Greetings!
I am working on a project to control, via logic circuits, the ignition of model rocket igniters. My goal is to isolate the logic circuits from the higher voltage/amperage ignition circuit, and to do it with solid state components.
In order to work with a range of different igniters that have different voltage requirements, I would like the output stage to be designed with that flexibility in mind.
I have a circuit diagram of an output stage idea. My first question is if it looks workable as shown, or if I am way off base. The other questions involve what methodology or formulas I might use in the selection of the power transistor, and the calculation of R1, R2 and R4 (if the circuit idea looks sound).
Thanks in advance for any thoughts!
Sincerely,
Reynolds Kosloskey
