Launch Controller Links

I’m still researching the details for building a rocket launch controller, the major part of that so far has been figuring out the best relay.

For the launch controller I’m looking at 12-24V and potentially high current before the igniter fires.  The minimum resistance for igniters seems to be around .5 ohm which at 12 volts would be 24 amps.  The first link below also discusses inrush current which is somewhat higher than the calculated current indicates.  Also want to be able to control this with an Arduino or other μC.

Here are a collection of links I came across in my search:

Possible Relay, seems like it may be overkill.
