Joule Thief

hi all,
i had a go at  @hazens1 design today. i could only
fit about 190 turns on a unknown dark green toroid.
this would not light a 4Watt fluro until i connected the
end of the pickup to the base, the start to one end
of the fluro, and the other end of the fluro to the
negative rail, this is how the capacitor is connected
in the fugi circuit.
i'v modified @hazens1 diagram to show this, the
diode isn't needed, this is the diode @gadgetmall
shorts in the fuji circuit. now my fluro lights without
the need of touching the tube as i've needed to do in previous experiments.
just thought this may help someone.

the lines at the bottom of the pic show how i wound
the toroid, just felt like doing something different.

Wilby:

I was also thinking that.  Basically what I have been doing is going back and recreating all of my Fuji experiments only using the EB instead of the AA battery.  So.....the 200 leds, 300 and yes....400 are on my list.  I am probably going to hit the wall soon with these two 10 farad caps.  Once work picks up again, hopefully, I can get that 3,000 F cap and then....look out.  Thanks for watching it and also for the rating.

@ mikem_2au

Thanks for the circuit mods. I will try this and see if it eliminates the need to touch my tube.

EDIT: Are you sure you have pickup coil connected to base? I though it was connected to collector coil in Fuji circuit.

@Bill,
I went and took a looksee at your latest Utube video showing the 48" fluro being lit up.
That is excellent, I couldnt access the leave a message as Im not on my regular PC, ha ha.
5 stars mate.

Just an idea I have for you, leave several batteries on charge via the earth battery, all day long then connect them up to run the fluro at night. Someone here suggested you/ we use a LDR to switch on a transistor at sunset, it WILL work.

Australian slang strine
@[Arvo] [Bluey], (you will no who you are)

[G'day] [mate], is the way to say it,  said like (Gu'd - day) At sunup, I got rid of the [Bush oyster] lol.
Isn't this Jule Thief a [bottler].
Some people think the JT isnt their [Bowl of rice], but it's [Beaut].

I gotta go to [Brisvegas] next week for a fello [Cain toad], so I'll pick up some bits for the JT if I don't [cark it] on the way. I might [Chuck a sickie] to do this.

I will keep the [Mintz plates] open on the [Frog and toad] on the way.

I see you were mad as a [cut snake], you were really [Spewin] before, never mind, just sit down with a [dogs eye] and calm down a bit, but look out for the [Dunny budgies], [Fair dinkum], I think you are [flatout like a lizard drinkin] with all the research you do, I'm off to see some [Aerial pingpong] with a [Sanger] later on tonight.
Wish it was the [Bush telly] instead, boiling the [Billy] and munching on a [Bikkie].

Tomorra, this [Banana bender] must get a [Scratcy], and if [She'll be right], I'll [Skite] and [Shout] you all if I win.

Now I gotta take a [Squizz] at Bill's video and [veg out], then I will see if anyone is trying to [White ant] my [Yakka] on the JT.

I'm [grinning like a shot fox].

OK Jeanna, and others, here is a web site to cut your teeth on ausie slang.

@xee2, yes, the pickup is connected to the base.
( the end not the start of the winding)
i have sacrificed 2 Fuji transformers to find out what
went where, so i could try and replicate with a toroid.
I will try and post same pics of what i found soon.
