I wondered why drills and such still don't use a safety ground. I assumed it is still handled by double insulation. Thanks for a great explanation. I'll have to try and understand more of it. I only really got the neutral/ground potential, ground loop and GFI parts.
I'm not familiar with this and did not see the reasoning and/or assumptions. I wanted to comment that I don't see how "capacitive" is needed as a specific quality here.
Solar Heater for My Shop
This is great. Just want to add this:I'd suggest using propylene glycol. One way to get this is from AMSOIL (American Synthetic Oil (?) ) from independent dealers for automobiles. I believe this will be better against corrosion and I believe a similar chemical is used in building hot water heating systems. I would estimate a 50% solution will give a -25 degree F freezing point and will have a 15% reduction in heat transfer. (~$40/gal.)Also, for reference, the sun, on a clear day and maximum impingement, estimate 430 Btu/s.f./hr. solar gain. (Keep in mind a typical house furnace is 48,000 Btu/hr output (80% eff., 60 MBH input (60,000 btu/hr.) (1400 s.f. house, above average insulation, 80 degree design delta T)). Natural gas is doing THAT much for you!Don't expect any usable capacity from hot water storage from 20 gallons. (lol) You might need a bladder type expansion tank too (Watts domestic hot water (2 gal (?) - Home Depot, set for 20 psi (?)).Great project. I'd be interested in your results and comments. (I bet I know what they'll be like (lol)) -Ohio
Search "ls1tech aux input". Go to the first page of the thread. I am going to assume you're up to speed with any of this since you're on Instructables. This is tapping into a line-level (?) audio signal. If you have a factory satellite receiver, you should also be able to similarly tap/break into its audio wires; right outside the radio even.Now that you can follow the tapping, I'll suggest a solution to your question specifically. You can get a 12V AUDIO Bluetooth board by Sure on a place named Parts Express. Get your switched voltage, ground and do the tap/break with a double pole-double throw switch instead. You should now have what you're looking for.I have been checking into this for a similar reason (integrated information center display) for someone else. I have not done it yet, but am very sure this will work. If not, there would only be a small manipulation to make it work. These are this decade's most useful hack, IMO, LOL. Good luck.
How many lemons would this take? Just kidding. This is a good reminder of the acceptable voltage range!
Going to have to save this one!
I don't know how you don't consider this mutilating. The coins are now destroyed, unusable and the physical medium is now out of check with accounting. It's illegal.
It is illegal to destroy currency. Doesn't that just seem like it's something you shouldn't do?
Nice. That must be an interior wall, no insulation. As a note for others: Watch for utilities before cutting into the wall. i.e. electric, telephone, drains, vents or ductwork. The especially tricky ones are the ones that serve another floor and are passing through the working level. Corners also have high chances of smaller stud spacing. -not to be a party pooper, but this is the reality check before creating a bunch of repair work.

There's no need to excited. Yes, copying and pasting is how information is relayed. My point is that the significance of forging is obtaining grain structure for strength which can be done in cold forging also. Reheating hardened steel in a "forge" doesn't make sense then. Does it to you? It's heated in an oven even though everybody calls it a forge. No, English isn't a second language, and this contention comes from the processes learned in a Bachelor's of Science in Mechanical Engineering and metallurgy. Seriously, you don't need to try and berate. Educate your too.
"Hot forging and cold forging are two different metal forming processes that deliver similar results. Forging is the process of deforming metal into a predetermined shape using certain tools and equipment—deformation is accomplished using hot,cold, or even warm forging processes."Oven: A chamber or compartment, as in a stove, for baking, roasting,heating, drying, etc.Furnace: a structure or apparatus in which heat may be generated,as for heating houses, smelting ores, or producing steam.
Thanks for replying. FWIW, I think people are beginning to use words wrongly, and it spreads easily. BTW, there is hot and cold forging. Things are heated up in a furnace for hot forging.
I thought forging was the hammering and shaping of metal. I don't know how the furnace or oven has taken on the name as "forge" so much. BTW people, there is cold and hot forging.Nice looking oven BTW !

DIY Yellow Jacket Bottle Trap
I would suggest hot gluing it down to a brick (half is actually more applicable and desirable; score and hit with hammer on line). It will not blow over as easily and can tolerate water.
How to make a Mini Forge
Would this be better called a mini forging "oven" or "furnace"?
If you were to encase it with metal, would you want to add some ceramic fiber blanket to save gas or have the ability to get higher temperatures? This is a nifty little oven.
Is the taper intentional? Would this want to be pitched to direct the heat back away from the working end or induce air flow in? Thx.
I would guess this is used as a surfactant. That is typically used to lessen the water's surface tension. It is used often with liquid pesticides so it can spread over leaves better. Further, from a certain manufacture's "rescue" explanation, it will coat the wings and make it harder fif them to fly. I do not believe there is any appreciable density difference yielding different buoyancy.
Yes, it's usually written as x 5 or (5).
That is hilarious. Although made into a reality, I would have only thought this to be in the humor of the Flintstones.
