Re: The right relay

Maybe I missed it , but I didn't see the current rating. Since it's line voltage it should be ok.
With a line voltage thermostat you'll need suitable wire, did you run romex or low voltage thermostat wire? It is the easiest way to go..

Re: The right relay

Except for the 9v (you stated 12 to 16v) they all look ok. Never tried a solid state relay on a motor before, I've used them on resistave loads mostly with a lot of success...

Re: Spy camera-wireless signal boosting.

Most wireless video is designed for line of sight.
In other words, you should be able to see the receiver from the transmitter. Could you possibly mount your receiver where it would "see" the transmitter . Then you could run coax back to the monitor/vcr...

Re: What's everyone working on?

These targets are something they already had, and yeah, I tried to tell them about binoculars and spotting scopes. They wanted something that all the spectators could see.They also like to brag about the high tech stuff they have.Now they're talking about motorizing the pepper poppers (targets that ...

Re: What's everyone working on?

A couple of friends from one of the local shooting ranges wanted me to "invent something to let us know if we hit the target at 300 yds".. They had cut out a 2 foot square piece of 3/4 steel plate, had it hanging off chains. My job was to build some sort of circuit utilizing an impact sens...

My job is in facility maintenance as a electronics tech, mostly I install network hubs ,fiber optic,repair boards for the...

Re: X-10 noise

A friend wants to control a small pump in a water fountain and I was thinking of using x-10 for it.
It's a 1/5 hp 120v motor do you think I'll encounter any of the above problems?
Or would it be better to have the x-10 control a relay?

Re: Wildboar

The one that I tried was single speed, vibrated like an electric toothbrush (future project?).
It was certianly faster than the manual pick gun.You realy couldn't control the operating frequency but by slightly twisting it, the needle would bind just enough to slow it down..

Re: LED Strobe

If you calculate your dropping resistor for about 16ma you should be ok. The dropping resistor will not "eat up" any current since the current remains the same across the components in a series circuit..You might go a little higher on the current if it's pulsed fast enough and the on time ...

Re: Wildboar

You can see one at southord.com. They have been around for a while. They vibrate at a high speed (ultrasonic?) and cause the pins in the lock to bounce across the shear line. When this happens you can turn the plug with a tension wrench. Basicly a much faster version of the pick gun (as seen on TV)....
