A Jukebox For The 21st-Century Kit Blends Raspberry Pi, Sonos, QR Codes

When [Chris Campbell]’s children wanted to play an album in the background over dinner, switching the outputs on his family’s Sonos sound system was perhaps too involved for their budding mastery of technology. This got him thinking about using kid-friendly inputs so they could explore his music collection. Blending QR codes, some LEGO, and a bit of arts and crafts, a kid-friendly QR code reader media controller comes out!

Working with a Raspberry Pi 3 Model B and a cheap camera, [Campbell] whipped up some code to handle producing and reading the QR codes — though he’s running the media …read more http://pje.fyi/QH3khG

Pulling Music Out Of Thin Air with a Raspberry Pi

Pianos are great instruments, but being rather heavy and requiring a fair amount of space they are certainly not known for their convenience. Sure, there are more portable varieties available, but they rarely resemble the elegance and classiness of a grand piano. One option is of course to build a downscaled version yourself — and since you’re already customizing the instrument, why stop at the way you play it. [2fishy] didn’t stop there either and ended up with a wooden, space friendly, light controlled piano housing a Raspberry Pi.

Inspired by the concept of a laser harp, [2fishy] followed the …read more http://pje.fyi/QGZpGS

Cloning the Echo Show With a Fabric Wrapped Pi

After seeing an Echo Show in the flesh plastic, [anonteapot] was inspired to create his own take on Amazon’s latest on-ramp to their ecosystem. He had the Raspberry Pi and a touch screen, but not much else. He doesn’t even have a dedicated work area at home, much less something as exotic as a 3D printer to run off a custom case. For this decidedly low-tech build, all that was required tool-wise was a razor blade knife and a screwdriver.

The majority of the device, which he refers to as the PiShow, is made of hand-cut pieces of MDF. In …read more http://pje.fyi/QGHXYm

Pi Zero Gives Telescope Hands Free Focus

It seems like [Jason Bowling] never gets tired of finding new ways to combine the Raspberry Pi with his love of the cosmos. This time he’s come up with a very straightforward way of focusing his Celestron 127SLT with everyone’s favorite Linux SBC. He found the focus mechanism on the scope to be a bit fiddly, and operating it by hand was becoming a chore. With the Pi Zero and a stepper motor, he’s now able to focus the telescope with more accuracy and repeatability than clumsy human fingers will be able to replicate.

On this particular type of telescope, …read more http://pje.fyi/QG7vcK

A Grandfather Clock BarBot

As the saying goes, it’s five o’clock somewhere; when the clock finally strikes the hour, that same clock can pour you a drink thanks to redditor [Diggedypomme].

This bar-clock can dispense beverages with up to four different spirits and four mixers, and takes orders over voice, keyboard, or web-controls. A belt-driven drink loading platform pushes out through a spring-loaded door and once the vessel is in place and the order received, peristaltic pumps dispense the spirits while servos open taps for the mixers — a far easier method to administer the often carbonated liquids. A Raspberry Pi acts as this …read more http://pje.fyi/QDgMkB

Putting the Pi In Piano

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 …read more http://pje.fyi/QDWfG9

More Than Just An Atari Look-Alike

The Raspberry Pi has been a boon for hackers with a penchant for retro gaming. Redditor [KaptinBadkruk] Wanted to get on board the game train and so built himself an Atari 2600-inspired Raspberry Pi 3 console!

A key goal was the option to play Nintendo 64 titles, so [KaptinBadkruk] had to overclock the Pi and then implement a cooling system. A heatsink, some copper pads, and a fan from an old 3D printer — all secured by a 3D printed mount — worked perfectly after giving the heatsink a quick trim. An old speaker and a mono amp from Adafruit …read more http://pje.fyi/QD5lsy
