Default OBD 1 & 1.5 laptop cable....

I'm going through this thread...

http://www.bonnevilleclub.com/forum/...light=scantool

And now I need to do this...



I need some help reading the diagram since i'm no good with them. I'm assuming the R'* are resistors, the Q'* are the transistors and the D is a ?

If someone could draw a picture, or give me a quick lesson on this, with what I need to solder together that would be appreciated....

Trying to get this working before the meet!

D is a diode. And you need to know what type of transistor they used.

two ECG289A transistors (any generic transistors will do -- 2N2222, 2N3904, etc),

I know radio shack can order 2N2222'*, To find out which pin is really which search the number or name or whtever you want to call it up on google.

yeah I noticed that.. okay.. damn I wanted to pirate software!! oh well. lol, i'll just have to wait till the next version of something comes out.

I think this is the one reason I am going to fix meh old notebook.. this is going to be so sweet! You can't enter in data though? like on an OBD II system? i'd love to be able to change some of the values.. especially change some of the values for free .

I just ordered a box of 500 transistors 1/2 watt [i think] and a box of 100 transistors [1/4 watt i think], all for only a few bucks.. so if someone doesn't feel confident enough or whatever reason, i'll make them. I'll do it for $20USD, including shipping. I added a little for myself, because I could use the money.. lol. I will test the units, if I can figure out a cheap case for the stuff, i'll include that for free, and it will have status LED'* [i'm not sure which one'* will work, but i'll include all that will.. [no more than 4]. If I can't come up with a case. It will have some half *** connectors [have no clue where to find "correct ones" but these work, so who really cares?] And default I will make the whole "dongle" 10ft in lengh. You can custom order it to your own length [ $0.50 per extra foot, you still pay the same price for less]. If I get a group order of 20 people by 8/20/04 [expected date to recieve stuff from radio shack], then i'll knock the price down to $15. I doubt that many people will order it.. but that'* ok. Once I get all the stuff here, and I have a couple made, i'll show you what you all get and stuff, along with a few being made, i'll post this up in the "for sale" section here on BC.
