@ Gadgetmall

Just tried to send you a PM but for some reason it doesn't seem to work today, I got "An Error Has Occurred!
Many apologies, but you can't view just any profile." 

Anyways, I made the mod as posted on the circuit board but no go   I went back and read your instructions but I'm not sure where I went wrong if anywhere, I tested the circuit before doing the mod and it charged up the cap likety split but after removing the cap the strobe jumping the diode replacing the 220 ohm resistor with a 10 k pot and soldering the 2 caps and jump wires all I get at the output is the same voltage as the battery!

Could you take a look back at the PCB pic I posted and see if there's an error on it please.

Edit: I'm posting the pic of the PCB mod, the kicker switch is only a wire which I touch to the 10 k pot if need for now.

Thanks,
Paul

Paul do not need HV mod . REMOVE THE PARTS INDICATED . MAKE SURE NO SHORT IN CIRCLE . and use 110 volt spiral bulb .This will not work as posted in previous post on 220 volt bulbs . At least Mine wont . > only other thing is the transistor might  needs replacing to a 2sd1960 . All My Fugi have that Transistor and all work however the fugi  as posted By Nieves's shows that there are a dozen different transistors on them so they are all not the same but some work some dont .OK hope that helps . DISCLAIMER :***** . USE AT YOUR OWN RISK ! . COULD MAKE YOU PULL YOUR HAIR OUT !*****

"Your Saying that open source is basically Useless"

No man, no!  Quite the contrary.  I am saying getting a patent is useless.  This, of course, is my opinion but I did go through all of this about 30 years ago. (at a cost of over $10,000)

If some lurker takes YOUR idea and design and manages to obtain a patent, it would be a very cheap simple matter for you to have it declared null and void...so...they will be out many thousands of dollars for nothing.  To obtain a patent, a person HAS to be the inventor, and the device can not have been made public.  You could easily prove that this was your design and it was exposed to the public (us) on such and such a date so...they would be totally out of luck.  Again, I am not an attorney and I do not give legal advice, but this is what my corporate attorney told me.  So, to reiterate, open source is the only way to go.

Great light photo!!  I love light.


@ MK1:

Look man, I am sorry for your situation but, do not be fooled, many on here are in similar shape in one way or another.  In fact if you bring in 600/month you made a lot more than I did last year....a lot more.  And I have to pay 300/month in child support!!!  (which is NOT tax deductible)  So, let's not compare situations because I have found no matter how bad things have been for me, I do not have to look very far to find someone worse than I am.  Things do turn around.  It has happened to me before and I believe it is happening once again.

I do believe we are all working together here.  Your design (with Jeanna) is doing much better than any of my toroid units to date.  We keep this up and there is no telling what we can do.

Also, if you think the "free market" got us to where we are today, well, this is just not correct.  We have not had a free market economy since Jimmy Carter.  If the government would let the market work, we would be just fine.  Again, just my opinion but based on hard facts.

Oh thanks for Clearing that up about if its public then they cant patent it .Great . No Worries Just a thought that these are real good Circuits .All of em . I personally Like The One Jeanna did with two 11 turns then a one turn secondary . that will run from a Dead(1.01volts ) for three and half weeks running 20 leds  . I Don't like to fuss  and i don't want to Shove Christian Values down an Atheist throat . It was wrong and i am deleting that post . .
Mk if you want to be evolved from monkeys thats fine 
Peace Guys . Lets Do something K ?
thanks Pirate

I am not sure i got what you said , but Darwin , i am not a fan.I am sorry i got this topic out of subject, All i am saying is that man is not human , The modern man live off the back of others, how human is that, keep poping pills , believe me i got to that point ,now out of it , i can tell you there has never been anything wrong with me. Except getting adjusted to society , human dose that , adjust to anything, the question is when its wrong morally , it destroy you , and nobody cares , but i do.

Take what you think i am saying and trash it , but all i want is a better future for all. The creator doesn't care much for people, that can't do it for them self.

Since people only see negative , and i am not about that at all, i did not even right anything negative.

making money , has replace the spiritual need , and guide our action , then what it left of life that is real.

The day you will die , what will you have to show for your trip , got to be a slave all your life , having only one thing in mind money, and making money , and more fun spending money.

We are one the same side, sorry you can't see that.

Yes we live in a tesla world , but we get only got stuff they could make money from. Why ?

Mark

Why do you guys get frustrated? I have no clue ? Did anyone even bother understanding , what i an saying?
Really ?

Hey When the the Lady's  gone the Boys get rowdy only thing i can figure . No i Know where your coming from . Its called Sin  and No one is Immune from it However  all we can do is the BEST  we can ..Hows the Song go . Teach your Children well ,their fathers Hell . and the Great one here Money is the root of all Evil . . your right but as you can see we ain't got none and they will take you away if you don't have any so lets not go there ok .

Thanks gadgetmall

I verified and there's no short where you indicated, I took out the HV enable jumper and still getting the same voltage as the battery at the output so it's got to be the transistor.

On the other hand I modified another Fuji board as posted by josepino but added a 5 K pot and 68 pf cap in parallel with the pot and no problems lighting a 45 watt spiral, the kicker is it's a 2SD2504 transistor like on the other 

Oh well thanks anyways, I'll try to find another transistor tomorrow.

BTW:  My bulbs are all 120 VAC from Canada

Paul

thats great .thats exactly where the 68 cap is on my mod . across the two legs of the Vr . I did not explain the Hv circuit because the output comes from a different spot . and as i said in previous post it draws more current thats why  i said don't use it . but if you do then the output is on the tiny transformer on top there is a trigger lead solder point . you can light other stuff from it .. and with one wire .  you tanked it .. same thing as what mine is doing  . Can you check the transistor . . if you pull it it will only read two ways out of six on the diode setting of the meter if its good . . I have not looked at his site . so i dont know what he did . anyways if your happy im happy .. Its a Mystry why it put out the battery voltage . My Eternal light is exactly as stated mod . It runs 11 hours . the other smaller cfl without the hvmod as i said runs 12.5 hours every time on the same battery i recharge . I got Some BIG BIG D CELL NI MH BATTERIES .they are very Heavy and put out 9000mah at 1.4 volts . HOT batteries .They will catch something on fire if they short out .. i am running the eternal light on that one and see how many days it will run .
