Serge Posted June 30, 2004 Author Report Share Posted June 30, 2004 gronberg, not so much a relay but an intercooler, like the lm555 can be programmed for double shot pulses, instead of single shot. further up in the post I think there is a link for the lm555.Yep.LM555 is great, though I'd rather use a microcontroller. Much more control, not much more expensive ($2 for an Atmel ATiny vs. $0.50 for the LM555) and less external parts (voltage regulator, resistor and transistors).

gronberg Posted June 30, 2004 Report Share Posted June 30, 2004 Thanks,But I'm right where I would put it in between the M- and the NC, or it doesn't really matter?How would the microcontroller work? Does it store the current that comes from the M- and then gives it out in the number of impulses that you want.I was thingking of making the looking one long blink, like 4 sec, and the unlook 3 blinks.Liquid, or anyone else, where is a good online store to get these parts that is needed for this mod?

I would use one pin to trigger it's locking code that would send one output high twice in a second or so. The output would trigger a transistor that would make the lights blink.

gronberg Posted June 30, 2004 Report Share Posted June 30, 2004 so 2 relays, 2 NC relays, 2 microcontrollers, and a transistor.How large should the transistor be?Then I put the transistor after the one microcontroller for the M+. Link to comment Share on other sites More sharing options...

gronberg Posted June 30, 2004 Report Share Posted June 30, 2004 true, because if it is enough juice in the transistor it will be solid blink until it runs out. How big do you suggest it to be?Just looked at some microcontrollers and it looks like I need alot more then knowledge I have in this.Basic electric for engineers and that pushed me out of that field and into Industrial Eng.Liquid, if I asked really nice, could you put one together for me ( microcontroller to bink twice) so I just could put it with the DPST relay and the NC relay. Ofcause I would pay you for you knowledge and effort.Thanks Link to comment Share on other sites More sharing options...
Serge Posted June 30, 2004 Author Report Share Posted June 30, 2004 I was thinking of coming up with this for myself, so if I do I'll provide it here. Link to comment Share on other sites More sharing options...
JehovArob Posted July 1, 2004 Report Share Posted July 1, 2004 Well, I got my relays and diodes all soldered together. Am going to hook them into the car tomorrow and will see how it all works (cross your fingers).I think I'll stick with the good old single blink each time just 'cause I don't really feel like going back and redoing it all, but would love to add a horn honk for when locking the doors. Is doing this with that LM555 chip something that could easily go in along with this relay setup? Link to comment Share on other sites More sharing options...
JehovArob Posted July 1, 2004 Report Share Posted July 1, 2004 Well, it works great. I too had the same problem finding the correct yellow wire as there are a whole bunch, but got it right on my second try. Got blinking lights when doors are locked/unlocked and doesn't do it when the car is on with just 2 DPDTs and 2 diodes. Probably could've done it with 1 DPDT and 1 SPDT and the 2 diodes, but whatever.Now, about the horn honking? Link to comment Share on other sites More sharing options...
550 Posted July 1, 2004 Report Share Posted July 1, 2004 still wokring on timing with a few various options heh Link to comment Share on other sites More sharing options...
fhrcng Posted July 1, 2004 Report Share Posted July 1, 2004 When you get this thing done with all of the different options why don't you write a more concise and complete set of instructions? That would be a great and informative piece. Right now some of it is sketchy. Also, I like the horn idea. That would sound a whole lot better than the jail cell door "clunk" that our cars have now. Don't get me wrong I think this is a cool piece I just think it needs cleaned up to make it less confusing for the members who are not electrical gurus.Keep up the good ideas. ;) Link to comment Share on other sites More sharing options...

Rabbit Posted July 1, 2004 Report Share Posted July 1, 2004 well, it is a learning experience.Good point, 550. I'm sure that as this project is completed, there will be a more concise detailed report submitted. I am pleased to see so much interest in this endeavor. Cheers!

Guest UnsanePyro Posted July 2, 2004 Report Share Posted July 2, 2004 Space is to darn tight down there for all those wires, it's what has kept me from doing it so far, figure it will take decently longer then I expected to complete. Link to comment Share on other sites More sharing options...
550 Posted July 2, 2004 Report Share Posted July 2, 2004 I actually didnt even bother with the wires from that bundle. I grabbed the whole remote control unit out from under the dash. It took a helluva time, but it was well worth it, I got the m- wire on the first try, and I wouldn't have otherwise.If you want to try getting the box out, basically you have to contort your head under the dash, I did this by sitting backwards on the seat putting my legs up around the headrest and then lowering myself under the dash. I was then abel to see the box(remote unit). It is black and connected to a metal part of the car. It has a green connector going to it, with ALOT of wires. Also it is slightly to the right of the steering wheel. Good luck, if you need I can try to get some pictures with my phone, or borrow a digi cam from a friends.Oh BTW you don't have to get under the dash the same way I did, it was easy for me because I'm only 5'8".
