Second Stage Joule Thief Circuits

i use the neons in all my test once i get it to something that i like i will switch the scr or triac and neons for a sidac
if you build this circuit don't forget to have a load on the scr circuit before you cut it on
if not you will blow a cap.. i know a 250vdc poly cap will hold over 1200 volts before it starts smoking..lol
and they stink...
in the video below it shows 29.** ma's that is what charges my cap the fastest
if you don't mind going to like 12-15 hz output you can go way lower on the battery draw

This is perfect robby  . the amp draw is very close to a nornal evilmadscientist JT of 20 ma . Fantastic Discovery on two toroids . I wonder if they are stacked will that be the same . Should be and maybe got more induction ?  Thansk for sharing this awsome cap charger!

i not sure how well it will work seems like i tried it
i'll be probably moving to a smaller toroid soon like the 1'' in the same fashion
just to reduce size
or maybe even a e-core

hey
i was thinking of going back to my first design which was ac.. i just never had the right ac caps to it
right now with a good steady hz a 120v 4w bulb the filament will burn bright red but won't light
so i thinking maybe i losing something in the bridges...
the real reason i posting here is that i was going to tell you guys that with this circuit pulled 105ma's i nearly had it to self run... feeding back off the second stage with 2 turns on a toroid thru a bridge to a run cap would run it for 30-35 seconds after the batt was unhooked
so i was thinking maybe since i got the ma's pull down to 30ma's maybe it will run on its on this time...
ah dreams...lol

hey do you think this place has good cheap meters or don't buy them???

harbourfreight . 2.99 for a multimeter LCD 2000volt scale backlit . I bought a bunch last christmas . they are great ! I have one a few miles from us . look em up on the internet harborfreight tools . they got some neat stuff.the meters are red and have two types . if you rneed to calibrate them there is a pot inside to adjust the volts to match your other meter . once set its accurate !

Self run it a reality . Get ready !! and you are right if you can get the input down and harvest that Hv In a BCap your self running , I know my circuit will . there are Doubters but they havent build it    Alex will . its so simple it crazy simple.
