Breadboard layout

I made this circuit and it is now working.

Nice one Justin. How did the breadboard layout come about? Is is part of special software and does it allow you to simulate the layout before building? Perhaps you could put the wailing siren and the servo tester on such a breadbard. That would be very much appreciated.

It's nothing but an image file that I made with Paint.NET; a free program that anyone can download. The components were made by the Admin of this site, I simply arranged them in the proper order. I'll take a look at the wailing siren and the servo tester for you. I wish it was able to simulate builds beforehand, but I do not have a program like that in my hands. I test out circuits on actually breadboards, hoping they will come out right.

The speed of the flashing LED can be sped up if you lower the value of the 680K resistor or the capacitor. Both can be changed if you want rapid flashing or you can increase the values for a slower flash.

I put this circuit onto a circuit board​

that looks amazing Justin!

Thanks! The process I used was taking a 1 sided copper plate and using a plant growing light I engraved my design onto the copper itself. Then washing off the copper I didn't want via chemicals. After that I had to wash it off in more chemicals to be sure that the it was done thoroughly. Once that was complete all I had to do was drill the holes, put the components in, and solder accordingly.

The closest video that I've got to what I did was this, he's missing one step that I did, and that was having to put it in an extra chemical. His process is also a tad bid different, but generally its the same thing.
