10 Great Snake-Oil Gadgets
The Byelorussian Strikes Again writes "Wired offers up 10 of the most awesome snake oil gadgets, from industrial cables sold as $200 ionized pain-relieving bracelets to a plastic chip that cures anything, improves gas mileage and cleans swimming pools.
One truly sad development: the infamous $500 wooden volume knob is no longer on sale."
multi thousand dollar EPFX machines that run off random number generators. Apparently this William Nelson fraud character lives in a multimillion dollar house in budapest because of it.
He believes this with all his heart.
So one day I had him do it over a stretch of ground we both knew to have some old pipes buried under it. And then I had him repeat it, blindfolded. He couldn't hit the same spot twice. Not even close. (The pipes were indeed buried roughly where he said they were when his eyes were open.)
I tried to explain to him that he was simply remembering where he had buried the pipes, and that it was his subconscious mind that was causing the wires to cross, but he really didn't want to hear that. He'd rather believe in dowsing.

When we had our main water line in Herefordshire replaced, Welsh Water had a great deal of trouble finding the original pipe valve in order to shut it off. Our house is an Edwardian Rectory about 500 metres off the road so after consulting the old maps of the area proceeded to dig a series of pits across our front field. This went on for a couple of weeks resulting in a fairly good recreation of a WWI battlefield.
It was pretty odd, we knew where the pipe entered the house and where the junction was to the mains, but the earlier Brits had a special way of routing things. Anyhow, believe it or not Welsh Water employ a dowser who looked like someone from the mesolithic; low and behold he found the pipe after a couple of days.
Pot luck? Maybe. Or perhaps Welsh Water have a strong desire to instill mystical beliefs in their customers. Either way that episode certainly changed my views on it.
I'm with you on Hi-Fi cables, but I do have a couple of "devil's advocate" observations.
1. One of my tech jobs involved wiring a TV station. I have never before or since seen any wiring scheme so complicated, or with so many genuinely mission-critical components. They long ago realized that it was more cost-effective in the long run to buy versus build for the wiring. So they paid top dollar for really well QC'd, precisely fitted wiring, with a very sophisticated numbering scheme. We are talking thousands of kilometers of cables here, hundreds of thousands of connections, millions of dollars of liability for downtime.
2. Some "hi-fi" wiring actually makes sense in the originally intended application. Take for instance, "directional" cables. I have a theory on this. Once, somebody saw patch cables that were intended for use in a production environment where the signal path was labeled. That is, in a situation where you have so many cables that are "To Reverb" or "From Preamp" that you actually benefit from having arrows visibly stamped on the wire. Folks who own big modular synths will back me up here. So somebody saw these cables and decided they could sell them to people who don't understand that the *wire itself* is not directional. Since pro studios use them they must be good, eh?
3. I love to see audiophile setups where the owner doesn't even bother to do a minimal amount of room treatment. No matter how good your sound system is, in a square room with a low flat ceiling and walls at 90 degrees to each other, you're going to have all kinds of reflections, phase interference, and standing waves. In a really good *room*, a clock radio can sound good.
4. Spend hundreds of dollars per foot on a cable that you need to be ruggedized, say, for the permanent install of the line array that you've built into a concert hall. Just because there are people who need this product (FOH engineers doing sound design for a concert hall, for example), doesn't mean you will benefit from the same tech in the home theatre setup in your house. And here's a hint: FOH line arrays aren't wired with any product from "Monster".

I wandered in to Radio Shack the other day for a TOSLINK cable. Young "not quite a geek" spys me and approaches. "How may I help you?" he says. "I need a few TOSLINK cables" says I.. and reach for the Radio Shack house brand.. "OH" he interrupts; "You don't want those; you want these" and reaches for a brand name that will remain nameless. I see a 59.00 dollar price tag on a 3 meter cable and look at the fellow. "So; what's the difference" I ask (Knowing he has not clue) "Well"; said the young not quite a geek; "these have better insulation". "Oh?" I counter; "Insulation from what; sunspots?" "No" he replies; "for all of the electronic gear around your house. The better insulation blocks hum and pops". Sad thing was the young lad had no idea why his argument was pointless. I remember the day when I could walk into a Radio Shank and hob-nod with my fellow wizards.. Now; I could probably go to 7-11 and get better advice. Rant mode off ..

A few years ago, I received many stock spams for "XLPI.PK", or Xcel Plus, which sells fuel and lubricant additives. Such additives are referred to in the automotive industry as "mouse milk"; they usually don't do much, and may make things worse. That whole category of products is mostly bogus.
Back then, their web site contained endorsements from the FAA and the US Army. The web site reproduced a a letter of endorsement appearing to be from an FAA representative. I thought this was a bit strange, so I sent off a note to the regional FAA office asking if it was legitimate.
A few weeks later, I got a call from an anti-terrorism investigator at NCIS. Someone at the FAA had looked at the letter and the web site. They apparently didn't like what they saw, and referred the matter for investigation of the use of unapproved lubricants in military equipment. That comes under the "sabotaging the war effort" laws, which brings in military investigators.
I'm not sure what happened thereafter, but the spamming stopped and "XLPI.PK" is now trading at $0.001.
True snake oil is completely useless. Monster Cable is good quality, well manufactured cable. For 1/3 to 1/2 of what they charge for it, it would actually be worth using in some situations.
never seen gold plated optical wires, but I did have to upgrade to nicely shielded optical wires, and they do serve an important purpose: it is more difficult for my cat to chew through the cable. My first optical cable did look pretty cool after my cat had worked on it for a week or so--little red lights peeking through along the whole length of the cord.
For example I once purchased a Rega RB300 pick up arm (for my turntable) from a retailer in a British Hi-Fi Magazine who also advertised large expensive speaker cables. Now I know because I have seen the results of tests on many of these cables in the old Electronic and Wireless World, that it is very difficult to differentiate between these cables using mere science.
The RB300 came of course with cables terminated with phono plugs. Now it happens that I use a moving magnet cartridge, and one of the characteristics of such cartridges is that they have a lot of inductance. This is usually compensated for by the capacitance of the cable between the cartridge and the amplifier. The cartridge which I used specified that it should be loaded with 200pF, a typical figure for a moving magnet.
Now being of the nerdy persuasion (no surprise, I'm posting on /.) I measured the capacitance of the connecting cables to find that they were 380pF and 630pF. The result of such a missload is unpredictable but theoretically could cause a large ripple through the frequency band.
When I contacted the retailer he was flabbergasted, he couldn't understand a word of what I was telling him. He kept asking "but does it sound right", to which I replied that as it wasn't correctly engineered I wouldn't fit it. He later phoned back again and got my wife, who though not technical herself, tried to explain to him that I had a meter with which I could measure capacitance. I eventually got the unit shipped back to Rega who replaced the cables, and then gave me an accurate measurement of new capacitance, which was in spec.
Interestingly not long after I noticed that there was an upgraded model for the pickup arm, and a little cottage industry which could upgrade your RB300 with better bearings and new cable
I never fitted the pickup though. My little adventure made me into a Hi-Fi luddite, and I instead rebuilt old an valve kit hi-fi system and an old turntable, so that I knew everything in the signal path.
