Reply to "Semaphore and 555 Timer Circuit"

Thanks! I appreciate the kind words. I should have added above that Diptrace did most of the routing with a couple of minor adjustments, I only arranged the components. Diptrace isn't too good with the component placement, I started over on that part after Diptrace got finished. 

I made it larger for the mounting holes and to leave some room for naming things. I goofed up the mounting holes on a couple orders. I think I could shrink it a bit, but probably no where near as small as you get them. I also had problems with the terminals and another component or two not fitting too well on some of the previous PCBs, so I probably have some things spaced a bit too far apart, just for safety. 

Also for size, OSHPark is too expensive for all the PCBs I have had made for this project so far. As I recall they were $17 and up (some over $20) for all that I checked there. JLCPCB is only $2 for 5 PCBs up to 100mm x 100mm with 24 hour turn around, but they add $5.50 for standard shipping (2-3 weeks or so). Still not too bad for price. With JLC, DHL (2 or 3 day I think it was) is also an option. Drawback there is the price, instead of $5.50 I think it's around $16-$17 or so for that option.

As for any credit, that should all go to Stan and you for all my training. I could have never done any of this on my own without assistance from both of you.  I think it was the TIU tester project that really got me going. Ordering the PCBs and parts and things for that project prompted me to try and make something from scratch. Of course, that is with a lot of help you two.
