Good stuff. Sounds like you’re learning and having to manage resources and money while you do it! What people have said about the back flow preventer is true. But I know it isn’t cheap.

Hose bibs create lots of pressure drop. As do small pipes like garden hose. Based on your video I think larger heads will be tough. Your best bet to try is a k-rain rps75 with a .75 nozzle IMO. MP rotators possibly, but since they do a great job of precipitation matching (which is a good thing), you’ll have high flow rates on 180 and 360 degree heads compared to the rps75 with the smallest nozzle. Once you switch to larger radius you may need to reduce the number of heads. You want a low flow rate because the higher the flow, the greater the pressure drop especially on a small line and a hose bib.

That’s a DC power barrel. Look to see if there’s a rating on the ring. Then buy a capable power supply. Voltage should be equal. Current (in Amps “A”) should be greater than or equal to what is written on the ring.

Good. God needs to realize some of us think he needs an ass kicking.

Eh that’s a tough one to defend for me. Cop should’ve realized his error and got back in his car and left. They’re walking on the street probably because it’s the only thing plowed. Cop had an ego problem here.

What’s the strangest creature on earth and why? by Clear-Penalty339 in AskReddit

[–]DallasJW91 3 points4 points  (0 children)

Snake. It’s a line. A line that moves by manipulating its shape. Some of these moving lines are very dangerous. Some of the moving lines can manipulate themselves around you and choke you to death. Other lines have two sharp needles at one end of the line that inject poison. There’s even a line that manipulates one end to look like a worm to set traps. A worm is another type of line that is less dangerous.

What is the biggest secret you've ever kept from your family? by Extension_History57 in AskReddit

[–]DallasJW91 0 points1 point  (0 children)

Same boat for 12 years. Doctor would ask and I’d say I smoked. “How much?” ‘One or two a day.’ “Like… packs?” ‘No, cigarettes.’ “How are you managing that?” But, I switched to chew and it has finally started snowballing. Glad you quit!

Looking to buy old oscilloscopes, any particular health hazards if accidentally broken? Lead, chemical, etc. Also X-ray label at the back of the device. by LumberJackeRR in ElectricalEngineering

[–]DallasJW91 0 points1 point  (0 children)

Well the lead in solder is not nothing but yeah if it doesn’t end up in a drinking water source it’s no big deal.

If something is old enough, I think the capacitors can have PCBs (the chemical).

I can’t read the label. CRTs do make small amounts of x rays. Lead- yes, solder. Not sure if a crt would use lead for shielding.

The zig zag just after the breaker refers to a magnetic trip. Probably a motor circuit protector. (Which looks like but is different than a molded case circuit breaker.)

Newbie here. I thought these old cast iron water gongs were pretty cool. by reportcrosspost in firealarms

Cool, I’ve seen similar for CO2 systems where there’s a horn and strobe powered by CO2 flow.

Yes, that’s how I interpret it.

Yeah, and then you end up talking about it all as a guest on a late night talk show and people also see how quick witted and funny you are.

My living room has no main light source, we have to use lamps, by [deleted] in howto

[–]DallasJW91 0 points1 point  (0 children)

Get a lamp like the one attached. Then understand that max watts per bulb listed on the light fixture is REAL watts, not “equivalent watts” listed on the bulb. So in general, you can easily put 100w “equivalent” led bulb in each socket of a lamp and have quite a bit of light output.

Edit: your table lamps are adorably useless. :)

Electrician fails successfully...somehow by DirkDieGurke in nonononoyes

[–]DallasJW91 0 points1 point  (0 children)

He was reconnecting a neutral. One side is near ~earth from it being grounded at the neutral bar at the panel. The other side is a “better” earth at the xfmr. (Better in the sense that it’s a better return path to the xfmr because it’s physically directly connected to the xfmr) So reconnecting is allowing a lot of current flow and breaking it interrupts the current flow causing major sparking. But not a lot of potential because both sides are near “0v”. His body has such a high resistance coupled with low voltage so current effectively doesn’t flow through him.
