Planet Arduino

What’s the use of waiting around for something to break in order to hack into something else? As long as it’s just sitting around not being used, who cares? [OmniSaiRen] had a  Behringer MIDI controller just taking up space. Instead of selling it, they decided to build it into something they would definitely use — a multi-volume controller with mute keys and other useful macros.

After gutting the case, [OmniSaiRen] gave it a couple coats of glossy white paint that looks really nice with the black keycaps and knobs. The plan was to use the original encoders, but [OmniSaiRen] replaced them with potentiometers when they couldn’t get the encoders working with the Arduino Nano. We are sad to report that Cherry Blues only made it to the build because they have all black housings and were also lying around taking up space, but maybe [OmniSaiRen] will grow to love them.

If you’re tired of all the mousing and clicking it takes to turn down this or that volume, you need to build one of these things. It runs on deej, an open source volume mixer that works with Linux and Windows, so what are you waiting for? If you only want a single hardware volume knob, you can’t go wrong dialing it in rotary style.

[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 as it is cool looking. Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, and the key map just updates automatically for the chosen program. At the heart of this build is an Arduino Pro Micro and 20 of the loudest key switches ever made — Cherry MX blues. We like that it manages to look like toy cash register and a serious peripheral all at once — it probably has something to do with those way-cool circular keycaps that were made on a resin printer.

We’re glad that [FabroLabs] laid down such a comprehensive and open build guide during the process of making this macro keyboard. The average hacker can learn a lot from industrial designers who show their work. Remember the time [Eric Strebel] showed us all how to improve our foam board design game?
