I am breadboarding up a version of your 555 circuit, and was wondering
if you could provide any ball park figures for the unvalued components
(capacitors, Leaning pot, R1 and damping resistor), or ball park pulse
width range.
I know the damping resistor was mentioned in an earlier post, but
I'm currently working from web-mail, and cannot access my archives.
I'm substituting a TLO31 for the op-amp, and a 2N6660 for the FET,
just because that's what I have laying around.
Do the injectors require fluid flows for self cooling?
Sorry to be a burden.

On the damping resistor ask JCP. I have no idea what
he has in mind.

Here are the remaining values.
