Automated Pocky Dispenser

Sometimes, along comes a build project that is not so much a fail, as how not to do it. First off, some of us here had to look up what a Pocky is, never having heard, seen or tasted one “ seriously. Once satisfied, we turned our attention to [Michael]™s Automated Pocky Dispenser. Took a while for us to figure out if it™s useful or not. But it™s a fun, quick project that [Michael] put together in around an hour using parts lying around in his office.

For those of you who™d like to know, a Pocky is a chocolate-coated ¦read more

Hackaday Links: March 1, 2015

The somewhat regular Hardware Developers Didactic Galactic was a few days ago in San Francisco. Here™s the video to prove it. Highlights include [James Whong] from Moooshimeter, the two-input multimeter, [Mark Garrison] from Saleae, and a half-dozen other people giving talks on how to develop hardware.

[Taylor] made a portable NES with a retron, a new-ish NES clone that somehow fits entirely in a glop top IC. The controllers sucked, but [Taylor] made a new one with touch sensors. All that was required was eight transistors. The enclosure is an Altoid tin, and everything works great.

Sensorino wireless home lighting with Arduino

Home automation exists for a while (since the 90's?) and has been quite expensive but with the advent of Arduino and above all cheap sensors, relays, other components from Ebay there's no longer any inherent reason for a maker not to automate their home.

Putting Oculus Rift on a Robot

Many of the early applications for the much anticipated Oculus Rift VR rig have been in gaming. But it™s interesting to see some more useful applications besides gaming, before it™s commercial release sometime this year. [JoLau] at the Institute i4Ds of FHNW School of Engineering wanted to go a step beyond rendering virtual worlds. So he built the Intuitive Rift Explorer a.k.a IRE. The IRE is a moving reality system consisting of a gimbaled stereo-vision camera rig transmitting video to the Rift, and matching head movements received from the Oculus Rift. The vision platform is mounted on a Remote-controlled robot ¦read more

Cardboard CNC Machine Boxes Up both a Tool and a Framework

Want to build up a desktop CNC machine without breaking your pocketbook? [James Coleman], [Nadya Peek], and [Ilan Moyer] of MIT Media Labs have cooked up a modular cardboard CNC that gives you the backbone from which you can design your own machine.

The CNC build comprises of design instructions for a single axis linear stage and single axis rotary stage with several ideas on how to combine multiple of these axes together to construct a particular machine. Whether your milling wood, laser-engraving your desk, or pipetting your bacteria samples, the designs [Dropbox] and physical components can be adopted for ¦read more

Reverse Engineering Wireless Temperature Probes

[bhunting] lives right up against the Rockies, and for a while he™s wanted to measure the temperature variations against the inside of his hour against the temperature swings outside. The sensible way to do this would be to put a few wireless temperature-logging probes around the house, and log all that data with a computer. A temperature sensor, microcontroller, wireless module, battery, case, and miscellaneous parts meant each node in the sensor grid would cost about $10. The other day, [bhunting] came across the exact same thing in the clearance bin of Walmart “ $10 for a wireless temperature sensor, ¦read more
