10 Ways to Destroy an Arduino

10 Ways to Destroy an Arduino article tells how you can accidentally destroy Arduino board. Use a sledgehammer, fire a bullet at it, throw it into a pool….that’s not what we’re talking about. We’re going to show you how to electrically destroy your Arduino: Method #1: Shorting I/O Pins to Ground Method #2: Shorting I/O

RC servo modification for continuous rotation

A standard hobby RC servo motor is designed to rotate through only 180 degrees. They are most often used in RC applications (like steering). The servo motor controlling is done with servo control pulses (1-2 ms pulse at around 50 Hz rate). More details on the control signals can be found at Servo protocol web

DIY Polygraph Machine for April 1

April Fools’ Day is celebrated in many countries on April 1 every year. It is widely recognized and celebrated as a day when people play practical jokes and hoaxes on each other. Lying is awesome way to get people fooled. Here is one idea how to avoid being fooled: use a lying detector. If you’re

New interesting Arduino platforms

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. The microcontroller on the Arduino board is programmed using the Arduino programming language (based on Wiring and C) and the Arduino development environment (based on Processing). This combination of tools have made it a very easy to use platform for all

Friday Fun: DRM chair

Taking DRM further than it’s gone before. DRM (Digital Rights Management) is something that we often just have to put-up-with in software and digital media files. Obviously DRM is a great tool for companies point of view to make sure we only use software and data as they intended, but outside planned obsolescence, there isn’t


FemtoDuino is probably the smallest 328 based Arduino compatible board around. Those things are tiny: foot print is 20.7×15.2mm. They’re an Atmega328 that is arduino compatible. Hands on with the super tiny arudino: FemtoDuino article and this video give you an introduction to those interesting looking small boards. The downside of them is that they

Arduino Esplora

After I build my Atari joystick to USB conversion I saw news that the folks at Arduino seem to be stepping up their game on the same application area. With the new Arduino Leonardo board able to emulate USB keyboards and mice right out of the box, it seems the perfect time for Arduino designers

Christmas lights with Arduino

I have some years posted links to different Christmas lights project on the net. This year is no different. Here is the first one on this topic. Christmas light controller is its own percussion section article tells that Jason and his father took advantage of a week off of work over Thanksgiving to design and

Arduino Leonardo and Micro

Arduino Leonardo is a pretty new microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed
