monster yet efficient and simple joule thief

Step 3 Putting it all together

Now take the bread board and put the parts as shown in the pic.put 10uf cap as shown in the first pic and the 22 nf cap as shown in the second pic.put higher rating resistor for lower power and more battery life.before puting it all together search the google for its pinout.example:tip 3055 datasheet.if u r lookin for 3055 pinout

Another Circuit Shams stolen off the internet, this time it was taken from Colins site www.TalkingElectronics.com in Australia. You are just a thieving pretender Shams, you take other peoples hard work, and pass it off as your own, but this time ive emailed instructables, and ive sent an email to colin as well, with a link to this project so he can see how his hard work has been stolen....you dont even have the manners to acknowledge the work that you steal, is someone elses, you just pretend its your own

[shams]

and...look i ve given the address on my first page of talking electronic and where i get it from..........this is instructables.com bro...here people write instructions step by step how the have made something.....so this instructable is as others.....

[shams]

nope ...look there are all the links and address on the shematics...so i didnt stole it.....and whats ur prolem really ??....why are you after me ??...cant you oil ur own machine ??

[jomac_uk]

YES...you did steal it, it clearly says on the cappels site, that everything is copyright (c) It ALSO says that you CANT use any material WITHOUT the owners consent!!

You just cut and pasted someone elses work WITHOUT their permission, and YES it is THEFT

Why are we after you, as you put it? because you are a THIEF of other peoples work, probably incapable of designing your own!!...and yes there are a few of us now that will be following your future work to make sure its not been stolen from someone else!!!

[shams]

go ahead man....do what you do...say what you say.....i have no headache for you.........

I hope that in the future, Instructables shows the courtesy of asking copyright holders for permission to use copied material.

The web page on my site that sorts out a lot of the details and contain tips to debug the circuit:

Lotta confusion here. Two different schematics, 3055 is not used here. The second schematic shows a 10n capacitor, but I've tried this circuit and it works without the cap, but goes dim when I add the cap. I recommend not to use it.

[shams]

just replace 2n4401 with 3055........my one doesnt go dim.How many turns have u used ? and whats the size of your core ?

[acmefixer]

The number of turns I use depends on the core material.  I try to keep the inductance of each winding at least 100 microhenrys.  Some cores are low mu (permeability) and need at least 20 to 30 turns.  Some high mu cores only need 5 to 8 turns.  See my blog here for some of the cores I use.  And here is a higher power supercharged JT I built last week using some new stuff I bought.

Keep the resistance of the toroid windings low.  Your JT will lose brightness if it is too high.    If you can measure it with a cheap DMM, a half ohm for instance, then it is too much.  Heavier wire helps, too.  You can wind the core with a second or third primary winding and connect the two or three windings in parallel.

As for substituting the 2N3055 for the 2N4401, you will have to do more than that.  The 2N4401 has a gain of several hundred, the 2N3055 is lucky to have a gain of 100.  If you leave the resistor at 1000 ohms, then the 2N3055 will conduct less than a third of the current of the 2N4401.  You have to allow more base bias current by lowering the resistor to 330 ohms or maybe less.

Have fun.  Best of success in building your Joule Thief.
