I got this from a LED flashlight and i want to by a circuit board like this to put IR LEDs in it.

I’m fixing my LCD monitor and stuck at this junction.

What are the parameters (e.g. voltage, current or energy requirement) to be considered for designing a wireless device capable of communicating at 2.4 GHz or higher for use in a class 1 gassy environment. Please also give the details of the maximum or minimum levels for the parameters.

Hello everyone.

I have to extract the main idea of the following text, but I’m utterly confused. Take a look:

Computers are electronic machines for processing data. Data are pieces or items of information that have been proper prepared so that the machine can work with them. Processing means handling or manipulating the material that has been presented to the machine in such ways as performing calculations, classifying information or making comparisons. A computer is made of millions of electronic devices that can store the date or switch them through complex circuits with differentes functions at incredible speeds.

The collection of devices that constitute a computer are technically known as a computer system. This system consists of functional components, or parts, for input, storage, control, processing, and output. All general-purpose computer systems has these components, but their physical characteristics may vary

The main storage, control and processing components constitute the heart of the computer system. The central processing unit (CPU) has been designed by the manufacturer to control and carry out basic instructions to that particular computer. It is here that the data processing is done. The C.P.U has two components, called the control and arithmetic units. Input and output are handled by machines that are called I/O devices.

What confuses me is that I do not see a real main idea, except for the components of a computer.
So, what do you think is the main idea? (I have to underline it)

Thanks in advance

My trusty old 60GB Zen Vision M seems to have died for the last time. For several years I’ve been dropping it at least once a month, and it held up great. Once in a while it’d start skipping in a video and I’d open it up, reinsert the hard drive ribbon, and voila! Good as new (minus a few scratches). But this last time it gave me a firmware error message, and even after reloading the firmware it still wouldn’t work. I tried my usual fix, but nada. So I tried something else and somehow in all this the female battery connector on the circuit board broke off. I tried using glue (it was late, I was tired, and had no soldering iron…Idiotic, I know…), but while it worked for a few minutes, it broke off when I closed the thing up again, and I don’t know how to get the glue off (Loctite Super Glue) so that I can try soldering it back in place. If you know how to get superglue off electronic parts PLEASE let me know. Otherwise, where can I get just the connectors?

PS how can I anonymously post a picture of the part online?
PPS It’s a Li-Ion battery, charged the same way as an iPod.
Here are pics of the parts, f=female part, m=male; sorry, the photos are not great quality..

I was hooking my 360’s DVD drive up to my motherboard via a SATA cable– and the dvd drives SATA port totally ripped off from the PCB. The spot where it was soldered in was completely stripped down to the plastic. I need to somehow get the SATA cable wires connected to the PCB again, even if it is a permanent connection.
Luckily all of the paths on the board have thru holes I can use, but Im not sure if they can be used as solder points. I could only come up with 2 plans to get this dvd drive working again, either use the strands from a straned wire I completely stripped to try to solder each individual SATA wire to its proper path OR follow the paths to the terminal of the first component and just solder into those since it would still be the same node.
Im wondering if anyone knows any other tips/tricks that I could use that might be easier or just better in general. Im open to trying anything at this point because I dont want to have to buy a new 360 dvd drive for .
Here is a link to a page a threw together to show the damage.

ok, I didn’t relize yahoo would block part of my web address. I have to reveal the black portion in 3 parts so it wont be blocked again……. here it is
a** + *s* + **s
sorry for the 50 additions

the missing connector was actually the power supply and not a SATA port like my original question stated. Its a 12 pin connector with multiple pins going to ground and some are not used.

I bought pokemon Leaf Green off of craigslist and I was trying to play it but every time I try to start the game it says "The 1M sub-circuit board is not installed" and then I can’t save! What should I do?

I just found the answer. It stands for "Resistor Network". Thanks for the input )
