For detecting weapons it is rather simple to use ordinary metal detectors. A detector which would be able to indicate the size of the metal object and type of the metal detected, so you can quickly tell small metal objects like coins from large metal objects like guns.
As for chemical detectors of explosives and such, the most common detector is a sniffing dog and his guide and the most precise and sensitive detector is a sniffing dog with his guide. Plus dogs have their own intelligent decisionmaking and can learn a lot.
Where to get a diagram for a dryer belt installation?
Sears has a good repair site on the web. The model number must be entered and it has good pictures. Bacically those belts went over the top of the drum to a spring loaded tensioner pully on the front bottom right side then up to the motor pully and back up the right side. Remove the front panel of the dryer with a yellow handle nut driver or 3/16 socket to access the belt.

It sounds like your (HDD) hard disk drive is faulty. Your hard disk drive is responsible for storing your operating system, along with all your files and programs.
When it's under too much stress (fault problem) then it begins to freeze up and your system takes a while to load programs and files.
As I am aware, the HDD is the only culprit inside a computer to make a buzzing noise due to how it operates (sort of like a record player, a disk inside with an arm).

How is sound transmitted and revived via telephone?
Cable connected landlines, rely on a DC voltage (about 24vdc) when connected on line (receiver lifted).
The microphone (mouthpiece) causes this DC voltage to alter in time with the audio. The receiver is a small loudspeaker, which causes the diaphragm to vibrate as the voltage varies.
How these things are accomplished has changed over the years.
The system that Edison used, and was used up until the 1960's, used a carbon granule microphone and a metal diaphragm earpiece.
The voltage on the line was passed through the microphone, which consisted of carbon granules in a capsule. A tin diaphragm was attached to one end of the capsule. Your voice moved the diaphragm and compressed the carbon, which altered in resistance. As the resistance altered so the voltage varied on the line.
At the other end, the voltage passed through a coil, which attracted a metal diaphragm. As the diaphragm moved, it moved the air near you ear and you could hear what was being said.
It only used two wires, The earpiece and microphone were connected in series.
These days electronics are used. The microphone is an electret condenser microphone, attached to the input of an amplifier. The earpiece is a miniture loudspeaker, attached to the output of an amplifier. The voltage on the line powers the system and also has the audio superimposed on it, via coils and capacitors in the circuit.
Can a 200mw red laser pointer burn paper?
You cannot physically damage a person's eye with a laser pointer. You can however, decrease the activity in the inner eye which relays a signal (blindness) after a period of time while staring into the laser. It is not strong enough to damage, but bright enough to cause dysfunction of your pupil.
Edit-A Class I laser is harmless in normal use, Class IV is extremely hazardous to skin and eyes. It all depends on the laser power.
It can also cause a nuclear detonation.

More detail - I've been given it by a friend, but I don't need to use it as an organiser. Are there any interesting hacks? I'm reasonably handy with Linux and general mucking about with electronics, but I've not found any mention of being able to flash it.
Maybe I'll just use it as a paperweight.
