Building A Projector

To learn how to make a DIY smartphone projector, first, you are going to get a piece of plywood. Decide how big you want your projector to be, then measure it, mark it and cut. Remember, your magnifying glass will act as a lens so plan the size of your box accordingly.

Next, cut the handle of the magnifying glass and trace around what is left, on the wood, where you want your lens to be located. Cut out the hole in the middle and use your jigsaw to cut out the spot where the magnifier will go. Make sure that it fits in the hole nice and tight. It should fit flush so that no light is escaping from your homemade projector.

After that, glue and nail your pieces together, creating your projector box. Make a lid if you haven’t done so already. The next step is to paint the inside of the box so that it is as dark as it can be inside. Glossy black paint will be perfect. You can also line it with black paper. Your phone is the light source after all. You can use some foam boards to hole your smartphone in place.

That’s it. You are done. Set your phone inside the box and start movie night! You can use a projector screen or just a blank wall. You can have an outdoor movie night or indoor home entertainment. You now have a projector for your smartphone.

Air Purifier vs Humidifier – Which Is Best For You?

If you haven’t used an air purifier or a humidifier, you might be wondering what these things do. What are their differences? Can you use them in the same room? These home appliances can be confusing, but we are here to clear the air. Pardon the pun. As we look at the air purifier vs humidifier issue, we will shed some light on these mysteries. Once you learn how they work, you’ll be comparing models like the Honeywell vs Dyson air purifier in no time. 

How do these machines differ and how can they help you?

Air Purifier vs Humidifier – Is One Better Than The Other?

These days many of us use an air purifier in our homes to clean indoor air, as well as humidifiers. But how are they similar and how do they differ? We are going to take a look at how each of these machines works so that you can understand what they do and how they benefit you.

Both improve the air in your home, but in different ways and will help those with respiratory or sinus problems, but each offers a different kind of relief. An air purifier will clean the air of allergens and pollutants, helping you to breathe easier, while a humidifier will add moisture to the environment, helping with problems that are caused by dry air.

Air Purifier vs Humidifier – What They Do

An air purifier uses fans to suck your homes air in, where filters and other methods are used to trap and remove airborne contaminants and other irritants in the air. This can have many benefits for allergy sufferers as it removes air pollutants like dust, pollen, pet dander, mold spores, cigarette smoke and more. Many allergy sufferers use an air purifier for mold with great success as they help prevent asthma attacks, other respiratory conditions, and sore throats.

Humidifiers are great for adding moisture to the air which helps with conditions that are caused by dryness. Many people suffer from respiratory problems due to dry air. The humidifier adds moisture and those symptoms caused by dry air begin to ease up, giving your nasal passages a break.

One cleans your air, while the other moistens it.

How Do Air Purifiers and Humidifiers Work?

Air purifiers have one job and that is to remove harmful contaminants from the air. To do this, it sucks air in and runs it through a series of filters. Often a true HEPA filter, which can capture particles as small as 0.3 microns. True HEPA filters are 99.97% effective at removing contaminants from the air that trigger respiratory problems. A HEPA air purifier simply removes more bad things from the air, improving the indoor air quality. There are a few different types of air cleaners, but all cycle air in and clean it using various methods.

A humidifier also has a single job and that is to put added moisture

Molekule vs Dyson Air Purifiers – Which Cleans Your Air Better?

Does pollen have you down? Do you suffer from asthma? Those shopping for the good air purifier have no doubt already checked out these two popular models, so I thought I would compare the two so that you can see what their strengths and weaknesses are. So read onward as I compare Molekule vs Dyson.

How do these two models differ?

Molekule vs Dyson – Design

The Dyson air purifier sports a unique design in the world of air cleaners. It has the vent and filters at the base of the unit, while the top is an open bladeless ring called an “amp”. The large amp delivers better airflow and purification. The size of the amp differs between Dyson models, but as the amp size gets larger, it can pass more air through.

The Molekule air purifier has more of a typical design. Air intake happens at the bottom of the machined aluminum cylinder. The vents around the top push clean, purifier air into your home. It is very straight-forward.

Molekule vs Dyson Air Purifiers – How Do You Operate Them?

The Molekule air purifier has it’s a touch screen display on the top of the unit. You can use this to scroll through its various features and change the settings to where you need them. You can also control it remotely via your smartphone if you use the app.

The Dyson air purifier can be controlled by using the round display screen below the amp. It is pretty versatile as you can also use the remote control, the app or voice control (depending on the model).

Molekule Air Purifier vs Dyson – How Do These Machines Purify Your Air?

How do these air purifiers work? These two machines approach indoor air cleaning much like every other air purifier. They suck dirty air in, pass through air filters, and push the clean air back out through vents, now that it has eliminated most of the pet dander, dust, mold spores, dust mites, and other nasties. This is how your indoor air quality is improved. However, they do use different air filter types. Here is a helpful guide from the EPA.

The Molekule uses FECO filtration. (Photo Electrochemical Oxidation) This simply means that it uses a light-based chemical reaction to kill the air contaminants it encounters. Things like allergens and bacteria viruses first hit the pre-filter in order to trap larger particles. Then smaller particles hit the PECO so that the light can zap the particles. This is known as a uv 0r ultraviolet light machine.

Dyson takes a more typical approach to filtration using a HEPA (High-Efficiency Particulate Air) filter and an activated carbon filter. The HEPA filter takes care of all of the fine particles, while the other eliminates gases and odors. This is why the best HEPA air purifier models sell so well. Especially for those with allergies. Dyson keeps it simple.

How To Make A Pinhole Projector To View A Solar Eclipse

I don’t know about you, but whenever there’s a solar eclipse, I have always missed out on all of the action, simply because I didn’t know how to make a simple pinhole camera. Well, now I do know how to make one and I will be sharing that info with you. So let’s learn how to make a pinhole projector. These are a very primitive version of a home theater projector and that is an understatement.

Learn How To Make A Pinhole Projector

You need a pinhole projector if you want to safely view an eclipse. (You will still need to wear special viewing glasses before and after the moments when it’s totally blocked though, to protect your eyes.) Making a pinhole projector is so easy that a kid can do it. In fact, it is a project that is often created in grade schools across the country. It is a great way to view a solar eclipse without potentially going blind.

What You Will Need To Make A Pinhole Projector

In the simplest terms, you just need two things: an object with a pinhole in it, and something to project the image on. The easiest and cheapest way is to use two pieces of rigid white paper and poke a pinhole in one with a pin. You can use something like paper plates, white cardboard or heavy card stock.

How To Use Your Pinhole Projector Creation

Using your pinhole projector is just as easy as creating it. Now that you’ve got your piece of paper with a pinhole, Hold the piece of paper with the pinhole up and let the sunlight shine through it. You’ll use the other piece as a projector screen by putting it on a wall or on the ground. In this way, you’ll be able to see a projected image of the partially hidden Sun on that screen in a safe way.

Remember to have your back to the sun and look at the projection created by the pinhole on the wall, Do not look at the Sun through the pinhole. That will damage your eyes.

How Does A Pinhole Projector Work?

Pinhole cameras use what is called the camera obscura effect. You see normally light travels in straight lines. So when an object is lit up, the light will bounce off of it in a straight line. The pinhole in the paper lets a small amount of that light through, and an inverted image forms on the other side of the hole. They may not be one of our best projectors under a grand, but good enough for an eclipse.

Aside from being a safe way of viewing an eclipse, this eclipse viewer is also a fun and easy
