Either buy >the right stuff to do the job or accept my offer. BTW: My dial cord is >made in Taiwan, not China. You didn't say in your post you were sending it for free, just that you had it. I think the original was .5mm, but .4mm would probably work. However, I dont know what the shipping would be. If it's anywhere near what I saw on Ebay, I wont do it. $45 shipping for 12ft of string wound around a tiny piece of cardboard is ridiculous. Apparently shipping from Aus. is extremely high. I'd rather just buy a spool of fishing line and have it on hand. But since no one on this newsgroup is willing to give me a brand name and UPC code, then my whole question was a waste of my time. I looked at fishing line at Walmart. I never knew there were so many brands of the stuff, with prices ranging from $1.29 to over $15. All of them are sealed in plastic, so I cant determine the thickness, and all of them sold appeared to be single strand clear plastic, rated by weight, not diameter or material. So, the hell with any further comments from me. I have a few email addresses of people who are ham radio operators. Maybe they can provide some real help, since it's obvious I wont get it here. |

You were provided with a wide variety of solutions, including the correct stuff to do the job. Including my offer, of course. I looked at > So, the hell with any further comments from me.

If you can't recognise real help when you see it, you don't deserve it. If you still want the stuff, send my AUS$2.95 and your address and I'll post you a few Metres. -- Trevor Wilson www.rageaudio.com.au |

Apparently shipping from > Aus. is extremely high. Or perhaps you need to have your eyes examined or stop using an old round screen CRT as a monitor. Here's 32 feet of dial cord shipped around a "tiny piece of cardboard" from Australia for less than 6 bucks U.S. You can do a lot of radios with 32 feet including screwups. http://www.ebay.com/itm/DIAL-CORD-0-8-mm-synthetic-cord-10-metres-to-suit-radios-/222592615826?hash=item33d38dc592:g:AGkAAOSweW5U2Wln > So, the hell with any further comments from me.

You should probably take Trevor's offer as "free" seems to be as low as he's willing to go (unless he throws in a Super "Shammy" if you order now!!). |

Circuit values are easily calculated for the required delay, and the 555 can drive the triac directly or through an optocoupler. What's the normal ON time for the existing circuit? Do you use only the photocell input or in conjunction with the reed switch input? Dave M |

Oopsie!! Got the 555 output connected the wrong way to the opto driver.

The time is anywhere from 1 to five seconds depending on the operation required, which is easy with the 555. And yes, turning the TRIAC on/off rapidly with a reed switch is sometimes needed. Not sure if the 555 can be reliably triggered via a CDS cell using a strobe flash when there are varying light levels - day/night, and flood lamps - which is the current situation. Easy enough to test though I may just give up and go with some sort of Arduino replacement system where I can have several devices run by a few Arduinos (I have 60 of these boxes you see) and this would reduce or eliminate false positives that I get when there is a bright flash that lights up the entire area - right now everything fires off if someone takes a flash photo with a camera, but are not set off with a flash photo using a cell phone - LED flashes don't effect CDS cells much it seems.

The 4007 is rated for more voltage and current. Seems like there must be over 50 dioides that are rated in the range of 100 to 1000 volts and arund 1 amp. I don't know why they have to have so many to do a simple job. It reminds me of a company that makes fuses. They have about a dozen types and holders for each amp rating. The factory man said it was so they could advertise they had a fuse andholder for many applications. Just a way to get a company to stock about 5 times as many fuses for spares. |
