Spoofing an Analog Rotary Knob with an ATtiny, and Vampiric Power

[Mitxela]’s repair of a Roland JV-1080 (a rack-mounted 90s-era synthesizer) sounds simple: replace a broken rotary encoder on the front panel. It turned out to be anything but simple, since the part in question is not today’s idea of a standard rotary encoder at all. The JV-1080 uses some kind …read more

Multi-Volume Knob Gives All Your Programs a Turn

We’ve all been there. You’re manning the battle station, deep in the sim-racing or some other n00b-pwning zone and suddenly some loudmouth blows out your eardrums over Discord. It’s insulting to have to stop what you’re doing to find the right Windows volume slider. So why do that? Build [T3knomanzer]’s …read more

Software Shortcut Keyboard Registers Many Macros

[FabroLabs Technologies] is an industrial designer who uses several creative-type software programs in a given day. Unfortunately, they all have slightly different shortcut schemes, and trying to remember all the different modifiers is a waste of time better spent elsewhere.

This lovely little macro keyboard is every bit as useful …read more

Baby Keyboard Is Really Three Boards

Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. This bad boy built by [andyclymer] can be configured three different ways, depending on what kind of control you’re after.

As designed, the PCB can be used as a six-switch macro keyboard, or …read more

Sort the Rainbow with an Algorithm Machine

When you’re trying to learn how an algorithm works, it’s not always easy to visualize what’s going on. Well, except for maybe binary sort, thanks to the phone book. Professor [thatguyer] is a computer science teacher who wanted a way to help his students visualize the process of algorithms and …read more

Micro Macro Keyboard Makes a Major Difference

Media keyboards are nice in theory. But in practice they never have all the keys you want, and they almost always have a few you don’t. Sure, you could maybe reassign the ones you don’t use, but then the caps are wrong, and it’s a whole thing. So really, the …read more

Square Laser Harp is Hip

You know, we hadn’t realized how tired we were of vertical laser harps until we saw [Jonathan Bumstead]’s entry into the 2019 Hackaday Prize. It’s all well and good to imitate the design of the inspiring instrument. But the neat thing about synths is that they aren’t confined to the …read more

A Classy USB Knob For The Discerning Computerist

The keyboard and mouse are great, we’re big fans. But for some tasks, such as seeking around in audio and video files, a rotary encoder is a more intuitive way to get the job done. [VincentMakes] liked the idea of having a knob he could turn to adjust his system …read more
