The Equinox clock is made up of simple parts but a combination of fine design and precision make it a gem of a timepiece. The guts are made up of an Arduino, a DS1307 real time clock, twelve LED drivers, and sixty RGB LEDs. These combine with a capacitive touch interface to tell the time [...]

[Sk3tch] rigged up a way to use an original NES controller with Android. He bought the controller and a breakout board for it at DEFCON. By combining the controller, an Arduino, and a blueSMIRF BlueTooth module the controller can be used as a keyboard on his Android device. In the video after the break he [...]

When the tipline popped up with this LED suit, part two, by [Marc DeVidts] we were expecing a simple led version of the previously known EL coat. Well we were right and wrong in the same instance. Correct in that like predictions, the outcome is stonking great. Wrong in that this suit far outpaces EL [...]

This peculiar setup allows [Ben Krasnow] to control an alternating current device using one pin on a microcontroller. He’s experimenting with a power drill and has relocated the trigger circuitry that makes it spin. On that board he found a variable resistor combined with a capacitor which control a triac, actuating the speed of a [...]

[Manuel] built his own thermal printer based around an Arduino. We’re a bit confused about the parts, his webpage specifies an EFA-1019HW2 print head but the bill of materials on his github shows EPT-1019W2. We can’t find a source for either product number, but we did find similar thermal line printers for as low as [...]

[FlorinC] sent in his DWex Arduino watch, with intentions for it double as an experimenting base. Inspired by the MakerBotWatch, it runs an ATmega328P, DS1337 RTC,and 24 LEDs to display the time. [FlorinC] tells us the (yet to come) case and strap will be similar to Woz’s watch to ensure airport security tackles him. As [...]

There was a time when a drummer would grab some sticks and lay out a groove using the items around him as instruments. [Lsa Wilson] would rather not work quite that hard and has chosen to do the same thing by tapping on an iPhone screen. As you can see in the clip after the [...]

Who knows if this works and should you really want to try to induce hallucinations by flashing colors in front of your eyes? But we do love the zaniness of the project. [Everett's] homemade hallucination goggles come in two flavors, the small swimming-goggle-type model and the heavy-duty trip visor made from welder’s goggles. Each brings [...]

We have gotten a number of Arduino tips in the last couple days, and we thought we would combine them for your convenience. The first tip we received was for some hints provided by [Bill] on some digitalWrite() alternatives. Similar to some previous research we covered, this tip also includes some tips on how to make the [...]

An Arduino with 40 lines of code, a temperature resistor, and servo are all that’s truly needed to save some dough with this thermostat by [Peter Hamilton]. LEDs and a potentiometer are added as well to help set and read the desired temperature. With or without said additional parts, the hack is still ridiculously simple [...]

A hackathon by the engineers over at Yelp produced this iPad-centric beer fridge. A thirsty dude bellies up to the contraption, swipes his or her RFID card, then dispenses a glass of frothy goodness. The iPad display shows information about what’s on tap, and allows you to give it a rating. This is based on [...]

[Render] says his coat is simply “enhanced with EL wire”, but we know the truth. He’s secretly an alien that can’t block out all of his glowing green skin with a the black coat. No? Fine, You can put away the sewing machine, [Render] simply used a needle and fishing line to attach ~50-70 foot [...]

What he came up with eclipses the wine cellar temperature monitors we’ve seen before. He picked up pH, temperature, carbon dioxide, alcohol, and relative humidity [...]

[Danny] has been working on an RNET to Sonos bridge. These are devices from two different manufacturers used to facility whole-house audio systems. Usually there’s a main controller with a large color screen and then several satellite controllers like the one above which have some of the features but at a lower cost. Normally you’re [...]

Hackers [Navic] and [K.o.D] have fitted an Arduino Pro Mini and an array of components into an off the shelf rocketry kit to create a guided model rocket, taking the whole idea of Arduino-based space technology to another level The Arduino reads signals from internally mounted accelerometers, and adjusts balsa fins (via 4 micro servos) [...]

In an effort to improve his marital standing [Tech B] hacked an air freshener to make it Internet controllable. The main component here is a Glade Sense and Spray. It cost him $7 and is meant to spray out some sweet smells when it senses motion in the room. The unit also has a manual [...]

A USB host shield handles the HID end for connecting the mouse. The video after the break says it all, [Oleg] [...]

[Reza Naima] has been using an Arduino as the center of his CNC setup for quite some time now. It handles three stepper motors, limiting switches, e-stop, and spindle control. The sketch he’s using allows him to stream g-code to the popular prototyping platform, freeing him from needing a dedicated PC. It’s worked so well [...]

This LED matrix is arranged in a 24×6 pattern for message scrolling. There’s no etched boards here, making us wonder where [Syst3mX] found protoboard this long. He’s using an Arduino to drive the demonstration (clip after the break) but you can use any microcontroller with this setup. That’s because he’s using three shift registers for [...]

It seems everybody has a different interpretation of the perfect alarm clock. [Loic Royer's] alarm clock is not the loudest, or the smartest, but does have some interesting features. By monitoring several environmental factors like temperature, air quality, humidity, dew point, and your own sleep patterns, this alarm clock can determine the best moment in [...]

This simple yet precise build takes your camera for a spin in order to take spherical and multi-row panorama photographs. The rig mounts to a tripod, using two servo motors for motion, producing images that can be stitched together perfectly. An Arduino handles the hardware with an LCD interface for dialing in the settings.It’s not the cheapest [...]

[Andres Guzman] is chauffuering himself around the University of Illinois campus thanks to his wirelessly controlled mountainboard. He added a brushless motor to drive the rear axel with the help of a chain. Power is provided by a Lithium Iron Phosphate battery which we’ve seen used in other electric vehicles due to its lightweight properties. [...]

[John Sarik] asked himself why a project should only have a handful of Nixie tubes? Without a good answer to his query he went ahead and built this Sudoku game using 81 Nixie tubes. There’s not much of a description for his work but here’s how we think things go: The two knobs manipulate a [...]

This touch screen relies on measurements from two range finders to track your finger as you press buttons. [James Alliban] put this together as his first Arduino project. We’re familiar with [James'] background because of his informative augmented reality business card. As the Arduino picks up data from the range finder it sends it to a Flash [...]

While hacking a wireless presenter doesn’t sound like something worthwhile or interesting, [Niels Teusink] demonstrates that these little devices often are a lot more powerful than we give them credit. With an Arduino, plenty of research, and some heavy sniffing of a wireless presenter’s SPI and then wireless interface [Niels] is able to emulate an [...]

Regular Hackaday reader [Osgeld] is at it again with this USB conversion for an NES controller. This is a ubiquitous hack that we started seeing very early on, sometimes involving an adapter kit, and other times including things like a thumb drive and USB hub. But this time around is truly a bare-bones version. He’s using [...]

This interesting box of buttons is a talking poker tournament timer. Full of useful tools like a binary time display, words of wisdom, countdowns to the end of the game, and even good old “bicycle built for two” mode (around 1:20). While we find it fairly difficult to understand, we applaud the feature list, especially [...]

When he tipped us off he mentioned that this is Arduino powered and uses a hall effect sensor. There’s not talk of this in his writeup but we [...]
