Harmonic Percolator
Sale Price: $225.00

The Harmonic Percolator is a distortion pedal that was made in Milwaukee Wisconsin in the 1970's. It used a silicon NPN transistor and a germanium PNP transistor in a design that passes even order harmonics while suppressing odd order harmonics. These even order harmonics are more pleasing to the ear than odd order harmonics.
This is the original circuit, not someone's interpretation of it. The left slider is the input gain or distortion control and the right one is the Balance control. The input is on the left and the output is to the right when looking down on it. This is opposite pedals of today but in its time this made sense. Left to Right - the same way you read.
This EXACT handmade duplicate of the original 1970's pedal employs the same obsolete number Germanium transistor and same number Silicon transistor. (Op Amps were never used in Percolators) The silicon transistor was potted in the originals to discourage people from reading the number on it!
Also used are the exact same number obsolete Germanium diodes. (They are NOT the common 1N34 or 1N60) Same type capacitors also are used. Mylar-Silver Mica, Tantalum, and Ceramic. The slider controls are the same as in the original. These New Old Stock parts have the original packing slip dated February 19, 1968!
Three original pedals were dismantled to help create this duplicate. One Percolator was totally dismantled, all its parts removed and measured. (Thanks John D. Greg K. Rusty B. @ Rockhaus Guitars and Jay T. for trusting your pedals to me!). I am sure it was unsettling for the one original Percolator owner to have his pedal dismantled, the transistor removed AND heated up to about 150 degrees to loosen the wax holding the metal ring obscuring the part number. There are no hidden parts, no mis-labeled components, nothing unusual beyond the circuit itself!

As a new kind of light source which is energy saving and long-life, the light emitting diode has long drawn great attention. After the large-scale utilization of the light in the 2008 Olympics, which achieved great effect, the light emitting diode industry has obtained substantial support and a lot of demonstration zones have been established. At the same time, an increasing number of enterprises have set foot in this field and some even say that the light emitting diode is on the top of the world. Is it a real prosperity of the industry?
There is no industry that has been put great hopes than the one of the light emitting diode, but this is shortage of customer basis due to its slow development. A dangerous signal appears: companies have put the cost reduction on the first place. They also have the lighting current increased with the luminosity keeps steady, thus the number of wick will be reduced and the cost is able to saved. It is not good for the whole lighting industry.
There are some disadvantages for this kind of lighting. As is well known, the heat endurance of the light emitting diode is not very good and the current heat dissipation design does not meet the requirement in such a strict and high requiring field. As a result, a perfect method for both the heat dissipation and the weight has not been promoted yet. Then is the problem of its life-span. The wick life-span in the light reduces as temperature rises and half of life-span will be lost at the condition of the rise of electrolytic capacitor temperature.
By only replacing and imitating, the current light emitting diode market will not have space to develop. Some outstanding products must be invented and companies producing the product must be have the knowledge of the combination with the customer and the features of the light. That is the point that people pay little attention to. Related chip of the light emitting diode is: M54583P.

Evolution of Dpss Lasers From Gas Lasers
Since early developments in the 1960's, lasers have gone through a number of transformations using different types of technology. The previous generation of lasers were bulky and fragile gas lasers such as ion lasers. The current generation of lasers are diode pumped solid state lasers or DPSS for short.
Diode-pumped solid-state (DPSS) lasers are solid-state lasers made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode.
The most common DPSS laser in use is the 532 nm wavelength green laser pointer The green light from the green laser pointer is generated by a process called frequency doubling. The beam typically originates as a 808nm beam from an infrared A1GaAs laser diode. This beam then pumps a crystal made of neodymium-doped vanadate or Nd:YAG to produce a deeper infrared beam with a wavelength of 1064nm.
The last part of the process is passing the 1064nm beam into a KTP (potassium titanyl phosphate) crystal which acts as a frequency doubler and halves the wavelength of the beam to green 532nm laser beam.
The Viper laser pointer, the Hulk portable laser and the other lasers from Dragonlasers are DPSS lasers and use the same principle of pumping a crystal with a laser diode to produce a laser beam.
Advantages of DPSS lasers
DPSS lasers have a number of important over the older gas lasers
They are solid state with no fragile gas filled tube which requires the gas pressure to be maintained correctly for optimal performance.
· Durability: DPSS lasers are more rugged than the typical gas lasers that use a gas filled tube with precise pressure requirements.
· Resonators: DPSS lasers not require the complex resonator structures found in gas lasers.
· Optics: The optics in DPSS lasers are much smaller than the optics in gas lasers. This allows the optics of DPSS lasers to be adjusted in the factory, an adjustment that will normally last the life of the laser. The optics in gas lasers on the other hand need adjustment prior to each use.
· Size: DPSS lasers are much more compact that gas lasers.
· Efficiency: A typical gas laser will output about 2-3% of its electrical input as light. The other 97-98% electrical input will be lost as heat. One reason why gas lasers typically need water cooling. DPSS lasers are much more efficient and output 25-30% of their electrical input as light.

Is there a LED DIODE Pen that emits light in a sharp focussed nib?
point in red green and violet colors on plain paper . There is another paper with the same pen in another place. When the light points in place A move in the defined rectangular base shape the pen moves in the other place (automatic writing) highlighting those same exact points with the opposite color coordinate when viewed through a special eye screen it displays the original "point movement map" made in paper A "the hand that moved the pen in the mapped points" "the hand that rocks the cradle is the hand that twists the ladle"
Uhhhhh........ Yeah, sure. Why don't you go research that on the Web? Especially that last part.

Amazing Laser Application 4: Optical Data Storage! [Uncertain Principles]
What's the application? CD and DVD players use lasers to read (and in some cases write) digital information from convenient plastic disks. What problem(s) is it the solution to? 1) "How do we store a large amount of digital information in a convenient and stable fashion?" 2) "How do we make everybody buy the White Album a second time?" How does it work? The optics at the core of a CD player are ...
