The humble capo has graced the gig bags of performing musicians for decades, clamping down to change the overall key of a guitar in a single, swift motion. Now, a new take on the capo opens up whole new musical worlds of alternate tunings.Continue Read… Continue reading ‘Guitar capo 2.0’ gives you five different note options per string
Certain among our readership will no doubt remember attaching a playing card to the front fork of one’s bicycle so that the spokes flapped the card as the wheel rotated. …read more Continue reading This Found-Sound Organ Was Made with Python and a Laser Cutter
Brabus has been known for concocting some over-the-top vehicles — in fact, it’s not really known for much of anything else. This time, it positively outdoes itself, though, debuting the all-new 800 Adventure XLP Superwhite. What was once an innocent-en… Continue reading Brabus “Superwhite” G pickup might be 2022’s most illogical auto
Even with fancy smartphone apps and custom-built tuners, tuning a guitar can be a tedious process, especially for the beginner. Pluck a string, figure out if the note is sharp …read more Continue reading Handheld Bot Takes the Tedium Out of Guitar Tuning
We all know that light and sound are wave phenomena, but of very different kinds. Light is electromechanical in nature, while sound is mechanical. Light can travel through a vacuum, …read more Continue reading Acousto-Optic Filter Uses Sound to Bend Light
On today’s episode of “Will it MIDI?” we have the common slide whistle. Spoiler alert: yes, it will, and the results are just on the edge of charming and — well, a little weird.
As maker [mitxela] points out, for …read more
We wager you haven’t you heard the latest from ultrasonics. Sorry. [Lindsay Wilson] is a Hackaday reader who wants to share his knowledge of transducer tuning to make tools. The bare unit he uses to demonstrate might attach to the bottom of an ultrasonic cleaner tank, which have a different construction than the ones used for distance sensing. The first demonstration shows the technique for finding a transducer’s resonant frequency and this technique is used throughout the video. On the YouTube page, his demonstrations are indexed by title and time for convenience.
For us, the most exciting part is when …read more

Digitally stored music is just data. But not long ago, music was analog and required machines with moving parts. If you have never owned a record player, you at least know what they look like, now that there’s a(nother) vinyl revival. What you may not be aware of is that the player’s stylus needs to be aligned. It makes sense, that hypersensitive needle can’t be expected to perform well if it’s tearing across a record like a drift racer.
There are professional tools for ensuring alignment, but it’s not something you’ll need each day. [Ali Naci Erdem] shows us his …read more
[amazingdiyprojects] has been making lots of test flights in his crazy eight propeller gasoline powered danger bucket.
We last covered the project when he had, unfortunately, wrecked the thing in a remote-controlled test flight. He later discovered that the motor’s crankshaft bearings had, well, exploded. The resulting shrapnel destroyed the motor and crashed the drone. He described this failure mode as “concerning”.
Also concerning is the act of stepping into the seat once all the propellers are started up. He tags this as “watch your step or die”. Regardless, he also describes flying in the thing as so incredibly fun …read more

After years of cutting my hands on the exposed threads of my Prusa Mendel i2, it was time for a long overdue upgrade. I didn’t want to just buy a new printer because it’s no fun. So, I decided to buy a new frame for my printer. I settled on the P3Steel, a laser cut steel version of the Prusa i3. It doesn’t suffer from the potential squaring problems of the vanilla i3 and the steel makes it less wobbly than the acrylic or wood framed printers of similar designs.
I expected a huge increase in reliability and print quality …read more
