edit- again, sorry but this is trader007! Somehow I am logged in as trader007 yet it posts as wirednuts. I must have two accounts... very weird.LOL! Yeah that would be hilarious to see. I love looking at hackjob installs.
I have been an electrician for over 10 years, with extensive training in safety. I don't do anything questionable when it comes to electrical work. I always over-do it a little. Also why I am getting into LED accent lighting, as it's inherently safe as long as you use the proper power supplies and install techniques.
The only electronics outside besides the diodes themselves would be the photo sensor and the PIR sensors.
I am going to try these sensors from china. I would rather have something from honeywell or whatnot, but the price can't be ignored with these- http://www.ebay.com/itm/221236158512
and the PIR sensors here- http://www.ebay.com/itm/350792365698
I was looking on digikey and noticed I could buy the actual photo and PIR sensors themselves, but I would need to add the circuitry to go with and that's just more time consuming. These come with what they need to work, in a nice small package. The PIR sensor has a 3min timer built in too, and I figured I will probably be able to add some capacitance to extend that to about 10min.
