Fresh hacks every day
Here's a quick and easy little robot with a not-so-pint-sized brain. [Dikos] over at grobot, slapped together some gutted micro servos, an Arduino pro mini, H bridge chip, and a solar key-chain charger to make this little three wheeled cutie. The robot boasts some very simple object avoidance thanks to the Sharp GP2Y0A21YK analog IR distance sensor, and that's about it. This leaves tons of … [Read more...]
Reddit user [davvik] made an album to show off his custom all aluminum longboard. The whole setup weighs about 12lbs, which is not exactly light for a board. In spite of the added weight [davvik] comments that it is actually pretty responsive. The design is not uncommon but seems to have opted out of the speed holes in favor of structural rigidity, and frankly we love it. We might not risk … [Read more...]
We all know that our precious cruisers/warships/assets can not fall into the wrong hands, and what better way to assure that information security than incorporating a self destruct button into the design? While the general premise is simple enough the only real way to make sure some crazy space-virus can't infect your captain and force him to destroy your ship is to add a two button security … [Read more...]
Last summer we got to have a little chat with [Aaron Taylor] about his automated Gamelan orchestra, Gamelatron. The robotic orchestra features a large collection of Indonesian gongs, metallophones, xylophones and cymbals actuated using simple pull solenoids attached to mallets. Gamelatron's custom controller activates the various 24V solenoids using MIDI, the whole thing is essentially a … [Read more...]
[Ch00f] has decided to ring in the new year with some el wire Kanye glasses. Technically the term for the glasses is either "shutter shades" or "slatted sunglasses", invented around the 80s by [Alain Mikli] and originally given the nickname "Venetian Sunglasses". Kanye West evidently got his own retro redesign by the original creator and the rest is history. That is enough Wikipedia for now. … [Read more...]
[Brad Graham] wrote in to let us know about his electric bike data dump over at atomiczombie.com, written just for us! Last we heard from [Brad] he was building some serious robots and freakishly tall tallbikes but since the weather has turned for the chilly its time to focus on indoor projects. Using a combination of robot parts, electrical conduit, and OEM bikes for the frames [Brad] takes us … [Read more...]
OK, year-old pop culture references aside [Kyle] dropped us a line to show us his tutorial on using interrupts with your Arduino. Given the single core nature of your average Arduino's AVR you pretty much have two choices for monitoring occasional un-timed inputs: Either check an input at an interval (which risks missing the signal entirely) or set up an interrupt to pause the chip's normal … [Read more...]
