" Well, let's get started with Steve Bradley, our electrician, and Steve, I understand you've got a snaking project underway here?"

" Yeah Bob. We're snaking in a new thermostat wire for the air-conditioning unit that's been added. This is the original thermostat cable for the heating unit, but there's not enough conductors in the wire we need to conduct."

" Yeah, originally, the homeowner only was gonna have heating obviously, and then he decided to switch and add air-conditioning. So this cable is not good enough huh?"

" That's correct. My assistant, Chris, is in the basement. He's got a 20-foot snake that looks similar to this. It has a hook line like this he's sent up through a hole in the floor underneath this wall, and I'm gonna try and catch the snake with this end of this catch snake."

" Okay."

" And if Chris shakes the wire. Chris can you shake the wire please? Now I can hear its come right by this parts. I'm just gonna insert the hook here, and----"

" And try to catch it. So that the other wire is coming up in between the stud behind the wallboard."

" That's correct. This screw will bend in. Okay Chris, I think I got it. Can you feed it up a little bit?"

" There you go."

" Beautiful."

" Great. So that's his end of the snake, and now you just tie the new wire to it."

" We strip the end of the wires, slipping through this little loop."

" Through the loop."

" Fold it, give it a twist around, and then we wanna tape it up to make sure the wire doesn't pull off inside the wall."

" And that's probably the most important tip because you don't wanna have to keep, you know, pushing that snake through it to lose it."

" We got lucky this time, I think."

" Yeah. So I understand you're connecting a wind speed indicator up for the homeowner. Could we take a look at that?"

" Sure. Go ahead Chris, pull some down."

" Let's go in the kitchen."

" Beautiful."

" Yeah, well I understand Paul, the homeowner is an avid board sailor, and he wanted a gadget that would let him know when the wind picked up, but that looks pretty complicated Steve?"

" This monitor measures the temperature through a temperature and humidity sensor, so it's mounted on the peak of the house."

" Okay."

" Above that, extended on an 8-foot rod is the wind speed indicator."

" And that just the traditional little 3-cup up there, right?"

" That's right. It also has an aerodynamic fin that measures the direction of the wind."

" Like a wind vane on a mat."

" They can calculate the wind chill. This monitor calculates the wind chill automatically and would show you the wind chill. It measures the rain."

" More of."

" The rain is measured in this flat canister. The rain comes in to the canister. It's mounted on a flat level surface outside. "

" Uh huh."

" When the rain comes into the bucket, it activates this pendulum back and forth."

" Oh yeah. So each time it fills one of these little half cups, the weight of the rain water tips it over and it makes a contact there, and that's how it measures the amount of rainfall."

" That's correct."

" Neat! I like that. What else does it do?"

" Barometric pressure---- "

" Barometric pressure. "

" humidity,----"

" Yeah."

" and the dew point."

" Amazing. It probably cost an arm and a leg. I'll have to ask him. Are you gonna get it finished today? Next week, we could play with it, right?"

" It will be by finished by next week."

" Good. Thanks a lot Steve."
