    Amplifying OTA signal...

    Another wonderful tool is located here: http://www.tvfool.com/index.php?option=com...r&Itemid=29 Put in your address and it gives you a table and graph of the stations and how strong they are. Further, you can select the button for post Feb 2009 when some of the stations return their UHF...

    Amplifying OTA signal...

    In general, amplifiers should be used to eliminate the effect of the cable. Using them otherwise is liable to overload the input on your receiver and at any rate, they add a lot of noise. So the best place definitly is on the mast near the antenna. The most authoritative web site on HDTV...

    CEDIA Reviews??

    No reviews... It has been unusually quiet. I just arrived in Denver so if I see something interesting, I will post (although my speciality is mostly AV as opposed to control). Here is a decent site with most of the announcements: http://www.hometoys.com/show_news.php?show=cedia08 Amir

    Linear Actuators 101

    On boats, we use electric valves like this: http://www.westmarine.com/webapp/wcs/store...mp;classNum=691 Kind of pricey though but it does have a saftey shut off and sensor. There is a cheaper one ($50) here but no description: http://www.boatersworld.com/product/337410195.htm

    Special Brultech ECM-1220.H offer to cocoontech members.

    In the normal course of operation, that is true. But if the wires ever got snagged inside and managed to touch one of the breakers, then you do have 120v travelling that line. This is why they emphasize someone qualified running that wire to make sure this doesn't happen by accident. I would...

    Elk M1G output relays

    How handy are you with simple electronics? Because if you are, you can build a "one-shot timer" using parts from your local Radio Shack. Here is a quick link to what that looks like: http://home.cogeco.ca/~rpaisley4/LM555.html#2. By using the appropriate resistor/capacitor value, you can have...

    Hardwired Lighting System Using Cat5

    BTW, the company does have contact information: http://www.tpicorp.com/ Try sending them email or call them to see what they say. Tell them you want the schematic for the wiring/switch.

    Hardwired Lighting System Using Cat5

    I found the company web page for that unit: http://www.tpicorp.com/Catalog/INDUSTRIALF...ticFans/cat.pdf Alas, it is devoid of the schematic for the switch. Can you access the switch easily? If so, try to find the markings on that. I am pretty sure they would use an off-the-shelf switch we...

    Hardwired Lighting System Using Cat5

    That would certainly work. But if dual speed is important, then you can accomplish it still. Can you disconnect the switch (be sure to first turn the AC mains off!)? If so, try this. Use a multimeter and check connectivity between the switch wires. If my guess is right that in low mode, the...

    Hardwired Lighting System Using Cat5

    I doubt very much that different voltages are involved. That would make for a pretty expensive controller/switch. Instead, I think the motor has dual windings (hence the reason you have two power wires). On low, one is energized and one high, both are. If so, all you need is two relays to...
