Laser Diode Module Is it fine to use an 808 nm laser diode with a 780 nm lens and module?
Is this safe to do, and will this adversely affect the performance of the laser?
It won't affect laser performance. I would check the glass index specifications of the lens to see if there is any chromatic shift you might not anticipate or run a raytrace model with lens design code. A 22nm difference in wavelength is not that big a deal.

Im making a high powered laser module hopefully. I have already designed and tested the circuit on a crappy laser diode. What "mw" laser diode will i need to set things on fire like matches and paper and hairs? lol. Anyways, all answers muchly appreciated. Thanks in advance.
yes, sorry i do mean mW ofcourse MW would be extreme. lol. SO anything 50mW and above would be able to set things on fire?
I think you mean mW, not MW, they are very different.
You should know that lasers of this power (probably 50-100mW) are very dangerous. A chance reflection off a shiny object can hit your eye, or someone else's and cause permanent eye damage. Always use the proper eye protection, for you and everyone else in the room, and never use it in a room with windows. Keep it locked up.

High input voltage power supply ...?
I need to design a dc-dc converter that can take an input voltage of 600Vdc and output 12Vdc. The current output is less than 100mA, but I still would like decent efficiency
Perhaps one of the "off-line" type designs used in computer/laptop supplies. Ive seen some rectify 240Vac and drop it to about 18V putting out 50W or so.
Any help finding semiconductors (controller ICs, switching transistors, diodes, etc.) rated up to 600V would be greatly appreciated.
Thanks in advance!
I'm willing to do this in two stages if needed. First convert 600Vdc to any 'reasonable' voltage; then regulate to 12Vdc.
You won't find much rated at 600 volts (you probably need 800 volts rating for a margin). What circuit do you plan on using? I doubt it needs more than a few parts rated for the high voltage. Probably diodes, capacitor and a power transistor. Diodes are no problem, 1N4007, for example. Caps, you may have to put 2 in series.
You can find MOSFETS (IRF830) that are good to 500 volts, and there may be some that are a bit higher. Otherwise you will need to put two in series.

Types Of Mobile Display Technologies
A handset might seem to be just a device tnat lets you zaiK on a cellular network, but actually, there is a lot you need to know about handsets before you go out and buy one. What do you need? What kind of form factors are available? What about the battery? Then, there's the camera to be considered. Also, if a mobile phone is to be really mobile, you need to consider connectivity options. Then there are accessories to jazz up your phone -We round off this chapter with descriptions of a few especially desirable phones.
Display Types
Not only do mobile phone displays show caller information, menu options, contacts, etc., mobile phone displays these days need to be capable of displaying thousands of colours so that high-end features such as images and video playback offer the desired user experience. The followingis a brief on the various types of display technologies in use for mobile phones.
LCDS
LCD displays utilise two sheets of polarising material with a liquid crystal solution between them. Crystals in this suspension are naturally aligned parallel with one another, allowing light to pass through the panel. When electric current is applied, the crystals change orientation and block light instead of allowing it to pass through, turning the crystal region dark.There are two main types of Liquid Crystal Displays: STN and TFT.
STN
Super Twisted Nematic LCDs use the passive matrix screen technology, which has no active or controlling element inside the display cell. Pixels are controlled by energising the appropriate row and column drive lines of the matrix from outside the display, resulting in a slow frame rate. STN screens have limited colour range and viewing angles (~15 degrees max).
TFT
With Thin Film Transistor (TFT) LCDs, each pixel is controlled by one to four transistors. Typically one transistor is used for each of the RGB colour channels. Because of this direct control technique, TFT screens are also called Active-Matrix LCDs.TFT technology provides more accurate colour control, allowing it to display more colours and also offer a wider viewing angle range than other types of LCDs.
OLED
OLED stands for Organic Light Emitting Diode. OLED is a flat-panel display technology that is now being used in a variety of devices. Apart from mobile phones, you can also find OLED screens on portable audio players, car audio systems, PDAs and digital cameras. The basic property of OLEDs was discovered in 1985, over a decade before the first displays were seen. Ching Tang, a Kodak researcher, noticed that an organic material glows green if you pass an electrical current through it.An OLED is made by placing a series of organic thin films between two conductors. They operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. As energy passes from the negatively charged layer to the other layer, it stimulates organic material between the two, which emits light visible through a layer of glass. There must be blue, red, and green light-producing organic material to produce the different colours. Because screens using OLED technology produce light themselves, they do not require a backlight as compared to LCD screens. This means that OLED displays require less power and also can be made very thin. Without any other source of illumination, OLED screens can display bright images that are viewable from almost any angle.Like LCDs, OLEDs also come in passive-matrix and active-matrix flavours.Passive-matrix OLEDs are made up of a matrix of electrically-conducting rows and columns making pixels. Between the rows and the columns are the organic layers. On the other side is the substrate, the material which gives the electricity. The more cur-rent applied, the brighter the display.In Active-matrix OLEDs, there is a TFT back plate instead of rows and columns. This controls the brightness of each pixel. There are two TFT arrays per pixel: one to start and stop the charging of the capacitor, and one to provide a constant electrical current to the pixel. Active-matrix OLEDs consume much lower power than passive-matrix ones.OLEDs have the following advantages over LCD or plasma displays: New-age displays: OLEDs can bring in new types of displays, like ultra-thin, flexible or transparent displays.
Power efficiency:
Since OLED screens do not require a back-i hey require much less power compared to other types of displays. This makes OLED a far better choice for portable devices.

mouse stuttering - help?
xp
microsoft laser gaming mouse
latest drivers for mouse
Im having trouble with my mouse. After the computer's been switched on for awhile it starts to stutter; it takes little micro-pauses as it travels across the screen. These stutters get worse the longer the machine is on for. Ultimately I have to restart to make it usable again.
Ive cleaned the mouse. there's nothing in front of the lens. all the cables are good. changing usb ports makes no difference.
Any ideas? Thankyou.
When the mouse is not getting good response then it is time to consider getting more RAM or doing spring cleaning!
Go through your programs and uninstall, using the built in "add/remove programs" program, junk such as Demos, Games, and software you never use.
Download, Install, and Run: (Google search these)
Cleanup!
CCleaner
Spybot Search and Destroy
Do a full virus scan. If you don't have any Anti-Virus then get AVG free and the Anti-Spyware program too.
Make sure to run a defrag of your C: to finish.
If your computer is still bogged, then check Google for further tweaks. Otherwise, consider your machine out of date or possibly infected with resource intensive malware.
