Scratch Built Media Player Channels 1980s Design

No, you aren’t having a look at a 30 12 months outdated Teac graphic equalizer that someone changed. The MWA-002 Community Tune Participant created by way of [GuzziGuy] is constructed fully from new elements, and simply ranks up there with one of the maximum stunning items of homebrew audio tools we’ve ever observed. Combining modular hardware with fashionable production tactics, this 1980s impressed construct is a testomony to how a long way we’ve come with regards to what’s conceivable for the devoted hacker and maker.

The enclosure, even though it appears to be like the entire global like a repurposed piece of antique hardware, used to be constructed with the assistance of a CNC router. It’s constituted of items of forged oak, plywood, and veneered MDF that experience all been meticulously routed out and lower. Even the entrance panel textual content used to be engraved with the CNC after which stuffed in with black paint to make the letters pop.

Internally, the MWA-002 is powered by way of a Raspberry Pi 3 operating Mopidy to play each native tracks and streaming audio. No longer glad with the Pi’s integrated features, [GuzziGuy] is the use of a Behringer UCA202 to supply CD-quality audio, which is then fed right into a TPA3116 amplifier. In flip, the output from the amplifier is terminated in a suite of feminine jacks at the participant. Similar to the stereo apparatus of yore, this participant is designed to be attached to a bigger audio machine and doesn’t have any interior audio system.

The main show is a 256×64 Futaba GP1212A02A FVD which has that era-appropriate glow whilst nonetheless handing over fashionable options. [GuzziGuy] says it used to be harder to interface with this I2C show than the LCDs he used up to now because of the loss of to be had libraries, however we expect the general product is evidence it used to be definitely worth the effort. He purchased each the VFD spectrum analyzer and LED VU meter as turn-key modules, however the middle equalizer controls are totally customized; with twin MCP3008 ADCs to learn the state of the sliders and the Linux Audio Developer’s Easy Plugin API (LADSPA) to tweak the Pi’s audio output accordingly.

We’re no strangers to stunning items of audio tools right here at appmarsh.com, however in most cases talking, maximum initiatives contain modernizing or augmenting an current instrument. Whilst the ones initiatives are to be admired, the engineering that is going into developing one thing of this caliber from modular elements and uncooked development fabrics is truly an accomplishment on an entire other degree.
