I MADE A IST MK2 60 VIDEO ... 


HOT! TRANSISTOR ...  LOL 

PRETTY KOOL WAVE FORMS .. http://www.youtube.com/watch?v=yk-hwnOmzn4

PEACE !

IST 

BTW BOY O BOY ....  COULD I SHARE A FEW THINGS...  APERNTLY IM 14 AND HAVE NEVER BEEN B4..  HUMMMMM  EVER HERD OF THE SUPERVISER... I HERE HE'S FAST!

IF YOU MAKE A PEACE SIGN WITH YOUR LEFT HAND THAT IS PEACE .. IF YOU MAKE ONE WITH YOUR RIGHT HAND THAT IS 2  SO NOW MAKE 1 OF EACH  PUT THEM TOGATHER  IM TOLD THAT IS 14.....     BTW WHAT YA GOT ...  GO TRY IT     

THATS RIGHT A W AND IM TOLD THATS 14

THEASE ARE RIDDLES IM SOLVEING ...  I GAVE MY CHILDREN THERE OWN STONE SETS NOW ... 

ALI DREW A NEW PICTURE FOR ME ...   SOME THING BOUT EYE NOSE EYE ... AND THE SUPERVISIOR ..  I ALREADY HAD 1 BUILT ...  I SHOWED HER AND SHE HAD TO DRAW ME A PIC TELL ME MY AGE AND EXPLAIN THE SUPERVISER TO ME

OH   I ALSO WAS TOLD TO CHECK OUT ROLLIAN SPIN ...      LOL  AND I ASKED HER BOUT THIS BUMP ...  ON MY LEFT HAND RIGHT IN THE MIDDLE I ASKED IS IT WHAT I THINK IT IS ...   NO ANSWER THEN SHE HELD IT TO HER BIRTH MARK ON HER NECK AND SAYS SAME ...

SO WILD TO SAY THE LEAST  ... 

I FELT I MUST SHARE THIS ..  BTW I NOW KNOW WHO SHE WAS IN HER PAST LIFE ...   A SINGER  THAT WAS CALLED SINGEEEE LOL AND HER NAME WAS THE SAME AS NOW ...  WHAT A UNIVERSE WE LIVE IN  .....   FUNNY THING WAS  HER MOTHER PICKED HER NAME AND WHO SHE WAS NAMED AFTER AND GUESS WHAT   SHE WAS ...

I bet you're right.
The right cap. I need to go to RS and pick up their mixed cap set. I always thought they were too small value, but for what I was doing yesterday the 100pF did the job. Next will be some supers. I have the slow super caps but I want to try some fast big caps, like 1 or 2 uF or mF or even F. Whatever it takes, I am going there.
How do you raise 30mV which fluctuates at 2.2Mhz to something useful. Something that will run gadgetmall's air conditioner?
A tank running off these fluctuations with inductors in stages, maybe.

hmm

But I digress,

What is the B+ in your drawing? Base with resistor attached?


@Gadgetmall,
Dig a hole 4' x 4' for a water tank and cover it.
Slip into it a roll of hose or main-waterline- tubing. Run the tubing from one side of the window through the water to the other side of the window. Blow a fan into a funnel so it forces the air in or maybe suck the air through. It will be very much cooled as it passes through the cold water in the tank and cool off your room for the cost of materials and running the fan.

Can you point me to any places better than/ or in addition to  Barrys coilgun site or crystal radio (which is sometimes off) to get instructions on how to use inductors and to match them with capacitors?

thanks,

jeanna

To be prefectly honest  I have not  given  Gadgits  airconditioner  much thought .
I figure   I will  work on getting MY airconditioner  going  and he  can  work on his   



I do have alot of  things I need to work on .......but   I have a plan







The  B+ in my  drawing   is   the positive  side of the battery .
If you look at the  clip  that  says B+  you  will see that the jaws are  open ......it is   " biting "  2 different  pins on the transforemr .   it is  in effect  the  pair of wires  that would be twisted toghether if this  was  a hand made coil .




So  far  I mostly   just   try  different  caps  and see what happens .
It does not take  long to see if  you are going in the right  direction .
The  big problem I have is not enough  sizes  of caps .

I did  take  an old monitor  apart  yesterday .   It had quite a few  caps ......some of them are 200V   a couple of them  1600V

Thank you @electricme !  I will try that or a 12v led I have available.

A 12 volt LED will not work.
The circuit is overheating because it is looking too much like a short circuit, to eliminate the heat, you have to reduce the current to the device, or put the 2n3055 on a much bigger heat sink.
In other words you are making the Tr work over its limits, over current or over voltage.

The 12v LED means it will work across a 12v supply, it may work in series also, but it will not work as you expect it to.
The whole circuit just might stop working.

The 12v bulb is the best, remember how a 12v globe was used in a dummy load at the back of a 27meg transceiver, everytime you pushed the leaver on the mic to test its output?

The 12v LED has a 1/8th watt resister in series with the K or A to reduce the current to it, it will light, the heat in the transistor will not appear, but the main output you are expecting, will not appear properly.

At one time I think you were interested in how to make the JT blink an LED. Here is a blinking JT circuit. It also will run for a very long time, about 1/2 year. Video attached.

Xee2:

What in that circuit makes the led blink exactly?  I just want to know for my own continuing education.  I purchased last year about 5 blinking leds from electronic goldmine and they work fine on a reg. JT circuit.  I wonder what the longevity of the factory blinking ones might be?  Probably not as long as your circuit because I am thinking, they must have put something in those factory blinking leds to make them blink, and it might waste energy?
