Casual Articles - My Overhead Projector Has What?
When innovation shifts the mindset of an industry, those companies designed to construct and distribute the older model are typically averse to adopting the new shift. This aversion allows new players into the industry often times leaving the industry leader under the old mindset, lost, scrambling, or simply, tryi

School BusesWhen approaching a school bus: Slow down; If the amber lights are flashing, the bus is about to stop; If the red lights are flashing, the bus is stopped; In many states it is against the law to pass a school bus with flashing red lights and/or an extended stop arm.Do not upset schoo
My clients often say to me “You think my Overhead Projector has a bad diode, what’s a diode?"
Let's start off with quick lesson about diodes, sometimes referred to as rectifiers. Diodes are semiconductor devices which might be described as passing current in one direction only. You can even find diodes used in some of today's LED (light emitting diode) Flashlights. In the case of Overhead Projectors, diodes are used to regulate voltage.
With the advent of today's halogen projection lamps used in most Overhead Projectors today, a special operating voltage is required to operate these lamps. Generally the voltage is around 82 volts. Because the voltage at the AC outlet where you plug your Overhead Projector into is 120V AC, a diode (rectifier) is used to regulate this line voltage to the necessary 82 volts.
Unfortunately for the end user, when the diode in their Overhead Projector fails it can be quite costly. Most end users don't realize that this component even exists. When it fails, in most instances the diode becomes a short circuit. This short circuit allows the line voltage of 120 volts to go directly to the projection lamp which only requires 82 volts to operate. In our repair shop we refer to this as scorching. The end user assumes that they have a defective projection lamp, so another lamp is placed into the projector. This process sometimes continues on with several lamps being replaced before the end user realizes that it is not a defective projector lamp causing the problem.

The main purpose of a headline is very simple. You want to grab the attention of your ideal prospect so they’ll read the next sentence in your advertising copy.Easy to do. Right?Well... not so fast.It’s possible. That’s the good news. But you have to do your homework first. There are books

Sooner or later, most business owners need to look for outside financing. Whether it’s a line of credit with a bank to handle predictable cash crunches or a significant capital investment to improve plant and equipment, virtually every business will need access to additional funds at some point in its life.
The diode is a fairly inexpensive electronic component to replace and in most cases is easily accessible. The only caution I must offer here is that diodes are directional and must be placed back into the electrical circuit a particular way. If you are not familiar with these types of components the repair should be left to a professional electronic technician.
