Arduino Powered Portable Function Generator

Posted on by

It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. There’s something to be said for a bench full of button-festooned test equipment blinking away, it’s like bling for nerds. But just like getting your name written out in diamonds, it can get expensive quick.

Luckily, the hacker has enough technology at their disposal these days that DIY test equipment can help fill your bench without emptying your wallet. [Faransky] …read more

Bucky Glow: Have a Ball While You Practice Coding

Posted on by

About a year ago, [Jonathan Bumstead] built a giant, touch-sensitive, interactive RGB LED geodesic dome that somehow escaped our attention entirely. For this year’s Hackaday Prize, he’s designed a smaller version that’s just as awesome, but a lot faster and easier to build.

The Bucky Glow is great way for hackers of all ages to expand their coding and problem solving skills. This interactive dodecahedron consists of 11 RGB LEDs and a Nano inside 12-sided laser-cut MDF sculpture. The breakout header means you’re free to add interactive bits like a DIY capacitive touch keyboard, IR sensor/emitter pairs, motors, or whatever …read more

Driftwood Binary Clock Is No Hollow Achievement

Posted on by

It’s about time we had another awesome clock post around here. [Mattaw] has liked binary clocks since he was 0 and decided to make one in stunning fashion by using driftwood, nature’s drillable, fillable enclosure.

That beautiful wiring job on the RGB LEDs was done in 18g copper. To keep the LEDs aligned during soldering, he drilled a a grid of holes just deep enough to hold ’em face down. There’s an IR remote to set the time, the color, and choice of alarm file, which is currently set to modem_sound.mp3.

Under the wood, there are a pair of Arduino …read more

R/C Rocket-Beest Burns Up Fuses Out There Alone

Posted on by

We’re beginning to think the “S” in [Jeremy S Cook] stands for strandbeest. He’ll be the talk of the 4th of July picnic once he brings out his latest build—a weaponized, remote-controlled strandbeest that shoots bottle rockets. There are a bank of money shots up on Imgur.

This ‘beest is the natural next step after his remote-controlled walker, which we featured a month or so ago. Like that one, the locomotion comes from a pair of micro gear motors that are controlled by an Arduino Nano over Bluetooth. The pyrotechnics begin when nitinol wire cleverly strung across two lever nuts …read more

Arduino Watchdog Sniffs Out Hot 3D Printers

Posted on by

We know we’ve told you this already, but you should really keep a close eye on your 3D printer. The cheaper import machines are starting to display a worrying tendency to go up in flames, either due to cheap components or design flaws. The fact that it happens is, sadly, no longer up for debate. The best thing we can do now is figure out ways to mitigate the risk for all the printers that are already deployed in the field.

At the risk of making a generalization, most 3D printer fires seem to be due to overheating components. Not …read more

Robot Dances to the Beat of New YouTube Subs

Posted on by

Sure, you could build some kind of numerical counter to keep track of new YouTube subscribers. But does an increasing digit display truly convey the importance of such an event? Of course not. What you need is something that recognizes this achievement for what it is and celebrates it with you. Something like Subby, the Interactive YouTube Subscriber Robot.

Whenever [brian brocken] gets a new subscriber, Subby’s little TV screen face lights up, and he either dances, salutes, or does another move within his impressive range of motion. [brian] wrote a Visual Basic app that searches his channel’s page for …read more

Gaming System Built With Kite, The DIY Android Kit

Posted on by

As a gamer, [Lexie Dostal] dreamed of a smartphone that was a viable gaming platform: something with enough power to run the games and emulators he was interested in, with the controls to make playing them feel natural. So when he got his hands on an early version of Kite, the modular open hardware platform designed to be hacked and customized, that’s exactly what he decided to build. The Kite kit would provide the touch screen and Android-equipped motherboard, he just needed to design a case and integrate controls to make it a real gaming device.

The case design [Lexie] …read more

Animated Bluetooth Bike Turn Signals

Posted on by

Tired of risking his life every time he had to signal a turn using his hands while riding his bicycle in rainy Vancouver, [Simon Wong] decided he needed something a bit higher tech. But rather than buy something off the shelf, he decided to make it into his first serious Arduino project. Given the final results and the laundry list of features, we’d say he really knocked this one out of the park. If this is him getting started, we’re very keen to see where he goes from here.

So what makes these turn signals so special? Well for one, …read more

Programmable Air Makes Robotics A Breeze

Posted on by

[Amitabh] was frustrated by the lack of options for controlling air pressure in soft robotics. The most promising initiative, Pneuduino, seemed to be this close to a Shenzhen production run, but the creators have gone radio silent. Faced with only expensive alternatives, he decided to take one for Team Hacker and created Programmable Air, a modular system for inflatable and vacuum-based robotics.

The idea is to build the cheapest, most hacker-friendly system he can by evaluating and experimenting with all sorts of off-the-shelf pumps, sensors, and valves. From the looks of it, he’s pretty much got it dialed in. Programmable …read more

It’s Not Morning Until Green o’clock

Posted on by

[JohnathonT] has a two-year-old who can’t reliably tell time just yet. Every morning, he gets up before the rooster crows and barges into his parents’ room, ready to face the day.

In an effort to catch a few more Zs, [JohnathonT] built a simple but sanity-saving clock that tells time in a visual, kid-friendly way. Sure, this is a simple build. But if a toddler is part of your reality, who has time to make one from logic gates? The hardware is what you’d expect to see: Arduino Nano, a DS1307 RTC, plus the LEDs and resistors. We think an …read more
