Coco Montoya @ Lipe Guitars USA (Winter NAMM 2009)

This video was filmed at the Lipe Guitars booth at the Winter NAMM 2009 show and features Coco Montoya playing a guitar hand-built for Coco by master luthier Mike Lipe of Lipe Guitars USA. The guitar is unique in that it is a left-handed body with a right-handed neck and strung right-handed. Coco is left-handed but plays guitar "upside-down" right-handed (like Dick Dale). www.lipeguitars.com The amp is a "Baby Will" 18 watt lite2b Valve Junior Conversion especially made for the NAMM show by Simon Higgs (particle). Details of the VJ conversion can be found at Wattkins Amp Forums www.ppwatt.com (Push-pull tube amps) http (Single-ended tube amps) Note: The background noise at the show was fairly loud, so the audio is not perfect. We couldn't turn the amp up full because, even at half-volume, we kept getting busted by the Sound Control guys with the db meters. :-)

Ionic Air Purifier Review - Efficacy & Efficiency Tests

Ionic air purifiers exist to combat airborne contaminants that are invisible to the human eye. They employ beneficial reactive agents that are also invisible to users. How then shall a user know if the purifier is doing what it claims or just burning electricity? A good place to start would be a properly conducted review. A quality review must begin by focusing on user safety. Safety, which can be further classified into 2 separate categories, has been covered at length in this author's 2 articles on EzineArticles.com.

An ionic air purifier review must also include 2 other equally critical criteria:

(1) Efficacy Test - the purifier technology, firmly grounded in sound scientific theory, must be proven to work in a laboratory;
(2) Efficiency Test - the lab-tested purifier technology must be successfully transplanted into an appliance that replicates the same laboratory results in the users' setting at home, in school, or the workplace. Such demanding tests require substantial resources quite beyond those of the ordinary user. The Efficacy Test must come under the purview of a laboratory and even then, a GLP-certified laboratory.

GLP, which stands for Good Laboratory Practice is a set of principles formulated by the OECD to ensure the generation of high quality and reliable test data. The Efficiency Test is even harder to achieve with consistency and objectivity since it has to be conducted on user locations. Notwithstanding these obstacles, an ionic air purifier review must include a proper assessment of the efficacy and efficiency of the ionic air purifier. Proper tests include most, if not all, of the following characteristics:

(1) A controlled experiment

• This involves the rigorous testing of an unproven statement known as a hypothesis;


• A clear concise iteration of the science behind the technology;


• Control check - the effects of an operating ionic air purifier in a room must be matched against the effects when there is no purifier present;


• Replication - the experiment must be capable of peer review, preferably by an independent third party of some authority;


• Replication - the experiment must show the same results at different times where the conditions are identical;


• Replication - different purifiers of the same model must produce very similar or identical test results;

(2) Randomized double blind testing standard - this is the highest standard of medical clinical testing where both the researcher and the test subject do not know whether they are in the actual experiment (where the ionic air purifier is functioning) or the control experiment (where the purifier is not functioning);

(3) A proper testing location - where all known variable factors that can affect the performance of a purifier can be controlled e.g. room size, temperature, humidity, inclusion or exclusion of ambient or outdoor air;

(4) Accurate measurements and recording - the effectiveness of a purifier can vary over time and distance, air flow speeds, consistency of instrumentation etc.;

(5) Proper specialized measuring equipment (images available at The Ionic Air Purifier Blog) is commonly required, such as:

• microbiological air sampler


• ozone tester


• positive & negative ion detector


• decibel meter.

(6) Proper analytical tools and skills - these are required to accurately measure and document the test results before and after the experiment e.g. analyzing mold cultures before and after ionic air purification;

(7) Integrity of the testing staff is critical so that the test results are professionally documented and reliable. Where substantially all of the above procedures have been performed on a purifier by a GLP-certified laboratory, the results of the efficacy and effectiveness tests will form very reliable inputs to an ionic air purifier review. It is the mission of this blog to obtain such test data on as many purifiers as possible, with the goal of producing reliable, objective ionic air purifier reviews for the benefit of all users.

Cabinet Panel Cooler As the Best Cooling Option For Electrical Enclosures

For those who have used the cabinet panel cooler for cooling electrical enclosures would vouch for its affordability, and reliability. Moreover, today it is known in almost all industry sectors for its easy installation options. Accordingly, you would find a wide range of up-to-date models to suit the requirements of the various sectors of the current industries.

The other cabinet cooler advantage is that unlike the varieties that were available earlier, the new ones are just as quiet as an air conditioner. This nullifies all its detractors that did not use it earlier because of high noise levels. In fact, nowadays there are technologically advanced cabinet panel cooler for electrical panels that have decibel levels which is about the same as normal human conversation.

The new generation cabinet varieties also feature an integral mechanical thermostat to conserve energy and maintain the desired enclosure temperature. A knockout hole in this cooler keeps the control panels cool, clean and protected. However the best thing about these coolers with vortex tube is that they help in saving energy as they are thermostatically controlled to relieve you the pain of paying heavy electricity bills. They cool without Freon or other refrigerants like air knife, thus enabling you cooling options almost for free.

Most of the recent models of panel coolers for cabinet cooling come in compact sizes and hence fit even the tightest of spaces making them quite user friendly. The absence of moving parts makes them reliable and maintenance free solutions for users from all the different industry sectors. However, before getting any of the models of cabinet panel cooler, it is very necessary that you get only the ones that are UL-listed for better performance and safety options.

Apart from cooling electrical enclosures, the cabinet panel cooler is also used for cooling electronic controls, machining operations, soldered parts, gas samples, heat seals, many more factory and industrial applications.

The Sound Pressure Level Meter and You

If you've ever lived in an apartment complex, or in a college dorm for that matter, it's almost a given that at some point, you've had to deal with noise neighbors. Loud footsteps, late night vacuuming sprees, noisy parties and of course, sound systems loud enough to break your windows. And if you're like me, you've wondered, "Don't they realize how LOUD they're being?" And while it is true that many people do realize and simply don't care, some are honestly ignorant of the amount of noise they and their sound system are making.

Many people simply have no idea of how incredibly loud their home theater audio systems are or how much that level of noise can both distort sound and damage hearing. And if you're the proud owner of such a system and trying to attain optimal listening loudness, that can be a real problem-especially since high-precision measurement instruments can be utterly expensive, insanely huge and annoyingly hard to find. Fortunately for the discerning domestic audiophile, there is a solution: a sound pressure level (SPL, for short) meter. This handy, portable, lightweight, easy to use and generally affordable measuring instrument can help you get the most out of your aural home entertainment experience.

An SPL meter is of a handy size, usually about six inches long and two inches wide, and it has a corresponding weight of about six ounces. But don't let its size fool you-this little gizmo can be the answer to your home theater audio challenges. Here are the facts. The decibel, or dB, is the unit used to measure sound. On an SPL meter, both the dB output of a system and the effect of that output on the human ear are measured. This dual monitoring system allows the listeners to adjust their systems accordingly, and there you have it: a home theater audio system perfectly adjusted for maximum listening enjoyment. You'll be able to listen to car chases and explosions as loudly as possible without the annoying side effect of damaged ear drums.

This is, of course, a very basic description of the SPL meter's abilities. There are slightly different settings that should be used for specific situations, such as when measuring the sound of a HiFi system as opposed to a generic one. Still, the basic principle is the same. Just turn on your system, pick up your meter and point and shoot. Done deal.

As mentioned, SPL meters are easy to find and can be purchased at most electronics stores. Radio Shack carries them, as does Circuit City and a number of online stores like ProGear Warehouse and Elusivedisc.com. Some are more expensive than others and some have better accuracy and wider frequencies. But the most basic model is usually sufficient for the average home theater audio system owner. So if you want to watch your movies with the surround sound turned up as high as possible, but you still want to be able to hear your friends twelve months from now, invest in one of these. Your ear drums and your neighbors will thank you.
