From the MAKE Flickr pool Flickr member svofski made this rather sweet touch-sensitive keypad with backlighting – This a custom implementation of capacitive sensing technlogy as per QMatrix Whitepaper. It uses an ATmega8 to scan the keys and outputs ASCII characters to the serial port. Schematic, PCB, and source code are available, though the project […]
From the MAKE Flickr pool Flickr member Recotana brings good news for Arduino users in the form of a new code library which facilitates control via the network optimized OSC data protocol. The above video demonstrates basic functionality using the iOSC app for iPhone OS, but the library could be used with any OSC software […]
From the MAKE Flickr pool Furan dug into an LED message scrolling badge to gain custom control – This is one of those el-cheapo led nametag badges. The inside of the badge had one of those gloptop chips between some pads for a smt chip, so I dremeled out the gloptop, reverse engineered the schematics […]
A brand spankin’ new big brother to the Duemilanove, the first pic of a new Arduino board has surfaced. The Mega uses an ATmega1280 surface mount chip and offers a whole big bunch of new features – 128KB of Flash 4KB RAM 4KB EEPROM 53 IO 4 HW UARTs 14 PWMs I2C bus 16 Analog […]
Joe Grand writes in with plans to build his POV wristwatch (mentioned here a while back) – Five years ago, I designed a prototype for a wristwatch based on the phenomenon of persistence-of-vision. Being a longtime runner, I thought it would be cool to be able to run at night without fumbling with my watch […]
From the NYCResistor crew comes this action-packed crash-course in capacitors – complete with a cliffhanger ending! Here’s hoping the saga continues with a miniature rescue mission via shrink ray (they must have one in their somewhere, right?) If after that, cap functionality still seems a bit fuzzy, check out this rather helpful little web demonstration […]
MAKE subscriber mtbf0 used a MiniPOV kit to create this rather sweet UV printer – This is a video of a phosphorescent text display that needs a name. It’s a minipov3 board with uv leds. It has a built-in 5×7 font and room for over 900 characters of display text. When passed over a phosphorescent […]
