Telephone Plays The Songs Of Its People

Music, food, and coding style have one thing in common: we all have our own preferences. On the other hand, there are arguably more people on this planet than there are varieties in any one of those categories, so we rarely fail to find like-minded folks sharing at least some …read more

Arduino Shield Makes Driving Nixies Easy

Nixie tubes are adored by hackers across the world for their warm glow that recalls an age of bitter nuclear standoffs and endless proxy wars. However, they’re not the easiest thing to drive, requiring high voltages that can scare microcontrollers senseless. Thankfully, it’s possible to score an Arduino shield that …read more

Printed Perching Pals Proliferate

Anansi in African folktale is a trickster and god of stories, usually taking physical form of a spider. Anansi’s adventures through oral tradition have adapted to the situation of people telling those stories, everything ranging from unseasonable weather to living a life in slavery. How might Anansi adapt to the …read more

Vintage Atari Becomes Modern Keyboard

The modern keyboard enthusiast is blessed with innumerable choices when it comes to typing hardware. There are keyboards designed specifically for gaming, fast typing, ergonomics, and all manner of other criteria. [iot4c] undertook their own build for no other reason than nostalgia – which sounds plenty fun to us.

An …read more

Driving a Controllerless LCD With the Humble Arduino Uno

These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Load up the right libraries and you’re up and running in a matter of minutes. However, turn your attention …read more

State Of The Art Big Mouth Alexa Bass

Hackers seem intent on making sure the world doesn’t forget that, for a brief shining moment, everyone thought Big Mouth Billy Bass was a pretty neat idea. Every so often we see a project that takes this classic piece of home decor and manages to shoehorn in some new features or capabilities, and with the rise of voice controlled home automation products from the likes of Amazon and Google, they’ve found a new ingredient du jour when preparing stuffed bass.

[Ben Eagan] has recently completed his entry into the Pantheon of animatronic fish projects, and while we’ll stop short of …read more

Arduino Enters the Cloud

Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.

The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can …read more

Custom Jig Makes Short Work of Product Testing

When you build one-off projects for yourself, if it doesn’t work right the first time, it’s a nuisance. You go back to the bench, rework it, and move on with life. The equation changes considerably when you’re building things to sell to someone. Once you take money for your thing, you have to support it, and anything that goes out the door busted is money out of your pocket.

[Brian Lough] ran into this fact of life recently when the widget he sells on Tindie became popular enough that he landed an order for 100 units. Not willing to cut …read more

Pen Plotter From Salvaged Printer Parts

Like many of us, [Benjamin Poilve] was fascinated when he took apart a broken printer. He kept the parts, but unlike most of us, he did something with them, building a neat little plotter called the Liplo. Most pen plotters work by moving the pen on two axes, but [Benjamin] took a different approach, using the friction drive bars from the printer to move the paper on one axis, and a servo to move the pen on the other. He’s refined the design from its initial rough state to create a very refined final product that uses a combination of …read more
