Annular Solar Eclipse of the Sun 2012 May 20-21

Solar eclipse of May 20, 2012

Update: We couldn't see the Annular Solar Eclipse of the Sun 2012 May 20-21, here in Azle TX, because of the Clouds. But, I watched a Live Feed Online. It was actually fun to watch it that way. It was a Feed done by Scottys Sky. He had a live Audio - Video Feed going the whole time. He was in a Gas Station Parking lot. And he drew a crowd. He let people look through his Telescopes and gave out glasses to people, for free. So, that they cold look directly at the Eclipse. It was almost like being there:) He said in his last Web Cast. That he will Probably Not be doing the Venus Transit 2012. Because he has to be a Work. But, I checked his Page today and there he was Live and Online!:) I later heard him say, that he was actually in the Parking Lot, at his Job. And he was just letting his Telescope run on Auto Tracking, while he works. That accounts for the Web Cast being silent, most of the time. He does these Live Sky Web Cast's when he can. Check out his UStream Page and see his past Videos here too...

The joint JAXA/NASA Hinode mission will observe the eclipse and provide images and movies that will be available on the NASA website at http://www.nasa.gov/sunearth. Due to Hinode’s orbit around the Earth, Hinode will actually observe 4 separate partial eclipses." Scientists often use an eclipse to help calibrate the instruments on the telescope by focusing in on the edge of the moon as it crosses the sun and measuring how sharp it appears in the images. An added bonus: Hinode's X-ray Telescope will be able to provide images of the peaks and valleys of the lunar surface.

Viewing the Solar Eclipse through a Welding Helmet...




Image From.... http://weilerwelding.com/shopsite_sc/store/html/helmets.html
 
Excerpt... 
Getting back to that 1994 eclipse in St. Louis, there were several people holding a #14 welder's glass to look at the sun including myself. Do not buy # 13, #12 or smaller... they will not work and you CAN damage your eyes! You have to have a #14 welder's glass to see this celestial event. Several people showed-up wearing their welder's helmet to look at the sun. If you are in a large gathering, and you want the press and everyone else to notice you, then come wearing a welder's helmet! And another thing I should mention, don't use hospital x-rays for they will not work. I have seen people do this, and again, you run the risk of damaging your eyes.

Never view the sun with the naked eye or with any optical device, such as binoculars or a telescope!
This is more than advice. Why? As a kid, did you ever take a magnifying glass out into the sun and burn leaves? If so, you probably remember that when the focused sunlight coming through the lens was refracted and concentrated to a small spot, the energy available there was truly remarkable. Guess what? You have a lens just like that in your eye. If you look at the sun, your eye-lens will concentrate the sun's light and focus it to a very small spot on the back of your retina. This can cause permanent eye damage or blindness. Additionally, there are no pain sensors back there so you won't even know it's happening! Have I scared the willies out of you? Good!


There are safe ways to view the sun. The simplest requires only a long box (at least 6 feet long), a piece of aluminum foil, a pin, and a sheet of white paper.

Saros 128 (58 of 73)
Catalog # (SE5000) 9535
An annular solar eclipse will take place on May 20, 2012 (May 21, 2012 for local time in Eastern Hemisphere), with a magnitude of 0.9439. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun, causing the Sun to look like an annulus (ring), blocking most of the Sun's light. An annular eclipse appears as a partial eclipse over a region thousands of kilometres wide.

Contents

Visibility

The annular phase will be visible from the Chinese coast, northern Taiwan, the south of Japan, and the western part of the United States. Guangzhou, Taipei, Tokyo and Albuquerque will be on the central path. Its maximum will occur in part of the North Pacific, south of the Aleutian islands for 5 min and 46.3 s, and finish in the western United States.

North America

It will be the first central eclipse of the 21st century in the continental USA, and also the first annular eclipse there since the solar eclipse of May 10, 1994 which was also the previous eclipse of this series Solar Saros 128.

Great Audio Projects - Efx Processors and such, that were made by Peter over at, Hilltree Productions

Here are some really well made and good looking Audio Projects - Efx Processors and such, that were made by Peter over at, Hilltree Productions. I really like his work! Both the electronics and the craftsmanship too:) I've Posted some of my favorite projects here. Make sure and see the rest on his Projects Page, Hilltree Productions.

The plasmadisk synth controller

More information.

At this place i discribe one of my neon projects,… sound generation by high voltage and discharges. This is my plasma disk synth controller.
With this controller , i can controll a synthesizer or a filter  [filter or osc with control input], or for generating oscillator sounds such as my  hexillator. On the anode in the middle of the disc, there is a very high voltage . Therefore it must be carfully mesured, to prevent damages to my multimeters . Without touching the glass, the plate generates a fieldpower voltage of 10 up to 50 volts of alternate current power. See the lightning red  leds  of the duspol [it is nothing to connected.] when i put one contact of the meter to ground and the positiv of the meter connect to my hand, and with my other hand/finger plasma touches disk. .the multimeter displays 50 volts and up to 200 volts alternate current power. The voltage of  the lower part  of the disk varies from  50 volts to the upper part of the disk 200 volts. The high voltages are have no high Ampers so it is not really dangerous, but after all , there are many posibillities to use this disk in a nice diy project.

Maybe must i put a piece of metal or a piece of aluminum  tape on the edge of the disk and connect this to the ground/ground for more effect. Whith only the fingers on the plate will not generate enough voltage to controll another piece of gear.. I  think that I make it nevertheless an universal controller. With a standard voltage of 0~10 volts or 0~15 volts. To use the plasmadisk as a generator ,it is nevertheless a bit dangerous. There are still thousands off volts on that anode .

The steampunk doomsday machine.

This is my diy project  "steampunk doomsday machine". it is a fuzz /compressor like external effect for guitar or synthesizer/drummaschine .But i made it with decent steampunk influences  . So with a lot of wood and brass/ copper .At the top you see two 230 volts DC driven lightbulbs . [very dangerous]. Through the burning lightbulbs i send a audio signal . [this trick was contructed with transformers] The 2 brass tubes at the top sides are fatt condensers /elco.  And the 2 brass plumbing tubes hold a couple of ldr for the optical compressor.The switches and potentiometers are input/balance, compressor, thru bypass,sence/impedancy,gain/output. I discribe no schematics here on this project, because the whole thing is lethal.

Easy and simple pre-amp/booster

More information.

Last weekend i messed around with a reverb tank.
And the large disadvantage of these things is, which they are in fact entirely passive, and therefore for/after amplifying is necessary to work.
I had already searched in books and the Internet for a simple universal schematic.
In the books stand frequently solicit of that basis with general values which you yourself must count the Internet from, and not this way beautiful universally and minimalistic such as I have made this diy project.
Therefore. .what I here now mail does not exist in fact already, however. . also this way beautiful completely. [it is basis electronics]

Nicely universal pre-amp/ booster therefore. Simply put it ,for or after, a piece of gear.
Also nice as a stompbox fx for a [bass]guitar .For amplifying of reverb tank or ring modulator… your own imagination is the limit.
Or simply for an power amplifier .sounds well clean.
The price of the whole diy project is proximally not more than 3 euro.

The upper diagram is the final, therefore good version.
The bottom diagram works also good, but is more if basis/example version has thought with gain regulation these capacitances also no [100k] parallel concerning the entrance and termination for possible condensers at discharge [pop noise]… volume must regulate on the piece gear.
The npn transistor are again not critical, you can use any type.
I have try standard npn silicon bc547 and this sounds good with it.
Amplifies 4x up to 10x.
Also germanium types  can be used for a smattering luxuriously and vintage sound.

smashotronics™ compressor/Limiter

More information.

This is a minimalistic compressor/limiter that I have developed. This thing works on line audio level, and is purely for creatively use , not special for in the studio .Place it  behind a synthesizer or a sound source. Now I am again reasonable successful in creating The smashotronics™ compressor/limiter.

It is even for electronics beginners  cheap and easy to make .Easily to build in plastic/metal case or bend synth project .But the whole thing works with 1 active element, as it happens, normal npn transistor. For the transistor what can be used [such as bc547] If you want this project somewhat luxuriated ? ,use a germanium type transistor . The diode’s d2 and d3 are the passive limiter part.
For more limiting ,put some diodes in serial with d2 and d3.The complete diagram is not terrible critically, and any component can chance with another type. .One side of potentiometer R8 is possible with 1 leg for the condenser C1 [is now after] for real true-bypass a regulation. The whole thing works with 9V~12V dc voltage.

Steampunk "Equinoxe Device"

This is a steampunk project with wood and brass, based on the 70" electro harmonix small stone phaser. With decent steampunk influences , not overloaded with brass gear and wires that doesn’t work !!!. The small stone phaser was a broken second hand pcb  with no case . Repaired and modded. And ofcource …everything works fine now. On the top of the case there is a on /off pulse switch [with my normal relay to puls relay circuit] for the thru bypass and a status led.Inside the device there ar six potentiometers and a toggle switch and 2 color led. Controls from top left , Dawn, Cloud, Hue, Wave, Axial, Fog, Sun, Moon, Eclipse. Bending and mods from the original pcb are a wet/dry control , feedback/resonance , depth of the effect, speed , gain, and the Q from the filter.

Tube pre-amp / Filter

Here I describe my tube amp/filter project.
I was a complete time busy with making/devise of tube filter which works on line level.
 Simple behind a synthesizer or audio sound source.I searched for a standard tube design [it exist already more than 100 years] that work on normal stompboxl low voltage of 9 up to 12 volts DC.Also had there and rather cheap, and easily available tube is used.
That became ECC82 [12AU7].But because fail technique already very old is, and much have been invented already and made, stands in fact therefore everything already described.Also is stuck you with many components to let work to the tube.What information concerning Ecc82, the beginning 1960s.Rather basis work therefore, and such documentation is described frequently already standard from the factory.

Now I met again that this design concerning am taken by Matsumi in its valvecaster called.
Also is there already quite what documentation about this to find on the Internet.
[For people who want know this, the design is therefore free of rights]
The tube can be used therefore of nicely, almost highend, hifi clean [components adapted with what], to reasonable overdrive.

Now the Ecc82 beside the many called advantages also couples has disadvantages.
This tube not to see you glowing, because the filament is hidden, this are beautiful solve behringer style If the tube on noval fsocket stands you can place in the middle of small ledje which the tube lighted.Also this tube is send very difficult in itself oscillation.
And if you have him in itself oscillation you no longer hear original audio indicator or grasp the complete circuit dead.

I this by my own DIY filter have solved design [that an active derivative is the baxandall tone regulation], minimum in the diagram to incorporate.This goes really as schakelbare [or one can omit it whole for audio/tube purists]Whole is for which what is not electronica make knowledge difficult.
