Monster Takes A Chainsaw To The Lowly Outlet Strip

Tuesday, April 24th, 2007

spokesguy You can file this device under “wish I’d thought of it first“. Monster Cable, the company known for its high end (and high priced) audio cable has released their “Outlets To Go Power Strip“, a stripped down, light weight version of the “found under every desk” AC power outlet strip. This device is designed for travelers who run out of outlets in their hotel room or airport boarding lounge, but don’t want to lug around a full sized outlet strip.

I came across this device while listening to one of my favorite podcasts, The Daily Giz Whiz from TWIT.TV. They review an interesting new tech gadget almost every day.

Monster has managed to use half the plastic and half the cable and sell the device for twice the price of the original. They tout their FlatProfile Plug and FlatWrap Cord (both trademarked names) as making this device the perfect tote-along for power hungry road warriors. That there is a need for this device is unquestioned. The $29.95 price (about 4 times what you’d pay for a standard 6 outlet strip at Wal Mart), is another matter entirely.

Monster has done an amazing job of using their branding strategy to convince people that a wire isn’t just a wire. There has been an ongoing debate for years in the audiophile community about whether Monster Cables, particulary their speaker cables, improves sound quality. Regardless of how you might feel about that argument, the Outlets To Go strategy has nothing to do with wire quality or audio signal flow improvement. It does, however, give them the power to charge almost $30.00 for their better mousetrap.

I usually agree with the opinions voice at The Daily Giz Whiz, but I’m afraid they are willing to pay too much for not enough.

How low will you go?

Wednesday, April 18th, 2007

fred looks right When you have a domain like buyextensioncord.com and it includes a toll free telephone number, you get a lot of questions. Taking the time to research customer queries has been a great way to grow our business.

Today, we got a call from someone who needed extension cords to use in large walk-in freezers. The cables he was using were freezing and could no longer be coiled. It was easy to understand his problem, but not quite so easy to find the solution.

If you have ever taken the time to look closely at an extension cord, you’ll see that there is a lot of difficult-to-decipher information printed on or embossed into the cable. This information tells you what environments the cable is designed to be used in and the amount of current that it is safely rated to carry.

Putting this info directly on the cable is required if Underwriters Laboratory is going to give the item its blessing as something safe for consumers to use. Here’s a useful link to safety info from UL about extension cords and how they are rated.

In doing a little research for this customer I came across a very nice diagram of how extension cords are made and the characteristics that give each type of cable its unique rating. Here’s a link.

It turns out that the info our customer needed is included in a 3-5 digit code found on all extension cords. The code is assigned by the National Electrical Code and the data in question usually starts with the letter “S”.

If you want to know a little more, click here.

Anyway, it turns out our customer is going to need a cable with a jacket specification of SJEOW. The “O” in this code means that the cable has a thermoplastic jacket (flexible at low temperatures) and the “W” means that it is rated for outdoor use. Extension cords with this rating will remain flexible down to -45 degrees F.

Maybe We Should Sell Car Batteries

Thursday, March 15th, 2007

battery bob You don’t usually think of car batteries as expendables, but it looks like that is changing. An interesting article in this weeks Wall Street Journal talks about how the demands of today’s electronic-laden cars are taking a real toll on their batteries. A car battery has traditionally lasted 3-5 years but the addition of power sapping devices like DVD players, GPS systems, heated cup holders and security systems has radically altered the life of these batteries.

The design of the auto battery is little changed in decades and what we ask these batteries to do was never imagined 10 years ago. It used to be that about the only thing that used power when the car was shut off was the clock. Now all sorts of items from the cooling fan to your cell phone charger continue to use power long after the car has been parked.

Experts in battery maintenance recommend that the battery be disconnected when the vehicle is parked for more than a couple of weeks. Better yet, use a device called a “trickle charger” to keep the battery charged up even when the car is not being used. These same experts warn that the biggest threats to battery life, extreme weather and harsh vibtration,can’t be avoided.

With the cost of a replacement battery sometimes exceeding $200.oo a little thought given to battery mainteance can go a long way.

Time To Change That Smoke Detector Battery

Thursday, March 8th, 2007

Tex Talks Daylight savings time starts this weekend. The clock is being set forward three weeks earlier this year and some confusion is probably in order.

One thing you don’t want to be confused about is the need to change your smoke detector battery. Using the time change as a reminder to change these batteries twice a year is a great idea, and the date change doesn’t diminish the need to attend to this important task. It takes just a minute and its easy to do.

Lots of new residential construction uses hard wired smoke detectors and some homeowners don’t realize that these detectors need battery changes too! The battery provides a backup in case there is a power failure. Quite often an electrical fire can lead to a quick shutdown of your electrical service, leaving the smoke detector without a fresh battery useless. Just because the LED indicator on the smoke detector is glowing doesn’t mean that the battery is good.

A battery that is no longer adequate for your smoke detector may still have enough power to use in other non-critical applications. Try it in some other device before throwing it away.

Just How Many Mic Cables Do You Need To Get To The Moon?

Monday, February 19th, 2007

mike2 I often joke that I have coiled enough cable to get to the moon and back. Turns out that I was exaggerating just a little. It appears that it would take about 30 million 50 foot mic cables just to get there. In case you were wondering, its about 284,000 miles to the moon.

Why this sudden interest in proving myself wrong? We’ll, I just came across a device that might have kept me from retiring from the sound business. It’s the Kaltman Cable Coiler. If this thing really works, it would be pretty cool. It is a battery powered device that is designed to coil a 50 foot microphone cable in under 10 seconds. All without kinking or binding.

kaltman_coiler.jpg

My first question is how does this device deal with the natural twist in a cable that comes from how the conductors inside the cable jacket are twisted. Both the conductors and the shield have a twist in them and this is why using the under and over style of cable coiling is so important for cable life. The natural twist in the cable is the reason that a good cable can be ruined so quickly if you wrap the coil around your arm instead of using proper coiling techniques.

It also appears from the short video at their site that it is necessary to have all your cables laid out in a manner where they are completely untangled in order to use the coiler properly. This could take a lot of stage space in a venue where you might have 30 or 4o mic cables, all mixed in with extension cords, speaker cables, video cable, etc.

Still, the idea of having a machine do all your cable coiling is intriguing. We are going to contact Kaltman in hopes of getting one to evaluate. I’ll let you know what we find out.

End of the holidays

Friday, January 5th, 2007

Tex Talks Well, New Year’s Day has come and gone, so its time to pack away the decorations for another year. Its always really tempting to just stuff them in plastic bags and pitch them into the garage, but I’ve come to realize that I will really regret that next December.

We’ve got some great products to help organize this stuff and it helps assure that next year won’t start out with having to unwind a tangled mess.

We’ve to Velcro One Wrap Straps on all our extension cords and by using these and taking a few extra minutes to coil them all up carefully, they are ready to use next holiday season. I use different colors for coding different lengths.

Nothing tangles worse than strings of mini lights (we use about 100 strands) so I secure these with nylon wire ties. A bag of 500 costs only $15.99 and that’s enough for several seasons.

Items like wreaths and garland are tied up with tie line and its great for bundling together items with lots of different parts. It has a soft texture, so it won’t damage or mar the surfaces of what you bundle with it.

Finally, when all the ornaments are stuffed into plastic bins, quick labeling with paper label tape and a Sharpie Marker means that I can quickly find what I need next year.

By the way, don’t forget to remove the batteries from any battery powered decorations. Duracell Procell batteries have a long shelf life and a good manufacturers warranty, but that warranty might not cover corrosion damage if there is a problem.

Time to get back to work.

How long will an extension cord last?

Friday, December 15th, 2006

Tex TalksI was finishing up my Christmas decorating last night and got to the end of my supply of extension cords before I finished the job. I had to dig deep into the cable archives and came across some power cable I had put together for a nightclub installation we had done 30 YEARS AGO!

Someone (probably not me) had taken the time and care to properly “under and over” coil these, tie them up with tie line and store them in a dark road case. I couldn’t believe what great shape they were in. I put them to use right away and didn’t burn the house down-at least not yet!

I thnk the two secrets to the longevity of these cables was that they were stored where no sun light would shine on them, thus no uv radiation to break down the jacket, and, more importantly, they were properly coiled. Any stranded wire (these were fine strands of copper) has a natural twist that needs to be respected when the cables are coiled. Coiling or wrapping them against this twist (e.g. wrapping them around your arm and hand) will quickly lead to permanent kinks and eventually cause enough of the individual strands to break down. Conductivity is reduced, heat is generated and, eventually the cable can get hot enough to melt the jacket.

Next time you have a new extension cord, take the time to coil it properly with an under/over looping method and it will last a long, long time.

Its Gotta Be Black

Wednesday, December 6th, 2006

Tex TalksA good portion of our live event production work involved providing amplification of live television events for audiences. It was exciting work and live television was a real challenge. I loved it.

We still occasionally do this sort of work and I had a recent ephiphany about something that had always bothered me these events.

No matter how “high end” the video production company we were working with, they would constantly string orange and yellow extension cords all over the event site. Everything else in their equipment package was always top quality, but all their power cables looked like they were pulled off the shelves at Home Depot. It was the sort of thing that you would never see in a theatrical or concert setting.

It finally dawned on me that these vidiots could only see what the camera saw. Any cable that was invisible to the lens (read-the director) was invisible to them. They really had no interest in what the live audience saw. Their audience was the television audience and if the cable couldn’t bee seen through the lens, these guys assumed that it was invisible.

One of reasons for starting buyextensioncords.com was because it was so difficult to find high quality, well made extension cords. We offer heavy gauge (12 GA) cables, medium gauge (14GA) cables and Electratrac MultiOutlet cables, all in black.

If you want to be sure that your power cables are all but invisible to the audience, then “its gotta be black“.

Got an observation to share with our readers? Pass it along.

Electratrac to the Rescue!

Wednesday, October 25th, 2006

mike2 I got an interesting call yesterday from a prospective customer with an extension cord problem. His company offers computer training courses all over the country by sending technicians to a local site and teaching the course in a hotel meeting room. The business is growing fast and they offer seminars all over the country.

One of the most complicated parts of this mobile classroom concept is actually setting up and wiring the computers so that every participant in the class has their own work station. He needed lots of outlets, even though his total power consumption was not all that high.
One of his classes was visited recently by the local fire marshall who threatened to shut the class down because the extension cord arrangement being used did not meet local codes.

He was inquiring about the potential suitability of the Electratrac MultiOutlet cable for this use. I could almost hear his sigh of relief when I assured him that these cables were exactly what he needed and that they would pass the fire marshall’s inspection regimen. They are UL approved, have high quality jackets and meet all codes for temporary wiring.
I suggested that the begin his setup with a 12 gauge cable. If he needs more outlets, he can reduce to a 14 gauge cable as he gets closer to the end of his outlet chain. That saves a little money and weight. Adding additional cables is clean and simple, because each Electratrac Cable has a handy outlet on its end.

If you try this, you will need to do some quick and simple math. Each computer, or other device, will show its power consumption on a tag on the back. You need to total this wattage and convert it to amps to make sure you don’t overload the circuit. Here’s a link to how to do the math.

Got a use for Electratrac Cables that might be of interest to our readers. Share it with us!

Making Your Own Multioutlet Cable

Tuesday, August 8th, 2006

spokesguyLet’s see if we can get back to the problem I was discussing in my Aug. 3 postings.I was lamenting not being able to meet a customers need for a better multioutlet cable because of the need to order in huge lots and to wait months for design and manufacturing processes to play out.

The customer had a real need and the solution to his problem would have given the world a better mouse trap, but, because the product, Electratrac multioutlet cables, was sourced in China, there was no practical way to get him what he needed.

Why not just build the product on a custom basis, using off-the-shelf parts? The unit cost, when factoring much more expensive US based labor, would be higher, but there would not be a large minimum order, there would be no complicated design and tooling costs, and the time line for getting the product into the users hands would be cut by months.

Here is my idea on making that better moustrap.

Neutrik now makes a line and panel mount connector, similar to their extremely popular Speakon connector system that that is intended for low to moderate amperage AC power distribution. It is called “Powercon” and it is a really well designed connector package.

Powercon is designed so that both the line mount and the panel mount connectors are insulated and shielded in a manner that insures that there are never any exposed electrical connections. It is safe, simple to use, and has a well made twist lock locking mechanism that keeps it secure. It would be great for a multioutlet cable design, based on this diagram.
Using this concept, it would be possible to essentially make up a cable of any number of outlet boxes, spaced at whatever interval you chose. You could have outlet boxes with single, dual or quad outlets and you could have multiple choices of cables to connect the boxes.

multioutlet

There are two problems that could be easily managed by someone with a little electrical savvy, but they could really cause a lot of trouble if used by someone who didn’t understand some basics regarding electrical power distribution.1. Since the voltage delivered by your cable drops over distance, you would need to take care not to extend your cable too far. Larger gauge cable allows more proper current (voltage) to be delivered over greater distances, but the larger the cable gauge the greater the weight-and the cost. As long as you were doing something like tent lighting, a reasonable voltage drop over distance would be acceptable, but if you were using the cable to power multiple electronic devices or computer work stations, voltage drop would really cause a lot of problems.

2. The second, and potentially much more important problem, would be the impact that overloading the cable (too many devices drawing too much current) would cause. It’s not hard to imagine a scenario where a fire danger was created or, in a really extreme case, the jacket of the cable actually melted.

It appears that the item that is missing from my design is some sort of inline circuit breaker that would see the entire load on the cable system, regardless of how many outlet boxes or lengths of intermediate able were used.

This would not solve the problem of voltage drop, but at least the safety issue would be addressed.

There are still a couple of more pretty good sized impediments to getting this better mousetrap to market. I’ll discuss them next time.
