The Gorgeous Hardware We Can’t Take Our Eyes Away From

High resolution digital cameras are built into half of the devices we own (whether we want them or not), so why is it still so hard to find good pictures of all the incredible projects our readers are working on? In the recently concluded Beautiful Hardware Contest, we challenged you to take your project photography to the next level. Rather than being an afterthought, this time the pictures would take center stage. Ranging from creative images of personal projects to new ways of looking at existing pieces of hardware, the 100+ entries we received for this contest proved that there’s more beauty in a hacker’s parts bin than most of them probably realize.

As always, it was a struggle to narrow down all the fantastic entries to just a handful of winners. But without further adieu, let’s take a look at the photos that we think truly blurred the line between workbench and work of art:

Putting The Pi In Piano

January 31, 2018 by James Hobson 10 Comments

Working on a PhD in composition, [Stephen Coyle] spends a fair bit of time at his electric keyboard. Setting himself up to work can be a bit of a task, so he felt he could improve the process and make it easy as Pi.

Finding it an odious task indeed to use notation software, connecting his laptop to his keyboard is a must — avoiding a warren of wires in the move is a similar priority. And, what if he could take advantage of the iPad’s unique offerings too? Well, a Raspberry Pi Zero W running Ravelox — an RTP MIDI protocol — makes his music available on his network to record on whichever device he pleases.

Keyboard Composes Its Own Music

Summer is right around the corner and all the final projects from electronic design classes are rolling into the tip line. This time, we’ve got [Chaorong] and [Siyu]’s auto-composing keyboard from their time in ECE4760 at Cornell.

The keyboard has two modes: a ‘happy’ mode and a ‘tender’ mode, the difference being the tender mode is slower and sounds a little like a lullaby. After two keys are pressed, the ATMega644 figures out what key it should play in and starts generating a random-ish sounding song using a Markov probability matrix.

There’s a third option for the keyboard as well: play a short melody and the software will loop through a few permutations of the melody. After the break, you can see [Siyu] play Ode to Joy and have the autocomposer improvise around the tune. Very, very nice work and we can’t wait to see more senior design projects hit the tip line.
