How on earth did I miss this project until now! I so want to make something similar and plan on using the Sparkfun Gap Ignitor

 

Great work Frankie. Awesome project.

We had a DIS from a friend.. its one from a toyota aygo.

The signal from the netduino went to a relay(controlled by the netduino) then through one of the missle switches through the cable to the little box in the first picture where the transistor was.

I used D0 on the netduino and switched the relay from the netduino. The missle switch was just another precaution because you had to physicle clear the line.

 

I've put a 18K ohm resistor on the base and 5v on the collector. In the little box is a small push button to manual make a spark for testing. the signal wire from the control unit was also protected by a diode so there wasnt going to be 5v on the line when you pressed the push button.

 

ive stabalized the power from the car battery with these from bitwizard: power stabalizers

 

next year we get the linux drivers compiled on the PI for the touch screen and the WIFI Accespoint.. 

 

ps. if you need the code, send me a PM.. im happy to share it

 

psps im gonna get me an ignitor from sparkfun..looks awsome, just have to find the correct mosfet for it... have to shop for new gear anyway now my netduino plus is stuck in a lexaan box lol

Steve,

 

I didn't think Canadians were allowed to play with things that went boom! Or high voltage.

Only on special occasions like Guy Fox night and New Years. Though we do have some lenience in that if we blow something up, we just have to apologize and all is good.  :)

While it's great that you learnt to DIY, you can save yourself a lot of messing about with one of these relay shields.

@Arbiter, using a relayshield for all other operations(mostly savety) but its not suitable(not fast enough) for making a spark. tried that in the beginning.
