It converts your old phone into a new smart thermostat Bemo

Image
Bemo lets you turn an old phone with iOS, Android or Windows Phone in a modern and intelligent thermostat for your home. We bought a new phone and keep or sell the old (at best), but the company Wise Labs LLC believes that those old phones can be used to automate the home to use as a new smart thermostat with only Bemo download implementation of Android, iOS or Windows Phone, then place it on the wall along with some connections. Applying Bemo leaves control the temperature of your home from the touch screen with a modern and intuitive interface. Wise Labs promises all sorts of functionality and advanced programming and autonomy that allows you to turn the air conditioning when you're on the way home or the like, because that is always connected to the Internet with Wi-Fi connection. Other features would be coming in the future allowing more developers to create applications that work with Bemo, but also is allowing emergency calls to 911 and your Internet connection does not work....

Mobile Phone Travel Charger Circuit Diagram

This is a Mobile Phone Travel Charger Circuit Diagram. At this point is an ideal cellular phone charger using 1.5 Volt ballpoint cells to charge mobile phone while wandering. It can refill cell phone battery three before four period in the field of spaces everyplace AC power is not on hand. A good number of the cell phone phone batteries are rated by the side of 3.6 in opposition to/500 mA. A single create torch cell can provide 1.5 volts and 1.5 Amps current. So if four pen cells are connected serially, it wish form a battery bunch with 6 volt and 1.5 Amps current. while power is practical to the circuit through S1, transistor T1 conducts and grassy LED light. Mobile Phone Travel Charger Circuit Diagram What time T1 conducts T2 furthermore conducts since its dishonorable becomes denial. Charging current flows from the satellite dish of T1. To reduce the charging voltage to 4.7 volts, Zener diode ZD is used. The output gives 20 mA current on behalf of stupid charging. If additio...

Asus PadFone 2 phone in a tablet released with quad core processor and ICS

Image
The PadFone 2 is not only bigger and faster, it is, combined, lighter than Apple's new iPad, add to that one of the most powerful processors in a smartphone and you're onto a winner. Asus has unveiled the new PadFone 2 smartphone and tablet hybrid in Milan today running Ice Cream Sandwich and sporting a larger 4.7-inch HD display and quad-core S4 processor. The PadFone 2 has had a bump in the screen department going up to a Galaxy S3 rivaling 4.7-inches whilst swapping the original OLED panel for an integrated Super LCD which means brighter, sharper and as we've seen in the iPhone 5, a lot thinner. Under the hood is where things get really impressive however as the PadFone 2 sports Snapdragon's new S4 quad-core processor making it one of the most powerful smartphones on the market. There's 2GB of RAM making sure that no matter what you're doing the PadFone 2 won't even break a sweat. The camera has been given a massive boost now offering up 13MP along with F...

USB Powered Mobile Phone Battery Charger

Image
Now you can charge your Mobile Phone from the USB outlet of PC This simple circuit can give regulated 4.7 volts for charging a mobile phone. USB outlet can give 5 volts DC at 100mA current which is sufficient for the slow charging of mobile phones. Most of the Mobile Phone batteries are rated 3.6 volts at 1000 to 1300 mAh. These battery packs have 3 NiMh or Lithium cells having 1.2 volt rating. Usually the battery pack requires 4.5 volts at 300-500 mA current for fast charging. But low current charging is better to increase the efficiency of the battery. The circuit described here provides 4.7 regulated voltage and sufficient current for the slow charging of the mobile phone. Transistor Q1 is used to give the regulated output. Any medium power NPN transistor like CL100, BD139, TIP122 can be used. Zener diode D2 controls the output voltage and D1 protects the polarity of the output supply. Front end of the circuit should be connected to a A type USB plug. Connect a red wire to pin1 and ...

Simple Mobile Phone Battery Charger

Image
Mobile phone chargers available in the market are quite expensive. The circuit presented here comes as a low-cost alternative to charge mobile telephones/battery packs with a rating of 7.2 volts, such as Nokia 6110/6150.   Circuit diagram: Mobile Phone Battery Charger Circuit Diagram   Parts R1 = 1K R2 = 47R R3 = 10R R4 = 47R C1 = 1000uF-25V D1 = LEDs any color D2 = LEDs any color D3 = LEDs any color D4 = 1N4007 D5 = 1N4007 IC1 = LM7806 T1 = 9VAC Xformer 250mA BR1 = Diode bridge 1A Circuit Operation: The 220-240V AC mains supply is down-converted to 9V AC by transformer T1. The transformer output is rectified by BR1 and the positive DC supply is directly connected to the charger’s output contact, while the negative terminal is connected through current limiting resistor R2. D2 works as a power indicator with R1 serving as the current limiter and D3 indicates the charging status. During the charging period, about 3 volts drop occurs across R2, which turns on D3 through R3. An e...

Nokia could launch entry level Windows Phone 7 5 handsets says report

Image
Nokia may offer entry-level Windows Phone 7.5 devices by year's end, according to DigiTimes. Citing the usual "industry sources," DigiTimes said the new phones would be aimed at consumers in emerging markets, who are considered more price-sensitive. The hardware requirements for Windows Phone 8 are stricter than those for its predecessor, demanding a dual-core processor and support for near-field communication (NFC). Those features would be difficult to add to more entry-level and mid-level phones, according to the sources, prompting the need for less pricey Windows Phone 7.5 devices.

New Liquipel – Make Your Phone Watersafe

Image
Liquipel™ is a revolutionary process that applies a watersafe™ coating to your electronic devices to protect them in the event of accidental exposure to liquids. It is not visible to the human eye, virtually undetectable and Liquipel™ will not compromise the look, feel, and performance of your electronics. Liquipel™ is a Nano-Coating that is applied though a propriety process. This process starts by placing devices into the chamber of the Liquipel™ Machine. The Machine then removes all the air to create a vacuum, a special formula is then introduced as a vapor. The vapor then permeates the entire device inside and out, Liquipel™ then bonds to the device on a molecular level, leaving your device watersafe™ for years to come. Check out our GITEX 2012 Trade video coverage to see Liquipel in action.

This is a simple PIC Security System Dials Your Cell Phone Circuit Diagram . Do-it-yourself phone dialer security system calls your cell phone, office etc. whenever a door or window is opened, or panic button is pressed. Great Home Alarm. PIC Security System Dials Your Cell Phone Circuit Diagram The circuit consists of a small PIC microcontroller, assembly program, and a few other parts to detect a switch closure from an open door, window, or manual push button and then dial the cell phone number, and transmit a steady tone to indicate the source of the call. The circuit uses the pulse dialing system to interrupt the line connection a number of times to indicate each digit. Pulse dialing (the oldest form of dialing) works by actually disconnecting or "hanging up" the phone line a number of times to indicate each digit. For example, the digit "5" would be dialed by disconnecting and reconnecting the line 5 times in short intervals of about 100mS. There is about a 1 s...
