Nice pics.
I made my own cam last spring, I got a lot of nice pics from it. my setup was pretty simple owl pf date, RS Sensor, 5vdc reed relay, no timers or anything like that, all in a mititary ammo can. unfortunatly Mine got stolen about a month ago,
I just finished making a new one a few days ago though, The nice thing about them is you can Make 4 of em for the price One of the store bought ones.
Just be sure you keep it chained up tight and out of sight!
