"The dc motors are used in various applications such as defense, industries, Robotics etc. DC drives, because of their simplicity, ease of application, reliability and favorable cost have long been a backbone of industrial applications. The project provides the efficient and simple method to control speed of DC motor using ATMEGA16 microcontroller and L298N motor driver IC."

"A friend asked me if I could build him a device that would allow him to take photos of his products in 360 degrees. That kind of photo is actually an animation that consists of several photos of the same product but from different angles. It means that we need a device that can be controllable and that could take pictures on even intervals."

"Over a year ago I started to work on a small balancing robot. Between learning more about communication protocols and feedback loops I also had periods of schoolwork that kept me from this hobby. In the end my little robot was balancing on his own and I could send steering and throttle commands wirelessly."

"The purpose of Project 3 was to actually get the quadcopter into the air, and possibly make it autonomously hover in place. Since the copter mechanical design was mostly finished during Project 2, Project 3 consisted mostly of the quadcopter software development and some minor troubleshooting tasks with electronics. In order to control the copter, the team decided to modify AeroQuad software to meet the demands of our configuration."

"A reflow toaster oven and a simple laser cutter. Why a laser cutter? Using a reflow oven makes things easier, but we still have the problem of putting the correct amount of solder paste on the board. This can be done using a PCB stencil."

"We’ve had a couple of rain barrels for several years. At our old house they were mainly used as a source of water for our garden. At the new house, we have much more of a problem with puddles around the house, so the rain barrels are an important buffer for managing the water from large storms. So rather than keeping the rain barrels full all the time, we now want to make sure the barrels are empty before a big rain. This obviously calls for some type of automation system! "

"This project uses an RF receiver module to trigger a pulsing LED Heart when the transmitter comes within range. I made this for my fiance for Valentine’s Day this year."

"A little time ago I made a robotic arm, without the gripper. So last week I draw a gripper that is compatible with a mini servo, I made two versions because I had to chose between two kinds of gears, straight and rounded. Because I first finished the straight gears version I milled this one first, but since there was a little play between the two gears I also made the second one, the one with the rounded gears."

"During my search for a cool design for my lamp, I found this plastic ball that looks like one of those future tellers crystal balls, and I decided to used it in a mystical way. Since my idea became a mood ball, I thought it would be fun to have the mysterious ambient surrounding the future teller’s world, in this case, not future, but present."

"This is the Christmas Tree Ornament I made. It’s a custom PCB that I designed in the shape of a Christmas Tree. The little 8 pin black chip you see on the front of the board is an Atmel ATTiny45 Microcontroller. It has 5 IO pins, and there are 20 LEDs on this board. Each LED is individually addressable through a clever trick known as Charlieplexing."
