| Michael Mud <michael.muderick@gmail.com>: Dec 22 08:53AM -0800 I use a few of these boxes on older tv's. They are the ones Radio Shack sold. I like to use them with timers, which I program more than a day ahead. The a/d boxes ARE NOT PLUGGED into the timers. What I'm finding is that they shut down on their own, after sitting idle for a number of hours. Are they dependent on a tv being on to stay on? Is there a sensing circuit, or are they just old and tired. TIA. |

The setting is intended to be nonvolatile, so you don't need to visit it often. |

I'm sure that's the problem. Didn't know it existed. Happy Holidays |

FWIW, as a general warning, many of these types of units have bad wiring and violated basics safety principals, such as proper grounding, improper fuse placement/rating or most likely no fuse at all. In this and various other electronic/electrical NGs, there are discussions about what people find. Do some googling about your device of interest and see if ppl have complained. You may have to do some re-engineering to make the thing safe. While the pricing of this stuff is really attractive, I will get this stuff from reputable mfg. |

About two weeks later, Ebay refunded the money, and the seller no longer had an account on Ebay. Like in these ads, there were hundreds sold, and decent feedback. Also, you have to be careful. Some sellers don't tell you that their soldering tools are 240VAC instead of 120 VAC. |

Some sellers don't tell you that their soldering tools are 240VAC instead of 120 VAC. I was mostly courious to see if I could get one for the $ 13 price. It does sound too good to be true. It would make a good spare unit for the one I already have. The 240 volt problem is something to keep in mind. Going through ebay and paypal I doubt I will loose any money, but $ 13 won't break me. I have gotten 2 refunds when I did not get the items from China. I never order anything from over seas if I really want it or want it in a week or two. I have probably bought 2 or 3 hundred items from over seas. Good results from all but 2 that was made good. Most were in the $ 10 range. Amazing what kind of trinkets you can get from there for almost nothing. Most work like I expect them to. I look on Youtube for some of the items and ofen see where someone has modified them to work much better for a few dollars of parts. I just modified a $ 15 audio generator from the Youtube instructions for another $ 5 that makes it work much better. I have enough parts left over from that to do several more. |
