Does this schematic look good?

Horse shoe yep that's kinda what I was trying to say in the email.
Looks fine you could save even more space by squishing the resistors side by side where needed.
Put the power supply caps up above the input.
Turn the d2,d3 around. You could probably save a further 4 or 5 holes in pcb size.
It's just a matter of tweeking.
If your using SIP pins for the transistors that will save some space too. Not that I'm a miniature pcb freak but, it will save money and you have extra left over board for another build.
Have fine refining.

Okay, I tried to scrunch it together but I'm no good at this and very slow t'boot!
Anyway, I think this will work:


and the scheme for easy reference:

Good Job that you have learned to use DIYLC for perf builds! This new skill will pay major dividends! I think you will find that once you make a build to work on perf, re-drawing in a CAD program that can generate gerber files is easy. Then (if you want) getting a board made is simple and cheap.

An endorsement from smallbear. Cool.
He has a point about the cad.

Thanks Steve. I owe 99% of the credit to Kipper for this, I was spinning my wheels until he showed me how to do it. Thanks again everybody, I'll keep y'all posted!

I would suggest 2 small changes (this won't change your layout)

1- Swap the order of the 47R and the Schottky Diode (just swap these components on the layout) Why? The 47R forms the lowpass with the 2 caps.

2- Take the power for the LED at the 9V input (just connect row A columns B and C, remove the connection to Row J column D). Why? Less current through the 47R, thus less V drop. The LED has reverse polarity protection by design.
Some people drink from the fountain of knowledge, others just gargle.

Okay, got it Russ, will do, thanks! I was wondering earlier if that 47r/diode order made a difference. Also, I was going to put a 47k from my super brite LED to ground... is it all the same to have that resistor come from that +9v terminal and go to the LED? I think I could fit it on the board right there.
