Arduino Keyboard is Gorgeous Inside and Out

While the vast majority of us are content to plod along with the squishy chiclet keyboards on our laptops, or the cheapest USB membrane keyboard we could find on Amazon, there’s a special breed out there who demand something more. To them, nothing beats a good old-fashioned mechanical keyboard, where each key-press sounds like a footfall of Zeus himself. They are truly the “Chad” of the input device world.

But what if even the most high end of mechanical keyboards doesn’t quench your thirst for spring-loaded perfection? In that case, the only thing left to do is design and build your own. [Matthew Cordier] recently unveiled the custom mechanical keyboard he’s been working on, and to say it’s an elegant piece of engineering is something of an understatement. It may even better inside than it does on the outside.

The keyboard, which he is calling z.48, is based around the Arduino Pro Micro running a firmware generated on kbfirmware.com, and features some absolutely fantastic hand-wiring. No PCBs here, just a rainbow assortment of wire and the patience of a Buddhist monk. The particularly attentive reader may notice that [Matthew] used his soldering iron to melt away the insulation on his wires where they meet up with the keys, giving the final wiring job a very clean look.

Speaking of the keys, they are Gateron switches with DSA Hana caps. If none of those words mean anything to you, don’t worry. We’re through the Looking Glass and into the world of the keyboard aficionado now.

Finally, the case itself is printed on a CR-10 with a 0.3 mm nozzle and 0.2 mm layers giving it a very fine finish. At 70% infill, we imagine it’s got a good deal of heft as well. [Matthew] mentions that a production case and a PCB are in the cards for the future as he hopes to do a small commercial run of these boards. In the meantime we can all bask in the glory of what passes for a prototype in his world.

We’ve seen some exceptionally impressive mechanical keyboards over the years, including the occasional oddity like the fully 3D printed one and even one that inexplicably moves around. But this build by [Matthew] has to be one of the most elegant we’ve ever come across.

Water speakers enhanced with an Arduino Mega

Maker “cool austin” is a fan of water speakers, which pulse jets of water inside plastic enclosures to the beat of your music, but thought they could be improved.

What he came up with is a multi-tower setup that not only dances with light and water to the beat of the music playing, but splits up the pulses into frequencies a la a VU meter.

The project uses an Arduino Mega—chosen because it has sufficient PWM outputs to control the water and lights in five of these enclosures via MOSFETs—to output signals to the water units for an excellent audio-visual display.

Water speakers from the store are great to watch, but I felt they could do more. So many years ago I had modified a set to show the frequency of music playing. At the time I used the Color Organ Triple Deluxe II, combined with a set of photocells potentiometers and transistors I was able to get a set of 3 speakers to function.

I then a few years ago had heard about the IC MSGEQ7 which has the ability to separate audio into 7 data values for an Arduino to read. I utilize an Arduino mega 2560 in this project because it has the required number of PWM pins to drive five water towers.

You can find more details on the water speaker equalizer here, and see it in action below!

Video game head tracking with Wii Remote camera

While the Nintendo Wii has been on the market for well over 10 years, its controllers continue to provide a variety of tools for hacking. One component you may want to consider for your next hack is the camera from the Wii Remote, which senses the position of nearby infrared light spots and outputs them as X/Y coordinates via I²C.

While that may instantly set off multiple use ideas, if you need inspiration, be sure to check out this setup by Jack Carter. He mounted one of these cameras to the top of a computer screen, and uses it to track an IR LED mounted to the top of his headset.

From there, an Arduino Uno translates this information as joystick inputs to the computer, which is then configured to control an in-game camera as seen in the video here.

Creeper Detector

For a couple years, I helped the Children's Museum of Bozeman develop curriculum for their STEAMlab. I was always looking for fun ways to engage kids with electronics and coding. Minecraft is an easy way to get kids in the door and there are tons of resources for using it in fun and educational ways...
