Hi, here gathered at leisure small, self-joule thief
http://www.youtube.com/watch?v=Rm3LPMQ-xdU
Hi zhak,

What do you mean self?

When I make a jt circuit that blinks like that one, I am NOT satisfied.
It COULD be made to build on itself and blink faster, but I did not see that happen on that video
Is that your video?
If it is yours, please increase the resistance of the base resistor to make the blink faster.


@observer,
Are you really recharging a battery from your pill bottle?
How long does this take?
And I am not sure why you are doing this when you can run a jtc directly?
I suppose the cd player needs faster amps than the pill bottle can deliver. Is that it?

thank you,

jeanna

Da

I think it's a Regular Old Stainless Steel Bolt... Cheapest Bolt you can get at ACE.

Jeanna,

I have not tried charging a NiMh with the pill jars yet...
     At this point it is next to a forgone conclusion that will work.
           The Pill Jars give off Amps and Volts just like any other power supply.
                   The more Pennies the more Amps... (voltage stays the same)

I am curious how long they will last.
I am wondering since there is no acid.. that the metals will not disintegrate or disintegrate very slowly..
Which would mean, with fresh water every now and again, the things would run virtually forever.

I also left out the possibility of a 2nd Joule Thief connected to the Jars that then Recharges the Batteries in my diagram.

The Reason to put in a couple rechargables is that the pill jars will give off energy 24/7...
               The stored energy can be used for the few hours a Lamp is actually used.
                    Smaller Pill Jars will thus be able to run the Lamp.

The Idea is that any item that is used intermittently (and possibly requires alot of Amps)
                                                            would use less "Pill Jar Volume" if the energy is stored during none use hours.

I think you kinda figured that.

Yes jeanna is my video, I'll obey your advice to increase the resistance. Long working device paired with a super capacitor at 1F, almost a day

WOW almost one day, on one touch of the battery to capacitor? wow.

This is what I find so very interesting about the joule thief.
I seems to be able to re-use some of the energy that gets into the system, and unless we push the limits on how little it can use (as you did) we will not suspect it is coming around again.
xee2 always insisted on using a capacitor across the battery leads, and I am beginning to always put one there too.
A 1F super cap is even better.

About my suggestion, if you are providing less mA than the joule thief can use, then increasing the resistance will not help to stop the flashing, but even then, you might get a steady-on light with a bigger cap, although you might have to wait for it to get started a little longer.

Since it was your video and I did not understand what you were saying,  ;) I will ask you about the way you reversed the battery to the capacitor leads.
Was that just because they were reversed the first time?
or
is that a trick to get this to last longer?

Thank you,

jeanna

You speak about the super condenser (ионистр)?, 1F it prolongs a life for days.
jeanna
I have not understood your text a little!?
You want the scheme?

hi jenna i just read someware that you have a 24 led medside light and that it had been runniung for one month and was expecting it to last about 6 month

this sounds amazing could you explain how exactly you managed this pls
the one i have should manage 100 hours acording to power draw etc real world i seem to get 10 hours maybe my batterys ant fully charged or holding charge like they should but a month is just wow

i just got to page 1233 and wow ist finerly did something right now if this dose work then he may of done it (dont belive i said that withh all truth he needs a stray jacket and a padded cell but thats a diff story)

if the video head pulse motor can be replicated i belive it can be easy done i will try my sefl when i find the parts needed

now from what i worked out
one coil works as a dynimo putting vac a bridge then turns this into vdc into a cap ready for the reed switch to send power to the electromagnet to send the pulse needed to repel the roter(fly wheel)

now may take a bit of tuning and wheel a few coil winds to figure this out but wow it could work

now what if we adderd a 3rd coil to charge a battery etc
now this with jennas jaw dropping lamp from a jt i belive lighting a house has been solved

let me know if any one else can see if or can attempt it

Greetings,

Update on the Penny Pill Jar JT which has been running strong for 8 or so days.

               1.  I put a (100uf) across the Batteries (two .6 Volt Penny Pill Jars in Series) and it made the Led Brighter.
                    - the Pill Jars have...   a Bolt in the middle---> covered in Paper Towel--->Surrounded by 50 Pennies---> Immersed in water.

               2.  I made a Nantucket Nectar Bottle Cell... does put out same Voltage...and maybe double the Amps.
                   - I made it with a Longer Bolt and about 500 Pennies.
                   - The Pennies are new ones... so they are only coated with Copper ;o/... Zinc is on the inside.
                   - I also found out that the Steel Bolt is coated with Zinc.

              3.  I discovered the Batteries run best filled about 10% to 20% with Tap Water. (Haven't done any acids in the water)
                  - So capillary action keeps the Towel wet above the water line. (batteries are Upright.. had them on the side for awhile)

A few more small improvements and the Penny Pill Jar Lamp will be a certain reality. ;o)   (see above)

Best Regards,
                      The Observer

this is just an idea but could you use a peace of copper pipe with plastic stop ends and thread the zinc bar thru both ends and see what you get from that white viniger at a 50 50 mix could work very well

wooooooooohoooooooooooo i am finerly done catching up on this thread thank god for that lol

jeanna  & electricme a big congraterlations are in order you have both done it light a house with low voltage
from what i read you also could run this off your earth bettery experements

now my idea what if you were to disconnect the lighting circuit in your house fuse box and then power that circuit with the jt
with all light fittings haveing the led ones you could easy move from room to room

@all
IMPORTANT TIP?
Make daily CD ROM backups!!!
Now I know why I like to work on borrowed computers.  My SanDisk is around my neck on a lanyard all the time.
--Lee
Okay, there's a problem with this:
The SanDisk is exactly the same in function as a computer hard drive.  Even if you back up your data regularly, those files can still disappear after you log off the computer.  Mine did.

Printing off hard copies of your data will eliminate this problem, even though it can get expensive for big files or a lot of data.

I have 3 hard drives running on my computer, the master and then I back up to the other 2 and also run a 2 gig. flash drive as well.  I have never, ever lost any data.  I know there is always a first time but, with a little forethought and care, you can preserve your data.  PS  Do not get flash drives near any magnets, the same with hard drives as well.

@Bill (Pirate88179)
With respect to your reply #13770:
I respect your experience as far as it goes.  I believe you have the truth by what you know.  However, as a former electronic/computer technician with professional experience in electronic R&D, my experience is simply different.

I did nothing different to the data that would cause it to disappear.  That's not all:  I had only one file that wasn't an aerospace reference .PDF   It concerned a statement of fact in .DOC to present to the V.A. in order to upgrade my non-service connected pension.  It was still on the disk.  Someone selectively deleted all my backed up aircraft specification files.  Only that one was left.

Please keep in mind:  Cap-Z-ro has a point that there's a conspiracy do keep certain information from the public.  I've become acquainted with the proof.  Cap-Z-ro is correct in his assertion when it comes to that.  But, that's all I'll say.

Print off a hardcopy of whatever drawings and electronic test results you think are important.  Your computer isn't software safe,  regardless!  of how good your antiviral software is.

after what happened to my files aka the hacker deleting things i keep copys on things not connected to my pc resently just starting makeing a book also for the info you never know they maybe a time they is no power the eletronic data ant much use then now i do have a good memory but things i dont seem to do for a long time to tend to go missing in my memory like playing guitar i did it for 10 years recenty picked up up after about 11 or 12 years and well couldent ethern remeber how to make a cord lol this also seems to have happened with other data maybe this is down to my bike accident i ant sure just know that stuff i dont do for as long time seams to slip
