339 if possible anybody can modify or create a shematics for me please? The circuit will be on 12volts with a 7812voltage regulator ,and If its possible to get a led turn on for a couple of second for telling you the code was right .
and Last question do anybody know what kind of current or voltage the white wire on the MSD 6al got? I got a couple of 12vdc 30a/40a relay but dont know if I really need that kind of relay.
Thanks in advance
