"Hardware setup is pretty easy for this, it’s nothing compared to what you’ve just done for the Nerf gun. Grab your breadboard, plug in your Bluetooth module (assuming you’ve soldered some headers onto the six-pin interface), and connect some wires…"

"Recently we had a chance to build a Blinky POV from Wayne and Lane. Or more accurately I should say she had a chance to build it, since my role was limited to talking her through the steps and taking photos. It’s impressive what an 11-year-old can do with a soldering iron!"

"Who has not wanted to vacuum when being away from home? The technique I use is a hack to take apart the remote control of the robot and connect it to an Arduino UNO. To control the Arduino from PC via USB, I use Messenger and lets Eventghost manage all communication with Serial-plugin."

"The Melloman was mostly built in my kitchen…with a Bucket o’ Walkman and a Walkman Army and some breadboarding of the first idea of opto-coupler keying."

"The concept is pretty simple. It is a constant current sink controlled by 2 opamps. Two paralleled logic level MOSFETs do the heavy lifting (heatsink!). Another pair of paralleled P-MOSFETs + a Zener diode act as reverse polarity protection. A capacitor is used to keep the first opamp from oscillating."

"It has 4 digit seven segment display. It can count from 1 to 9999 pieces. (01b) Input can be delayed, so that every input received will block the counter for an amount of time, to prevent double reading on too sensitive item sensors. User can program it to emit an alarm when a number of items is reached."

"An Analog & Digital propeller clock i made! It isn’t Real its just because your so awfully slow!!! 😉 based on an afterimage phenomenon, I.E. the reaction slowness of the retina, the illusion of reality our brains are ‘lying’"

"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."

"The biggest stumbling block to the project was the computer’s interface. The Apple Extended Keyboard II is from the days of ADB, or Apple Desktop Bus. The internet revealed two possible solutions: An expensive and sometimes-hard-to-find adapter by Griffin, or a $16 microcontroller and some DIY elbow grease. Naturally, I chose the latter."

"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."
