Texas Instruments Ti-83 Plus Calculator

images3

Calculators have shrunk in size and increased in price as consumers have sought out devices that do much more than simple arithmetic. Texas Instruments has their TI-83 Plus model which helps students with their Physics, Biology, Algebra, and Pre-Calculus classes. We’ll examine why this model is so popular with today’s classroom students.

Back in the 1970s, the slide rule gave way to calculators in many classrooms across the nation. Texas Instruments led the way as almost every student owned one of their models. Today, Texas Instruments [or, TI] continues to produce calculators and their TI-83 Plus calculator leads the way.

So, what sets this particular model apart from others? Well, it is pocket-sized, comes with 12MB of memory, does tons of math problems including statistical tests, has a complete alphabetical keyboard, and it can run programs to name a few. Still, if you are a Calculus student it doesn’t do Calculus. However, you can bring the TI-83 Plus along for standardized tests and college admission exams.

The device runs with 4AAA batteries, so you need to make sure you are fully charged before you start your tests or at least carry spare batteries with you.

The TI-83 is not cheap as you will have to pay about $100. for a new one. Expect to pay a lot more if you purchase one through your university’s bookstore; shop online to compare prices too.

The TI-89 may be a better option, especially if Calculus is in your future. Shop and compare and make sure that the model you want provides the calculations you need.

In all, the TI-83 carries on a long tradition of excellence for Texas Instruments. Sharp, Casio, and Canon are chief competitors to T.I., but judging by the TI-83 you will find what you need from the people of Texas Instruments.

How To Make A Jingle Bells Instrument To Accompany Christmas Carols

images20

Fun to make and a great accompaniment to the classic carol Jingle Bells, just shake to the beat. Who would have thought that rubbish and junk could sound so festive?

Al you need to make a jingle bells musical instrument is…
16 metal bottle caps, paint, brass nails, sandpaper, hammer and some scraps of wood.

First paint the out side of the bottle caps a nice metallic colour. Spray paint is quick and easy, but applying paint with a brush is just as good.

When the paint is dry, use a large nail and hammer to make a hole in the centre of each cap. Have the cap sitting face up as it would do on the bottle, that way the rough edges are created on the inside of the ‘bell’.

The bells are fixed to a piece of wood, roughly 2cm by 3cm and 28cm long. Give the wood a good sanding so that it doesn’t have any rough surfaces. You could paint or varnish the ‘handle’ if you wish to.
Working on one side of the handle at a time, attach the capes in pairs with the insides of the caps facing one another. Push a brass nail in the holes of the caps and offer it up to the wood.

Place the first set of bells 5cm away from the end. Don’t hammer the nail in too far into the wood. The bells need to move freely on the nail and clatter together.

The second set should be 8.5cm away from the end.

The third set should be 12cm away from the end.

Now turn the handle over to attach bells to the other side. Use scraps of wood to prop up each end of the handle so that it is clear off the workbench. Otherwise you will spoil the bells that you have already attached.

Add bells in pairs in the same way as you did on the other side, but this time the first set of bells 1.5cm away from the end. Add the other sets of bells so that they are level with the bells on the other side of the handle.

Then turn the handle over to attach the remaining set of bells. Again use scraps of wood to prop up the handle.

And there you have it, a set of jingle bells. Young children should be supervised when playing the jingle bells.

If you find it difficult to obtain bottle caps, you could ask an adult to approach a public house or bar, they have no use of the caps. You could also maybe write to a local brewery requesting some bottle caps. Alternatively look in the winemaking department of Boots or Wilkinsons for new bottle caps.

Varnishing the Body of a Stringed Instrument

Written by S. Van Dyck

A good violin, viola or cello varnish can play an important role in perfecting the sound quality of an instrument. The varnish applied by Stradivari to his violins is still believed by many to be the secret the their phenomenal sound. Whether oil or alcohol-based, violinmakers prize their varnish recipes as one of the most important elements of the violinmaking process.

Before applying any coatings to the instrument, the white wood can be given a tan by exposure to sunlight for a period of several days to several weeks. Aging the wood brings out the color and visual character of the wood through oxidation and ultraviolet light.

When the wood has received the desired look, the next stage is applying a -ground- coating. A violinmaker may prefer to apply a primer or sealer first. While also darkening and deepening the wood’s visual depth, the ground coating strengthens and protects the instrument even after the varnish has worn off. Many recipes for the ground coat exist and typically this is a tightly held secret.

Next, the instrument is ready to be varnished. Many recipes exist; most consist of sun-thickened oils such as linseed, lavender or walnut oil combined with oxidized resins such as amber, dammar, balsam and shellac. Alcohol can also be used as a part of or in addition to an oil base. The mixture is left to sit for up to a week, being stirred a few times a day until the lac no longer sits at the top. The mixture is then boiled, cooled and boiled again, then filtered for impurities.

Adding color to the varnish mixture can help to bring out darker, richer tones, if the varnish mixture is too light. Coloring agents, or -lakes,- include turmeric and saffron for a yellow tone. Sandalwood and pernambucco bring out a redder tone. The varnish is then applied in many coats depending upon the thickness and consistency of the varnish. The varnish is allowed to dry in the sun between coats. Touch ups can be added if there are areas needing additional coating. The instrument can then be lightly polished using a soft cloth with alcohol and mineral oil and or polished out using pumice powders.

Which Music Instruments Can You Learn At Any Age

images21

Many of us are captured by music, so much so that music has become an important part of our lives. At some point in our lives, many of us want to learn to play a musical instrument. We may thing that taking violin lessons or guitar lessons is fun. Or we may fantasize that we can turn professional and perform on stage. Well, learning to play a music instrument like the ukulele, saxophone, guitar or violin may turn out to be more than a hobby as many people have gone on to teach once they have mastered the instrument.

It does not matter if your child is looking to learn a music instrument, or if you are trying to pick up the skills of playing violin or playing guitar at middle age. In this article, I will outline four music instruments which are relatively easy to learn at any age:

1.Ukulele

The ukulele is probably one of the easiest music instrument to play. Unlike the guitar, it has only four strings. The size of the ukulele is also portable, the smallest being the Soprano Ukulele followed by the concert and tenor ukulele. Even a child as young as four years old can take ukulele lessons and learn to play the ukulele by strumming simple chords.

2.Guitar

The guitar is currently one of the most popular music instruments around. Many young children and teenagers aspire to play the guitar at some point in time. The guitar is also relatively cheap, and you can opt to learn the acoustic guitar or the classical guitar as a start. Most teenagers nowadays prefer to learn the acoustic guitar to play pop songs. As with the ukulele, you will need to master how to strum chords for the guitar.

You also have the option to learn to play the electric guitar. However the electric guitar costs more than the acoustic or the classical guitar so if you are on a budget I suggest you start off learning the acoustic and classical guitar.

3.Violin

The violin is as popular as the guitar and can be learnt at any age. Violins come in many sizes, starting with 1/16 size for three year olds, to 1/8 size, size, half size, size and full size. The most important step in learning the violin, no matter what age, is to master the proper bowing and fingering techniques.

4.Piano

The piano can be learnt from age five onwards. The most important aspect in learning the piano is to practice constantly and master the playing techniques.
