MiniDVD is a DVD disc 80 mm diameter in size. In standard DVD quality, it grasps 30 minutes of video or 1.4 GB of data. In SLP mode, it can hold 120 minutes of video when compared to VHS quality. It is normally used in camcorders. But the 80 mm size was originally used for music CD singles. It can be able to playing back in the majority DVD players that are tray loaded. The trays on DVD drives and players have an inner ring in which the 80mm disc in centered for loading in the player. This format cannot be used Slot loading players. The format is also known as a DVD single, or video-single, being equivalent to the CD single in being a singles format for music videos. MiniDVDs are known also as "3 inch DVDs," referring to their estimated width in inches.

We have four types of digital cameras.They are listed s follows.

• Compact digital cameras
• Point and shoot cameras

Is there any possibility of lightning enter on a cell phone and blow you?

Avoid using a corded telephone for the period of a lightning storm.You can chat away on a cell phone or a cordless phone at lightning storm because there is no direct path between you and the lightning.

According to the National Weather Service If you are using cordless phone bit, lightning can struck the line at the time you picked it up from its base, and it possibly will harm you.

Likewise, if you were using the phone close to the base while lightning zoomed through your lines and into your phone’s base, the current may arc through the air to your phone.

A classic SIM having 19 digits say for example 75 91 12 1000 01 314567 0, offers quite a lot of details as given below:

• The first two numbers (75) refer to the Telecom Id.
• The next two numbers (91) refer to the country code (91-India).
• The next two numbers (12) refer to the network code.
• The next four numbers (1000) refer to the month and year of manufacturing.
• The next two numbers (01) refer to the switch configuration code.
• The next six numbers (314567) refer to the SIM number.
• The last numbers which is separated from the rest is called the check digit.

A barcode reader is an electronic tool for evaluating printed barcodes. Similar to a flatbed scanner, it consists of a light source; a lens and a photo conductor which converts optical impulses into electrical ones. Moreover, all barcode readers include decoder circuitry examining the barcode's image data provided by the photo conductor and transferring the barcode's content to the scanner's output port.

Scanning methods:

• Pen type readers
• Semi-automatic handheld readers
• Fix-mount readers for automatic reading
• Reader gates for automatic scanning

Rechargeable alkaline battery is a kind of alkaline battery that can be rechargeable. The first invention of rechargeable alkaline technology was developed by Battery Technologies Inc in Canada and accredited to Pure Energy, Rayovac and Grandcell. Subsequent copyright and progress in technology have been introduced by Pure Energy, the remaining maker of rechargeable alkaline batteries. The shapes consist of AAA, AA, C, D and snap-on 9-volt batteries. Rechargeable alkaline batteries have the capability to hold their charge for years, not like NiCd and NiMH batteries which self-discharge in 90 days. If produced accurately, rechargeable alkaline batteries are an environmental friendly form of energy storage. At present pure energy rechargeable batteries are cast-off into fertilizer for the corn and potato industry by RMC recycling in Canada.

Battery recycling is recycling actions that try to decrease the quantity of batteries being disposed as municipal solid waste. It is extensively promoted by environmentalists worried about pollution, mainly of land and water, by the accumulation of heavy metals and other toxic chemicals from batteries.

Most types of batteries can be recycled. Though, some batteries are recycled more willingly than others, such as lead-acid automotive batteries (97% are recycled) and button cells (because of the worth and toxicity of their chemicals). Other types, such as alkaline and rechargeable, can also be recycled.

These batteries include but are not limited to: Car Batteries, Golf Cart Batteries, UPS Batteries, Industrial Fork-Lift Batteries, Motorcycle Batteries, and Commercial Batteries. These can be regular lead-acid, SLA, Gel Type, or AGM batteries.

A camcorder is a handy consumer electronics tool for video recording video and soundtracks using an integrated recorder unit. The camcorder include both video camera and video recorder in single unit, hence its compound name. When we match with previous technology, an acquisition and recording devices would be separate.

The most primitive camcorders which were developed by companies like JVC, Sony, and Kodak, used analog videotape. From1990s recording onto digital tape has turn out to be the standard. But from early 2000s tape as storage media is being slowly replaced with tape-free solutions like optical disks, hard disk drives and solid-state memory.

All tape-based camcorders have detachable media in form of video cassettes. Solid-state camcorders can have neither removable media in form of memory cards, nor built-in memory, nor both. HDD-based camcorders generally have non-removable media in form of a hard disk drive.

Camcorders that don’t make use of magnetic tape are frequently called as tapeless camcorders. Camcorders which use two different types of media, like built-in HDD and memory card, are repeatedly called as hybrid camcorders.
