Pot Grinder - Top 3 ReviewsGetting the best herb grinder shouldn’t that be difficult when you thoroughly look and study each brand and what suit you. Using herbs is essential especially for medical related purposes. You want all the enzymes to be crushed down so every tiny bit of pieces of your bud will be able to extract its best parts. Not only you’d want your material to be cut down to wee beautiful pieces, but you also want an herb grinder to be able to shred and do its work for a long time without breaking down. So these are your important factors to consider before buying the best herb grinder for you.

One type of an herb grinder is a two piece material. Basically, this crusher only has 2 compartments, one is for the placing of the herbs and second part is where the crushed herbs slid to. SPACE CASE Grinder Magnetic is a two piece herb grinder made from titanium. The titanium material used for this pot grinder is non stick and uses a process so called aluminum anodizing. Aluminum anodizing is used to thicken the metal layers of the grinder hence making more durable and more resistant to damages. The more durable your grinder is, the longer and effective you can use it.

If you can find a 2 piece grinder, you can also find a 3 piece of it. Aluminum 3 Piece Tobacco Spice Herb Revolver Bullet Grinder is sold online by CZ-Sky. This 3 piece grinder is designed like a gun’s revolver which makes grinding more fun. The top most part of this herb grinder is where you’ll do the twists and turns. The middle part has a screen and the third part catches your grinded herb which serves as your storage. You can grind and stack up about 2 grams into this Revolver Bullet Grinder although some people find the grind result a bit too fine.
Lastly, a review for a 4 piece grinder called Santa Cruz Shredder. Like Space Case, Santa Cruz Shredder also uses anodized aluminum so expect that the material is durable and can stand against damages for a good time. The top most part which has the teeth cut and shred the weed into good tiny pieces in both ways as it was designed. It’s also designed to be twisted easily especially for people who suffer from wrist pains. There isn’t too many waste to throw away as it could catch and save every piece you intend to grind and use.
Herb grinders’ users can pick whatever they want as they have their own preference. Some would rather have the two piece as it can be light weighted.

metal detectors groupMetal detectors are helpful in uncovering all sorts of metal items, including coins, jewelry, and even gold. It’s quite fascinating to learn how the devices work. Lenz’s law of electromagnetism states that at the time a conductor drops within a particular range of an alternating magnetic field, it makes its own oscillating field. That goes against the primary field.

A magnetometer is able to detect the changes within the overall field. It signals when a conductive object is close. It’s usually a bit of metal. Metal detectors’ ranges vary from a couple feet for the tiniest coils, up to 10 feet (3 meters) for 12-15-inch coils.

The key part of a working metal detector is the eddy currents created by conductive objects inside the environment. It’s like pushing a canoe paddle through a body of water. It can cause small vortices to show up on the surface of a lake, for example when the electrons contained in metal create an oscillating field.

The best results are produced with frequencies ranging from 3 to 20 kHZ. Meanwhile, some of today’s best metal detectors allow users to adjust the alternating field’s frequency.

Meanwhile, a newer type of metal detector utilizes a kind of tech known as pulse induction. This type of metal detector hits the ground with huge electromagnetic pulses, and detects the amount of time needed for voltage to drop to ambient levels. When there’s a conductive object underneath the ground, it will take longer for the voltage to drop. Its’ a tiny effect, but today’s sensor can detect it well. This particular method has particular advantages over standard metal detectors. They include the capability to pick up objects below the “black sand,” which is highly mineralized.

Metal detectors have many applications. The most critical one is the ability te locate mines or explosive devices that are buried right below the ground’s surface. On nations where mines still exist from past wars, people are asked to use metal detectors when they talk through unknown areas that were at risk for land mines. The gadgets are able to save many people lives.

Metal detectors can also be used for finding various types of so-called “buried treasure.” That includes coins/relics that were buried years or even thousands of years ago. Metal detectors can even pick up objects that were lost a couple days in the past. It’s an excellent task for a hobbyist.

Very low frequency (VLF) metal detectors work on the scientific principle known as conductivity. They locate any metal that has a conductive surface with a distance of 18” to 2 feet from the ground’s surface. A signal can be heard since an electromagnetic field is created and then flows out into the area away from the device’s search coil. As the electromagnetic field enter the metals’ surface, small electrical currents known as eddy currents flow into the metal’s surface. The eddy current then creates electromagnetic fields that radiate in all directions within space. The currents that radiates up towards the search coil winding are detected. A lower voltage then is fed into amplifying wires.

band sawsThe band saw is a machine that utilizes a blade that consists of a band of toothed metal that rotates on the opposing wheels in order to cut the material. They are highly used in lumbering, metalworking and woodworking, but there are other materials that it can cut with. The advantages, according to scrollking.com of using this machine includes the uniform cutting which is the result of the even distributed tooth load. It even has the ability to cut curved and irregular shapes like that of a jigsaw puzzle. Most of the band saws come in two wheels that are connected with a chain or belt that rotates on the same plane, one that is powered.

But did you know that there are things that people did not tell you about working with a band saw? Here are 7 of these things that you might have not known before.

  • Band saws are highly used in woodworking, but they are also used in metalworking and even cutting meat. The ones that are used for cutting meat uses stainless steel that comes in easy cleaning features. Its blades are either made with scalloped edges, plain or heat treated tips. As with metal cutting, it comes in horizontal or vertical designs. For timber cutting, this work makes use of very huge band saws in order to rip through lumber. This machine is preferred over the circular saws when it comes to ripping because it is able to accommodate timber in large diameter and its smaller cut size, thus resulting into less waste.

  • What can a woodworker do with having a good band saw? Some experts point out at the resaw feature. This actually means that sawing the board through its width. It is just like cutting through a long roll in order to open up for the sub sandwich.

  • You can also reset the board’s edge when using the band saw machine. Instead of just accepting the board’s edge as it came from the mill, it is oftentimes better to re-cut the material’s edge to more gracefully align its figure together with its length. An example for this is probably prepping multiple boards for putting it up on the tabletop, wherein you want its figure get coordinated among the other boards.

  • To gain further control of the figure and grain of the wood, you need to reset the face of the board. Sounds difficult? An example of this would be involving a very sophisticated project, wherein it involves maximizing the wood’s ray figure into certain species. And this is done by sawing in order to reorient the board’s face to its annual rings. The band saw is an excellent kind of sawing for this case, which elevates the quality of the work far more than ordinary.

  • There are various design possibilities when you use the band saw in working with thick veneer. The board is then sawed into multiple thin slices in which it can then be utilized for matched set pieces, like for curved doors or the front faces of a drawer.

  • The band saw is considered the most practical machine in sawing thin laminates which composes bent lamination. This is a technique that can expand the design into different possibilities. Just like working with veneer, the laminates are then sawed in successive manner from thick boards like it was done in making ash laminates. Each of them gets glued together in order to produce its curved part in the furniture.

  • Lastly, it is about processing small logs. If you have a band saw at home or at your little workshop, it can be used as your own mini mill in order to cut through small logs, like those that you see at your backyard. This can be very exciting and fun way in discovering the treasures of nature that you can’t find anywhere else.

science for kidsSchools, particularly in teaching the sciences like biology and chemistry, requires the need of various tools in the study of the said subjects. One of which is the microscope which is an instrument used in viewing objects, big and small alike, to study its composition.

Second is the plastic microscope which is a child-friendly microscope. However, they can’t provide good image and can’t focus to images easily. Third is binocular and monocular microscope. By the name itself, you can already tell what it means. Basically it is just about the number of eyepieces. In this manner, binocular ones are more effective since it can suit gets with bigger eyes. One more is the dissecting microscope which is used for viewing solid object. Lastly is the latest trend in the line of microscope – the USB or digital microscope. This is an advance type because it enables the user to capture images and even videos in real time mode. Actually, there are a lot of microscopes in the market but these are the most commons purchased for kids.


After determining the different types of microscopes, you should also take into consideration the usage of the one you want to purchase. Of course, if you to have to use it for specimen that requires more preparations like blood samples, it is then better to purchase the compound microscope. On the other hand, if there is a need to capture images for recording purposes, then the USB microscope can become handy. Also, in connection to usage, there should be ease of use in order for your child to maximize his or her work with minimal observation.


Yes, it is indeed important to recognize the interest of your child. But you don’t need to risk further and go for the expensive ones. As a rule in purchasing, it is a big MUST to research first for the product before buying in a rush. Don’t jeopardize the quality over the price and vice versa.

In general, choosing microscopes for kids takes a little research. Of course, you don’t want to get disappointed after you purchased one. For example, instead of buying the plastic microscope or the so called “toy microscope”, why not spend a little more for the metal one. Or, if you consider safety, then you should go for the plastic one is more child-friendly and easy to use. Researching also comes in handy in weighing the pros and cons in buying a microscope for your child. Most of all, kid microscopes are not only for child’s play. Always remember that it is for your child development and interest that matters. It is important that your first priority is to nurture your child’s curiosity in things about the environment around him or her.
