Nothing nowadays excites artists like 3D pens do. But be sure, they are not the only ones using this awesome invention. 3D pens have infiltrated quite an array of sectors, and the frenzy does not seem to be stopping. 

Check this incredible buying guide by Rabbit Reviews to help you choose the best 3D pen if you don’t have one. Meanwhile, let us explore the users of 3D pens.

Who uses 3D printers and 3D pens

1. Artists – This definitely had to be the first in this list. Artists use 3D pens to create 3D art objects that can be placed in houses and offices for added beauty. Such objects can be anything like a dairy cow, pregnant woman or an aeroplane. And remember artists not only do this for beauty – they use art to express ideas and concerns in the universe, for example racial injustice
2. Teachers – The education sector in many parts of the world has been ridiculed for being more theoretical than practical. But however teachers may try, it sometimes proves impossible to get practical. After all, how would you expect a teacher to take the kids to the pyramids of Egypt for their eyes to see? Modelling the pyramids using 3D pens is quite a wise approach.
3. DIYers – This refers to anybody who enjoys carrying out household tasks such as decorations and repairs without employing a professional for the job. If the plastic pipe supplying water to the kitchen leaks, the diyer quickly fixes the defect with a 3D pen. Their homes are likewise never dull. They easily pimp the interior with creative pieces using 3D pens. 
4. Industrial manufacturers – before a product is produced in bulk, factory managers would normally want to see prototypes for visual conception and critical analysis. Such prototypes are easily created using 3D pens
5. Kids – You must be aware that all children like exploring, and their curiosity just got better with the 3D pens. Whatever they create may not make sense to you, but it means the whole world to them.
6. The aged and the sick – Art is therapeutic – did you know that? Experts confirm that art is able to manage behaviors, process feelings, reduce stress and anxiety, and also boost self esteem. And 3D art capably does all this magic

Is Filament for 3D Pens the same as filament for 3D Printers

The answer is a big yes! The filaments are of exactly the same material, whether ABS, FLEXY, PLA, or PTU. The difference comes in the manner in which they are packaged. Filaments for 3D printers are usually coiled around a spool and are in bulk quantities. On the other hand, filaments for 3D pens are sold in smaller packages. 

What is the future of 3D printers and 3D Pens?

In the next few years, the use of filaments for 3D pens will be a thing of the past. 3D pens will be able to scribble through light-induced solidification of photoactive resin-based inks. This process makes use of the blue LED technology. As there is no heating of some filament, the pens will be safer for children to handle. The energy requirements will also be greatly reduced. All you’ll have to do is charge the pen and use it for an hour without any need to directly power it from the mains.

Working with electricity is fraught with dangers and dangers. Especially for electricians, the risk is higher.

In this article, I share with you, Dangers of using a digital multimeter.

The digital multimeter is one of the most important tools in an electrician’s kit.

However, once you have a digital multimeter. So how to use this tool to both ensure safety and satisfy the job.

Here are some notes when you are using a digital multimeter:

1.Have you have chosen the right digital multimeter?

That is, your multimeter is rated for the voltage you’re planning to measure.

It could happen like this: One fine day, you were testing three-phase electrical equipment with voltage, the operations were correct, suddenly there was a clap of thunder. your multimeter will flash. Luckily you’re okay, but your watch is broken. You are very surprised. But that is overvoltage transients.

Transient voltage is a sudden change in the voltage of the electrical system, due to:

The lightning spread.

Internal voltage transitions: such as switching devices such as motors, circuit breakers, transformers, or a sudden load change that changes voltage in a short time.

therefore, manufacturers have produced multimeters that comply with the following two criteria: voltage level and queue rating.

• Voltage level: Probes and meter withstand the voltage to be measured.
• Rated rating: Probes and meters withstand voltage transients for a given time.

The gauges are evaluated by CAT rankings (CAT II, CAT III, CAT IV).

CAT VI:

• Three-phase at utility connection, any outdoor conductors
• Limited only by the utility transformer feeding the circuit
• ›› 50 kA short circuit current

CAT III:

• Three-phase distribution, including single-phase commercial lighting
• ‹50 kA short circuit current

CAT IV:

• Single-phase receptacle connected loads.
• ‹10 kA short circuit current.

The CAT position seen on the meter is located near the probe plug.

Or you can take a look: the best multimeter that works for you.

2. Are your probes and watches still secured?

For electricians, insulation equipment is always important: insulating pliers, insulating screwdrivers, insulating mats, insulating gloves, insulating shoes … when performing power supply operations.

So is the multimeter, the test lead and the meter must be secure in use.

You must visually check whether the conductor or meter has external damage (physical damage):

• Is the probe wire scratched?
• Is the probe protector cracked?
• the meter is broken?
• Is the display normal?
• Is the connector between the meter and test wire loose?

No physical damage was found after an inspection. Continue to check if your watch is working:

Test the resistance (Ω): you take any resistor you know (100Ω) and turn on the correct Ω scale to see how much it is, can give such an approximate value as well.

Similar check voltage and current: including AC and DC, but you must switch its correct scale.

Risks are present during electrical testing, so make sure your multimeter is always best.

3.Is this mistake on your own?

• Measure the voltage but the scale on the meter is still in the Ω position: damage the meter.
• This is actually the case most often you pay attention to.
• Your watch broke the fuse in the past, and you replaced it with another one. its example is exactly 10A but you replace only 2A only. It will not be enough capacity.
• Have you ever been measuring Current (A) that you passed to measure voltage (V) yet? Remember to move the scale from A to V and switch the jack properly.

Summary:

Using electricity meters safely and effectively is a very essential skill.

Hopefully, this article can help you make better use of the digital multimeter.

A good tent plays a very important role in outdoor excursions. If you are planning to go on a weekend trip, please refer to this article to share your experience choosing a tent.

Some of the typical effects a tourist tent can bring to you:

• Rest after all day exploring, picnicking. Especially with long trips.
• Help you get deep sleep after a tired day.
• Prevent from rain, dust, dirt when a sudden rain comes.
• Avoid the attacks of wild animals, and also insects, mosquitoes, centipedes …

5 Tips to Choose the Right Camping Tent

1. Consider the price that is appropriate

Good tents are often expensive, which everyone knows for sure. However, do you need to buy a tent at a hefty price? This depends on the situation of each person.

If you’re new to camping for the first time and aren’t sure if you will continue camping much in the near future, choose mid-range tents with average price and quality. With this tent, the ability to withstand rain and wind is not high, so you should not choose campsites with extreme weather conditions, wet, stormy.

After a while, if you want to stick with your camping hobby, you can consider selling old tents, buying better quality new tents. If you regret exchanging tents, for the first time you can borrow or rent a tent.

2. Tent size and weight

Each tourist tent clearly states that it is a tent for some people (2, 4, 6 …). However, the size of the tent is usually calculated to fit the human body to minimize the weight that a person must carry.

So, if you travel 2 people and choose tent type 2, you will certainly feel uncomfortable because the tent is not comfortable enough in both horizontal and vertical, not to mention backpacks, furniture. In fact, 4-person camping tents are suitable for only 2 adults and 2 children.

If your whole family or a large group of friends often travel together, you should consider buying a large family tent.

Also, remember that tent size is proportional to weight, so the bigger the tent, the heavier you have to carry.

3. Tent shape

Of the four basic types of tents are A-shaped tents, umbrella-shaped tents, dome-shaped tents, and walled tents, the A-shaped and umbrella-shaped tents are handy ones with a size that fits and is easier to remove and install.

4. Double layer tent or single layer?

Double-layer tents are thicker, have a waterproof layer, better rain protection but are heavy and suffocating if the weather is hot. The single-layer tent is poor in water resistance but is softer and more breathable. So, depending on the destination you choose to choose a single or double-layer tent.

5. Other factors

Check zippers and tent doors carefully before purchasing to ensure smooth zippers, tent doors and vents properly arranged on the tent, ensuring air exchange.

It is advisable to consult with friends who have experience before buying a tent. When you arrive at the store, ask the seller to open a tent for you to try. Before going on a picnic, you should open the tent to try and get used to it.

Final Words

Hopefully what I share in the article will help you choose a good cheap camping tent for a great experience on the trip.

Top 5 Tips to Choose Right Darts

 Tip 1: Choose the right materials

The higher price the materials, the more durable the barrels. There are three main materials used to make barrels with different prices, including tungsten, nickel, and brass.

Tungsten is chosen by many professionals because it is a dense metal so the darts can be smaller and easier to control. In contrast, Brass is the cheapest material. Darts that are made from this material often depress most people when holding them because they are bigger.

 Tip 2: Choose the right tip darts

Before buying darts, you need to ask yourself if you like to play darts on bristle, electronic or flexible dartboards. There are two kinds of tip darts, steel and soft. Soft tip darts can be used in all kinds of dartboards, but it will be a great match with the plastic one. Steel tip darts are usually used with bristle dartboards, cork, and paper.

Tip 3: The barrels

This might be the most important part of a dart. You can imagine it like “the body of the dart”. Its weight can make the darts go higher or lower. If you feel like the darts always go lower than where you aim, then you will need a lighter one. And if it always goes higher than you aim, then a heavier one will be what you need.

 Tip 4: Dart flights

Dart flights are important because the right dart flights will keep your darts stable on their ways to the dartboard. There are a few things to be concerned about, but the most important ones are the size and the materials.

Bigger and heavier darts need bigger flights and vice versa. Nylon flights can perform differently compared to dense plastic flights. Nylon flights are used by many people because they are the most durable ones. Harder flights are stiff but you cannot fix them when they are broken.

 Tip 5: Your budget

You should care about the prices of the darts to make it the best fit for your budget, and the best fit for your intention of playing darts. If you just feel like you are interested in playing dart without any future professional plan or the real desire, then the cheaper ones will be better.

Many people buy new darts and get bored after a few days or weeks, so you can test yourself by playing the cheaper ones for a while to know more about your feeling toward this sport. After playing it for a while, if you feel like your heart is really into it then you can upgrade to the professional ones.

The prices of darts can be as little as $30.00 or smaller and can be as much as $200.00 or more. Make sure that the one you choose is a good fit for your budget.

Conclusion

Above are 5 tips to choose the right darts. Those tips will help you find the most suitable darts. It is recommended that you pay attention to all parts of the darts listed above.
