[Acorv] wrote in to tell us about his latest hack, a robotic arm that writes with a marker. In the video after the break, the arm is set to copy whatever someone writes in a touchpad. As you might guess from this video, the hack is written up in Spanish, but it’s nothing your favorite translator can’t handle if … Read the rest
We’re happy to see Arduino enthusiasts championing the use of smaller hardware when the need for a full-blown ATmega-based board just isn’t there. [Chris] has been doing just that, using ATtiny85 chips in his projects. But he’s tired of hooking jumper wires to flash the sketches. He finally got around to etching this ATtiny85 programming adapter.
If the project … Read the rest
We’ve spent some serious time building robot chassis and motor controllers. [Whamodyne] does the smart thing and scavenges what he needs form cheap sources. He picked up an RC car from the local pharmacy for just $10, tore the body off and behold, a bounty of robot-friendly parts.
We’re not talking precision parts here, but we don’t scoff at two … Read the rest
Today we stumbled upon [jimthree's] Seismic Reflector while looking at projects that employ the Processing language we mentioned a few days ago. Utilizing a Boarduino and some vibration motors from a game controller, the Seismic Reflector does just as its name implies – rattles itself around whenever there is an earthquake. While this does seem a bit silly at first, … Read the rest
[Cyberspice] informs us she likes snakes. Hey, who doesn’t? She’ll soon be adopting a lovely ball python and wanted to keep close tabs on the sensitive creature’s environment. To that end she assembled a network-enabled vivarium monitoring system based on Adafruit’s Boarduino (a minimalist Arduino clone), a TMP36 analog temperature sensor, Saelig’s WIZ810MJ Ethernet interface, and a common LCD … Read the rest
Solarbotics recently released its own version of the Arduino microcontroller development board. They based their board on the Freeduino design. We thought this would be a good opportunity to review the new board as well as present a How-To about building a simple binary clock. Along the way we’ll cover some basics on attaching LEDs and switches to a … Read the rest
