UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. Today we are going to build a 100 watt 12v DC to 220v AC inverter. This Circuit is simple and very useful.

Coffee Cup Spy Cam
Take your cup of Joe from classic to classified with a tilt-triggered spy camera.The trick is to modify two paper coffee cups — install the device in one, slide it into the second, and align holes cut in the bottoms of each. Two LEDs can be seen through the standard plastic lid — one illuminates when the tilt switch is activated, the other flashes twice after a picture has been taken.

DC Motor Control using Raspberry Pi
Learn how to control the speed of DC motor using Rasberry pi 2 board. There are 40 GPIO output pins in Raspberry Pi 2. But out of 40, only 26 GPIO pins (GPIO2 to GPIO27) can be programmed. Some of these pins perform some special functions. With special GPIO put aside, we have 17 GPIO remaining.

Raspberry Pi Water Cooler
So I decided to build my own. But I wanted to give the gift of easy water cooling to the entire raspberry pi community. I decided to design a 3D printable water block that anyone with access to a 3D printer could build. What if you don't have a 3D printer?

DTMF Controlled Robot
In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. Wwe are here with our next robot that is Mobile or DTMF Controlled Robot. DTMF controlled Robot runs over mobile DTMF technology that exists in Dial tone.

Arduino Frequency Coutner
Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of signal generated by a clock or a counter or a timer. We can use oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency but all these devices are costly and are not for everyone.

Pac Man - an Arduino Game
Pac-man Pac-man Pac-man! Hahaa! If any of you knows what I am talking about, then you must be old enough to know such an old-fashion arcade game, just like me XD (NO OFFENSE). In fact, I started to play those classic Japanese game since I was a little boy, and right now I still feel interesting about it.

Arduino GPS Clock
There are many GPS satellites around the Earth which are used to provide the exact location of any place. Along with the location coordinates (Latitude and Longitude), it also provide other data like time, date, altitude, direction tracking angle etc.

DIY Arduino Phone
Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it’s not such fine as you think, even a little bit clunky, it’s still very cool. That is the point this is a cell phone made by ourselves.
