I built two Cameras last fall and had a lot of fun with them.  I didn't put timers on them.  Well with Radio Shack having the PIRs so cheap I bought 3 more.

Is it best to build or buy your own timers now?  (for RS pir)

Thanks for any advice

I am in total agreement with AEH. I fooled around w/ a BUNCH of 555/556 combinations and junk, mainly to get my hand back into some electronics, and Brians chips are great. He will give you the delays YOU want, and they work like a charm. He also doesn't seem to get to irritated when you ask really dumb questions. Thats my 2 cents.

Hi CG,
Definately build a timer with one of Brians ICs.  You'll want to take all those 555/6s, capacitors, and resistors out back and shoot the lot of 'em after using Brians parts!
Wish he came up with this stuff several years back - I don't want to think about how much time I wasted on all my various complicated timer circuits :-(

Hi CG,
From Brian!  He's posted much of the info on functions to the forum and his web-site.  Search his "user name" (Brian) and you'll find his e-mail & web site address.

Here is a link to brians manual for hooking up his timer chip.

Brians Manual

He sells just the chip $7.25,  The etched board $10, or the completed timer board for $36.   He also has a complete board with a builtin PIR for $70.  The prices are close but He will have to comfirm they are still correct.  I just use his chip.  the new board may have day/night as an option.  He just figured it out so I don't know if he is selling it yet.

You will love the versatility of his control chip however you do it.  Here is his email link.

I have a parts list I can send you if you want to tackle it yourself.  I would recommend the etched board though.  The time you save wil be well worth it.

Good luck
