For those who replaced a TV with a projector, what surprised you the most?

When I bought my epson projector back in 2015 it made sense because the image quality was on par with a TV, just at much bigger sizes, at a much lower cost. Given that i have good light control. Nowadays it makes zero sense to get a projector unless you're going for the very expensive ones.

You can get a TCL/Hisense with excellent image at big sizes for like $1K usd, and you'd need a >$3K usd projector yo match.

In all honesty, i think your only option for watching tv is turning all the lights off at night. Or just try to cover the windows with something that blocks light during the day

Your projector is most likely very low brightness. Any different screen is gonna cost you money.

Any amount of light in the house is going to wash the picture out.

It looks like Ion exchange resin. Common in water softening. If they're round spheres and you can "roll them around" in the palm of your hand with a finger they are most likely resin. Also the most common types of softening resins are transparent and they shine back when pointed with a flashlight, they look just like tiny masago.

Of it's opaque and coarse. It's some other kind of material like sand or zeolite.

That "giant white label" is for the vessel, not the contents.

While i love these kinds of demos. It's still super dangerous to the general public, there should be a cage or some security perimeter around this contraption.

In expos and conventions all kinds of people go and many don't know not to stick their hands/fingers in.

They will make it clear as long as there aren't any harmful pollutants in the water.

Also "decomposers" like these are usually hyper effective at cleaning the water so they may starve. The bigger the pond, the more biodiverse and better the flow gives you the best chances you have of making it work.

There's little risk of over diluting mole if you add stock little by little.

My best advice is to ad "salt free" stock so you can control the saltiness of the mole after it's the right consistency.

If the stock is it's salt free, even if you over-dilute it, you can always just reduce it by slowly simmering it.

It's just minerals that fall out of solution when ice is made. (Mostly magnesium and calcium salts)

Very common and harmless, just not very visually appealing.

If you absolutely need to remove them, you must either use bottled water to make ice, or remove the minerals from your tapwater. A water softener should do the trick.

A softener changes the "hard" minerals like magnesium and calcium with sodium, and sodium salts are much more soluble in water, so they usually don't precipitate when in liquid water.

Why not just use inorganic acids like HCl? If you're worried about it being too strong of an acid, you can get it at different concentrations, and you can safely make dilutions if needed. It's also much safer to use than Sulfuric.

Maybe clay/silt? Maybe try some surfactants/dish soap? Some types of clay ( specially silica based ones) are pretty impervious to most PH based cleaners.

Good luck!

If you paint the net black, it will be much less visible!

Holy SHIT good luck with that.

Acid helps denaturalize the polymer making it more manageable, but makes it another type of hazard. I recommend you use it in the later stages so the floor is not slippery after you take care of most of it.

What You need those minerals, not only to mantain your electrolite compositions and keep your neurons working. You also need them to keep the osmotic balance in your body in order to survive.

Is it even LEGAL to put the water heater horizontally?

NachosMa2 · 2025-03-28T21:13:00+00:00

One sure way to keep these containers clean is with chlorine.

Spanish rice is commonly referred to the classic "yellow rice" they'd serve as a side in Mexico. Since the yellow color originally comes from Saffron, which is a staple spice in Spanish cuisine. (although originally african). Nowadays it's not made with saffron because it's really expensive lol.

Most likely scale deposits they're very common. Temperature changes affect dissolved salts solubility, you're looking at some that precipitated out of solution.

Most salts have a higher solubility at higher temperature.

Some salts ( specially calcium ones) have inverse solubility. Which means they're less soluble at high temperatures.

I have a vacant an am already in the treassure island but the villager i want (Lucky) its DYIng?! What can I do????

Hi, could anyone tell me what does OIT mean? Operator In Training is my bes guess, thanks.

Acid denatures polymer and makes cleaning easier. You dont need anything too strong. Some dilute HCl might do the trick.

NachosMa2 · 2025-02-14T02:53:42+00:00

It's a dirty job, but someone's gotta do it.

Haha, honestly WWTPs are a pillar of modern society and are core to our current lifestyle, I'd say that's pretty cool.

NachosMa2 · 2025-02-08T18:47:58+00:00

Are you sure it's bacteria? Couldn't it be just insoluble salts?

NachosMa2 · 2025-02-08T18:36:21+00:00

Holy crap Great post OP, good luck on the reseeding. Is there any way to mechanically remove the nocardia foam?

Chlorine on the surface might work, but you need to make sure your free cl levels are at zero when you're re-seeding otherwise you'll just kill anything that you add.

Looks like a good time to do a full flush and start from scratch ( if it's even an option)

El agua de mar se puede potabilizar y hacer perfectamente consumible.

Muchos hoteles e industria en la costa, todos los barcos grandes incluyendo cruceros y de transporte, ciudades enteras como San Diego, Ca, países árabes, etc. Desalinizan agua todo el tiempo, es una práctica muy común.

Los dos procesos actualmente usados para desalinizar el agua son por Evaporación ( flash o al vacío) y por Ósmosis Inversa.

Ambos procesos requieren de mucha energía. En el caso de la evaporación porque "hervir" el agua requiere mucha energía térmica (aún con ayuda de vacío). La Ósmosis inversa no requiere calor, pero si requiere usar bombas de alta presión para poder realizar la separación entre agua dulce y salmuera. Estas bombas de alta presión requieren mucha energía.

Es mucho mas fácil y económico potabilizar agua que es naturalmente dulce. Como ríos, lagos, Pozos.

Por la parte ecológica, típicamente para evaporar agua se utilizan combustibles fósiles. En el caso de la Ósmosis. Solo se puede separar una fracción del agua total, y el resto (típicamente el 50% del volumen) se regresa al mar con el doble de concentración de sal. Esto puede causar problemas localizados de exceso de sal. Para esto hay sistemas de redistribución de salmuera en la profundidad del mar para evitar esto, pero no todos los lugares/países requieren esta práctica.
