Hi guys,
I am an first year undergraduate, working on a liquid bi propellant engine at the Unis amateur rocketry team, and I have been asked to design a circuit to create a spark igniter system, for an ASI. However, I don't know much about circuits! Aerodynamics and thermodynamics are my forte.

I would really appreciate it if somebody could help me get started with this project, because it's honestly stressing ne out.

Thank you guys

Welcome to AAC!
Have you seen this?
Thank you so much for your reply.
Yes I have, however, I am unsure of what certain things mean. I am sorry if I seem like a complete beginner.
I have thought about how I might power the spark plug, with the little circuitry knowledge I have.

Can you use an off-the-shelf igniter, e.g. as used for gas ovens and hobs? There are versions powered by a single 1.5V alkaline cell.
