Review: Arduboy FX-C
Arduboy FX-C packs a surprising amount of experiences into a pocket-sized handheld. How could we say no to a review?

Makey Awards 2012 Nominee 12, Atmel, Most Hackable Gadget
Last year, when Phil wrote his widely-read Why Arduino Won column, searching “arduino” on the Atmel website didn’t return even a single hit. Since that time, Atmel has started taking notice, linking out to Arduino resources from their “Education” pages, issuing their own press releases to support important Arduino-related events, sponsoring Arduino-themed contests, and more. They joined us at BAMF 2012 and we are looking forward to seeing them, again, at World Maker Faire NY at the end of this month.
Open Music Labs on the ATmega328p ADC
Here’s an amazing article from Open Music Labs which provides an in-depth explanation of the inner workings of the ATmega328p ADC, and how to squeeze every last bit of performance out of it.
Understanding pull-up and pull-down resistors
When I first got involved in digital electronics, it took me awhile to understand the concepts of pull-up and pull-down resistors and when to use up or down, and when to use internal (built in, programmable) resistors, and when to use actual, discrete component, resistors. On Youritronics (a name that will always make me wince), […]
DIY LED Valentine’s Day heart
The folks at NerdKits, who gave us the DIY Marque LED Array Project, now built on that project with the DIY LED Heart for Valentine’s Day. Using their USBNerd Kit, 20 red 5mm LEDs, and some cardboard, Humberto shows you how to create an electronic Valentine’s heart that twinkles and prints out messages o’ love […]
DIY ATmega168 evaluation board with LCD screen
Dave Prochnow writes on PopSci: Every AVR programmer worth her weight in ATmegas knows about the AVR Butterfly–a ridiculously low cost ATmega169 demonstration and evaluation kit. Lamenting the lack of such a kit for the ATmega168 drove me to design my own demo/eval kit for the Arduino microcontroller family. This project became a compulsion that […]
HOW TO – use Arduino as a high voltage programmer
From the MAKE Flickr photo pool If you should accidentally disable the reset pin while programming an AVR chip, you’ll lose the ability to rewrite to it using common ISP programming devices. To make the chip writable once again, you’ll need a ‘high voltage programmer’ that runs off of 12V. With an Arduino and some […]
