forwardbias -> Violet Wands and Electricty... Greed (2/25/2009 5:08:15 AM)

I am curious about Violet Wands, not for actual S/M play. But where you can get a vintage device. I am very into the electrical reserach of Nikola Tesla, which his air core resonant transformer (Tesla Coil) Really made things like Radio and Television communications possible, they are also fun hobby projects for making stuff spark, ion engines, and was used in his proposal for gas discharge lights that required no wires. I have plans as well as a link to a site that sells a SSTC. Teslas coil was spark gap pulsed in 1891 when it was invented, solid state coils have the same effect, but dont generate all the EMF noise as a Spark Gap coil, also the spark gap needs cleaned and the contacts need replaced over time. I have seen videos of a vintage violet wand device, makes about 6-12" streamers, the tubes glow purple, at that range I am guessing about 100-250KV, but low current (micro amps). Anyone know what a vintage set would run for? Or a working replica of a device? I am amused by early AC electrical engineering, and DC as well. The box had a light on it, and a rotery switch to adjust I am guessing current into the primary transformer, it was copper bars on a semi circle, an arm on top would let you adjust current. I forget what sort of theropy is was used for, something with joints in the knees or something though, a similar treatment is used today, just using much more advanced electronics, discs are places over the knee, and a modern digital box on a cart delivers the voltage.
Dont get me started on the Titanics electrical system, the DC plant on Titanic was bigger and more advanced than any power plant in a city. 1.6MW of power, 100 volts at 16,000 Amps, 4 dynamos each rated at 400KW. The 1.6MW was then fed through a feeder switchboard of 28 breakers, those were divided into smaller breakers like what you would find in your house. There were no self regulationg diodes or transistors then, as the load changed, DC is load dependant, operators in the electric plant would adjust the RPM's of the dynamos, which ran off steam, if more power was needed as voltages dropped under 100V, they raised steam pressure, as load eased and voltages went above 100V, they lowered the steam, this was done by levers on 4 master breakers, each had 8 control levers to adjust the speed of the Dynamos, the levers adjusted gears to run at lower or higher RPM's depending on the load requirements at the time.
Interesting how they did stuff back then before computers, voltage regulators and solid state stuff was invented. Vaccuum tubes did exist, such as on Titanics wireless in the detector circuit, they were very simple at the time, and no sort of automatic switching circuits existed at the time except for electro-mechanical logic gates, which Tesla used in an 1897 invention of the first radio control device. 100 years ago, they could do alot electronics wise without solid state components.
Some of his experiments were quite amazing, in one experiment, he pumped 10 million volts into the earth at resonance, when the current came back, it made 130 foot lightning bolts that could be heard from 22 miles away. The power was greatly amplified, however his experiment for free enegy was too much for the Colorado Springs power plant, the generator burst into flames due to a massive overload from the excess power. The earth resonates at around 6Hz, by the way, resonance is when waves match or harmonics match, things are still not fully explained as to how a Tesla Coil can make so much voltage gain, some think its something with Zero Point Energy. What is known is that the Capacitive and Inductive reactance, when they match in a TC, rather than canceling out, makes for a huge gain in voltage. This theory of resonance is how radio and television were invented. Tesla actually invented radio, his coil and spark gap design, and in an experiment, claimed to pick up signals from space from intellegent life, this was later disproved, odds are, he picked up signals from Earths electromagnettic fields, the Sun or Jupiters radiation belts. That dont matter where the signals came from though, as he ecentially made the radio, before Macoroni did, Macoroni actually used Teslas coil design and spark gap in the Macoroni Wireless. Tesla also did research into RADAR research, though he did not make a working device, at least thats what "Big Brother" claims, he made plans on paper that later led to Radar 50 years later. Tesla also did work on a Death Ray, using his large resonance tower, in 1908 he fired it over the Arctic, letting an expidition that would be out there at the time if they noticed anything. The ray made a very dim beam, afterwards a mysterious explosion happened over Tungusta with a force of 15MT of TNT. No meteorite fragments were found, and its still a mystery how 700+ square miles of forest was flattened in an instant.
Makes you wonder if Tesla really made the sort of Death Ray depicted in those 1950's sci fi movies, zap! nothing left of what got vaporised.
Anyways, sorry for the long thread. Who out there likes to play with electricity, but not in an S/M sence (Mad scientists, hobbiests, tinkerers, etc) I should admit that I also like to play with fire and burning lasers, guess I just like danger lol
