Re: is the gate open or closed
Lots of great stuff to think about here. I will try to answer most of the questions asked so far. I could bury twisted pair but would prefer not to. Its about 800 feet and I'm really trying to avoid actual work. I could easy power a transmitter with a gel cell and solar, and may go that route. The g...

Re: is the gate open or closed
Gerty, no, the gate is not powered. Maybe will be at some point but no access to ac lines.

is the gate open or closed
I believe I saw a thread similar to this earlier but failed in locating it. My driveway gate is about 800 feet from my house. Anyone think of a kit or simple rf circuit built or not, to tell me whether the gate is open or closed? The sensor will probably be a magnet or reed switch or something simil...

Re: power transformers
They came out of cabinet X-ray machines which were decommissioned. Hated to just send them off to a scrapper if someone could find a use for them.

power transformers
I have some 10A power transformers removed from equipment that is being de commissioned. They are multi-tap input, from 100 to 250 volts, with a 230 volt 9 amp output. They weigh about 32.5 pounds. I'm not trying trying to make a bunch of money, just trying to avoid recycling if someone has a use fo...

Re: SatNav precision, accuracy or resolution...
Ceasar and Dyarker, thanks for the additional info. I appreciate the info and will file it away in my brain to recall it incorrectly in a few more years. The precision Nav stuff is really world changing technology. In my early days in the Coast Guard would have never even dreamed about this kind of ...

Re: SatNav precision, accuracy or resolution...
Hi Miguel, I can partially answer your question, maybe someone with more technical knowledge can fill in the blanks. This info is anecdotal and may not be 100 percent accurate but I believe its pretty close. When GPS was initially conceived, it was intended for military use only. Primarily US Navy, ...

Re: electro magnet
Wayne, save yourself some trouble cleaning the magnets and put a plastic "tear away" sheet over the magnet befor you use it, then you can just peel away the plastic and keep your magnets from getting fouled with iron filings and such. Little bits of metal are almost impossible to remove on...

Re: Emulate a Keyboard with a Notebook PC?
cpbiomed, did you come up with a solution? I have a similar problem with the x-ray systems I work on, although they are cabinet systems, not medical. I assume you are talking medical?

USB to serial convertor with Windows Vista
Hi all, I use a USB to serial converter for programming a Uc based system. The problem I have is that when I plug into the USB, Windows assigns a com port, seemingly randomly each time I plug it in, which then forces me to guess which com port I'm working on. This creates all kinds of issues as my p...

Re: timed outlets anyone?
i have electronic delay switches on my bathroom fans, they fit in a standard wall box, and have about 5 different buttons you can push for on times from 5 minutes to 1 hour, or a constant on. Would be easy enough to put in a box and do what you want. I think they cost about 25 bucks at home depot. Tom
