Here goes the description of my problem!
I feel problem in accessing a page within a thread. For example if I have to go page 17 of 40 pages thread then I have to follow it sequentially.
If any solution could be found then this site will become many folde easier to browse.
Thanks. -
But I can't open more than 5/ 6 pages ata time, If I do, all of them disappear suddenly I have to start again. I don't know what the solution might be. I often get the problem " IExplorer has performed illegal operation and will be shut down by windows" :-[

If you plan to do it yourself then please share the experience at this form. Thanks

Hello Walid!
I think temperature is the most critical criteria to stop charging. If u have lot of experience charging non-rech bats than u can tell us the avg time to charge common cells like AA, AAA or D. It will be usefull -
Hello Friends!
Here is a link to an intresting article, showing procedure to convert ordinary LCD watch into a Wall Clock using light projection

Hello Xenobius!
Can you tell us please which kind of source u r using for load test?
A Generator, transformer or something elese.. -
Hello Xenobius!
I can remember something about the transformer properties. IT says
To change the voltage level
v1= (n1 / n2 )*v2
v1=secondary volts
v2=primary volts
n1=secondary turns
n2=primary turns
similarly it transfers impedence to the other side by!
Z1 = Z2 * (n1 / n2)^2
Z2 = actual impedence at one end
Z1 = Effective transffered resistence at other end.
and u can variation in Z1 with either changing (n1/n2) or Z2
For fixed Z2, using a transformer with taps can help change turn ratio.
An auto transformer can be used for the purpose. ( I have one in my REGULATOR with lot of taps and capable of voltage change upto 50%) -
Welcome Sendebad!
Active filters are used almost in every analog design.
For example audio amlifiers, data converter (A to D and D to A) interfacing circuits, sample and hold circuit, oscilators and so on....
You should refer any OP-AMP Applications book and it discusses a lot of applications. Also any data sheet and application of a certaian IC will help a lot ( u can c for LM741)
This book can be helpfull to u (Operational_Amplifiers.rar) at

Hello Dears!
I would request someone with enough time to search Semiconductor Manufacs Sites for Through Hole Packages(Like PDIP TO's) and make a list of these IC's. I think it will help many of us. -
Whenever I press download button It does nothing.
A page opens to upload some file. Perhaps I have to first upload and then dnload ;)
Anyhow the site seems annoying. Can this site provide a shared password to over form?

Hello Friends!
I want to have all types of electronics related data(especially e-books) in soft form. -
Thanks for the title.
But I am unable to download it from corresponding site. When I do "Save As" it gives no response.. -
you DON'T deserve to replace him
Oh! That was just a joke.
However, like audioguru, I also request to upload the book if someone has it. -
Audioguru, your electronics is vry strong. What is ur major source of knowledge? :-\ Would u like to recommend a good book/study material to me to study. I feel great defficiencies here (although I am BS Electronics engg). Thanks!

Too bad, no book and no moderator for the “Theory articles” column!
Don't worry! I put my services to be the moderator. Just tell me what a moderator does. Perhaps, entice newbies for a tempting title and then flee away! :D -
Please do it as soon as possible ;)

I had the same problem last days but I thought that my favourite site has got an entry in the black list of my ISP ;D ;D. (as most of those fool sites do). But I am satisfied now that it was not the case. I suspect logan_dslasher's picture can cause problems for me any time that way too!
Logan I would ask u to change that sign pic of yours -
Audioguru u mentioned these methods to avoid acoustic feedback/hawling.
1. hybrid transformer
2. voice switching
3. acoustical echo canceller
4. two-opamps bridge circuit
Kindly give the info about last two techniques and provide circuits of possible.
Thank u -
Actually I am annoyed with those bulky high current transformers. Therefore any circuit which doesn't require a transformer is a SOPHISTICATED circuit to me.
I am looking for high capacity, high voltage non-polar caps to increase current capability. -
There r IC's specifically used for dig. data transmission/reception.
TRF6903 (TX+RX) is one such from TI. U can ask them for samles. -
If u r powering the sircuit from AC supply, this circuit might help u for dual supply operation.

What is function of SW1?
Which Amplifier IC used in ckt? -
I tried this circuit.

Hi Logon!
How have you calculated this ratio?
