Very Informative Coil Core Type Demo

i compleated the 4" ALI COIL...

all done ..  works as i said it does ..

: )

i checked the voltage of the battery after 6 hours of playing with it and fully rechargeing the battery showen to 13vdc ..

and it was 1.28vdc in the battery ..

W

enjoy!

it charges quite quickly ..  it also discharges quite quickly lol  : )  it apears to work much like a super cap does ..  probally a good cap replacement  i may try a diode off it to a lead acid battery to use the cordless as a translator   and to give it a bit more push ...   altho this may change as the battery becomes conditioned to the high freq .. 

now...  lol   if i wanted to get sneekie wich it is possible sm did this ... lol

i could cram as many 3vdc button cells in there where the aa battery is .. and beef up the transistor .. and smack it with 30vdc ..  assumeing 10 fit in the space of 1 aa ..  the fly back from 30vdc would be large i would think this coil is putting out 68vdc wide open .. properly tuned to charge at high speed it is putting out 45 vdc .. this is the secondary wire  not the back load it runs bout 23vdc but that changes as the battery charge increases aswell if you put 24vdc to be recharged .. the cap voltage of the back load cap would be much higher ..   and if you loaded it enough on the secondary that the back load cap could fire a neon while chargeing the front end ..  you could also rectify off the overflow neon and feed back to source ..

just a thought !

if i upgraded to a HOT PATATO...  hummm  it might just scare ya!  hot p = cam flash unit ....  i call em hot patatos as the damm things  always bite ya ..  dosent matter how careful you are  ... with em there gonna have there way with ya ...  lol : ) so i have learned ...

i have charged LARGE value caps with them FAST!  like maybe 20 000 uf 400vdc caps ... DONT HIT THE RED BUTTON YOULL BLAST OFF!  i made videos but never posted them .. for good reason ...   if you hit the red button it will release all that at 1 time ...  not good for kids ...   

probally blow the flash right across the room ...  lol   anyhow with the cap that is on board it runs the neon A LONG TIME ......  and the output is like 400v there bouts ...  probally charge small caps ...   with out effecting the operation of the unit ..  if i used a big cap the thing would run a verry long time b4 i would have to pulse it agin for 3 seconds .. to top it up ... : )

wonderland...   dont get lost its a big park!

btw i used a 60watt light bulb to drain that big cap that was charged from the cam flash unit ...  the bulb WAS FULL BIRGHT ...  if i were to make a unit useing 4 cam units and 4 aa's i could light the bulb constant ... 

i know it ...

but thats kinda like cheating ...  lol

Nice work ist!

thanks bro !

you can do the same with a mosfet 1 coil and a freq genny ...

it IS MUCH MORE STABLE AS YOU LOCK THE FREQ THAT WAY... IRREGARDLESS OF THE VOLTAGE ..

; )

sure i have done this ...

ist : )

so a CAM UNIT OR A JT .. to charge the large value cap that the FET AND FREQ GENNY RUN OFF OF AS WELL IT BECOMES YOUR BANGER SOURCE..

the problem was at 1 time for me the flyback was frying fets ..  the GATE DONT LIKE IT! so for fets it is best to work with amps not so high a volts ... : )

if you have a coil the bangs out 600v and your fets are only rated 400v bang go the mosfets ...  now you can portect them ...  but to do so i think you need a p channel fet ..

i have used a coil and 1 fet on a 1"toroide  in the past ...  exactly the same as a jt  but single coil ...
and freq genny ..

: )

i have called it force feeding in the past !

I got a genny and a goldmine but no fets ;/ Subs?
