| Tesla: electrical discharge in a globe with rarefied gas without direct
contact |
My wife says the age is not synonym about wisdom, also claims who
"plays" with these devices, he must necessarily to be a little crazy:
maybe she is right; I advise to give a look to theWebRing hub
HT site or WebRing hub tesla
or to the Italian site: http://S.webring.com/hub?ring=italianteslacoil
to see how many "crazys" there are in the web ... it is really
worth.
 |
Tesla coil built by me more than 35 years ago. |
 |
Spectacular high tension sparks and high frequency -
about 80.000 Volt |
 |
Van De Graaff, electrostatic engine I have built
recently. |
|
 |
The neon lamp lights up without electric contact. |
 |
This power is not dangereus, only a light pinch. |
 |
One does not joke, here the "lightnings"
exceed 50 cm: about 7-800.000 Volt. |
|
 |
The Tesla Coil, in:12 '000 volts, 30 ma. Out
about 500.000 volts |
 |
New Tesla, tubes version. |
 |
New Van De Graaff in building |

Here what now remains of that magnificent tube: the
weighing anticathode. |
 |

Telescope I have built gathering a cathadioptric
Russian objective: 1000/10 , spyglass prisms and microscope
eyepieces. The pointer is a aim for hunt rifles. It works very well
and easy to transport
