Joule Thief

Lee:
Yes I have seen those letter "A"s cropping up in quoted sections around the forums.  I am not sure this indicates some malicious virus attack probably more like some software glitch in SQL or something.  But, I agree, they should not be there.

Can that be fixed?
Wait, you may have a point.  I haven't see that anywhere else but this site, now that I recall.  If it's a glitch, it might or might not get worse.  For a reliable, professional-looking 'Web site presentation, Stefan may want to look into it on behalf of OU.com.
Just a suggestion.

Hi Lee,
I think it happens when a post has been written in a writing program then copy >pasted into the php section.
I see it on my webmail too.

Hi jeanna,
You mean on something like Hotmail, Yahoo! or msn.com?  If so this, is more serious than I thought.

This place is closing.  Will return.

think i have manage to get it to work on 1.5 volt i put a cap were the led and resister is then run the joule thief after that my guess is that with only 1,5 volt the ampage loss is to much so wont power the joule thief but the cap seems to work they may flash to start with till the transistor fully opens

to charging a battery in a day from a solar panel im in the uk my solar panel kicks out about 40ma at best so takes awhile but seems to top up good enough for a full night worth of light i have found better panels on the net a 3.6volt one at 200ma this should do better i did find some 0.5volt 410ma ones these may be better but i will need a few to get the 3.6v - 4v needed to charge a 2.4volt battery bank

and to ubuntu if you ever get stuck google it you csan find most answers there for any problems on ubuntu at moment i am testing a few of the circuit programs to find the best or easyerst one for me to use and yes jeanna your right gimp is the open sorce version of paintshop pro and photoshop

Hi everybody,
I have a new project.
I will be making an IR joule thief.

But it might be a few weeks.
I just learned that I do not have the ir leds anywhere around here, so I need to buy them.
grr.
oh well.....

--------

ubuntu   
The security updates are free too.
And sun open office comes for free and can read and write anything that happens in ms land.
I can read .sls files .doc files and even powerpoint presentations all on sun openoffice for free.
(I can also make them compatible for those still living in ms land. It is easy .)
Gimp is as good as or better than photoshop and as I am learning it is even easier to use.
and...
ubuntu is way faster. I don't know why or how, but it is faster.

@Wilby,
Of course you are exactly right.
GOTOSUB etc...


some musings:
I believe that silicon has a bit of quantum intelligence or is more susceptible to quantum activities and if you hate your computer it will definitely give you a lot of trouble, and if you expect trouble, you will get it. Of course you can do this in your life without a computer, but it seems (to me) that the silicon is a facilitator.

Zhak.
I do not understand what I need to say.
Yes, I was asking about the 1F supercap.
Yes, maybe a schema will help.

@dasimpson.
congratulations! and thank you so much for reading it all. You are a real member of this jt group.
I also want to do this.
I do not understand why it takes so much voltage, unless you are using 2 transistors
I am still manually charging my batteries.
I am using the solar garden lights as rechargers. I use a NiMH in place of the NiCd that they come with and the battery is well charged in one day. (and a well charged battery will last many evenings.)

@Altrez
a patent?
huh?

thank you,

jeanna

Dasimpson:

I bought 3 solar cells last year from, I think it was called the Surplus Shed".  They were like $5 ea. and 1.5 volts @ 1 amp.  I made a solar panel out of them wired in parallel to give me 1.5 volts @ 3 amps.  They seem to work well.
