I just bought a new dirt bike tube and accidentaly put a hole in it with the tire iron putting it in. I know that they have patch kits out there, but I'm too cheap to buy one unless at last resort. I figure I already have enough rubber from an old tube to cut out a patch, and glue it on. I'm wondering if this will work good, and if so, what type of glue would I want to use?
y (- 0.12822) * (x^2) + (0.32492) * (x) I feel your pain Hd, but not even the function helps with the damn user interface because the graph is on a grid with a y-axis scale of (0.01) and an x-axis scale of (0.1).
Its pretty stupid as all chain letters are, by the way it would have been much better if proper grammar and spelling were used -.-
The disc (CD or DVD) is coated with a reflective material. The writing process makes certain parts of the material non-reflective (permanently for normal CDs and DVDs, and temporarily for rewritable discs). Then, the laser (really a laser diode) focuses a beam of light onto the surface of the disc. The reflected light is detected by a photodiode a device that modulates the current it allows to pass based on the amount of light incident on it. So the digital information on the disc causes the photodiode to modulate its output current, and it is this signal that the CD or DVD player converts to music. As far as lasers in other entertainment things: I'm not aware of any other entertainment devices that use such lasers. There are lots of industrial uses for them (bar code scanners being the most common).
