"Voltage Multipliers are the circuits where we get very high DC voltage from the Low AC voltage supply, a voltage multiplier circuit generates voltage in multiple of peak input voltage of AC, like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output, in case of Voltage Tripler circuit."

"Remote garage door openers are great but there were times I need access to the garage and did not have the remote with me. I therefore designed a simple keypad with 4 digit access codes to allow myself, my family and friends to gain quick access to the garage when a remote is not at hand."

"I always thought the clapper was so cool. For those who are lazy like me, turn on or off the bedroom light without getting out of bed, simple clap your hands is amazing. Thinking about it I projected one for me. Several projects of clappers can be found on the Internet, and most of them do not use microcontroller. I chose to use a micro planning future updates, such as turn on or off the light with 2 claps, the TV with 3 claps, DVD player with 4 and so on. Another update can be a time to turn off the device automatically."

"I’m planning a trip to the desert, and one of the things I wanted to make for myself were time lapse movies of sunrise or sunset, and the night sky. My DSLR does not have a wired remote capability and Hoya has decided not to include an interval timer on their low end DSLR….."

"A modular electronic drum kit that allows recorded samples to be used as drum sounds. We decided to build a modular electronic drum kit because we thought it would be an interesting project to be able to record ourselves and use our own voices or sounds as drum noises."

"This 5×5 LED Display Snake Game is the first stepping stone to a fully functional 3-D snake game on a 5x5x5 LED Cube which will be built in a future project. This introductory project serves to provide experience for soldering the LEDs and creating a framework for the more involved LED cube."

"Daniel Ballou and Dashdot are developing a system that transforms the humble cinder block into a high fidelity speaker. Concrete is a low resonance material that minimizes vibrations and reduces coloration of pure sound delivered by the drivers. A drawback of course is that it’s heavy to handle and ship, and labor intensive to mold."

"We are working to develop an open source hardware datalogger that can be placed in the field for extended deployments and measure common water parameters like temperature, conductivity, depth, and turbidity. There have been several iterations of the hardware, including a version based on an ARM chip."

"A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI’s pins for experimentation. The interface board was designed to be simple and used for initial experimentation. It can be built on a single-sided PCB using home-made PCB fabrication methods."

"The controller uses an ATmega328P, the same as used on the ‘Arduino uno’. This makes it very easy to adapt the Arduino platform on the controller. You can upload your sketches via the usb port. The hardware and software is open for everyone, this makes it possible to program your own functionality into the controller."
